##### Table of Contents

|development cost | For a given period, costs incurred to obtain access to proved reserves and to provide facilities for extracting, treating, gathering and storing the oil and gas.
|------------------ | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



|finding cost | For a given period, costs incurred in identifying areas that may warrant examination and in examining specific areas that are considered to have prospects of containing oil
and gas reserves, including costs of drilling exploratory wells and exploratory-type test wells. Finding cost is also known as exploration cost.
|-------------- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|lifting cost | For a given period, costs incurred to operate and maintain wells and related equipment and facilities, including applicable operating costs of support equipment and
facilities and other costs of operating and maintaining those wells and related equipment and facilities. Lifting cost is also known as production cost.
|-------------- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|natural gas liquids | Hydrocarbons that can be extracted in liquid form together with natural gas production. Ethane and pentanes are the predominant components, with other heavier hydrocarbons
also present in limited quantities.
|--------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|offshore | Areas under water with a depth of five meters or greater.
|---------- | ---------------------------------------------------------



|onshore | Areas of land and areas under water with a depth of less than five meters.
|--------- | --------------------------------------------------------------------------



|primary distillation capacity | At a given point in time, the maximum volume of crude oil a refinery is able to process in its basic distilling units.
|------------------------------- | ----------------------------------------------------------------------------------------------------------------------



|proved reserves | Under the SEC reserve rules, proved reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable
certainty to be economically producible  from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations  prior to the time at which contracts providing the right to
operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must
be reasonably certain that it will commence the project within a reasonable time.
|----------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) The area of the reservoir considered as proved includes:
| | ------------------------------------------------------------



| | (A) The area identified by drilling and limited by fluid contacts, if any, and (B) Adjacent undrilled portions of the reservoir that can, with
reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as
| | -------------------------------------------------------------------------------------------------------------------------------------



2

##### Table of Contents

| | seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gas
cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid
injection) are included in the proved classification when:
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the
operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and (B) The
project has been approved for development by all necessary parties and entities, including governmental entities.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be
the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are
defined by contractual arrangements, excluding escalations based upon future conditions.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|reserve-to-production ratio | For any given well, field or country, the ratio of proved reserves to annual production of crude oil or, with respect to natural gas, to wellhead production excluding flared
gas.
|----------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|sales gas | Marketable production of gas on an as sold basis, excluding flared gas, injected gas and gas consumed in operations.
|----------- | ----------------------------------------------------------------------------------------------------------------------



|undeveloped reserves | Under the SEC reserve rules, undeveloped reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells
where a relatively major expenditure is required for recompletion.
|---------------------- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production
when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (ii) Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are
scheduled to be drilled within five years, unless the specific circumstances, justify a longer time.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or
other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, or by other evidence using reliable technology establishing reasonable
certainty.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|water cut | For a given oil region, the percentage that water constitutes of all fluids extracted from all wells in that region.
|----------- | --------------------------------------------------------------------------------------------------------------------

Risk Factors

Our business is primarily subject to various changing competitive, economic and social conditions. Such changing
conditions entail certain risks, which are described below.

Risks Related to Macro Economic Conditions

Our operations may be adversely affected by the international and domestic economic conditions. As the oil and gas
industry is sensitive to macro-economic trends, oil and gas prices tend to fluctuate along with the change of macro-economic conditions. We may experience pricing pressure on our refined products in recessionary periods, which would have an adverse
effect on our profitability. These factors may also lead to intensified competition for market share, with consequential potential adverse effects on volumes. There has been an uptrend in Chinas overall inflation rate in recent years.
Notwithstanding the measures taken by the PRC government to control inflation, China may continue to experience inflation in the near term and our operating costs may become higher than anticipated. The financial and economic situation may also have
a negative impact on third parties with whom we do, or may do, business. Any of these factors may adversely affect our financial condition, results of operations and liquidity.

Risks Related to Competition

The oil, gas and
petrochemicals industries are highly competitive. There is strong competition, both within the oil and gas industry and with other industries, in supplying the fuel needs of commercial, industrial and residential markets. Competition puts pressure
on product prices, affects oil products marketing and requires continuous management focus on identifying new trends, reducing unit costs and improving efficiency. The implementation of our growth strategy requires continued technological advances
and innovation, including advances in exploration, production, refining, petrochemicals manufacturing technology and advances in technology related to energy usage. Our performance could be impeded if competitors developed or acquired intellectual
property rights to technology that we required or if our innovation lagged the industry.

The eastern and
southern regions of China have a higher demand for refined products and chemical products than the western and northern regions. Most of our refineries and chemical plants are located in the western and northern regions of China. We incur relatively
higher transportation costs for delivery of our refined products and chemical products to certain areas of the eastern and southern regions from our refineries and chemical plants in western and northern China. We face strong competition from other
domestic oil companies. As a result, we expect that we will continue to encounter difficulty in increasing our sales of refined products and chemical products in these regions.

Risks Related to Outbound Investments

We are subject to
various political, legal and regulatory environments in foreign developing countries where we operate, some of which are known to be unstable and differ in certain significant respects from those prevailing in developed countries. Main factors
affecting our outbound investments include unstable political situation, unstable tax policies and unstable regulatory regime. CNPC, our controlling shareholder, and its affiliates and subsidiaries may choose to undertake, without our involvement,
overseas investments and operations in the oil and gas industry, including exploration and production of oil and gas, refining and transportation and trading and liquefied natural gas, or LNG projects or other business activities. CNPCs
overseas asset portfolio includes oil and gas development projects in Sudan, Iran, Cuba and Syria, which countries are the subject of U.S. sanctions. Certain U.S.-based investors may not wish to invest, and have proposed or adopted divestment or
similar initiatives regarding investments, in companies that do business with countries that are the subject of U.S. sanctions. These investors may not wish CNPC to make investments or conduct activities in the countries that are the subject of U.S.
sanctions, and may divest their investment in us because of our relationship with CNPC and its investments and activities in those countries that are the subject of U.S. sanctions. As a result, the trading prices of our ADSs may be adversely
affected.

##### Table of Contents

In July 2012, the U.S. Treasury Departments Office of Foreign Assets
Control, OFAC, added Bank of Kunlun Co., Ltd., or Kunlun Bank, an affiliate of our company due to common control by CNPC, to its List of Foreign Financial Institutions Subject to Part 561 pursuant to the Comprehensive Iran Sanctions,
Accountability, and Divestment Act of 2010. OFAC reported that Kunlun Bank provided financial services to at least six Iranian banks that were on OFACs sanctions list during 2012. These financial services included holding accounts, making
transfers, and in particular, transfer of a total of US$0.1 billion for Bank Tejarat during early 2012, and paying letters of credit on behalf of the designated banks. Kunlun Bank has not informed us the revenue and profit it generated from such
activities in relation to Iran and whether it will discontinue such activities. Our company has no involvement in or control over the activities of Kunlun Bank or CNPC and CNPC subsidiaries and affiliates, and we have never received any revenue or
profit derived from these activities.

Risks Related to Government Regulation

Our operations, like those of other PRC oil and gas companies, are subject to extensive regulations and control by the PRC
government. These regulations and control affect many material aspects of our operations, such as exploration and production licensing, industry-specific and product-specific taxes and fees and environmental and safety standards. As a result, we may
face significant constraints on our ability to implement our business strategies, to develop or expand our business operations or to maximize our profitability. Our business may also be affected by future changes in certain policies of the PRC
government with respect to the oil and gas industry.

Currently, the PRC government must approve the
construction and major renovation of significant refining and petrochemical facilities as well as the construction of significant crude oil, natural gas and refined product pipelines and storage facilities. We presently have several significant
projects pending approval from the relevant government authorities and will need approvals from the relevant government authorities in connection with several other significant projects. We do not have control over the timing and outcome of the
final project approvals.

Because PRC laws, regulations and legal requirements dealing with economic matters
continue to evolve, and because of the limited volume of published judicial interpretations and the non-binding nature of prior court decisions, the interpretation and enforcement of these laws, regulations and legal requirements involve some
uncertainty. Because the PRC Company Law is different in certain important aspects from company laws in the United States, Hong Kong and other common law jurisdictions, and because the PRC securities laws and regulations are still at an early stage
of development, you may not enjoy shareholders protections that you may be entitled to in other jurisdictions.

Risks Related to
Controlling Shareholder

As of December 31, 2012, CNPC beneficially owned approximately 86.507% of our
share capital. This ownership percentage enables CNPC to elect our entire board of directors without the concurrence of any of our other shareholders. Accordingly, CNPC is in a position to:



| |  |  | control our policies, management and affairs;
| | - |  | ---------------------------------------------



| |  |  | subject to applicable PRC laws and regulations and provisions of our articles of association, affect the timing and amount of dividend payments and
adopt amendments to certain of the provisions of our articles of association; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | otherwise determine the outcome of most corporate actions and, subject to the regulatory requirements of the jurisdictions in which our shares are
listed, cause our company to effect corporate transactions without the approval of minority shareholders.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

CNPCs interests may sometimes conflict with those of some or all of our minority shareholders. We cannot assure you that CNPC, as our controlling shareholder, will always vote its shares in a way
that benefits our minority shareholders.

##### Table of Contents

In addition to its relationship with us as our controlling shareholder, CNPC
by itself or through its affiliates also provides us with certain services and products necessary for our business activities, such as construction and technical services, production services, materials supply services, various logistics services
and financial services. The interests of CNPC and its affiliates as providers of these services and products to us may conflict with our interests.

Risks Related to Pricing and Exchange Rate

Our operations
are affected by the volatility of prices for crude oil, refined products and natural gas. We set our crude oil median prices monthly based on the Singapore trading prices for crude oil.

Historically, international prices for crude oil have fluctuated widely in response to changes in many factors, such as
global and regional economy and politics and supply and demand for crude oil. We do not have, and will not have, control over the factors affecting international prices for crude oil. Fluctuations in crude oil prices have a significant impact in our
results of operations. A decline in crude oil prices may reduce revenues from, and may result in a loss in, our exploration and production segment. Further, if crude oil prices remain at a low level for a prolonged period, our company has to
determine and estimate whether our oil and gas assets may suffer impairment losses and, if so, the amount of the impairment losses. An increase in crude oil prices may, however, increase the production costs of refined products reduce demand for our
products and affect our operating profits.

Since 2008, the PRC government has further improved its refined oil
pricing mechanism. Based on the refined oil pricing mechanism, when there is a change in the average crude oil price in the international market during a given time period, the PRC government can adjust the refined oil prices. However, when
international crude oil price experiences sustained increases or becomes significantly volatile, the PRC government may increase its control over the refined oil prices. As a result, the regulation on refined product prices by the PRC government may
reduce our profit and cause our refining assets to suffer impairment losses.

We negotiate the actual
ex-factory price with natural gas users within the benchmark price and the adjustment range set by the PRC government. When the benchmark price is lower than the international natural gas price, the cost of our imported natural gas will be higher
than the selling price of our natural gas, which may reduce our revenues or cause our natural gas assets to suffer impairment losses.

We receive most of our revenues in Renminbi. A portion of our Renminbi revenues must be converted into other currencies to meet our foreign currency obligations. The existing foreign exchange limitations
under the PRC laws and regulations could affect our ability to obtain foreign exchange through debt financing, or to obtain foreign exchange for capital expenditures. The value of Renminbi against U.S. dollar and other currencies may fluctuate and
is affected by, among other things, changes in Chinas political and economic conditions. On July 21, 2005, the PRC government introduced a floating exchange rate system to allow the value of the Renminbi to fluctuate within a regulated
band based on market supply and demand and by reference to a basket of foreign currencies. Because most of our purchases of crude oil and our outbound investments are settled in foreign currencies, the exchange rates between RMB and U.S. dollars and
any other relevant foreign currencies may have an effect on our crude oil purchase costs and investment costs.

Risks Related to
Environmental Protection and Safety

Compliance with changes in laws, regulations and obligations relating
to climate change or environmental protection could result in substantial capital expenditures and reduced profitability from changes in operating costs.

A number of provinces in which our oil and gas exploration and production activities are located have promulgated environment protection regulations, which set forth specific abandonment and disposal
processes for oil and gas exploration and production activities. We have established standard abandonment procedures in response to the issuance of these provincial regulations. We have included under our asset



11

##### Table of Contents

retirement obligations the costs for these abandonment activities and this asset retirement obligation is based on our best estimate of future abandonment expenditures. In addition, PRC central
government or other provincial governments may enact similar regulations or stricter environmental protection regulations. Such potential new regulations could increase our asset retirement costs.

The process of gasoline and diesel fuel quality upgrade is gradually accelerating in China. Currently, the China IV
standard for auto-use gasoline was officially issued and put into effect in March 2011, and the China IV standard for auto-use diesel fuel was published on July 5, 2012. In addition, the Chinese government imposed new diesel fuel standard to
reduce sulfur content in regular diesel fuel from 2000 ppm to 350 ppm starting June 30, 2013. Some local governments have implemented their local gasoline and diesel fuel standards, some of which are in line with the Euro IV standard. New
governmental requirements to improve oil quality impose challenges to our refining and chemicals segment and could increase our costs in oil refining.

Exploring for, producing and transporting crude oil and natural gas and producing and transporting refined products and chemical products involve many hazards. These hazards may result in:



| |  |  | fires;
| | - |  | ------



| |  |  | explosions;
| | - |  | -----------



| |  |  | spills;
| | - |  | -------



| |  |  | blow-outs; and
| | - |  | --------------



| |  |  | other unexpected or dangerous conditions causing personal injuries or death, property damage, environmental damage and interruption of operations.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------

Some of our oil and natural gas fields are surrounded by residential areas or located in
areas where natural disasters, such as earthquakes, floods and sandstorms, tend to occur more frequently than in other areas. As with many other companies around the world that conduct similar businesses, we have experienced accidents that have
caused property damage and personal injuries and death.

Significant operating hazards and natural disasters
such as earthquake, tsunami and health epidemics may cause partial interruptions to our operations and property and environmental damage that could have an adverse impact on our financial condition.

Risks Related to Climate Change

In recent years, the oil industry has faced an increasingly severe challenge imposed by the global climate change. Numerous international, domestic and regional treaties and agreements to restrict the
emission of greenhouse gas have been executed and become effective. If China or any other country in which we operate business remains committed to the reduction of the emission of greenhouse gas, the legal and regulatory requirements for that
purpose may lead to a substantial increase in our capital expenditures and tax expenses and in turn, an increase in our operating costs. As a result, our results of operations and our strategic investment may be adversely affected.

Risks Related to Insurance Coverage

Due to the fact that oil industry is susceptible to high and industry-specific risks in nature, the current ordinary commercial insurance cannot cover all the business areas in which we operate. We
maintain insurance coverage against some, but not all, potential losses. We may suffer material losses resulting from uninsurable or uninsured risks or insufficient insurance coverage.

Risks Related to Oil and Gas Reserves

The crude oil and
natural gas reserve data in this annual report are only estimates. The reliability of reserve estimates depends on a number of factors, assumptions and variables, such as the quality and quantity of our



12



---

##### Table of Contents

technical and economic data and the prevailing oil and gas prices applicable to our production, some of which are beyond our control and may prove to be incorrect over time. Results of drilling,
testing and production after the date of the estimates may require substantial upward or downward revisions in our reserve data. Our actual production, revenues and expenditures with respect to our reserves may differ materially from these estimates
because of these revisions.

We are actively pursuing business opportunities outside China to supplement our
domestic resources. For instance, we acquired certain overseas crude oil and natural gas assets from CNPC. We cannot assure you, however, that we can successfully locate sufficient alternative sources of crude oil supply or at all due to the
complexity of the international political, economic and other conditions. If we fail to obtain sufficient alternative sources of crude oil supply, our results of operations and financial condition may be materially and adversely affected.

Risks Related to Liquidity

We have tried our best endeavors to ensure an appropriate level of liquidity and financing ability. However, as we are currently undergoing constructions in response to a peak in our oil and gas reserves,
strengthening capacity building in key areas, constructing new, and expanding some existing, refinery and petrochemical facilities and constructing several natural gas and oil pipelines, we may have to make substantial capital expenditures and
investments. We cannot assure you that the cash generated by our operations will be sufficient to fund these development plans or that our actual future capital expenditures and investments will not significantly exceed our current planned amounts.
If either of these conditions arise, we may have to seek external financing to satisfy our capital needs. Our inability to obtain sufficient funding for our development plans could adversely affect our business, financial condition and results of
operations.

Risks Related to Effectiveness of Internal Control over Financial Reporting

SEC, as required by Section 404 of the Sarbanes-Oxley Act of 2002, adopted rules requiring every public company in
the United States to include a management report on such companys internal control over financial reporting in its annual report, which contains managements assessment of the effectiveness of the companys internal control over
financial reporting. Although our management concluded that our internal control over our financial reporting for the fiscal year ended December 31, 2012 was effective, we may discover other deficiencies in the course of our future evaluation
of our internal control over our financial reporting and may be unable to remediate such deficiencies in a timely manner. If we fail to maintain the adequacy of our internal control over financial reporting, we may not be able to conclude that we
have effective internal control over financial reporting on an ongoing basis, in accordance with the Sarbanes-Oxley Act. Moreover, effective internal control is necessary for us to produce reliable financial reports and is important to prevent
fraud. As a result, our failure to maintain effective internal control over financial reporting could result in the loss of investor confidence in the reliability of our financial statements, which in turn could harm our business and negatively
impact the trading prices of our ADSs, H Shares or A Shares.

Risks Related to Audit Reports Prepared by an Auditor who is not
Inspected by the Public Company Accounting Oversight Board

Auditors of companies that are registered with
the SEC and publicly traded in the United States, including our independent registered public accounting firm, must be registered with the United States Public Company Accounting Oversight Board, or the PCAOB, and are required by the laws of the
United States to undergo regular inspections by the PCAOB to assess their compliance with the laws of the United States and professional standards. Because the auditors of our company are located in the PRC, a jurisdiction where the PCAOB is
currently unable to conduct inspections without the approval of the Chinese authorities, the auditors of our company are not currently inspected by the PCAOB. As a result, investors do not have the



13



---

##### Table of Contents

benefits of PCAOB inspections. The inability of the PCAOB to conduct inspections of auditors in the PRC makes it more difficult to evaluate the effectiveness of our auditors audit
procedures or quality control procedures as compared to auditors outside the PRC that are subject to PCAOB inspections.

Introduction

History and Development of Our Company

Our legal name is



LOGO
 and its English translation is PetroChina Company Limited.

We are the
largest oil and gas producer and seller occupying a leading position in the oil and gas industry in the PRC and one of the largest companies in the world. We are engaged in a broad range of petroleum and natural gas related activities, including the
exploration, development, production and marketing of crude oil and natural gas; the refining of crude oil and petroleum products, as well as the production and marketing of basic petrochemical products, derivative chemical products and other
chemical products; the marketing of refined oil products and trading; and the transmission of natural gas, crude oil and refined oil products as well as the sale of natural gas.

Currently, substantially all of our crude oil and natural gas reserves and production-related assets are located in
China. Our exploration, development and production activities commenced in the early 1950s. Over more than six decades, we have conducted crude oil and natural gas exploration activities in many regions of China.

We commenced limited refining activities in the mid-1950s. Our chemicals operations commenced in the early 1950s. In the
early 1960s, we began producing ethylene. Our natural gas transmission and marketing activities commenced in Sichuan in southwestern China in the 1950s.

We have increased our efforts to pursue attractive business opportunities outside China as part of our business growth strategy to utilize both domestic and international resources to strengthen our
competitiveness. Since 2005, we have acquired interests in various oil and natural gas assets in several countries, which significantly expanded our overseas operations and effectively increased our oil and gas reserves and production volumes. We
are currently assessing the feasibility of making further investments in international oil and gas markets. At the same time, we have been gradually increasing the proportion of the imported crude oil.

In the year ended December 31, 2012, we imported approximately 465.6 million barrels of crude oil, as compared
to 441.2 million barrels and 359.1 million barrels of crude oil in the years ended December 31, 2011 and 2010, respectively.

We were established as a joint stock company with limited liability under the Company Law of the PRC on November 5, 1999 as part of a restructuring in which CNPC transferred to us most of the assets
and liabilities of CNPC relating to its exploration and production, refining and marketing, chemicals and natural gas businesses.

On April 7, 2000, we completed a global offering of H Shares and ADSs. In September 2005, we completed a follow-on offering of over 3 billion H Shares at the price of HK$6.00 per share. In October
2007, we issued 4 billion A Shares at an issue price of RMB16.7 per share. The A Shares were listed on the Shanghai Stock Exchange on November 5, 2007. As of December 31, 2012, CNPC beneficially owned 158,325,211,528 shares in
PetroChina, which include 291,518,000 H Shares indirectly held by CNPC through Fairy King Investments Limited, an overseas wholly owned subsidiary of CNPC, representing approximately 86.507% of the share capital of PetroChina.

Acquisitions

On October 16, 2011, we entered into a joint venture agreement with Beijing Enterprises Group
Company Limited and Hebei Natural Gas Company Limited for the formation of a joint venture named PetroChina Jingtang LNG Co., Ltd., or Jingtang LNG, in Tangshan City, Hebei Province. Jingtang LNG was incorporated in September 2012 with a registered
capital of RMB2,600 million. We will contribute approximately RMB1,326 million to Jingtang LNG for its 51% equity interest. The capital injection will be completed by October 2013.

In addition, we have launched a series of overseas acquisitions, for example:

In May 2012, we, jointly with Shell Canada Limited, Korea Gas Corporation, or KOGAS, and Mitsubishi Corporation invested
in a project to build and operate an LNG export terminal with an annual capacity of 12 million tons in Kitimat, British Columbia, Canada. We hold 20% equity interest in the project. Shell Canada Limited has a 40% equity interest in the project
while each of KOGAS and Mitsubishi Corporation holds a 20% interest.

On July 25, 2012, we entered into
an agreement with Qatar Petroleum and GDF Suez Qatar to acquire 40% of the exploration and production rights from GDF Suez Qatar under Qatar Petroleums exploration and production sharing agreement for Block 4, an offshore block located north
of Qatar Peninsula. GDF Suez Qatar

Exploration and Production

We engage in crude oil and natural gas exploration, development and production. Substantially all of our total estimated
proved crude oil and natural gas reserves are located in China, principally in northeastern, northern, southwestern and northwestern China. Meanwhile, we have been further extending our overseas cooperation and our strategic layout in five major
overseas oil and gas cooperation regions has been substantially completed. In the year ended December 31, 2012, the crude oil and natural gas produced by us at overseas regions accounted for 12.4% and 5.4% of our total production of crude oil
and natural gas, respectively.

We currently hold exploration and exploitation licenses for oil and gas
(including coal seam gas) covering a total area of approximately 417.5 million acres, consisting of the exploration licenses covering a total area of approximately 394.9 million acres and the exploitation licenses covering a total area of
approximately 22.6 million acres.

To further develop our crude oil and natural gas businesses, we have
obtained oil and gas exploration licenses covering an area of 41.76 million acres in South China Sea. The crude oil and natural gas exploration in that area is currently under way.

The following table sets forth the financial and operating data of our exploration and production segment for each of the
years ended December 31, 2010, 2011 and 2012:

Reserves

Our estimated proved reserves as of December 31, 2012 totaled approximately 11,018.0 million barrels of crude oil and approximately 67,581.2 Bcf of natural gas. As of December 31, 2012,
proved developed reserves for crude oil and natural gas accounted for 67.1% and 46.8% of our total proved crude oil and natural gas reserves, respectively. Total proved hydrocarbon reserves on a BOE basis increased by 0.2% from approximately
22,237.0 million BOE as of December 31, 2011 to approximately 22,281.5 million BOE as of December 31, 2012, taking account of our overseas crude oil reserves of 799.1 million barrels and overseas natural gas reserves of 1,135.1 Bcf,
totaling 988.3 million BOE. Natural gas as a percentage of total proved hydrocarbon reserves increased from 50.0% as of December 31, 2011 to 50.6% as of December 31, 2012.

We prepared our reserve estimates as of December 31, 2010, 2011 and 2012 on the basis of reports prepared by
independent engineering consultants, namely DeGolyer and MacNaughton, Gaffney, Cline & Associates (Consultants) Pte Ltd, Gaffney, Cline & Associates, Inc. and McDaniel & Associates Consultants, Ltd. Our reserve estimates
include only crude oil and natural gas which we believe can be reasonably produced within the current terms of our production licenses or within the terms of the licenses which we are reasonably certain can be renewed. See Regulatory Matters
 Exploration Licenses and Production Licenses for a discussion of our production licenses. Also see Item 3  Key Information  Risk Factors for a discussion of the uncertainty inherent in the estimation of proved
reserves.

Our reserve data for 2010, 2011 and 2012 were prepared in accordance with the SECs final
rules on Modernization of Oil and Gas Reporting, which became effective on January 1, 2010 and for annual reports for accounting periods ending on or after December 31, 2009.

##### Table of Contents

Our proved undeveloped reserves were 9,618.1 million BOE in 2012. The
main changes in our proved undeveloped reserves in 2012 include (i) the conversion of 1,375.9 million BOE of proved undeveloped reserves into proved developed reserves; and (ii) an increase of 1,603.5 million BOE in proved
undeveloped reserves through extensions and discoveries as well as revisions of previous data as a result of improved discoveries. In 2012, we spent RMB164,712 million on developing proved undeveloped reserves. The overwhelming majority of our
proved undeveloped reserves are situated around the oil fields that are currently producing. The majority of our proved undeveloped reserves are already scheduled for development within five years after initial booking.

Some of our natural gas proved undeveloped reserves are being developed more than five years after their initial
disclosure primarily due to the effect of long-term natural gas supply contracts. The sale of natural gas produced from our reserves located in China is subject to our long-term contractual obligations to provide a stable supply of natural gas to
customers. We sell all of the natural gas through our pipelines and under long-term supply arrangements with customers.

There are mainly two types of long-term supply arrangements. The first is multi-years supply contracts with terms ranging from 20 to 30 years that can be extended upon mutual agreement. The second type is
renewable annual contracts. Majority of the natural gas produced from our gas fields in China is put into our nationwide, long-range pipeline system and sold to customers who have entered into multi-years supply contracts with us in the areas where
the long-range pipeline system covers. A small portion of the natural gas produced by our company is put into local or internal pipeline systems and sold to customers in the areas adjacent to the companys gas fields. These customers typically
have formed de-facto long-term relationships with our company over the years and enter into supply contracts with us before the yearend to determine the amount of gas to be purchased for the next year, with such contracts being renewed every year.
In general, our supply relationships with customers under the annual contracts have existed for more than ten years.

Mainly as a result of our contractual obligations to ensure long-term stable supply of natural gas to customers, we must maintain a relatively large amount of proved undeveloped natural gas reserves and
develop them over an extended period of time, and in some cases longer than five years.

The following tables
set forth our crude oil and natural gas proved reserves and proved developed reserves by region as of December 31, 2010, 2011 and 2012.

Exploration and Development

We are currently conducting exploration and development efforts in 12 provinces, two municipalities under the direct administration of the central government and three autonomous regions in China as well
as in certain regions in other countries. We believe that we have more extensive experience in the exploration and development of crude oil and natural gas than any of our principal competitors in China.

The following table sets forth the number of wells we drilled, or in which we participated, and the results thereof, for
the periods indicated.

In 2012, we supplied a substantial majority of our total crude oil sales to our refineries.
We entered into a crude oil mutual supply framework agreement with Sinopec on January 1, 2013 for the supply of crude oil to each others refineries in 2013. Under this agreement, we agreed in principle to supply 4.68 million tons of
crude oil to Sinopec in 2013. For the years ended December 31, 2010, 2011 and 2012, the average lifting costs of our crude oil and natural gas production were US$9.97 per BOE, US$11.23 per BOE and US$11.74 per BOE, respectively.

Principal Oil and Gas Regions

Daqing Oil Region

The Daqing oil region, our
largest oil and gas producing property, is located in the Songliao basin and covers an area of approximately one million acres. In 2010, 2011 and 2012, our crude oil production volume in the Daqing oil region was 805.6 thousand barrels per day,
804.4 thousand barrels per day and 799.3 thousand barrels per day, respectively. As of December 31, 2012, we produced crude oil from 37 fields in the Daqing oil region.

##### Table of Contents

As of December 31, 2012, our proved crude oil reserves in the Daqing
oil region were 2,697.1 million barrels, representing 24.5% of our total proved crude oil reserves. As of December 31, 2010 and 2011, the proved crude oil reserves in our Daqing oil region were 3,178.1 million barrels and
2,925.2 million barrels, respectively. In 2012, the crude oil reserve-to-production ratio of the Daqing oil region was 9.1 years.

Daqings crude oil has a low sulfur and high paraffin content. As many refineries in China, particularly those in northeastern China, are configured to refine Daqing crude oil, we have a stable
market for the crude oil we produce in the Daqing oil region.

Xinjiang Oil Region

The Xinjiang oil region is one of our four largest crude oil producing properties and is located in the Junggar basin in

|(1) | Represents the primary distillation capacity of crude oil and condensate.
|--- | -------------------------------------------------------------------------

In each of the years ended December 31, 2010, 2011 and 2012, the average utilization rate of the primary
distillation capacity at our refineries was 91.3%, 92.0% and 90.1%, respectively, and the average yield for our four principal refined products (gasoline, kerosene, diesel and lubricants) at our refineries was 66.3%, 66.6% and 67.8%, respectively.
Yield represents the number of tons of a refined product expressed as a percentage of the number of tons of crude oil from which that product is processed. In each of the years ended December 31, 2010, 2011 and 2012, the yield for
all refined products at our refineries was 93.5%, 94.0% and 93.8%, respectively.

Dalian Petrochemical,
Lanzhou Petrochemical, Dushanzi Petrochemical, Jilin Petrochemical, Fushun Petrochemical and Guangxi Petrochemical were our leading refineries in terms of both primary distillation capacity and refining throughput in 2012.

To maintain effective operations of our facilities and lower production costs, we have endeavored to achieve the most
cost-efficient proportions of various types of crude oil in our refining process. We purchase a portion of our crude oil requirements from third-party international suppliers located in different countries and regions. As a result, in 2012, we
purchased a small amount of crude oil, through independent suppliers, from certain countries on the U.S. sanction list, such as Sudan. The crude oil so purchased was mingled with crude oil from other sources during the refining process.

Chemicals

Most of our chemical plants are near to our refineries and are also connected with the refineries by pipelines, providing
additional production flexibility and opportunities for cost competitiveness. Our exploration and production and natural gas and pipeline operations supply substantially all of the hydrocarbon feedstock requirements for our chemicals operations.

We are one of the major producers of ethylene in China. We use the bulk of the ethylene
we produce as a principal feedstock for the production of many chemical products, such as polyethylene. As of December 31, 2012, our annual ethylene production capacity was 5,110 thousand tons. Our production volume of ethylene increased
by 6.4 % from 3,467 thousand tons in 2011 to 3,690 thousand tons in 2012. The ethylene projects at Fushun Petrochemical and Daqing Petrochemical were completed and put into operation in the fourth quarter of 2012.

We produce a number of synthetic resin products, including polyethylene, polypropylene and ABS. As of December 31,
2012, our production capacities for polyethylene, polypropylene and ABS were 4,462 thousand tons, 3,749 thousand tons and 495 thousand tons, respectively. Currently, there is a large domestic demand for polyolefin and ABS. We intend
to increase the production, and improve the quality, of these products. We are building new production facilities with new technology for the production of these products in Sichuan Petrochemical, Jilin Petrochemical and other branch companies to
meet this target.

Marketing of Chemicals

Our chemical products are distributed to a number of industries that manufacture components used in a wide range of
applications, including automotive, construction, electronics, medical manufacturing, printing, electrical appliances, household products, insulation, packaging, paper, textile, paint, footwear, agriculture and furniture industries.

Our Principal Markets for Natural Gas

In 2012, in addition
to satisfying the demand of the northwestern, central and northeastern regions of China, we sold our natural gas mainly to the northern, eastern and southeastern regions of the PRC.

Sichuan Province and Chongqing Municipality are two of our principal markets for natural gas in southwest China. We
supply natural gas to Sichuan Province and Chongqing Municipality from our exploration and production operations in the Sichuan oil and gas region. Beijing Municipality, Tianjin Municipality, Hebei Province and Shandong Province in northern China
have a relatively high energy consumption levels. These areas are important markets for our natural gas transmission and marketing business. We supply natural gas to these areas primarily from the Changqing oil region through the Shaanxi to Beijing
natural gas pipeline.

Shanghai Municipality, Jiangsu Province, Zhejiang Province and Anhui Province located
in Yangtze River Delta of eastern China, and Henan Province and Hubei Province located in the central China have become our significant natural gas markets.

We have entered into contracts to provide approximately 3,777 Bcf of natural gas to certain users in 2013. However, the committed quantity of supply may be adjusted by us and the users in the course of
the performance of the contracts in light of the actual situation.

Each year, we must supply natural gas to
customers subject to the government-formulated guidance supply plan first as required by the PRC government. We enter into natural gas supply contracts with those customers on the basis of the amount of natural gas to be supplied according to the
guidance supply plan for the following years supply.

Driven by environmental and efficiency concerns,
the PRC government is increasingly encouraging industrial and residential use of natural gas to meet primary energy and environmental protection needs. The PRC government has adopted a number of laws and regulations to require municipal governments
to increase the use of clean energy, such as natural gas and liquefied petroleum gas, to replace the use of raw coal. Several local governments, including that of Beijing, have adopted policies to facilitate an increase in natural gas consumption in
order to reduce the air pollution level. The PRC government has also adopted a preferential value-added tax rate of 13% for natural gas production as compared to a 17% value-added tax rate for crude oil production.

##### Table of Contents

We believe that these policies have had a positive effect on the development
and consumption of natural gas in many municipalities that are our existing or potential markets for natural gas. We believe that these favorable policies will continue to benefit our natural gas business.

Natural Gas Transmission Infrastructure

As of December 31, 2012, we owned and operated approximately 40,995 kilometers of natural gas pipelines in China. Our natural gas pipelines represent the vast majority of Chinas onshore natural
gas pipelines. Our existing natural gas pipelines form a national trunk network for natural gas supply and the regional natural gas supply networks in northwestern, southwestern, northern and central China as well as the Yangtze River Delta.

The First West-East Gas Pipeline

The construction of the First West-East Gas Pipeline commenced officially in July 2002 and was entirely completed and put into operation on October 1, 2004. The main line of our West-East Gas
Pipeline links our natural gas fields in Xinjiang and Changqing with Henan Province, Anhui Province, Jiangsu Province, Shanghai Municipality and other areas in the Yangtze River Delta. It is designed to mainly transmit the natural gas produced at
Tarim oil region to Henan, Anhui, Jiangsu, Zhejiang and Shanghai. The First West-East Gas Pipeline includes one main line, three branch lines and two underground storage facilities, with a total length of 6,426 kilometers, of which the main
line has a total length of 3,843.5 kilometers. The First West-East Gas Pipeline has a designed annual throughput capacity of 600.4 Bcf.

The Second West-East Gas Pipeline

In February 2008, we commenced the construction of the Second West-East Gas Pipeline. The west section of the Second West-East Gas Pipeline was put into operation in December 2009. In June 2011, the
east section was put into operation. By the end of 2012, the main line and branch lines as well as the Hong Kong branch line of the Second West-East Gas Pipeline were all completed and put into operation. The Second West-East Gas Pipeline includes
one main line, eight branch lines and three underground storage facilities, with a total length of 8,704 kilometers. The main line of the Second West-East Gas Pipeline has a length of 4,978 kilometers. The western section of the main line extends
from Horgos to Zhongwei with a length of 2,461 kilometers and a designed annual throughput capacity of 1,059.5 Bcf. The eastern section of the main line extends from Zhongwei to Guangzhou with a length of 2,517 kilometers and a designed annual
throughput capacity of 988.8 Bcf.

In addition, we also operate other natural gas pipelines, such as the Zhong
County-to-Wuhan natural gas pipeline, the first, the second and the third Shaanxi-to-Beijing natural gas pipelines and Sebei-to-Lanzhou natural gas pipelines.

Crude Oil Transportation and Storage Infrastructure

We
have an extensive network for the transportation, storage and distribution of crude oil, which covers many regions of China.

As of December 31, 2012, our crude oil transportation and storage infrastructure consisted of:



| |  |  | 16,344 kilometers of crude oil pipelines; and
| | - |  | ---------------------------------------------



| |  |  | crude oil storage facilities with an aggregate storage capacity of approximately 35.6 million cubic meters.
| | - |  | -----------------------------------------------------------------------------------------------------------

Russia to China Crude Oil Pipeline

In May 2009, we commenced the construction of the Russia to China crude oil transmission pipeline (the Mohe-to-Daqing section) upon the approval of the National Development and Reform Commission, or NDRC.

##### Table of Contents

We are the constructor and operator of the section crossing the Heilongjiang River and the section lies in China. This pipeline extends from the Skovorodino off-take station of Russias Far
East Pipeline, through Galinda at the Russian border, Heilongjiang Province and Inner Mongolia, to Daqing terminal station. With a designed transmission capacity of 15 million tons, this pipeline is 935 kilometers long. This pipeline was
entirely completed on September 27, 2010 and was put into commercial operation on January 1, 2011.

In addition, we also operate other crude oil pipelines, including the crude oil pipeline network for western regions and
the crude oil pipeline network for northeastern regions.

Refined Product Transportation and Storage Infrastructure

As of December 31, 2012, our refined product transportation and storage infrastructure includes:



| |  |  | 9,437 kilometers of refined product pipelines; and
| | - |  | --------------------------------------------------



| |  |  | refined product storage facilities with a total storage capacity of approximately 32.4 million cubic meters.
| | - |  | ------------------------------------------------------------------------------------------------------------

The Lanzhou-to-Zhengzhou-to-Changsha Pipeline

We received the approval from the NDRC for and commenced the construction of the Lanzhou-to-Zhengzhou-to-Changsha refined oil pipeline in December 2007. The pipeline starts from Lanzhou of Gansu Province
and terminates at Changsha of Hunan Province, with a total length of 3,111 kilometers, including the length of all the main lines and branch lines. We finished the construction and commenced the operation of the section from Lanzhou to Zhengzhou in
April 2009 and the section from Zhengzhou to Wuhan in August 2009. We expect to finish the construction of all the main line and branch lines by May 2013.

In addition, we also operate other refined product pipelines, such as the refined product pipelines for western regions and Lanzhou-to-Chengdu-to-Chongqing refined product pipeline.

During the past three years, we have not experienced any delays in delivering natural gas, crude oil and refined products
due to pipeline capacity constraints.

Competition

As an oil and gas company operating in a competitive industry, we compete in each of our business segments in both China
and international markets for desirable business prospects and for customers. Our principal competitors in China are China Petroleum and Chemical Corporation, or Sinopec, including its subsidiary China National Star Petroleum Corporation, or CNSPC,
and CNOOC.

Exploration and Production Operations

We are the largest onshore oil and gas company in China in terms of proved crude oil and natural gas reserves as well as
crude oil and natural gas production and sales. However, we compete with other domestic oil and gas companies for the acquisition of desirable crude oil and natural gas prospects. Similarly, we face some competition in the development of offshore
oil and gas resources. We believe that our experience in crude oil and natural gas exploration and production and our advanced exploration and development technologies that are suitable for diverse geological conditions in China will enable us to
maintain our dominant position in discovering and developing crude oil and natural gas reserves in China.

Refining and Chemicals
Operations and Marketing Operations

We compete with Sinopec in our refining and chemicals operations and
marketing operations on the basis of price, quality and customer service. Most of our refineries and chemical plants are located in the northeastern and

##### Table of Contents

northwestern regions of China where we have the dominant market share for refined products and chemical products. We sell the remainder of our refined products and chemical products to the
eastern, southern, southwestern and central-southern regions of China, where our products have a considerable market share. The eastern and southern regions of China, where refined products and chemical products are in higher demand, are important
markets for our refined products and chemical products. Sinopec has a strong presence in the eastern and southern regions of China in competition with us, and most of Sinopecs refineries, chemical plants and distribution networks are located
in these regions in close proximity to these markets. Moreover, as the newly constructed facilities of CNOOC commenced operation in the same region, large quantity of chemical products have been marketed into that area. As a result, the competition
has further intensified. We expect that we will continue to face competition from other competitors in our refined products and chemical products sales in these regions. See Item 3  Key Information  Risk Factors.

We also face competition from imported refined products and chemical products on the basis of price and quality. As a
result of Chinas entry into the WTO, competition from foreign producers of refined products and chemical products has increased and the retail and wholesale markets in China for refined products and chemical products will be gradually opened
to foreign competition as tariff and non-tariff barriers for imported refined products and chemical products are being lifted over time. For example, sales of chemical products imported from the Middle East have increased rapidly in China in recent
years. We will face more and more challenges in the competition of refined and chemical products. All these force us to reduce our production costs, improve the quality of our products and optimize our product mix. See Item 3  Key
Information  Risk Factors.

Natural Gas and Pipeline Operations

We are the largest natural gas supplier in the PRC in terms of the sales volume. Currently, we face competition with
Sinopec, CNOOC and coal-based natural gas producers in the supply of natural gas in Beijing Municipality, Tianjin Municipality, Hebei Province, Shanghai Municipality, Jiangsu Province, Anhui Province, Henan Province, Hubei Province, Hunan Province
and the northwestern regions of China, our existing principal markets for natural gas. Currently, Sinopec has natural gas fields in Sichuan Province and Chongqing Municipality and sells natural gas to users in places such as Sichuan, Chongqing,
Hunan, Jiangsu, Zhejiang and Shanghai. Further, we intend to expand our markets for natural gas into the coastal regions in southeastern China where we may face competition from CNOOC and Sinopec. We believe that our dominant natural gas resources
base, our relatively advanced technologies and skills in managing long distance pipelines will enable us to continue to be a dominant player in the natural gas markets in China.

Environmental Matters

Together with other companies in the industries in which we operate, we are subject to numerous national, regional and
local environmental laws and regulations and environmental regulations promulgated by the governments in whose jurisdictions we have operations. These laws and regulations concern our oil and gas exploration and production operations, petroleum and
petrochemical products and other activities. In particular, some of these laws and regulations:



| |  |  | require an environmental evaluation report to be submitted and approved prior to the commencement of exploration, production, refining and chemical
projects;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | restrict the type, quantities, and concentration of various substances that can be released into the environment in connection with drilling and

These laws and regulations may also restrict air emissions and discharges to
surface and subsurface water resulting from the operation of natural gas processing plants, chemical plants, refineries, pipeline systems and other facilities that we own. In addition, our operations are subject to laws and regulations relating to
the generation, handling, storage, transportation, disposal and treatment of solid waste materials.

We
anticipate that the environmental laws and regulations to which we are subject will become increasingly strict and are therefore likely to have an increasing impact on our operations. It is difficult, however, to predict accurately the effect of
future developments in such laws and regulations on our future earnings and operations. Some risk of environmental costs and liabilities is inherent in certain of our operations and products, as it is with other companies engaged in similar
businesses. We cannot assure you that material costs and liabilities will not be incurred. However, we do not currently expect any material adverse effect on our financial condition or results of operations as a result of compliance with such laws
and regulations. We paid pollutant discharge fees of approximately RMB305 million, RMB324 million and RMB327 million in 2010, 2011 and 2012, respectively.

To meet future environmental obligations, we are engaged in a continuous program to develop effective environmental protection measures. This program includes research on:



| |  |  | building environment-friendly projects;
| | - |  | ---------------------------------------



| |  |  | reducing sulphur levels in gasoline and diesel fuel;
| | - |  | ----------------------------------------------------



| |  |  | reducing paraffin and benzene content in gasoline, and continuously reducing the quantity of emissions and effluents from our refineries and
petrochemical plants; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | developing and installing monitoring systems at our pollutant discharge openings and developing environmental impact assessments for construction
projects.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------

Our capital expenditures on environmental programs in 2010, 2011 and 2012 were
approximately RMB1.28 billion, RMB1.65 billion and RMB1.94 billion, respectively.

Because a number of
our production facilities are located in populated areas, we have established a series of preventative measures to improve the safety of our employees and surrounding residents and minimize disruptions or other adverse effects on our business. These
measures include:



| |  |  | providing each household in areas surrounding our production facilities with printed materials to explain and illustrate safety and protection
knowledge and skills; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | enhancing the implementation of various effective safety production measures we have adopted previously.
| | - |  | --------------------------------------------------------------------------------------------------------

We believe that these preventative measures have helped reduce the possibility of incidents that may result in serious
casualties and environmental consequences. In addition, the adoption of these preventative measures has not required significant capital expenditures to date, and therefore, will not have a material adverse effect on our results of operations and
financial condition.

Legal Proceedings

We are involved in several legal proceedings concerning matters arising in the ordinary course of our business. We
believe, based on currently available information, that these proceedings, individually or in the aggregate, will not have a material adverse effect on our results of operations or financial condition.

Properties

Under a restructuring agreement we entered into with CNPC on March 10, 2000, CNPC undertook to us the following:



| |  |  | CNPC would use its best endeavors to obtain formal land use right licenses to replace the entitlement certificates in relation to the 28,649 parcels
of land, which were leased or transferred to us from CNPC, within one year from August, September and October 1999 when the relevant entitlement certificates were issued;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | CNPC would complete, within one year from November 5, 1999, the necessary governmental procedures for the requisition of the collectively owned
land on which 116 service stations owned by us are located; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | CNPC would obtain individual building ownership certificates in our name for all of the 57,482 buildings transferred to us by CNPC, before
November 5, 2000.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------

As of December 31, 2012, CNPC obtained formal land use right
certificates for 28,223 of the 28,649 parcels of land and ownership certificates for some buildings. The governmental procedures for the above-mentioned service stations located on collectively owned land have not been completed to date. We
believe that the use of and the conduct of relevant activities at the above-mentioned parcels of land, service stations and buildings are not affected by the fact that the relevant land use right certificates or building ownership certificates have
not been obtained or the fact that the relevant governmental procedures have not been completed. We believe that this will not have any material adverse effect on our results of operations and financial condition.

We hold exploration and production licenses covering all of our interests in developed and undeveloped acreage, oil and
natural gas wells and relevant facilities.

Exploration Licenses and Production Licenses

The Mineral Resources Law authorizes the Ministry of Land and Resources to exercise administrative authority over the exploration and production of mineral resources within the PRC. The Mineral Resources
Law and its supplementary regulations provide the basic legal framework under which exploration licenses and production licenses are granted. The Ministry of Land and Resources has the authority to issue exploration licenses and production licenses.
Applicants must be companies approved by the State Council to engage in oil and gas exploration and production activities.

Applicants for exploration licenses must first register with the Ministry of Land and Resources blocks in which they intend to engage in exploration activities. The holder of an exploration license is
obligated to make a progressively increasing annual minimum exploration investment relating to the exploration blocks in respect of which the license is issued. Investments range from RMB2,000 per square kilometer for the initial year to RMB5,000
per square kilometer for the second year, and to RMB10,000 per square kilometer for the third and subsequent years. Additionally, the holder has to pay an annual exploration license fee that starts at RMB100 per square kilometer for each of the
first three years and increases by an additional RMB100 per square kilometer per year for subsequent years up to a maximum of RMB500 per square kilometer. The maximum term of an oil and natural gas exploration license is seven years, subject to
renewal upon expiration of the original term, with each renewal being up to two years. At the exploration stage, an applicant can also apply for a progressive exploration and production license that allows the holder to test and develop reserves not
yet fully proven. Upon the detection and confirmation of the quantity of reserves in a certain block, the holder must apply for a production license based on economic evaluation, market conditions and development planning in order to shift into the
production phase in a timely fashion. In addition, the holder needs to obtain the right to use that block of land. Generally, the holder of a full production license must obtain a land use rights certificate for industrial land use covering that
block of land.

The Ministry of Land and Resources issues production licenses to applicants on the basis of
the reserve reports approved by the relevant authorities. Production license holders are required to pay an annual production right usage fee of RMB1,000 per square kilometer. Administrative rules issued by the State Council provide that



42

##### Table of Contents

the maximum term of a production license is 30 years. In accordance with a special approval from the State Council, the Ministry of Land and Resources has issued production licenses with terms
coextensive with the projected productive life of the assessed proven reserves as discussed above. Each of our production licenses is renewable upon our application 30 days prior to expiration. If oil and gas prices increase, the productive life of
our crude oil and natural gas reservoirs may be extended beyond the current terms of the relevant production licenses.

Among the major PRC oil and gas companies, the exploration licenses and production licenses held by PetroChina, Sinopec and CNOOC account for the majority of mining rights in China. Among those companies,
PetroChina and Sinopec primarily engage in onshore exploration and production, while CNOOC primarily engages in offshore exploration and production.

Pricing

Crude Oil

PetroChina and Sinopec set their crude oil median prices each month based on the average Singapore market FOB prices for
crude oil of different grades in the previous month. In addition, PetroChina and Sinopec negotiate a premium or discount to reflect transportation costs, the differences in oil quality and market supply and demand. The National Development and
Reform Commission will mediate if PetroChina and Sinopec cannot agree on the amount of premium or discount.

Refined
Products

Since October 2001, PetroChina has set its retail prices within an 8% floating range of the
published retail median guidance prices of gasoline and diesel published by the National Development and Reform Commission (but after March 26, 2006, the price of diesel for fishing vessels has been set in line with the published retail base
price, with no upward adjustment for the time being). These retail median guidance prices of gasoline and diesel vary in each provincial level distribution region. From October 2001 to early 2006, the National Development and Reform Commission
published the retail median guidance prices of gasoline and diesel from time to time based on the weighted average FOB Singapore, Rotterdam and New York trading prices for diesel and gasoline plus transportation costs and taxes. Generally,
adjustments were made only if the weighted average prices fluctuate beyond 8% of the previously published retail median guidance price. In 2006, the PRC government, under its macro economic controls, introduced a mechanism for determining the prices
of refined products.

On December 18, 2008, the PRC government further improved the pricing mechanism and
the domestic prices of refined oil products continue to be indirectly linked to the international market. Under the improved mechanism, the domestic ex-factory price of the refined oil products are determined on the basis of the corresponding
international crude oil prices and by taking consideration of the average domestic processing cost, tax and appropriate profit margin. The prices of diesel and gasoline continue to follow the government set prices and the government guiding prices.
The retail prices of gasoline and diesel are subject to highest retail prices set by the government. The highest retail price is determined on the basis of the ex-factory price and the profit margin for retailing activities.

On May 7, 2009, the National Development and Reform Commission promulgated and implemented the Measures for
Administration of Petroleum Price (on trial) (the Oil Price Measures). The Oil Price Measures officially specifies the relevant conditions and mechanisms for the adjustment of the prices of Chinas domestic refined oil products.
Under the Oil Price Measures, when the change in the average price of crude oil on the international market for 22 consecutive days exceeds 4%, prices of domestic refined oil products may be adjusted accordingly. When the price of crude oil on the
international market becomes lower than US$80 per barrel, the prices of domestic refined oil products shall be computed on the basis of normal profit margin for processing. On the contrary, when the price of crude oil on the international market
becomes higher than US$80 per barrel, the profit margin for processing shall be reduced until being reduced to zero. When the price of crude oil becomes



43

##### Table of Contents

higher than US$130 per barrel, appropriate financial and tax policies shall be adopted to ensure the production and supply of refined oil products and the stability of the domestic gasoline and
diesel prices. Retailers of refined oil products may set the retail prices freely as long as their retail prices are not higher than the highest retail prices of gasoline and diesel set by the government.

On March 26, 2013, the National Development and Reform Commission, or the NDRC, promulgated the refined oil products
pricing mechanism enhancement system. This is Chinas second oil pricing reform after its first refined oil products price, tax and fee reform commenced on December 16, 2008. Under this new system, (i) the price adjustment period was
shortened from 22 working days to 10 and the 4% limit on the price adjustment range was eliminated; (ii) the composition of the basket of crudes to which refined oil products prices are linked will be adjusted accordingly in light of the
composition of the imported crudes and changes in crudes trading on the international market; and (iii) the refined oil products pricing mechanism will be further enhanced.

Chemical Products

PetroChina determines the prices of all of its chemical products based on market conditions.

Natural Gas

The citygate price of natural gas has
two components: ex-factory price and pipeline transportation tariff.

Prior to December 26, 2005,
ex-factory prices varied depending on whether or not the natural gas sold was within the government-formulated natural gas supply plan. For natural gas sold within the government-formulated supply plan, the National Development and Reform Commission
fixed ex-factory prices according to the nature of the customers. Most of these customers were fertilizer producers. For natural gas sold to customers not subject to the government-formulated supply plan, the National Development and Reform
Commission published median guidance ex-factory prices, and allowed natural gas producers to adjust prices upward or downward by up to 10%.

On December 26, 2005, the NDRC reformed the mechanism for setting the ex-factory prices of domestic natural gas by changing the ex-factory prices to governmental guidance prices, and categorizing
domestic natural gas into two categories. On the basis of the ex-factory price set by the government, subject to the negotiations between the seller and the buyer, the actual ex-factory price of the first category may float upward or downward up to
10%; while the actual ex-factory price of the second category may float upward up to 10% and downward to any level. The price of the first category will be adjusted to the same level as the second category within three to five years. The National
Development and Reform Commission does not allow PetroChina and Sinopec to charge different prices towards internal and external enterprises. On November 10, 2007, the National Development and Reform Commission increased the ex-factory price of
the industrial use natural gas by RMB400/thousand cubic meters. On June 1, 2010, the NDRC raised the median ex-factory prices of the domestic onshore natural gas and as a result of that, the median ex-factory price of all the oil and gas fields
in China increased by RMB0.23/cubic meter. At the same time, the National Development and Reform Commission combined the first category and the second category median ex-factory prices of the natural gas from Dagang Oil Field, Liaohe Oil Field and
Zhongyuan Oil Field, thus ending the dual-track natural gas pricing system as described above. In addition, the National Development and Reform Commission expanded the floating range of the median ex-factory price by allowing the median
ex-factory price to float upward to 10% and downward to any level.

PetroChina negotiates the actual
ex-factory price with natural gas users within the benchmark price and the adjustment range set by the government.

On December 26, 2011, the NDRC implemented a natural gas price formation mechanism pilot reform in Guangdong Province and Guangxi Zhuang Autonomous Region. In general, the approaches under this
reform consist of (i) modifying the natural gas pricing method from the current cost plus pricing to the netback pricing



44

##### Table of Contents

by choosing a pricing reference point and an alternative energy to establish a price linkage mechanism between the natural gas and the alternative energy; (ii) determining the gate station
natural gas price in each province (region or municipality) based on the natural gas price of the pricing reference point and by taking into account the direction of the main flows of the natural gas market resources and the pipeline transportation
cost of natural gas; (iii) implementing a dynamic adjustment mechanism for the gate station natural gas price under which the gate station natural gas price will be initially adjusted on an annual basis and subsequently on a semi-annual or
quarterly basis in response to the change in the price of the alternative energy; and (iv) lifting the control over the ex-works prices of non-conventional natural gas such as the shale gas, coal seam gas and coal gas to allow them to be formed
through market competition.

In the fourth quarter of 2012, in order to secure a stable supply on the local
natural gas market, Sichuan Province and Chongqing Municipality implemented a natural gas pricing mechanism reform and adjusted their local natural gas supply price by referring to the reform model in Guangdong Province and Guangxi Province. After
such adjustment, the natural gas citygate price in Sichuan and Chongqing increased by RMB0.18/cubic meter on average.

The National Development and Reform Commission sets the pipeline transportation tariff for the natural gas transported by pipelines constructed prior to 1991. For natural gas transported by pipelines
constructed after 1991, PetroChina submits to the National Development and Reform Commission for examination and approval proposed pipeline transmission tariffs based on the capital investment made in the pipeline, the depreciation period for the
pipeline, the ability of end users to pay and PetroChinas profit margin.

On April 25, 2010, the
National Development and Reform Commission adjusted the originally government-set flat pipeline transportation tariff for the natural gas transported by pipelines. As a result of such adjustment, our average pipeline transportation tariff for the
natural gas transported by pipelines increased from RMB0.06 per cubic meter to RMB0.14 per cubic meter.

Production and Marketing

Crude Oil

Each year, the National Development and Reform Commission publishes the projected target for the production and process of crude oil in China based on the domestic consumption estimates submitted by
domestic producers, including but not limited to PetroChina, Sinopec and CNOOC, the production of these companies as well as the forecast of international crude oil prices. The actual production levels are determined by the producers themselves and
may vary from the submitted estimates. Since January 1, 2007, when the Measures on the Administration of the Refined Products Market promulgated by the Ministry of Commerce became effective, qualified domestic producers are permitted to engage
in the sale and storage of crude oil. Foreign companies with required qualifications are also allowed to establish and invest in enterprises to conduct crude oil business.

Refined Products

Previously, only PetroChina,
Sinopec and joint ventures established by the two companies had the right to conduct gasoline and diesel wholesale business. Other companies, including foreign invested companies, were not allowed to engage in wholesale of gasoline and diesel in
Chinas domestic market. In general, only domestic companies, including Sino-foreign joint venture companies, were permitted to engage in retail of gasoline and diesel. Since December 11, 2004, wholly foreign-owned enterprises are
permitted to conduct refined oil retail business. Since January 1, 2007, when the Measures on the Administration of the Refined Products Market became effective, all entities meeting certain requirements are allowed to submit applications to
the Ministry of Commerce to conduct refined oil products wholesale, retail and storage businesses.

##### Table of Contents

Natural Gas

The NDRC determines each year the annual national natural gas production target based on the natural gas production
targets submitted by domestic natural gas producers including PetroChina. Domestic natural gas producers determine their annual natural gas production targets on the basis of consumption estimates. The actual production volume of each producer is
determined by the producer itself, which may deviate from the production target submitted by it. The NDRC also formulates the annual natural gas guidance supply plan, which requires natural gas producers to distribute a specified amount of natural
gas to designated key municipalities and key enterprises.

Foreign Investments

Cooperation in Exploration and Production with Foreign Companies

Currently, CNPC is one of the few Chinese companies that have the right to cooperate with foreign companies in onshore
crude oil and natural gas exploration and production in China. CNOOC has the right to cooperate with foreign companies in offshore crude oil and natural gas exploration and production in China.

Sino-foreign cooperation projects and foreign parties in onshore oil and gas exploration and production in China are
generally selected through open bids and bilateral negotiations. Those projects are generally conducted through production sharing contracts. The Ministry of Commerce must approve those contracts.

As authorized by the Regulations of the PRC on Exploration of Onshore Petroleum Resources in Cooperation with Foreign
Enterprises, CNPC has the right to enter into joint cooperation arrangements with foreign oil and gas companies for onshore crude oil and natural gas exploration and production. PetroChina does not have the capacity to enter into production sharing
contracts directly with foreign oil and gas companies under existing PRC law. Accordingly, CNPC will continue to enter into production sharing contracts. After signing a production sharing contract, CNPC will, subject to approval of the Ministry of
Commerce, assign to PetroChina most of its commercial and operational rights and obligations under the production sharing contract as required by the Non-competition Agreement between CNPC and PetroChina.

Transportation and Refining

Since December 1, 2007, PRC regulations encourage foreign investment in the construction and operation of oil and gas pipelines and storage facilities but restrict foreign investment in refineries
with an annual capacity of ten million tons or lower. Furthermore, when appropriate, projects must receive necessary approvals from relevant PRC government agencies. See Item 3  Key Information  Risk Factors.

Import and Export

Since January 1, 2002, state-owned trading companies have been allowed to import crude oil under an automatic licensing system. Non-state-owned trading companies have been allowed to import crude oil
and refine products subject to quotas. The export of crude oil and refined oil products by both state-owned trading companies and non-state-owned trading companies is subject to quota control. The Ministry of Commerce has granted PetroChina the
right to conduct crude oil and refined product import and export business.

Capital Investment and Financing

Capital investments in exploration and production of crude oil and natural gas made by Chinese oil and gas companies are
subject to approval by or filing with relevant government authorities. The following projects are subject to approval by the National Development and Reform Commission:

(1) new oil field development projects with an annual capacity of one million tons or above and new gas field development
projects with an annual capacity of two billion cubic meters or above;

##### Table of Contents

(2) facilities for taking delivery of, storing or transporting imported
liquefied natural gas, and cross-province (region or municipality) major oil transmission pipeline facilities;

(3) cross-province (region or municipality) gas transmission facilities, or gas transmission facilities with an annual
capacity of 500 million cubic meters or above;

(4) new refineries, first expansion of existing
refineries, new ethylene projects, and transformation or expansion of existing ethylene projects which will result in an additional annual capacity of 200 thousand tons;

(5) new Purified Terephthalic Acid (PTA), P-Xylene (PX), diphenylmethane diisocyanate (MDI) and toluene diisocyanate (TDI)
projects, and transformation of existing PTA and PX projects which will result in an additional capacity of 100 thousand tons;

(6) potassium mineral fertilizer projects with an annual capacity of 500 thousand tons or more; and

(7) national crude oil reserve facilities.

Taxation, Fees and Royalty

PetroChina is subject to a variety of taxation, fees and royalty. The table below sets forth the major taxation, fees and
royalty fee payable by PetroChina or by Sino-foreign oil and gas exploration and development cooperative projects. PetroChinas subsidiaries which have the legal person status should report and pay enterprise income tax to the relevant tax
authorities based on the applicable laws and regulations.

and the State Administration of Taxation promulgated the Plan for Implementation of the Pilot Reform for Collection of Value-added Tax in Lieu of Business Tax which sets forth the guidelines, principles and major contents of the pilot reform.
Pursuant to the Plan, effective from January 1 and September 1, 2012, respectively, in pilot provinces and municipalities including Shanghai and Beijing, a pilot reform would be implemented on a step-by-step basis or completed to collect value-added
tax in lieu of business tax on the revenue of PRC entities or individuals located in or resident in pilot provinces or municipalities generated from transportation services and certain modern services or of foreign entities or individuals from
providing taxable services to the above PRC entities or individuals. Certain pipeline transmission services of our company have since then been subject to value-added-tax at the rate of 11%.

Certain oil fields, however, may enjoy certain preferential treatment in respect of the resource tax based on the quality of their actual resources, scale
of exploration and production activities, and actual production cost.

Environmental Regulations

We are subject to various PRC national environmental laws and regulations and also environmental regulations promulgated by the local governments in whose jurisdictions we have operations. China has
adopted extensive environmental laws and regulations that affect the operation of the oil and gas industry. There are national and local standards applicable to emissions control, discharges to surface and subsurface water and disposal, and the
generation, handling, storage, transportation, treatment and disposal of solid waste materials.

##### Table of Contents

The environmental regulations require a company, such as us, to register or
file an environmental impact report with the relevant environmental authority for approval before it undertakes any construction of a new production facility or any major expansion or renovation of an existing production facility. The new facility
or the expanded or renovated facility will not be permitted to operate unless the relevant environmental authority has inspected to its satisfaction that environmental equipment that satisfies the environmental protection requirements has been
installed for the facility. A company that wishes to discharge pollutants, whether it is in the form of emission, water or materials, must submit a pollutant discharge declaration statement detailing the amount, type, location and method of
treatment. After reviewing the pollutant discharge declaration, the relevant environmental authority will determine the amount of discharge allowable under the law and will issue a pollutant discharge license for that amount of discharge subject to
the payment of discharge fees. If a company discharges more than is permitted in the pollutant discharge license, the relevant environmental authority can fine the company up to several times the discharge fees payable by the offending company for
its allowable discharge, or require the offending company to close its operation to remedy the problem.

General

You should read the
following discussion together with our consolidated financial statements and their notes included elsewhere in this annual report. Our consolidated financial statements have been prepared in accordance with IFRS.

Overview

We are engaged in a broad range of petroleum and natural gas related activities, including:



| |  |  | the exploration, development, production and sale of crude oil and natural gas;
| | - |  | -------------------------------------------------------------------------------



| |  |  | the refining of crude oil and petroleum products, and the production and marketing of basic petrochemical products, derivative chemical products and
other chemical products;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | marketing of refined oil products and trading; and
| | - |  | --------------------------------------------------



| |  |  | the transmission of natural gas, crude oil and refined oil products as well as the sale of natural gas.
| | - |  | -------------------------------------------------------------------------------------------------------

We are Chinas largest producer of crude oil and natural gas and are one of the largest companies in China in terms
of sales. In 2012, we produced approximately 916.5 million barrels of crude oil and approximately 2,558.8 Bcf of natural gas for sale. Our refineries also processed approximately 1,012.5 million barrels of crude oil in 2012. In 2012, we
had turnover of RMB2,195,296 million and profit attributable to owners of our company of RMB115,326 million.

Factors Affecting Results of
Operations

Our results of operations and the period-to-period comparability of our financial results are
affected by a number of external factors, including changes in the prices, production and sales volume of our principal products and the regulatory environment.

Prices of Principal Products

The fluctuations in
the prices of crude oil, refined products, chemical products and natural gas have a significant impact on our turnover. See Item 4  Information on the Company  Regulatory Matters  Pricing for a more detailed discussion

Production and Sales Volume for Oil and Gas Products

Our results of operations are also affected by production and sales volumes. Our crude oil and natural gas production
volumes depend primarily on the level of the proved developed reserves in the fields in which we have an interest, as well as other factors such as general economic environment and market supply and demand conditions.

Regulatory Environment

Our operating activities are subject to extensive regulations and controls by the PRC government, including the issuance of exploration and production licenses, the imposition of industry-specific taxes
and levies and the implementation of environmental policies and safety standards. Our results of operations will be affected by any future changes of such regulatory environment.

Critical Accounting Policies

The preparation of our
consolidated financial statements requires our management to select and apply significant accounting policies, the application of which may require management to make judgments and estimates that affect the reported amounts of assets and
liabilities, disclosure of contingent assets and liabilities as of the date of our financial statements, and the reported amounts of turnover and expenses during the reporting period. Notwithstanding the presentation of our principal accounting
policies in Note 3 to our consolidated financial statements included elsewhere in this annual report, we have identified the accounting policies below as most critical to our business operations and the understanding of our financial condition and
results of operations presented in accordance with IFRS. Although these estimates are based on our managements best knowledge of current events and actions, actual results ultimately may differ from those estimates.

Accounting for Oil and Gas Exploration and Production Activities

We use the successful efforts method of accounting, with specialized accounting rules that are unique to the oil and gas
industry, for oil and gas exploration and production activities. Under this method, geological and geophysical costs incurred are expensed when incurred. However, all costs for developmental wells, support equipment and facilities, and proved
mineral interests in oil and gas properties are capitalized. Costs of exploratory wells are capitalized as construction in progress pending determination of whether the wells find proved reserves. For exploratory wells located in regions that do not
require substantial capital expenditures before the commencement of production, the evaluation of the economic benefits of the reserves in such wells will be completed within one year following the completion of the exploration drilling. Where such
evaluation indicates that no economic benefits can be obtained, the relevant costs of exploratory wells will be converted to dry hole exploration expenses. The relevant costs will be classified as oil and gas assets and go through impairment review
if the evaluation indicates that economic benefits can be obtained. For wells that found economically viable reserves in areas where a major capital expenditure would be required before production can begin, the related well costs remain capitalized
only if additional drilling is under way or firmly planned. Otherwise the well costs are expensed as dry holes. We have no material costs of unproved properties capitalized in oil and gas properties.

Oil and Gas Reserves

The estimation of the quantities of recoverable oil and gas reserves in oil and gas fields is integral to effective
management of our exploration and production operations. Because of the subjective judgments involved in developing and assessing such information, engineering estimates of the quantities of recoverable oil and gas reserves in oil and gas fields are
inherently imprecise and represent only approximate amounts.

Before estimated oil and gas reserves are
designated as proved, certain engineering criteria must be met in accordance with industry standards and the regulations of the SEC. Proved oil and gas reserves are the estimated quantities of crude oil and natural gas, which, by
analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government
regulation before the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether the estimate is a deterministic estimate or probabilistic estimate. Therefore,
these estimates do not include probable or possible reserves. Our proved reserve estimates are updated annually by independent, qualified and experienced oil and gas reserve engineering firms in the United States, Singapore and Canada. Our oil and
gas reserve engineering department has policies and procedures in place to ensure that these estimates are consistent with these authoritative guidelines. Among other factors as required by authoritative guidelines, this estimation takes into
account recent information about each field, including production and seismic information, estimated recoverable reserves of each well, and oil and gas prices and operating costs as of the date the estimate is made. The price shall be the average
price during the 12-month period before the ending date of the period covered by this report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by
contractual arrangements, excluding escalations based upon future conditions. The costs shall be that prevailing at the end of the period.

Despite the inherent imprecision in these engineering estimates, estimated proved oil and gas reserve quantity has a direct impact on certain amounts reported in the financials statements. In addition to
the capitalization of costs related to oil and gas properties on the balance sheet discussed earlier, estimated proved reserves also impact the calculation of depreciation, depletion and amortization expenses of oil and gas properties. The cost of
oil and gas properties is amortized at the field level on the unit of production method. Unit of production rates are based on the total oil and gas reserves estimated to be recoverable from existing facilities based on the current terms of our
production licenses. Our reserve estimates include only crude oil and natural gas which management believes can be reasonably produced within the current terms of the production licenses that are granted by the Ministry of Land and Resources,
ranging from 30 years to 55 years from the effective date of issuance in March 2000, renewable upon application 30 days prior to expiration. Consequently, the impact of changes in estimated proved reserves is reflected prospectively by amortizing
the remaining book value of the oil and gas property assets over the expected future production. If proved reserve estimates are revised downward, earnings could be affected by higher depreciation expense or an immediate write-down of the
propertys book value had the downward revisions been significant See  Property, Plant and Equipment below. Given our large number of producing properties in our portfolio, and the estimated proved reserves, it is unlikely
that any changes in reserve estimates will have a significant effect on prospective charges for depreciation, depletion and amortization expenses.

In addition, due to the importance of these estimates to better understanding the perceived value and future cash flows of a companys oil and gas operations, we have also provided supplemental
disclosures of proved oil and gas reserve estimates prepared in accordance with authoritative guidelines elsewhere in this annual report.

Property, Plant and Equipment

Where it is probable
that property, plant and equipment, including oil and gas properties, will generate future economic benefits, their costs are initially recorded in the consolidated statement of financial position as assets. Cost represents the purchase price of the
asset and other costs incurred to bring the asset into existing use. Subsequent to their initial recognition, property, plant and equipment are carried at cost less accumulated depreciation, depletion and amortization (including any impairment).

Depreciation, to write off the cost of each asset, other than oil and gas properties, to their residual
values over their estimated useful lives is calculated using the straight-line method.

The company uses the following useful lives for depreciation purposes:



|                        |  |  |            | 
|----------------------- |  |  | ---------- | 
|Buildings and plant     |  |  | 8-40 years | 
|Equipment and machinery |  |  | 4-30 years | 
|Motor vehicles          |  |  | 4-14 years | 
|Other                   |  |  | 5-12 years | 

No depreciation is provided on construction in progress until the assets are completed
and ready for use.

The assets residual values and useful lives are reviewed, and adjusted if
appropriate, at the end of each reporting period.

Property, plant and equipment, including oil and gas
properties, are reviewed for possible impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the carrying amount of a cash generating unit
exceeds the higher of its fair value less costs to sell and its value in use, which is the estimated net present value of future cash flows to be derived from the cash generating unit.

Gains and losses on disposals of property, plant and equipment are determined by reference to their carrying amounts and
are recorded in the consolidated profit or loss.

Interest and other costs on borrowings to finance the
construction of property, plant and equipment are capitalized during the period of time that is required to complete and prepare the asset for its intended use. Costs for repairs and maintenance activities are expensed as incurred except for costs
of components that result in improvements or betterments which are capitalized as part of property, plant and equipment and depreciated over their useful lives.

Provision for Asset Decommissioning

Provision is
recognized for the future decommissioning and restoration of oil and gas properties. The amounts of the provision recognized are the present values of the estimated future expenditures. The estimation of the future expenditures is based on current
local conditions and requirements, including legal requirements, technology, price level, etc. In addition to these factors, the present values of these estimated future expenditures are also impacted by the estimation of the economic lives of oil
and gas properties. Changes in any of these estimates will impact the operating results and the financial position of the company over the remaining economic lives of the oil and gas properties.

Operating Expenses.Operating expenses increased by 10.9% from RMB1,821,382
million for the year ended December 31, 2011 to RMB2,020,777 million for the year ended December 31, 2012, of which:

Purchases, Services and Other.Purchases, services and other increased by 14.9% from RMB1,227,533 million for the year ended December 31, 2011 to RMB1,411,036 million for
the year ended December 31, 2012. This was primarily due to the increase of the purchase costs as a result of the expansion of oil products trading and the increased import of natural gas to meet the increasing domestic demand.

Employee Compensation Costs.Employee compensation costs (including salaries of
548,355 employees and 318,311 temporary employees in 2012 and such additional costs as contributions to social security and housing fund scheme and employee training expenses) of the company were RMB106,189 million for the year ended
December 31, 2012, representing an increase of 9.3% compared with that in 2011 at RMB97,162 million. This was primarily due to the fact that the company has adjusted its front-line employees salaries to appropriate level, taking into
consideration of certain factors, such as the rise of the domestic consumer price index, the increase of our turnover and the expansion of operations and the rise of the social security contribution as a result of changes in local government
policies.

Exploration Expenses.Exploration expenses was RMB23,972 million for the year
ended December 31, 2012, being substantially the same as RMB23,908 million for the year ended December 31, 2011.

Depreciation, Depletion and Amortization. Depreciation,
depletion and amortization increased by 10.1% from RMB138,073 million for the year ended December 31, 2011 to RMB151,975 million for the year ended December 31, 2012. This was primarily due to the fact that both the average carrying value
of fixed assets and the average net value of oil and gas properties increased as a result of an increase in capital expenditure of the company, leading to an increase in depreciation and depletion provisions during 2012.

Selling, General and Administrative Expenses.Selling, general and administrative expenses increased
by 6.8% from RMB69,969 million for the year ended December 31, 2011 to RMB74,692 million for the year ended December 31, 2012. Such increase was primarily due to an increase in leasing costs as a result of business expansion and an
increase in the transportation costs due to the increase in the volume of products transported and the cost of transportation per unit.

Taxes other than Income Taxes. Taxes other than income taxes decreased by 4.3% from RMB266,343 million for the year ended December 31, 2011 to RMB254,921 million for the year ended
December 31, 2012. In particular, crude oil special gain levy decreased from RMB102,458 million for the year ended December 31, 2011 to RMB79,119 million for the year ended December 31, 2012 because the threshold of the crude oil
special gain levy was raised in 2011. Resource tax borne by the company increased from RMB19,784 million for the year ended December 31, 2011 to RMB28,079 million for the year ended December 31, 2012, primarily due to the promulgation of
new resource tax policy by the PRC government.

Other Income, net.Other income, net, of
the company for the year ended December 31, 2012 was RMB2,008 million, representing an increase of 25.0% from the other income, net, of the company in the amount of RMB1,606 million for the year ended December 31, 2011. This was primarily
due to the fact that the refund of value-added tax, or VAT, for imported natural gas was recognized by the company in 2012.

Profit from Operations. The profit from operations of the company for the year ended December 31, 2012 was RMB174,519 million, representing a decrease of 4.4% from RMB182,461 million
for the preceding year.

Net Exchange Gain/Loss. We recorded a net exchange gain of RMB131
million for the year ended December 31, 2012, representing an increase of RMB1,067 million as compared with the net exchange loss of RMB936 million for the year ended December 31, 2011. The realization of the net exchange gain was
primarily because the decline of the exchange rate of US dollars against RMB slowed down in 2012 and the exchange rate of CAD against RMB increased in 2012.

Net Interest Expenses.Net interest expenses increased by RMB7,889 million, from RMB8,212 million for the year ended December 31, 2011 to RMB16,101 million for the year ended
December 31, 2012. The increase in net interest expenses was primarily attributable to an increase in the amount of interest-bearing debts prompted by the need to secure required funding for production, operation and capital investment.

Profit Before Income Tax Expense.Profit before income tax expense decreased by 9.4%
from RMB184,215 million for the year ended December 31, 2011 to RMB166,811 million for the year ended December 31, 2012.

Income Tax Expenses. Income tax expenses decreased by 5.4% from RMB38,256 million for the year ended December 31, 2011 to RMB36,191 million for the year ended December 31,
2012. The decrease was primarily due to a decrease in the taxable income for the year.

Profit for the
year. Profit for the year decreased by 10.5% from RMB145,959 million for the year ended December 31, 2011 to RMB130,620 million for the year ended December 31, 2012.

Profit attributable to non-controlling interests of the company.Profit attributable to non-controlling
interests increased by 17.7% from RMB12,998 million for the year ended December 31, 2011 to RMB15,294 million for the year ended December 31, 2012, due to the increase of net profits of certain subsidiaries of the company.

Profit attributable to owners of the company. Profit
attributable to owners of the company decreased by 13.3% from RMB132,961 million for the year ended December 31, 2011 to RMB115,326 million for the year ended December 31, 2012. Such decrease was primarily due to the combined effect of the
increase of the imported natural gas and the purchase price of the imported natural gas exceeding its sales price and the macro regulation over the domestic refined oil price.

Segment Information

Exploration and Production

Turnover.Turnover increased by 1.9% from RMB774,777 million for the year ended
December 31, 2011 to RMB789,818 million for the year ended December 31, 2012. The increase was primarily due to an increase in the sales volumes of crude oil and natural gas. The average realized crude oil price of the company in 2012 was
US$103.65 per barrel, being substantially the same as US$104.20 per barrel in 2011.

Operating
Expenses.Operating expenses increased by 3.5% from RMB555,238 million for the year ended December 31, 2011 to RMB574,863 million for the year ended December 31, 2012, primarily driven by the increase of expenses associated
with depreciation and amortization of RMB15,770 million as compared with the previous year.

The oil and gas
lifting cost increased by 4.5% from US$11.23 per barrel in 2011 to US$11.74 per barrel in 2012. Excluding the impact of the fluctuation of exchange rates, the oil and gas lifting cost increased by 2.2% compared the previous period.

Profit from Operations.The profit from operations for the year ended December 31, 2012 was RMB214,955
million, representing a decrease of 2.1% from RMB219,539 million for the preceding year. Such decrease was primarily attributable to the increase of depreciation and amortization. The exploration and production segment remains as the most important
profit contributing segment of the company.

Refining and Chemicals

Turnover.Turnover increased by 4.2% from RMB847,711 million for the year ended December 31,
2011 to RMB883,218 million for the year ended December 31, 2012. The increase was primarily due to an increase in both the selling prices and sales volumes of key refined products.

Operating Expenses. Operating expenses increased by 1.9% from RMB909,577 million for the year ended
December 31, 2011 to RMB926,729 million for the year ended December 31, 2012. The operating expenses incurred for purchases, services and other increased by RMB15,751 million as compared with last year. Such increase was primarily due to
an increase in expenses incurred for purchasing crude oil, raw materials and power.

The cash processing cost
of refineries increased by 5.7% from RMB146.27 per ton in 2011 to RMB154.61 per ton in 2012, which was primarily due to an increase in the costs of power and additives.

Profit from Operations. Due to the fact that international crude oil prices remained high in 2011,
the prices of domestic refined products were subject to government regulation and control and the demand in the petrochemical market was down, the refining and chemicals segment recorded operating losses of RMB43,511 million for the year ended
December 31, 2012, of which, the refining operations and the chemicals operations recorded operating losses of RMB33,672 million and RMB9,839 million for the year ended December 31, 2012, respectively. The operating losses of the refining
operations decreased by RMB26,415 million compared to the previous year and the operating losses of the chemical operations increased by RMB8,060 million.

Marketing

Turnover.Turnover increased by 11.7% from RMB1,693,130 million for the year ended December 31,
2011 to RMB1,890,558 million for the year ended December 31, 2012. The increase was primarily due to an increase in turnover from the oil products trading business.

Operating Expenses.Operating expenses increased by 12.1% from RMB1,672,477 million for the year ended
December 31, 2011 to RMB1,874,167 million for the year ended December 31, 2012, primarily due to an increase in the purchase cost relating to the oil products trading business.

Profit from Operations. Profit from operations was RMB16,391 million for 2012, representing a decrease of
20.6% from RMB20,653 million for the year ended December 31, 2011, which was primarily due to the weak demand of oil products in 2012.

Natural Gas and Pipeline

Turnover.Turnover amounted to RMB202,196 million in 2012, representing an increase of 16.8% from RMB173,058 million in 2011. This increase was primarily due to (i) increases in both the sales and transmission volumes as well as sales price of the
natural gas; and (ii) an increase in the turnover generated from the sales of city gas and LPG in 2012 due to an expansion of such business activities.

Operating Expenses.Operating expenses amounted to RMB204,306 million in 2012, representing an increase of 29.7% from RMB157,528 million in 2011. Such increase was primarily due to an
increase of purchase costs of natural gas.

Profit from Operations.The natural gas and pipeline
segment recorded operating losses of RMB2,110 million for the year ended December 31, 2012, representing a decrease of RMB17,640 million from the profit from operations of RMB15,530 million for the previous year, which was primarily due to
an increase in losses of the sales of natural gas and LNG imported from Central Asia. RMB41,900 million of the operating losses in 2012 were attributable to the losses from the sales of the imported natural gas and LNG.

In 2012, our overseas operations further increased their contribution to the company. Turnover of overseas operations
amounted to RMB702,660 million in 2012, or 32.0% of our total turnover. Profit before income tax expense of overseas operations amounted to RMB32,672 million in 2012, or 19.6% of our profit before income tax expense.

The four operating segments of the company are namely exploration and production, refining and chemicals, marketing as
well as natural gas and pipeline. Overseas operations do not constitute a separate operating segment of the company. The financial data of overseas operations are included in the financial data of the respective operating segments mentioned above.

Operating Expenses.Operating expenses increased by 42.6% from RMB1,277,638
million for the year ended December 31, 2010 to RMB1,821,382 million for the year ended December 31, 2011, of which:

Purchases, Services and Other.Purchases, services and other increased by 54.3% from RMB795,525 million for the year ended December 31, 2010 to RMB1,227,533 million for the year
ended December 31, 2011. This was primarily due to (i) an overall increase in purchase cost as a result of larger trading volume in oil products, increased imports of crude oil by the refineries and the sharp rise in crude oil prices on
the international market, and (ii) an increase in the costs of importing extra natural gas from Central Asia and LNG to ensure the safe and stable supply of gas to urban residents, utilities and key industrial users.

Employee Compensation Costs. Employee compensation costs (including employees salaries and
such additional costs as contributions to social security and housing fund scheme) of the company were RMB97,162 million for the year ended December 31, 2011. Excluding the impact due to the expansion of operations and the rise of the
social security contribution base due to changes in government policies, employee compensation costs of the company increased by 9.8% as compared to the year ended December 31, 2010. This was primarily due to the fact that the company has
adjusted its front-line employees salaries to appropriate level, taking into consideration of certain factors, such as the rise of the domestic consumer price index.

Exploration Expenses. Exploration expenses increased by 4.1% from RMB22,963 million for the year ended
December 31, 2010 to RMB23,908 million for the year ended December 31, 2011. This was primarily due to the fact that the company continued to put more efforts into oil and gas exploration to further strengthen its base of oil and gas
resources.

Depreciation, Depletion and Amortization. Depreciation, depletion and
amortization increased by 22.0 % from RMB 113,209 million for the year ended December 31, 2010 to RMB138,073 million for the year ended December 31, 2011. This was primarily due to the fact that (i) both the average
carrying value of fixed assets and the average net value of oil and gas properties increased as a result of an increase in capital expenditure of the company, leading to an increase in depreciation and depletion provisions during 2011; and
(ii) a higher amount of impairment charges were recorded by the company against certain refining equipment during 2011.

Selling, General and Administrative Expenses.Selling,
general and administrative expenses decreased by 5.8% from RMB74,239 million for the year ended December 31, 2010 to RMB69,969 million for the year ended December 31, 2011. Excluding the impact due to the change in the calculation method
in respect of transportation costs, the year-on-year increase was 11.7%, which was primarily due to an increase in repair costs of refining equipment and extra storage and leasing costs as a result of business expansion.

Taxes other than Income Taxes.Taxes other than income taxes increased by 44.6% from
RMB184,209 million for the year ended December 31, 2010 to RMB266,343 million for the year ended December 31, 2011. In particular: (i) crude oil special gain levy increased from RMB52,172 million for the year ended
December 31, 2010 to RMB102,458 million for the year ended December 31, 2011. With effect from November 1, 2011, the threshold of the crude oil special gain levy was raised from US$40 per barrel to US$55 per barrel. However, as
the international crude oil price rose significantly during the reporting period and only November and December in 2011 were affected by the implementation of the policy of imposing a higher threshold of the crude oil special gain levy, there
was a substantial increase in the companys crude oil special gain levy for the year ended December 31, 2011; (ii) consumption tax borne by the company increased from RMB89,670 million for the year ended December 31, 2010 to
RMB98,795 million for the year ended December 31, 2011, which was primarily due to an increase in the sales volume of refined products from refineries during 2011; and (iii) resource tax borne by the company increased from RMB9,796 million
for the year ended December 31, 2010 to RMB19,784 million for the year ended December 31, 2011. The substantial increase in the companys resource tax for the year ended December 31, 2011 as compared with 2010 was primarily due
to the promulgation of new resource tax policy by the PRC government.

Other Income, net.Other income, net, of the company for the year ended December 31, 2011 was RMB1,606 million, representing an increase of RMB5,795 million from the other expenses, net, of the company in the amount of RMB4,189 million for the year ended
December 31, 2010. This was primarily due to the fact that the refund of value-added tax, or VAT, for imported natural gas, including LNG, was recognized by the company in 2011.

Profit from Operations. The profit from operations of the company for the year ended December 31, 2011
was RMB182,461 million, representing a decrease of 2.8% from RMB187,777 million for the year ended December 31, 2010.

Net Exchange Loss. Net exchange loss decreased from RMB1,172 million for the year ended December 31, 2010 to RMB936 million for the year ended December 31, 2011, representing a
decrease of 20.1%. The decrease in net exchange loss was primarily due to the repayment of loans denominated in Canadian dollars at the end of 2010.

Net Interest Expenses.Net interest expenses increased by 89.3% from RMB4,338 million for the year ended December 31, 2010 to RMB8,212 million for the year ended
December 31, 2011. The increase in net interest expenses was primarily due to (i) an increase in our interest-bearing debts in order to ensure the funds required for production, operation and capital investment; and (ii) an increase
in our financial costs as a result of the increase in interest rates in China.

Profit Before Income Tax
Expense.Profit before income tax expense decreased by 2.7% from RMB189,305 million for the year ended December 31, 2010 to RMB184,215 million for the year ended December 31, 2011.

Income Tax Expenses. Income tax expenses decreased by 0.7% from RMB38,513 million for the year ended
December 31, 2010 to RMB38,256 million for the year ended December 31, 2011, which was primarily due to a decrease in the taxable income for the year.

Profit for the year. Profit for the year decreased by 3.2% from RMB150,792 million for the year ended
December 31, 2010 to RMB145,959 million for the year ended December 31, 2011.

Profit attributable to non-controlling interests of the company.As international oil prices in 2011 increased significantly compared with that of last year, certain overseas subsidiaries engaging in upstream operations recorded material increases in profits, which resulted in an increase of the profit
attributable to non-controlling interests by 20.4%, from RMB10,800 million for the year ended December 31, 2010 to RMB 12,998 million for the year ended December 31, 2011.

Profit attributable to owners of the parent company. Due to the effect of government control over
domestic price of refined oil products, the purchase price of imported natural gas being higher than the selling price of the same and a significant increase in taxes and levies, profit attributable to owners of the parent company decreased by 5.0%
from RMB139,992 million for the year ended December 31, 2010 to RMB132,961 million for the year ended December 31, 2011.

Segment Information

Exploration and Production

Turnover.Turnover increased by 42.2% from RMB544,884 million for the year ended
December 31, 2010 to RMB774,777 million for the year ended December 31, 2011. The increase was primarily due to an increase both in the average realized prices and sales volumes of crude oil and natural gas. The average realized crude oil
price of the company was US$104.20 per barrel in 2011, representing an increase of 42.9% from US$72.93 per barrel in 2010.

Operating Expenses.Operating expenses increased by 41.9% from RMB391,181 million for the year ended December 31, 2010 to RMB555,238 million for the year ended December 31,
2011 because: (i) operating expenses incurred for purchases, services and other increased RMB76,299 million as compared with the previous year, primarily due to an increase in the purchase cost of oil import from Russia and Kazakhstan
during 2011; and (ii) taxes other than income taxes increased RMB70,144 million compared with last year, primarily due to a significant increase in the crude oil special gain levies and the resource tax during 2011.

The oil and gas lifting cost increased by 12.6%, or 7.4% excluding the impact of the fluctuation of exchange rates, from
US$9.97 per barrel in 2010 to US$11.23 per barrel in 2011, which shows that the oil and gas lifting cost was brought under effective control.

Profit from Operations. In 2011, the exploration and production segment transformed the mode of development and continued to step up cost control while crude oil prices remained high.
As a result, our profitability has further improved and the basis for sustainable development has been reinforced. The profit from operations for the year ended December 31, 2011 was RMB219,539 million, representing an increase of 42.8% from
RMB153,703 million for the year ended December 31,2010. The exploration and production segment remains as the most important profit contributing segment of the company.

Refining and Chemicals

Turnover.Turnover increased by 27.5% from RMB664,773 million for the year ended December 31, 2010 to RMB847,711 million for the year ended December 31, 2011. The increase was primarily due to an increase in both the selling prices and sales
volumes of major refined products.

Operating Expenses. Operating expenses increased by
38.5% from RMB656,926 million for the year ended December 31, 2010 to RMB909,577 million for the year ended December 31, 2011. The operating expenses incurred for purchases, services and other increased by RMB230,170 million as compared
with last year. This was primarily due to an increase in crude oil imports by refineries and increases in international crude oil prices during 2011. Taxes other than income taxes increased by RMB10,024 million, which was primarily due to an
increase in consumption tax as compared with last year.

The cash processing cost of refineries was RMB146.27 per ton in 2011, which
was substantially the same as RMB144.04 per ton in 2010.

Profit from Operations. Due to
the fact that international crude oil prices remained high in 2011, the prices of domestic refined products were subject to government regulation and control and the demand in the petrochemical market was down, the refining and chemicals segment
recorded operating losses of RMB61,866 million for the year ended December 31, 2011, of which, the refining operations and the chemicals operations recorded operating losses of RMB60,087 million and RMB1,779 million for the year ended
December 31, 2011, respectively.

Marketing

Turnover.Turnover increased by 49.2% from RMB1,134,534 million for the year ended December 31,
2010 to RMB1,693,130 million for the year ended December 31, 2011. The increase was primarily due to an increase in both the selling prices and the sales volumes of refined products as well as an increase in revenue from the oil products
trading business.

Operating Expenses.Operating expenses increased by 49.5% from RMB1,118,578
million for the year ended December 31, 2010 to RMB1,672,477 million for the year ended December 31, 2011, of which, the operating expenses incurred for purchases, services and other increased by RMB558,011 million as compared to last
year, primarily due to an increase in the purchase cost relating to the oil products trading business.

Profit from Operations. In 2011, the marketing segment promptly took advantage of opportunities presented
by the market and organized its marketing efforts scientifically. It expanded sales and improved the quality of marketing efforts. As a result, profit from operations was RMB20,653 million for the year ended December 31, 2011, representing an
increase of 29.4% from RMB15,956 million for the year ended December 31, 2010.

Natural Gas and Pipeline

Turnover.Turnover amounted to RMB173,058 million in 2011, representing an
increase of 47.9% from RMB117,043 million in 2010. This increase was primarily due to (i) increases in both the sales and transmission volumes as well as the ongoing optimization of the sales structure by the natural gas and pipeline segment in
2011, resulting in an increase in the share of industrial gas in the sales volume; (ii) the PRC government raising the ex-factory base price of locally produced onshore natural gas by RMB0.23 per cubic meters with effect from June 1, 2010;
(iii) an increase in the sales revenue of city gas and LPG in 2011.

Operating Expenses.Operating expenses amounted to RMB157,528 million in 2011, representing an increase of 63.0% from RMB96,628 million in 2010, of which purchases, services and other increased RMB56,723 million compared to 2010. For the purposes of ensuring a safe
and stable supply of gas to city residents, utilities and key industrial users, we imported 15.53 billion cubic meters of natural gas from Central Asia and 1.83 billion cubic meters of LNG in 2011, thereby increasing the purchase costs.
Depreciation, depletion and amortization increased RMB4,376 million, which was primarily due to the fact that key projects such as the trunk line of the Second West-East Gas Pipeline commencing operation, leading to a corresponding increase in
depreciation and depletion.

Profit from Operations.Profit from operations was RMB
15,530 million for the year ended December 31, 2011, representing a decrease by 23.9% from RMB20,415 million for the previous year, which was primarily due to the effect of an increase in the losses in the sales of imported natural gas as
well as the transfer of major projects to fixed assets and the corresponding increase in depreciation, of which the aggregate losses arising from selling imported natural gas and LNG approximately amounted to RMB21,400 million.

In 2011, our overseas operations further increased their contribution to the
company. Turnover of overseas operations amounted to RMB574,212 million in 2011, or 28.6% of our total turnover. Profit before income tax expense of overseas operations amounted to RMB34,747 million in 2011, or 18.9% of our profit before income tax
expense.

The four operating segments of the company are namely exploration and production, refining and
chemicals, marketing as well as natural gas and pipeline. Overseas operations do not constitute a separate operating segment of the company. The financial data of overseas operations are included in the financial data of the respective operating
segments mentioned above.

Liquidity and Capital Resources

Our primary sources of funding include cash generated by operating activities and short-term and long-term borrowings.
Our primary uses of funds were for operating activities, acquisitions, capital expenditures, repayment of short-term and long-term borrowings and distributions of dividends to shareholders. Our payments to CNPC are limited to dividends and payments
for services provided to us by CNPC. For the year ended December 31, 2012, we distributed as dividends 45% of our reported income for the year attributable to our shareholders. See Item 8  Financial Information  Dividend
Policy for a discussion of factors which may affect the determination by our board of directors of the appropriate level of dividends.

Our financing ability may be limited by our financial condition, our results of operations and the international and domestic capital markets. Prior to accessing the international and domestic capital
markets, we must obtain approval from the relevant PRC government authorities. In general, we must obtain PRC government approval for any project involving significant capital investment for our refining and chemicals, marketing and natural gas and
pipeline segments. For a more detailed discussion of factors which may affect our ability to satisfy our financing requirements, see Item 3  Key Information  Risk Factors.

We plan to fund the capital and related expenditures described in this annual report principally through cash from
operating activities, short-term and long-term borrowings and cash and cash equivalents. Net cash flows from operating activities in the year ended December 31, 2012 was RMB239,288 million. As of December 31, 2012, we had cash and cash
equivalents of RMB43,395 million. While each of the projects described in this annual report for which significant capital expenditures will be required is important to our future development, we do not believe that failure to implement any one of
these projects would have a material adverse effect on our financial condition or results of operations. If the price of crude oil undergoes a steep decline in the future, it is likely that we would delay or reduce the scale of the capital
expenditures for our exploration and production segment.

We currently do not have any outstanding options,
warrants or other rights for any persons to require us to issue any common stock at a price below its market value. We do not currently intend to issue any such rights or to otherwise issue any common stock for a price below its market value.

In addition, we did not have for the year ended December 31, 2012, and do not currently have, any
transactions, arrangements or other relationships with unconsolidated entities or other persons that are reasonably likely to materially affect the liquidity or availability of or requirements for our capital resources.

representing a decrease of 17.5% from RMB290,155 million in the year ended December 31, 2011. This was mainly due to the combined impact of the decrease in profit, changes in accounts receivables and payables, inventories and other kinds of
working capital, and the increase in taxes and levies paid. As at December 31, 2012, we had cash and cash equivalents of RMB43,395 million. The cash and cash equivalents were mainly denominated in Renminbi (approximately 64.1% were denominated
in Renminbi, approximately 16.6% were denominated in US Dollars, approximately 15.2% were denominated in HK Dollars, approximately 1.7% were denominated in KZT and approximately 2.4% were denominated in other currencies).

December 31, 2011 was RMB283,638 million, representing a decline of 5.2% compared with RMB299,302 million used for investing activities for the year ended December 31, 2010. The decrease was primarily due to a decrease in expenditures
for the acquisition of associated entities and jointly controlled entities during 2011, partially offset by an increase in capital expenditures.

Net Cash Flows From/(Used for) Financing Activities

Our
net cash flows from financing activities for the year ended December 31, 2012 increased by RMB66,097 million to RMB75,356 million from RMB9,259 million in the year ended December 31, 2011. Such change was primarily due to an increase in

|(1) | If investments related to geological and geophysical exploration costs are included, the capital expenditures and investments for the exploration
and production segment for 2010, 2011, 2012 and the estimates for the same in 2013 would be RMB173,142 million, RMB173,760 million, RMB239,266 million and RMB250,600 million, respectively.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As of December 31, 2012, the capital expenditures contracted for at the balance sheet date but not recognized in our
consolidated financial statements were approximately RMB47,196 million.

Exploration and Production

A majority of our capital expenditures and investments relate to our exploration and production segment. For each of the
three years ended December 31, 2010, 2011 and 2012, capital expenditures in relation to the exploration and production segment amounted to RMB160,893 million, RMB162,154 million and RMB227,211 million, respectively. In 2012, our capital
expenditures were primarily used for the acquisition of mineral interests in oil and gas fields in Canada, capital investments in oil and gas development projects such as Halfaya and Rumaila of Iraq, large scale domestic oil and gas exploration
projects such as those in Changqing, Tarim, Daqing and Southwestern, and construction of key production capacities for various oil and gas fields.

We anticipate that capital expenditures for our exploration and production segment for 2013 would amount to RMB239,600 million. Domestic exploration activities will remain focused on the Peak Oil
and Gas Reserves Program and more efforts will be devoted to key oil and gas regions such as Songliao Basin, Erdos Basin, Tarim Basin, Sichuan Basin and Bohai Bay Basin, and to such unconventional oil and gas areas as coal seam gas and shale
gas. Development activities will be focused on maintaining the output of Daqing Oilfield at 40 million tons of crude oil per year, as well as increasing the oil and gas equivalent output of Changqing Oilfield to 50 million tons per year
and increasing the output of such oil and gas fields as Xinjiang, Tarim and Southwestern. Overseas operations will be focused on cooperation in oil and gas exploration and development in the Middle East, Central Asia, the Americas and the
Asia-Pacific regions.

Refining and Chemicals

Our capital expenditures for our refining and chemicals segment for each of the years ended December 31, 2010, 2011
and 2012 were RMB44,242 million, RMB42,781 million and RMB36,009 million, respectively. Among the capital expenditure made in 2012, RMB21,563 million was used on the construction of refinery facilities and RMB14,446 million was used on the
construction of chemicals facilities, including the construction of large scale refining and ethylene projects, such as the Guangxi Petrochemical, Sichuan Petrochemical, Fushun Petrochemical, Daqing Petrochemical, and Hohhot Petrochemical projects.

2011 and 2012 were RMB15,793 million and RMB15,136 million and RMB14,928 million, respectively. Our capital expenditures for the marketing segment in 2012 were mainly used for the construction of service stations, storage facilities and other
facilities for our sales network.

We anticipate that capital expenditures for our marketing segment for the
year of 2013 will amount to RMB14,300 million, which are expected to be used primarily for the construction and expansion of high-efficiency sales networks in China as well as the construction of oil and gas operating centers abroad.

Natural Gas and Pipeline

Our capital expenditures for the natural gas and pipeline segment for each of the three years ended December 31, 2010, 2011 and 2012 were RMB53,648 million, RMB62,645 million and RMB72,939 million,
respectively. Our capital expenditures for the natural gas and pipeline segment in 2012 were mainly used for the construction of the Second West-East Gas Pipeline, the Third West-East Pipeline, the Third Shaanxi-Beijing Gas Pipeline, the
Lanzhou-Chengdu Crude Oil Pipeline projects, and the Tangshan LNG project.

We anticipate that our capital
expenditures for the natural gas and pipeline segment for 2013 will amount to approximately RMB65,700 million, which are expected to be used primarily for the construction of major oil and gas transmission projects such as the Third West-East Gas
Pipeline, the Zhongwei-Guiyang Natural Gas Pipeline, the Third Daqing-Tieling Crude Oil Pipeline, and the Fourth Daqing-Tieling Crude Oil Pipeline and associated liquefied natural gas and city gas facilities.

Others

Our non-segment-specific capital expenditures and investments for each of the years ended December 31, 2010, 2011 and 2012 were RMB1,636 million, RMB1,675 million and RMB1,429 million, respectively.

Our anticipated capital expenditures for the headquarter and other segments for the year of 2013 amount to
RMB3,000 million. These planned capital expenditures and investments mainly include capital expenditures for scientific research activities and the construction of the information system.

Off-Balance Sheet Arrangements

There are no off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our
financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

A number of provinces and regions in which our oil and gas exploration and production activities are located have
promulgated environment protection regulations, which set forth specific abandonment and disposal processes for oil and gas exploration and production activities. We have established standard abandonment procedures, including plugging all retired
wells, dismantling all retired metering stations and other related facilities and performing site restoration, in response to the issuance of these provincial and regional regulations. As of December 31, 2012 the balance of assets retirement
obligation was RMB83,928 million.

Research and Development

We have a research and development management department, directly under which there are three research institutions.
Except for our branch companies which are engaged in marketing activities, each of our branch companies has its own research and development management department. Most of our branch companies have their own research institutions. Our research and
development management departments are mainly responsible for managing and coordinating the research and development activities conducted by each of the research institutions. As of December 31, 2012, we had 28,629 employees engaged in research
and development functions.

Exploration and Production

Most of Chinas major oil and gas fields are characterized by a broad range of geological conditions, and a majority of Chinas oil and gas fields are in continental sedimentary basins with
complex structures. Our research and development efforts with respect to our exploration and production business focus on:



| |  |  | theories and technologies of crude oil and natural gas exploration;
| | - |  | -------------------------------------------------------------------



| |  |  | oil and gas development theory and technology;
| | - |  | ----------------------------------------------



| |  |  | engineering technology and equipment;
| | - |  | -------------------------------------



| |  |  | theory and technology for oil and gas storage and transportation; and
| | - |  | ---------------------------------------------------------------------



| |  |  | security, energy conservation and environment protection.
| | - |  | ---------------------------------------------------------

Refining and Chemicals

Currently, our research and
development efforts in the refining and chemicals segment are focusing on the following areas:



| |  |  | technology for clean refined oil products;
| | - |  | ------------------------------------------



| |  |  | technology for unqualified heavy oil processing;
| | - |  | ------------------------------------------------

Trend Information

The world
economic situation and energy industry are developing and changing rapidly. China may encounter unexpected challenges and obstacles in maintaining a stable economic development. The increase in Chinas domestic demand for refined oil products
is still subject to many uncertainties. The competition on Chinas domestic petroleum and petrochemical market will be more intense.

Other than as disclosed above and elsewhere in this annual report, we are not aware of any trends, uncertainties, demands, commitments or events for the periods from January 1, 2010 to
December 31, 2012 that are reasonably likely to have a material adverse effect on our net revenues, income, profitability, liquidity or capital resources, or that would cause the disclosed financial information to be not necessarily indicative
of future operating results or financial conditions.

Dividend Policy

Our board of directors will declare dividends, if any, in Renminbi on a per share basis and will pay such dividends in
Renminbi with respect to A Shares and HK dollars with respect to H Shares. Any final dividend for a financial year shall be subject to shareholders approval. The Bank of New York will convert the HK dollar dividend payments and distribute them
to holders of ADSs in U.S. dollars, less expenses of conversion. The holders of the A Shares and H Shares will share proportionately on a per share basis in all dividends and other distributions declared by our board of directors.

The declaration of dividends is subject to the discretion of our board of directors. Our board of directors will take
into account factors including the following:



| |  |  | general business conditions;
| | - |  | ----------------------------



| |  |  | our financial results;
| | - |  | ----------------------



| |  |  | capital requirements;
| | - |  | ---------------------



| |  |  | contractual restrictions on the payment of dividends by us to our shareholders or by our subsidiaries to us;
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | our shareholders interests;
| | - |  | ----------------------------



| |  |  | the effect on our debt ratings; and
| | - |  | -----------------------------------



| |  |  | other factors our board of directors may deem relevant.
| | - |  | -------------------------------------------------------

We may only distribute dividends after we have made allowance for:



| |  |  | recovery of losses, if any;
| | - |  | ---------------------------



| |  |  | allocations to the statutory common reserve fund; and
| | - |  | -----------------------------------------------------



| |  |  | allocations to a discretionary common reserve fund if approved by our shareholders.
| | - |  | -----------------------------------------------------------------------------------

The allocation to the statutory funds is 10% of our income for the year attributable to our shareholders determined in
accordance with PRC accounting rules. Under PRC law, our distributable earnings will be equal to our income for the year attributable to our shareholders determined in accordance with PRC accounting rules or IFRS, whichever is lower, less
allocations to the statutory and discretionary funds.

We believe that our dividend policy strikes a balance
between two important goals:



| |  |  | providing our shareholders with a competitive return on investment; and
| | - |  | -----------------------------------------------------------------------



| |  |  | assuring sufficient reinvestment of profits to enable us to achieve our strategic objectives.
| | - |  | ---------------------------------------------------------------------------------------------

A dividend of RMB0.15250 per share (inclusive of applicable taxes) for the six months ended June 30, 2012 was paid
to the shareholders on October 24, 2012. The board of directors recommended that a final dividend of RMB0.13106 per share (inclusive of applicable taxes), which was calculated on the basis of the balance between 45% of our income for the year
attributable to our shareholders under IFRS for the year ended December 31, 2012 and the interim dividend for the six months ended June 30, 2012, should be paid. The final dividend for the year ended December 31, 2012 is subject to
the approval by the annual shareholders meeting to be held on May 23, 2013. The payment will be made to shareholders whose names appear on the register of the company at close of business on June 5, 2013.

ITEM 10 ADDITIONAL
INFORMATION

Memorandum and Articles of Association

Our Articles of Association Currently in Effect

The summary based on the significant provisions of our articles of association currently in effect has been filed with the Commission as an exhibit to our annual report on Form 20-F for the year ended
December 31, 2007. Please see our annual report on Form 20-F for the year ended December 31, 2007 for summary of our articles of association currently in effect. On March 21, 2013, our board of directors approved amendments to our
existing articles of association. Proposed changes include, among others, (i) an expansion of our scope of business and (ii) an addition of a requirement to distribute cash dividends of not be less than 30% of the net profits attributable
to the parent company under certain circumstances. The amended articles of association will become effective upon the approval of our shareholders at our 2013 annual general meeting.

Material Contracts

We have not entered into any material contracts other than in the ordinary course of business and other than those
described under Item 4  Information on the Company, Item 7  Major Shareholders and Related Party Transactions or elsewhere in this Form annual report.

Foreign Exchange Controls

The
Renminbi currently is not a freely convertible currency. We receive most of our revenues in Renminbi. A portion of our Renminbi revenues must be converted into other currencies to meet our foreign currency obligations, including:



| |  |  | debt service on foreign currency-denominated debt;
| | - |  | --------------------------------------------------



| |  |  | external capital expenditures and equity investment;
| | - |  | ----------------------------------------------------



| |  |  | purchases of imported equipment and materials; and
| | - |  | --------------------------------------------------



| |  |  | payment of any dividends declared in respect of the H Shares.
| | - |  | -------------------------------------------------------------

Under the existing foreign exchange regulations in China, we may undertake current account foreign exchange transactions,
including the payment of dividends, without prior approval from the State Administration of Foreign Exchange by producing commercial documents evidencing such transactions, provided that they are processed through Chinese banks licensed to engage in
foreign exchange transactions.

Foreign exchange transactions under the capital account, including principal
payments with respect to foreign currency-denominated obligations, continue to be subject to limitations and require the prior approval of the State Administration of Foreign Exchange. These limitations could affect our ability to obtain foreign
exchange through debt financing, or to obtain foreign exchange for capital expenditures.

We have been, and
will continue to be, affected by changes in exchange rates in connection with our ability to meet our foreign currency obligations and will be affected by such changes in connection with our ability to pay dividends on the H Shares in Hong Kong
dollars and on ADSs in U.S. dollars. We believe that we have or will be able to obtain sufficient foreign exchange to continue to satisfy these obligations. We do not engage in any financial contract or other arrangement to hedge our currency
exposure.

We are not aware of any other PRC laws, decrees or regulations that restrict the export or import
of capital or that affect the remittance of dividends, interest or other payments to non-resident holders.

Taxation

The following discussion addresses the main PRC and United States tax consequences of the ownership of H Shares or ADSs
purchased held by the investor as capital assets.

PRC Taxation

Dividends and Individual Investors

Pursuant to the Individual Income Tax Law of the PRC, all foreign individuals are subject to a 20% withholding tax on dividends paid by a PRC company on its shares listed overseas, or Overseas Shares,
unless specifically exempt by the financial authority of the State Council of the PRC. However, pursuant to the Notice on the Collection of Individual Income Tax after the Abolishment of Guoshuifa [1993] No. 045, or Circular 348, issued
by the State General Administration of Taxation of the PRC on June 28, 2011, foreign individual shareholders holding H shares, or Individual H Shareholders, in a PRC company listed in Hong Kong may be subject to different levels of withholding
taxes on dividends based on the tax treaties of their home countries with China. Individual H Shareholders, who are residents of Hong Kong or Macau or who enjoy a 10% tax rate on dividends based on the tax treaties of their home countries with
China, are subject to a withholding tax rate of 10% in respect of the H-share dividends they receive. For those Individual H Shareholders whose home countries have tax treaties with China prescribing a tax rate on dividends lower than 10%, the PRC
company, whose shares are held by such Individual H Shareholders, need to apply for such tax treatment under relevant PRC taxation regulation on behalf of the Individual H Shareholders in order for them to enjoy such tax treatment. For Individual H
Shareholders whose home countries have tax treaties with China prescribing a tax rate on dividends between 10% and 20%, the PRC company, whose shares are held by such Individual H Shareholders, shall withhold the individual income tax at the
agreed-upon tax rate. For Individual H Shareholders whose home countries have no tax treaties with China or whose home countries have tax treaties with China prescribing a tax rate on dividends higher than 20%, the PRC company shall withhold the tax
at a rate of 20%.

Dividends and Foreign Enterprises

Pursuant to the Enterprise Income Tax Law of the PRC and the implementing rules thereunder, and the Circular on
Issues Concerning the Withholding of Corporate Income Tax by PRC Resident Enterprises from Dividends Payable to H Share Non-resident Corporate Shareholders, or the Circular, each PRC resident enterprise, when paying any of its H share
non-resident corporate shareholders any dividends for 2008 and the years thereafter, is required to withhold the corporate income tax from such dividends at a uniform rate of 10%. After its receipt of any dividends on its H shares, an H share
non-resident corporate shareholder may by itself or through an agent or the withholding agent, apply to the competent taxation authority for the treatment under the applicable tax treaty and present the documents evidencing that such shareholder is
qualified to be a beneficial owner as defined under the applicable tax treaty. The competent tax authority, after having verified the correctness of such documents, shall refund the difference between the amount of the tax actually paid by such
shareholder and the amount of the tax payable by such shareholder as calculated on the basis of the rate stipulated in the applicable tax treaty.

Tax Treaties

If you are a tax resident or citizen
of a country that has entered into a double-taxation treaty with the PRC, you may be entitled to a reduction in the amount of tax withheld, if any, imposed on the payment of dividends. The PRC currently has such treaties with a number of countries,
including but not limited to:



| |  |  | the United States;
| | - |  | ------------------



| |  |  | Australia;
| | - |  | ----------



| |  |  | Canada;

| |  |  | the United Kingdom; and
| | - |  | -----------------------



| |  |  | the Netherlands.
| | - |  | ----------------

Under certain treaties, the rate of withholding tax imposed by Chinas taxation authorities may be reduced. Pursuant to the Measures for the Administration of the Enjoyment by Non-residents of the
Treatments under the Tax Treaties (Trial) promulgated by the State Administration of Taxation on August 24, 2009, non-PRC resident are required to apply for approval or filing in order to claim any benefit under tax treaties.

Capital Gains

The Individual Income Tax Law of the PRC, provides for a capital gain tax of 20% on individuals. The Provisions for Implementing the Individual Income Tax Law of the PRC, provides that the
measures to levy individual income tax on the gains realized on the sale of shares will be made in the future by the Ministry of Finance and subject to the approval of the State Council. However, the Ministry of Finance has not by far promulgated a
specific taxation method to levy tax on the capital gains realized by individual holders of H Shares or ADSs from sale of shares. If in the future such specific taxation method is promulgated, an individual holder of H Shares or ADSs may be subject
to a 20% tax on capital gains under the Individual Income Tax Law of the PRC as amended from time to time, unless exempted or reduced by an applicable double taxation treaty or relevant PRC law or regulation.

Under the Enterprise Income Tax Law of the PRC, capital gains realized by foreign enterprises which are
non-resident enterprises in the PRC upon the sale of Overseas Shares by PRC companies are generally subject to a PRC withholding tax levied at a rate of 10%, unless exempted or reduced pursuant to an applicable double-taxation treaty or other
exemptions. Currently pursuant to the Circular of the State Administration of Taxation on Printing and Issuing the Interim Measures for Administration of Withholding at Source of Income Tax of Non-resident Enterprises promulgated on
January 9, 2009, where both parties to the transaction of equity transfer are non-resident enterprises and such transaction is conducted outside the territory of PRC, the non-resident enterprise that receives incomes shall, by itself or through
its agent, declare and pay tax to the competent tax authority in the place where the Chinese enterprise whose equities have been transferred is located.

Additional PRC Tax Considerations

Under the
Provisional Regulations of the Peoples Republic of China Concerning the Stamp Duty, a stamp duty is not imposed by the PRC on the transfer of shares, such as the H Shares or ADSs, of PRC publicly traded companies that take place outside of
China.

United States Federal Income Taxation

The following is a general discussion of the material United States federal income tax consequences of purchasing, owning and disposing of the H Shares or ADSs if you are a U.S. holder, as defined below,
and hold the H Shares or ADSs as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended, or the Code. This discussion does not address all of the tax consequences relating to the purchase, ownership
and disposition of the H Shares or ADSs, and does not take into account U.S. holders who may be subject to special rules including:



| |  |  | tax-exempt entities;
| | - |  | --------------------



| |  |  | certain insurance companies;

| |  |  | U.S. holders that own 10% or more of our voting stock;
| | - |  | ------------------------------------------------------



| |  |  | U.S. holders that hold the H Shares or ADSs as part of a straddle or a hedging or conversion transaction; or
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | U.S. holders whose functional currency is not the U.S. dollar.
| | - |  | --------------------------------------------------------------

This discussion is based on the Code, its legislative history, final, temporary and proposed United States Treasury
regulations promulgated thereunder, published rulings and court decisions as in effect on the date hereof, all of which are subject to change, or changes in interpretation, possibly with retroactive effect. In addition, this discussion is based in
part upon representations of the depositary and the assumption that each obligation in the deposit agreement and any related agreements will be performed according to its terms.

You are a U.S. holder if you are:



| |  |  | a citizen or resident of the United States for United States federal income tax purposes;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | a corporation, or other entity treated as a corporation for United States federal income tax purposes, created or organized under the laws of the
United States, or any state thereof or the District of Columbia;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an estate the income of which is subject to United States federal income tax without regard to its source; or
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | a trust:
| | - |  | --------



| |  |  | subject to the primary supervision of a United States court and the control of one or more United States persons; or
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | that has elected to be treated as a United States person under applicable United States Treasury regulations.
| | - |  | -------------------------------------------------------------------------------------------------------------

If a partnership holds the H Shares or ADSs, the tax treatment of a partner generally will depend on the status of the
partner and the activities of the partnership. If you are a partner of a partnership that holds the H Shares or ADSs, we urge you to consult your tax advisors regarding the consequences of the purchase, ownership and disposition of the H Shares or
ADSs.

This discussion does not address any aspects of United States taxation other than federal income
taxation.

We urge you to consult your tax advisors regarding the United States federal, state, local and
non-United States tax consequences of the purchase, ownership and disposition of the H Shares or ADSs.

In
general, if you hold American depositary receipts evidencing ADSs, you will be treated as owner of the H Shares represented by the ADSs. The following discussion assumes that we are not a passive foreign investment company, or PFIC, as discussed
under PFIC Rules below.

Distributions on the H Shares or ADSs

The gross amount of any distribution (without reduction for any PRC tax withheld) we make on the H Shares or ADSs out of
our current or accumulated earnings and profits (as determined for United States federal income tax purposes) will be includible in your gross income as dividend income when the distribution is actually or constructively received by you, in the case
of the H Shares, or by the depositary in the case of ADSs. Subject to certain limitations, dividends paid to non-corporate U.S. holders, including individuals, since the

information program; or

that is a PFIC in the taxable year that the dividend is paid or in the prior taxable year. We believe that we will be a qualified foreign corporation so long as we are not a PFIC and we are considered eligible for the benefits of the Agreement
between the Government of the United States of America and the Government of the Peoples Republic of China for the Avoidance of Double Taxation and the Prevention of Tax Evasion with Respect to Taxes on Income, or the Treaty. Our status as a
qualified foreign corporation, however, may change.

Distributions that exceed our current and accumulated
earnings and profits will be treated as a return of capital to you to the extent of your basis in the H Shares or ADSs and thereafter as capital gain. Any dividend will not be eligible for the dividends-received deduction generally allowed to United
States corporations in respect of dividends received from United States corporations. The amount of any distribution of property other than cash will be the fair market value of such property on the date of such distribution.

If we make a distribution paid in HK dollars, you will be considered to receive the U.S. dollar value of the distribution
determined at the spot HK dollar/ U.S. dollar rate on the date such distribution is received by you or by the depositary, regardless of whether you or the depositary convert the distribution into U.S. dollars. Any gain or loss resulting from
currency exchange fluctuations during the period from the date the dividend payment is includible in your income to the date you or the depositary convert the distribution into U.S. dollars will be treated as United States source ordinary income or
loss for foreign tax credit limitation purposes.

Subject to various limitations, any PRC tax withheld from
distributions in accordance with PRC law, as limited by the Treaty, will be deductible or creditable against your United States federal income tax liability. For foreign tax credit limitation purposes, dividends paid on the H Shares or ADSs will be
foreign source income, and will be treated as passive category income or, in the case of some U.S. holders, general category income. You may not be able to claim a foreign tax credit (and instead may claim a deduction) for
non-United States taxes imposed on dividends paid on the H Shares or ADSs if you (i) have held the H Shares or ADSs for less than a specified minimum period during which you are not protected from risk of loss with respect to such Shares, or
(ii) are obligated to make payments related to the dividends (for example, pursuant to a short sale).

Sale,
Exchange or Other Disposition

Upon a sale, exchange or other disposition of the H Shares or ADSs, you
will recognize a capital gain or loss for United States federal income tax purposes in an amount equal to the difference between the U.S. dollar value of the amount realized and your tax basis, determined in U.S. dollars, in such H Shares or ADSs.
Any gain or loss will generally be United States source gain or loss for foreign tax credit limitation purposes. Capital gain of certain non-corporate U.S. holders, including individuals, is generally taxed at a reduced rate where the property has
been held more than one year. Your ability to deduct capital losses is subject to limitations. If any PRC tax is withheld from your gain on a disposition of H Shares or ADSs, such tax would only be creditable against your United States federal
income tax liability to the extent that you have foreign source income. However, in the event that such PRC tax is withheld, a U.S. holder that is eligible for the benefits of the Treaty may be able to treat the gain as foreign source income for
foreign tax credit satisfaction purposes. You are urged to consult your tax advisors regarding the United States federal income tax consequences if PRC tax is withheld from your gain on the sale or other disposition of H Shares or ADSs, including
the availability of a foreign tax credit under your particular circumstances.

If you are paid in a currency other than U.S. dollars, any gain or loss
resulting from currency exchange fluctuations during the period from the date of the payment resulting from sale, exchange or other disposition to the date you convert the payment into U.S. dollars will be treated as United States source ordinary
income or loss for foreign tax credit limitation purposes.

PFIC Rules

In general, a foreign corporation is a PFIC for any taxable year in which, after applying relevant look-through rules with
respect to the income and assets of subsidiaries:



| |  |  | 75% or more of its gross income consists of passive income, such as dividends, interest, rents and royalties; or
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the production of, passive income.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------

We believe that we did not meet either of the PFIC tests in the taxable year that ended
December 31, 2012 and believe that we will not meet either of the PFIC tests in the current or subsequent taxable years and therefore will not be treated as a PFIC for such periods. However, there can be no assurance that we will not be a PFIC
in the current or subsequent taxable years.

If we were a PFIC in any taxable year that you held the H Shares
or ADSs, you generally would be subject to special rules with respect to excess distributions made by us on the H Shares or ADSs and with respect to gain from your disposition of the H Shares or ADSs. An excess distribution
generally is defined as the excess of the distributions you receive with respect to the H Shares or ADSs in any taxable year over 125% of the average annual distributions you have received from us during the shorter of the three preceding years or
your holding period for the H Shares or ADSs. Generally, you would be required to allocate any excess distribution or gain from the disposition of the H Shares or ADSs ratably over your holding period for the H Shares or ADSs. The portion of the
excess distribution or gain allocated to a prior taxable year, other than a year prior to the first year in which we became a PFIC, would be taxed at the highest United States federal income tax rate on ordinary income in effect for such taxable
year, and you would be subject to an interest charge on the resulting tax liability, determined as if the tax liability had been due with respect to such particular taxable years. The portion of the excess distribution or gain that is not allocated
to prior taxable years, together with the portion allocated to the years prior to the first year in which we became a PFIC, would be included in your gross income for the taxable year of the excess distribution or disposition and taxed as ordinary
income.

The foregoing rules with respect to excess distributions and dispositions may be avoided or reduced
if you are eligible for and timely make a valid mark-to-market election. If your H Shares or ADSs were treated as shares regularly traded on a qualified exchange for United States federal income tax purposes and a valid
mark-to-market election was made, in calculating your taxable income for each taxable year you generally would be required to take into account as ordinary income or loss the difference, if any, between the fair market value and the adjusted tax
basis of your H Shares or ADSs at the end of your taxable year. However, the amount of loss you would be allowed is limited to the extent of the net amount of previously included income as a result of the mark-to -market election. The New York Stock
Exchange on which the ADSs are traded is a qualified exchange for United States federal income tax purposes.

Alternatively, a timely election to treat us as a qualified electing fund under Section 1295 of the Code could be
made to avoid the foregoing rules with respect to excess distributions and dispositions. You should be aware, however, that if we become a PFIC, we do not intend to satisfy record keeping requirements that would permit you to make a qualified
electing fund election.

If you own the H Shares or ADSs during any year that we are a PFIC, you must file
Internal Revenue Service, or IRS, Form 8621 for each taxable year in which you recognize gain, receive distributions, or make a reportable election with respect to such H Shares or ADSs, and file any such other form as is required by the

United States Treasury Department. We encourage you to consult your own tax advisor concerning the United States federal income tax consequences of holding the H Shares or ADSs that would
arise if we were considered a PFIC.

Backup Withholding and Information Reporting

In general, information reporting requirements will apply to dividends in respect of the H Shares or ADSs or the proceeds
of the sale, exchange, or redemption of the H Shares or ADSs paid within the United States, and in some cases, outside of the United States, other than to various exempt recipients, including corporations. In addition, you may, under some
circumstances, be subject to backup withholding with respect to dividends paid on the H Shares or ADSs or the proceeds of any sale, exchange or transfer of the H Shares or ADSs, unless you:



| |  |  | are a corporation or fall within various other exempt categories, and, when required, demonstrate this fact; or
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | provide a correct taxpayer identification number on a properly completed IRS Form W-9 or a substitute form, certify that you are exempt from backup
withholding and otherwise comply with applicable requirements of the backup withholding rules.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Any amount withheld under the backup withholding rules generally will be creditable against your United States federal income tax liability provided that you furnish the required information to the
IRS in a timely manner. If you do not provide a correct taxpayer identification number you may be subject to penalties imposed by the IRS.

Certain U.S. holders who are individuals that hold certain foreign financial assets (which may include the H Shares or ADSs) may be required to report information relating to such assets, subject to
certain exceptions. You should consult your own tax advisors regarding the effect, if any, of this requirement on your ownership and disposition of the H Shares or ADSs.

ITEM 11 QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business, we hold or issue various financial instruments which expose us to interest rate and
foreign exchange rate risks. Additionally, our operations are affected by certain commodity price movements. We historically have not used derivative instruments for hedging or trading purposes. Such activities are subject to policies approved by
our senior management. Substantially all of the financial instruments we hold are for purposes other than trading. We regard an effective market risk management system as an important element of our treasury function and are currently enhancing our
systems. A primary objective of our market risk management is to implement certain methodologies to better measure and monitor risk exposures.

##### Table of Contents

The following discussions and tables, which constitute forward-looking
statements that involve risks and uncertainties, summarize our market-sensitive financial instruments including fair value, maturity and contract terms. Such discussions address market risk only and do not present other risks which we face in
the normal course of business.

Interest Rate Risk

Our interest risk exposure arises from changing interest rates. The tables below provide information about our financial
instruments including various debt obligations that are sensitive to changes in interest rates. The tables present principal cash flows and related weighted-average interest rates at expected maturity dates. Weighted-average variable rates are based
on effective rates as of December 31, 2010, 2011 and 2012. The information is presented in Renminbi equivalents, our reporting currency.

Foreign Exchange Rate Risk

We conduct our business primarily in Renminbi. However, a portion of our RMB revenues are converted into other currencies to meet foreign currency financial instrument obligations and to pay for imported
equipment, crude oil and other materials. Foreign currency payments for imported equipment represented 7.3%, 2.5% and 6.5 % of our total payments for equipment in 2010, 2011 and 2012, respectively. Foreign currency payments for other imported
materials represented 1.0%, 0.83% and 0.09% of our total payments for materials in 2010, 2011 and 2012, respectively.

The Renminbi is not a freely convertible currency. Limitation in foreign exchange transactions imposed by the PRC government could cause future exchange rates to vary significantly from current or
historical exchange rates.

The tables below provide information about our financial instruments including
foreign currency denominated debt instruments that are sensitive to foreign currency exchange rates. The tables below summarize such information by presenting principal cash flows and related weighted-average interest rates at expected maturity
dates in RMB equivalents, using the exchange rates in effect as of December 31, 2010, 2011 and 2012, respectively.

Commodity Price Risk

We are engaged in a wide range of petroleum-related activities and purchase certain quantity of oil from the international market to meet our demands. The prices of crude oil and refined products in the
international market are affected by various factors such as changes in global and regional politics and economy, the demand and supply of crude oil and refined products, as well as unexpected events and disputes with international repercussions.
The domestic crude oil price is determined with reference to the international price of crude oil whereby the prices of domestic refined products were allowed to adjust more in line with the prices in the international crude oil market. Other than
certain subsidiaries of our company, we generally do not use any derivative instruments to evade such price risks.

Fees paid by our ADS holders

The Bank of New York Mellon, the depositary of our ADS program, collects its fees for delivery and surrender of ADSs
directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts
distributed or by selling a portion of distributable property to pay the fees. The depositary may generally refuse to provide fee-attracting services until its fees for those services are paid.

of withholding tax, for our continuing annual stock exchange listing fees and our expenses incurred in connection with investor relationship programs. In addition, the depositary has agreed to reimburse us certain amount per year of the facility,
including but not limited to, investor relations expenses or any other American depositary receipts program related expenses. The amount of such reimbursements is subject to certain limits.

ITEM 15 CONTROLS AND PROCEDURES

Evaluation of the Management on Disclosure Controls and Procedures

Our Chairman, who currently performs the function of Chief Executive Officer, and our Chief Financial Officer, after
evaluating the effectiveness of PetroChinas disclosure controls and procedures (as defined in the United States Exchange Act Rules 13a-15(e) and 15d(e)) as of the end of the period covered by this annual report, have concluded that, as of such
date, our companys disclosure controls and procedures were effective to ensure that material information required to be disclosed in the reports that we file and furnish under the Exchange Act is recorded, processed, summarized and reported,
within the time periods specified in the Securities and Exchange Commissions rules and regulations and that such information is accumulated and communicated to our companys management, including our principal executive and financial
officers, as appropriate, to allow timely decisions regarding required disclosure.

Managements Report on Internal Control over
Financial Reporting

Our companys management is responsible for establishing and maintaining adequate
internal control over financial reporting, as defined in Exchange Act Rules 13a-15(f). Under the supervision and with the participation of our companys management, including our principal executive officer and principal financial officer, our
company evaluated the effectiveness of the its internal control over financial reporting based on criteria established in the framework in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the
Treadway Commission. Based on this evaluation, our companys management has concluded that its internal control over financial reporting was effective as of December 31, 2012.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

The effectiveness of our companys internal control over financial reporting as of December 31,
2012 has been audited by PricewaterhouseCoopers (Certified Public Accountants, Hong Kong), or PwC, our companys independent registered public accountants, as stated in its report attached hereto.

Changes in Internal Control over Financial Reporting

During the year ended December 31, 2012, there were no changes in the companys internal control over financial
reporting that have materially affected, or are reasonably likely to materially affect, our companys internal control over financial reporting.

ITEM 16A AUDIT COMMITTEE FINANCIAL EXPERT

Our audit committee is composed of three non-executive independent directors, Messrs. Franco Bernabè, Mr. Cui Junhui, and Mr. Chen Zhiwu, and one non-executive director, Mr. Wang
Guoliang. See Item 6  Directors, Senior Management and Employees  Board Practices  Audit Committee. Mr. Cui Junhui, our non-executive independent director has been confirmed as a financial expert, as
defined in Item 16A of Form 20-F.

ITEM 16B CODE OF ETHICS

We adopted our code of business conduct and ethics for senior management on March 23, 2004 and our
code of business conduct and ethics for employees on March 2, 2005 and have disclosed the content of both codes on our website.

Company Limited.

ITEM 16C PRINCIPAL ACCOUNTANT FEES AND SERVICES

PwC has served as PetroChinas independent registered public accountants for each of the fiscal years
in the three-year period ended December 31, 2012, for which audited financial statements appear in this annual report on Form 20-F. The auditors are elected annually at the annual general meeting of PetroChina.

The offices of PwC are located at Princes Building, 22nd Floor, Central, Hong Kong.

The following table presents the aggregate fees for professional audit services and other services rendered by PwC to
PetroChina for each of the years ended December 31, 2011 and 2012.



|                   |  |               |    |  |      |  |    |

|Total              |  |               | 70 |  |      |  | 61 | 

The auditors remuneration above represents the annual audit fees paid by the
Company. This remuneration does not include fees of RMB 44 million and RMB 51 million for the years ended December 31, 2011 and 2012 respectively payable to PwC and its network firms which primarily relates to audit fees paid by
subsidiaries and other audit related services. These services are only the external auditor reasonably can provide and include the statutory audits and assistance with and review of documents filed with SEC.

Audit Committee Pre-approved Policies and Procedures

Currently, all audit services to be provided by our independent registered public accountants, PwC, must be approved by
our audit committee.

During 2012, services relating to all non-audit-related fees provided to us by PwC were
approved by our audit committee in accordance with the de minimis exception to the pre-approval requirement provided by paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

ITEM 16D EXEMPTIONS FROM LISTING STANDARDS FOR AUDIT COMMITTEES

We rely on an exemption contained in paragraph (b)(1)(iv)(D) of Rule 10A-3 under the Securities and Exchange Act of 1934,
as amended, from the New York Stock Exchange listing requirement that each member of the audit committee of a listed issuer must be independent. Our single non-independent audit committee member, who is a representative of CNPC, has only observer
status on the audit committee of our board of directors and is not an executive officer of our company, which qualifies us for the exemption from the independence requirements available under paragraph (b)(1)(iv)(D) of Rule 10A-3. See Item 6
 Directors, Senior Management and Employees  Board Practice  Audit Committee. We believe our reliance on this exemption does not have any adverse effect on the ability of our audit committee to act independently.

ITEM 16E PURCHASES OF EQUITY SECURITIES BY THE ISSUER
AND AFFILIATED PURCHASERS

Not applicable.

ITEM 16F CHANGE IN REGISTRANTS CERTIFYING ACCOUNTANT

In accordance with the relevant regulations concerning restrictions on the years of a registered public accountant to
consecutively provide financial auditing services to an enterprise directly owned by the central government as well as its affiliates, promulgated by the Ministry of Finance of the Peoples Republic of China and the State-owned Assets
Supervision and Administration Commission of the State Council, or the SASAC, PwC will retire as our independent registered public accountant, which will become effective upon the conclusion of our 2013 annual general meeting, and we will not
re-appoint it as our independent registered public accountant. On March 21, 2013, our supervisory board resolved to appoint KPMG as our independent registered public accountant for 2013 as proposed by our audit committee. The appointment of
KPMG will become effective upon the approval by our shareholders at our 2013 annual general meeting. PwCs report on the Companys consolidated financial statements as of and for the two fiscal years ended December 31, 2011 and 2012
did not contain an adverse opinion or disclaimer of opinion, nor were such reports qualified or modified as to uncertainty, audit scope, or accounting principles.

In connection with the audits of the Companys consolidated financial statements for each of the two fiscal years
ended December 31, 2011 and 2012 and through April 26, 2013, we did not have any disagreements (as defined in Item 16F(a)(1)(iv) of Form 20-F and related instructions to Item 16F of Form 20-F) with PwC on any matter of
accounting principles or practices, financial statement disclosure, or auditing scope and procedure, which, if not resolved to the satisfaction of PwC, would have caused them to make reference thereto in their reports on the consolidated financial
statements for such years. There was no reportable event (as described in Item 16F(a)(1)(v) of Form 20-F) during the two fiscal years ended December 31, 2011 and 2012 and through April 26, 2013. We have provided a copy of the
foregoing disclosure to PwC and requested that PwC furnished a letter addressed to the SEC stating whether or not PwC agrees with such disclosure. A copy of the letter from PwC addressed to the SEC, dated April 26, 2013, is filed as Exhibit
15.5 to this Form 20-F.

During each of the fiscal years ended December 31, 2011 and 2012, neither we nor
anyone on our behalf have consulted KPMG regarding (i) the application of accounting principles to a specified transaction, either completed or proposed; (ii) the type of audit opinion that might be rendered on our consolidated financial
statements; or (iii) any matter that was either the subject of a disagreement (as defined in Item 16F(a)(1)(iv) of Form 20-F and related instructions to Item 16-F of Form 20-F) with KPMG or a reportable event
(as described in Item 16F(a)(1)(v) of Form 20-F). Further, we have not obtained any written report or oral advice that KPMG concluded was an important factor considered by us in reaching a decision as to the accounting, auditing or financial
reporting issue.

ITEM 16G CORPORATE GOVERNANCE

We are incorporated under the laws of the PRC, with A Shares publicly traded on the Shanghai Stock Exchange, or the SSE,
and H Shares publicly traded on the Hong Kong Stock Exchange, or the HKSE, and American Deposit Shares representing H Shares on the NYSE. As a result, our corporate governance framework is subject to the mandatory provisions of the PRC Company Law
and the Corporate Governance Rules as well as the securities laws, regulations and the listing rules of Hong Kong and the United States.

The following discussion summarizes the significant differences between our corporate governance practices and those that would apply to a U.S. domestic issuer under the NYSE corporate governance rules.

Director Independence

Under the NYSE corporate governance rule 303A.01, a listed company must have a majority of independent directors on its board of directors. A company of which more than 50% of the voting power is held by
an

individual, a group or another company, or a controlled company, is not required to comply with this requirement. We are not required under the PRC Company Law and the HKSE Listing Rules to have
a majority of independent directors on our board of directors. As of the date of this report, five of our twelve directors were independent non-executive directors.

Under the NYSE corporate governance rule 303A.03, the non-management directors of a listed company must meet at regularly
scheduled executive sessions without management. There are no mandatory requirements under the PRC Company Law and the HKSE Listing Rules that a listed company should hold, and we currently do not hold, such executive sessions.

Nominating/Corporate Governance Committee

Under the NYSE corporate governance rule 303A.04, a listed company must have a nominating/corporate governance committee composed entirely of independent directors, with a written charter that covers
certain minimum specified duties, but a controlled company is not required to comply with this requirement. The Corporate Governance Code recently amended by the Stock Exchange of Hong Kong provides that issuers shall establish a nominating
committee, and a majority of which should be independent non-executive directors and the chairman shall be served by an independent non-executive director or the board chairman. We are not required under the PRC Company Law and the HKSE Listing
Rules to have, and we do not currently have, a nominating/corporate governance committee.

Compensation Committee

Under the NYSE corporate governance rule 303A.05, a listed company must have a compensation committee composed entirely of
independent directors, with a written charter that covers certain minimum specified duties. A controlled company is not required to comply with this requirement. We are not required under the PRC Company Law to have a compensation committee. Under
the Corporate Governance Code of the HKSE Listing Rules, a listed company must have a remuneration committee composed of a majority of independent non-executive directors, with a written term of references that covers certain minimum specified
duties.

We currently do not have a compensation committee composed entirely of independent directors.
However, we have an evaluation and remuneration committee including a majority of independent non-executive directors.

Corporate
Governance Guidelines

Under the NYSE corporate governance rule 303A.09, a listed company must adopt and
disclose corporate governance guidelines that cover certain minimum specified subjects. We are not required under the PRC Company Law and the HKSE Listing Rules to have, and we do not currently have, formal corporate governance guidelines. However,
we have the Articles of Association, the Rules and Procedures of Board of Directors and the Trial Implementation Rules for Compensation of Senior Management that address the following subjects:



| |  |  | director qualification standards and responsibilities;
| | - |  | ------------------------------------------------------



| |  |  | key board committee responsibilities;
| | - |  | -------------------------------------



| |  |  | director compensation; and
| | - |  | --------------------------



| |  |  | director orientation and continuing education.
| | - |  | ----------------------------------------------

In addition, under the HKSE Listing Rules, we are expected to comply with, but may choose to deviate from, certain code
provisions in the Corporate Governance Code of the Listing Rules which sets forth the principles and standards of corporate governance for listed companies. Pursuant to the HKSE Listing Rules, if we choose to deviate from any code provisions of the
Corporate Governance Code, we must disclose such deviations in our annual report.

##### Table of Contents

In 2009, we formulated the Administrative Measures on Independent Directors,
the Administrative Rules on Holding of Company Shares by Directors, Supervisors and Senior Management, the Administrative Measures on Investors Relationship and the rules and procedures of the Audit Committee, the Performance Review and
Compensation Committee, the Investment and Development Committee, and the Safety and Environmental Protection Committee. All these policies have further enhanced our corporate governance system and can ensure the better performance of duties of
directors, supervisors, senior managers and committee members.

In 2010, we adopted the revised Regulations of
PetroChina Company Limited on Disclosure of Information and formulated the Rules and Regulations of PetroChina Company Limited on the Registration of Holders of Insider Information.

In order to better adapt to the changes in applicable regulatory requirements, we have kept improving our basic corporate
governance during the reporting period. We formulated an Independent Director Observation and Inquiry Policy to provide an assurance that independent directors will be better informed of the status of the daily operation, finance management and
compliance matters of our company so as for them to better perform their duties.

Code of Business Conduct and Ethics

Under the NYSE corporate governance rule 303A.10, a listed company must adopt and disclose its code of business conduct
and ethics for directors, officers and employees, and promptly disclose any waivers of the code for directors or executive officers. See Item 16B  Code of Ethics. We are not required under the PRC Company Law and the HKSE Listing
Rules to have, and we do not currently have, a code of business conduct and ethics for directors. However, pursuant to the HKSE Listing Rules, all of our directors must comply with the Model Code for Securities Transactions by Directors of Listed
Companies (the Model Code) as set out in the Listing Rules. The Model Code sets forth required standards with which the directors of a listed company must comply in securities transactions of the listed company.

Certification Requirements

Under the NYSE corporate governance rule 303A.12(a), each listed company CEO must certify to the NYSE each year that he or she is not aware of any violation by the company of NYSE corporate governance
listing standards. Our CEO is not required under the PRC Company Law and the HKSE Listing Rules to submit, and our CEO does not currently submit, such certification.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders of PetroChina Company Limited:

In our opinion, the accompanying consolidated statement of financial position and the related consolidated statement of comprehensive
income, of changes in equity and of cash flows (consolidated financial statements) present fairly, in all material respects, the financial position of PetroChina Company Limited (the company) and its subsidiaries
(collectively referred to as the Group) at December 31, 2012 and 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012 in conformity with International
Financial Reporting Standards as issued by the International Accounting Standards Board. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2012, based
on criteria established in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Companys management is responsible for these financial statements, for
maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the Managements Report on Internal Control Over Financial Reporting appearing
under item 15. Our responsibility is to express opinions on these financial statements and on the Companys internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of
the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective
internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over
financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as
we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A
companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect
the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of
unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject
to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

PETROCHINA COMPANY LIMITED

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in millions unless otherwise stated)



|1 | ORGANIZATION AND PRINCIPAL ACTIVITIES
|- | -------------------------------------

PetroChina Company Limited (the Company) was established as a joint stock company with limited liability on
November 5, 1999 by China National Petroleum Corporation (CNPC) as the sole proprietor in accordance with the approval Guo Jing Mao Qi Gai [1999] No. 1024 Reply on the approval of the establishment of PetroChina Company
Limited from the former State Economic and Trade Commission of the Peoples Republic of China (China or PRC). CNPC restructured (the Restructuring) and injected its core business and the related assets
and liabilities into the Company. CNPC is a wholly state-owned company registered in China. The Company and its subsidiaries are collectively referred to as the Group.

The Group is principally engaged in (i) the exploration, development and production and marketing of crude oil and
natural gas; (ii) the refining of crude oil and petroleum products, production and marketing of primary petrochemical products, derivative petrochemical products and other chemical products; (iii) the marketing of refined products and
trading business; and (iv) the transmission of natural gas, crude oil and refined products and the sale of natural gas (Note 38).



|2 | BASIS OF PREPARATION
|- | --------------------

The consolidated financial statements and the statement of financial position of the Company have been prepared in accordance with the International Financial Reporting Standards (IFRSs) as
issued by the International Accounting Standards Board (IASB). The consolidated financial statements and the statement of financial position of the Company have been prepared under the historical cost convention except as disclosed in
the accounting policies below.

The preparation of financial statements in conformity with IFRS requires the
use of estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the statement of financial position and the reported amounts of revenues and expenses
during the reporting period. Although these estimates are based on managements best knowledge of current events and actions, actual results may ultimately differ from those estimates. The areas involving a higher degree of judgement or
complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note 5.



|3 | SUMMARY OF PRINCIPAL ACCOUNTING POLICIES
|- | ----------------------------------------

(a) Basis of consolidation

Subsidiaries are those
entities in which the Group has an interest of more than one half of the voting rights or otherwise has the power to govern the financial and operating policies.

A subsidiary is consolidated from the date on which control is transferred to the Group and is no longer consolidated
from the date that control ceases. The acquisition method of accounting is used to account for the acquisition of subsidiaries except for business combinations under common control. The consideration transferred for the acquisition of a subsidiary
is the fair values of the assets transferred, the liabilities incurred and the equity interests issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration
arrangement. Acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. On an
acquisition-by-acquisition basis, the Group recognizes any non-controlling interests in the acquiree either at fair value or at the non-controlling interests proportionate share of the acquirees net assets.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS  (Continued)

(Amounts in millions unless otherwise stated)



The excess of the consideration transferred,
the amount of any non-controlling interests in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the identifiable net assets is recorded as goodwill. If this is less than the fair
value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized directly in the statement of comprehensive income.

An acquisition of a business which is a business combination under common control is accounted for in a manner similar to
a uniting of interests whereby the assets and liabilities acquired are accounted for at carryover predecessor values to the other party to the business combination with all periods presented as if the operations of the Group and the business
acquired have always been combined. The difference between the consideration paid by the Group and the net assets or liabilities of the business acquired is adjusted against equity.

Intercompany transactions, balances and unrealised gains on transactions between group companies are eliminated.
Unrealised losses are also eliminated. Where necessary, accounting policies of subsidiaries have been changed to ensure consistency with the policies adopted by the Group.

For purpose of the presentation of the Companys statement of financial position, investments in subsidiaries are
accounted for at cost less impairment. Cost is adjusted to reflect changes in consideration arising from contingent consideration amendments. Cost also includes direct attributable costs of investment.

A listing of the Groups principal subsidiaries is set out in Note 19.

(b) Investments in associates

Associates are entities over which the Group has significant influence but not control, generally accompanying a shareholding of between 20% and 50% of the voting rights. Investments in associates are
accounted for by the equity method of accounting in the consolidated financial statements of the Group and are initially recognized at cost.

Under this method of accounting, the Groups share of the post-acquisition profits or losses of associates is recognized in the consolidated profit or loss and its share of post-acquisition movements
in other comprehensive income is recognized in other comprehensive income. The cumulative post-acquisition movements are adjusted against the carrying amounts of the investments. When the Groups share of losses in an associate equals or
exceeds its interest in the associate, including any other unsecured receivables, the Group does not recognize further losses, unless it has incurred obligations or made payments on behalf of the associate.

Unrealised gains on transactions between the Group and its associates are eliminated to the extent of the Groups
interest in the associates; unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. The Groups investment in associates includes goodwill identified on acquisition, net of any
accumulated loss and is tested for impairment as part of the overall balance. Goodwill represents the excess of the cost of an acquisition over the fair value of the Groups share of the net identifiable assets of the acquired associate at the
date of acquisition. Accounting policies of associates have been changed where necessary to ensure consistency with the policies adopted by the Group.

For purposes of the presentation of the Companys statement of financial position, investments in associates are accounted for at cost less impairment.

A listing of the Groups principal associates is shown in Note 17.

(c) Investments in jointly controlled entities

Jointly controlled entities are those over which the Group has contractual arrangements to jointly
share control with one or more parties. The Groups interest in jointly controlled entities is accounted for by the equity method of accounting (Note 3(b)) in the consolidated financial statements.

For purposes of the presentation of the Companys statement of financial position, investments in jointly controlled
entities are accounted for at cost less impairment.

A listing of the Groups principal jointly
controlled entities is shown in Note 17.

(d) Transactions with non-controlling interests

Transactions with non-controlling interests are treated as transactions with owners in their capacity as owners of the
Group. Gains and losses resulting from disposals to non-controlling interests are recorded in equity. The differences between any consideration paid and the relevant share of the carrying value of net assets of the subsidiary acquired resulting from
the purchase of non-controlling interests, are recorded in equity.

When the Group ceases to have control or
significant influence, any retained interest in the entity is remeasured to its fair value, with the change in carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequently accounting
for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the Group had directly disposed of the
related assets or liabilities. This may mean that amounts previously recognized in other comprehensive income are reclassified to profit or loss.

If the ownership interest in an associate is reduced but significant influence is retained, only a proportionate share of the amounts previously recognized in other comprehensive income are reclassified
to profit or loss where appropriate.

(e) Foreign currencies

Items included in the financial statements of each entity in the Group are measured using the currency of the primary
economic environment in which the entity operates (the functional currency). Most assets and operations of the Group are located in the PRC (Note 38), and the functional currency of the Company and most of the consolidated subsidiaries
is the Renminbi (RMB). The consolidated financial statements are presented in the presentation currency of RMB.

Foreign currency transactions of the Group are accounted for at the exchange rates prevailing at the respective dates of the transactions; monetary assets and liabilities denominated in foreign currencies
are translated at exchange rates at the date of the statement of financial position; gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities are recognized in the consolidated
profit or loss.

For the Group entities that have a functional currency different from the Groups
presentation currency, assets and liabilities for each statement of financial position presented are translated at the closing rate at the date of the statement of financial position. Income and expenses for each statement of comprehensive income
presented are translated at the average exchange rates for each period and the resulting exchange differences are recognized in other comprehensive income.

(f) Property, plant and equipment

Property, plant and equipment, including oil and gas properties (Note 3(g)), are initially recorded in the consolidated
statement of financial position at cost where it is probable that they will generate future economic benefits. Cost represents the purchase price of the asset and other costs incurred to bring the asset into existing use. Subsequent to their initial
recognition, property, plant and equipment are carried at cost less accumulated depreciation, depletion and amortization (including any impairment).

Depreciation, to write off the cost of each asset, other than oil and gas properties (Note 3(g)), to their residual values over their estimated useful lives is calculated using the straight-line method.

The Group uses the following useful lives for depreciation purposes:



|                        |  |  |              | 
|----------------------- |  |  | ------------ | 
|Buildings               |  |  | 8 - 40 years | 
|Equipment and Machinery |  |  | 4 - 30 years | 
|Motor vehicles          |  |  | 4 - 14 years | 
|Other                   |  |  | 5 - 12 years | 

No depreciation is provided on construction in progress until the assets are completed
and ready for use.

The assets residual values and useful lives are reviewed, and adjusted if
appropriate, at the end of each reporting period.

Property, plant and equipment, including oil and gas
properties (Note 3(g)), are reviewed for possible impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the carrying amount of a cash
generating unit exceeds the higher of its fair value less costs to sell and its value in use. Value in use is the estimated net present value of future cash flows to be derived from the cash generating unit.

Gains and losses on disposals of property, plant and equipment are determined by reference to their carrying amounts and
are recorded in the consolidated profit or loss.

Interest and other costs on borrowings to finance the
construction of property, plant and equipment are capitalized during the period of time that is required to complete and prepare the asset for its intended use. Costs for repairs and maintenance activities are expensed as incurred except for costs
of components that result in improvements or betterments which are capitalized as part of property, plant and equipment and depreciated over their useful lives.

(g) Oil and gas properties

The successful efforts
method of accounting is used for oil and gas exploration and production activities. Under this method, all costs for development wells, support equipment and facilities, and proved mineral interests in oil and gas properties are capitalized.
Geological and geophysical costs are expensed when incurred. Costs of exploratory wells are capitalized pending determination of whether the wells find proved oil and gas reserves. Proved oil and gas reserves are the estimated quantities of crude
oil and natural gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating
methods, and government regulation before the time at which contracts providing the right to operate expire, unless

evidence indicates that renewal is reasonably certain, regardless of whether the estimate is a deterministic estimate or probabilistic estimate. Existing economic conditions include prices and
costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12-month period before the ending date of the period covered by the proved oil and gas reserve report, determined as an
unweighted arithmetic average of the first-day-of-the-month price for each month within such period unless prices are defined by contractual arrangements, excluding escalations based upon future conditions. The costs shall be that prevailing at the
end of the period.

Exploratory wells in areas not requiring major capital expenditures are evaluated for
economic viability within one year of completion of drilling. The related well costs are expensed as dry holes if it is determined that such economic viability is not attained. Otherwise, the related well costs are reclassified to oil and gas
properties and are subject to impairment review (Note 3(f)). For exploratory wells that are found to have economically viable reserves in areas where major capital expenditure will be required before production can commence, the related well costs
remain capitalized only if additional drilling is underway or firmly planned. Otherwise the related well costs are expensed as dry holes. The Group does not have any significant costs of unproved properties capitalized in oil and gas properties.

The Ministry of Land and Resources in China issues production licenses to applicants on the basis of the
reserve reports approved by relevant authorities.

The cost of oil and gas properties is amortized at the
field level based on the units of production method. Units of production rates are based on oil and gas reserves estimated to be recoverable from existing facilities based on the current terms of the Groups production licenses.

(h) Intangible assets

Expenditures on acquired patents, trademarks, technical know-how and licenses are capitalized at historical cost and amortized using the straight-line method over their estimated useful lives. Intangible
assets are not subsequently revalued. The carrying amount of each intangible asset is reviewed annually and adjusted for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment
loss is recognized whenever the carrying amount of an asset exceeds its recoverable amount and is recognized in the consolidated profit or loss. The recoverable amount is measured as the higher of fair value less costs to sell and value in use.
Value in use is the estimated net present value of future cash flows to be derived from the asset.

Goodwill
arises on the acquisition of subsidiaries, associates and joint ventures and represents the excess of the consideration transferred over the interest in net fair value of the net identifiable assets, liabilities and contingent liabilities of the
acquiree and the amount of any non-controlling interests in the acquiree.

Goodwill impairment reviews are
undertaken annually or more frequently if events or changes in circumstances indicate a potential impairment. The carrying value of goodwill is compared to the recoverable amount, which is the higher of value in use and the fair value less costs to
sell. Any impairment is recognized immediately as an expense and is not subsequently reversed.

(i) Financial assets

Financial assets are classified into the following categories: financial assets at fair value through
profit or loss, held-to-maturity investments, loans and receivables and available-for-sale financial assets. The



F-12

(Amounts in millions unless otherwise stated)



classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at initial recognition. The Group has
principally loans and receivables and available-for-sale financial assets and limited financial assets at fair value through profit or loss. The detailed accounting policies for loans and receivables, available-for-sale financial assets and
financial assets at fair value through profit or loss held by the Group are set out below.

Classification

(i) Loans and receivables

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for those with maturities
greater than 12 months after the date of the statement of financial position, which are classified as non-current assets. The Groups loans and receivables comprise accounts receivable, notes receivable, other receivables, time deposits
and cash and cash equivalents. The recognition methods for loans and receivables are disclosed in the respective policy notes.

(ii) Available-for-sale financial assets

Available-for-sale financial assets are non-derivatives that are either designated in this category or not classified in any of the other categories; these are included in non-current assets unless
management intends to dispose of the investment within 12 months of the date of the statement of financial position. The Groups available-for-sale financial assets primarily comprise unquoted equity instruments.

(iii) Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss are financial assets held for trading. A financial asset is
classified in this category if acquired principally for the purpose of selling in the short term. Derivatives are also categorized as held for trading unless they are designated as hedges. Assets in this category are classified as current assets if
expected to be settled within 12 months; otherwise, they are classified as non-current.

Recognition and measurement

Regular purchases and sales of financial assets are recognized on the trade-date, the date on which the
Group commits to purchase or sell the asset. Investments are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Financial assets carried at fair value through profit
or loss are initially recognized at fair value, and transaction costs are expensed in the income statement. Financial assets are derecognized when the rights to receive cash flows from the investments have expired or have been transferred and the
Group has transferred substantially all risks and rewards of ownership.

Available-for-sale financial assets
are measured at fair value except where there are no quoted market prices in active markets and the fair values cannot be reliably measured using valuation techniques. Available-for-sale financial assets that do not have quoted market prices in
active markets and whose fair value cannot be reliably measured are carried at cost. Changes in the fair value of monetary and non-monetary securities classified as available for sale are recognized in other comprehensive income. Financial assets at
fair value through profit or loss are subsequently carried at fair value. Gains or losses arising from changes in the fair value of the financial assets at fair value through profit or loss category are presented in the income statement
within other income/ (expenses), net in the period in which they arise.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS  (Continued)

(Amounts in millions unless otherwise stated)



The Group assesses at the end of each
reporting period whether there is objective evidence that a financial asset is impaired. The amount of the impairment loss is measured as the difference between the carrying amount of the available-for-sale financial asset and the present value of
the estimated cash flows.

(j) Leases

Leases of property, plant and equipment where the Group assumes substantially all the benefits and risks of ownership are
classified as finance leases. The Group has no significant finance leases.

Leases of assets under which a
significant portion of the risks and benefits of ownership are effectively retained by the lessors are classified as operating leases. Payments made under operating leases (net of any incentives received from the lessors) are expensed on a
straight-line basis over the lease terms. Payments made to the PRCs land authorities to secure land use rights (excluding mineral properties) are treated as operating leases. Land use rights are generally obtained through advance lump-sum
payments and the terms of use range up to 50 years.

(k) Inventories

Inventories include oil products, chemical products and materials and supplies which are stated at the lower of cost and
net realisable value. Cost is primarily determined by the weighted average cost method. The cost of finished goods comprises raw materials, direct labor, other direct costs and related production overheads, but excludes borrowing costs. Net
realisable value is the estimated selling price in the ordinary course of business, less the cost of completion and selling expenses.

(l) Accounts receivable

Accounts receivable are
recognized initially at fair value and subsequently measured at amortized cost using the effective interest method, less provision made for impairment of these receivables. Such provision for impairment is established if there is objective evidence
that the Group will not be able to collect amounts due according to the original terms of the receivables. The factors the Group considers when assessing whether an account receivable is impaired include but are not limited to significant financial
difficulties of the customer, probability that the debtor will enter bankruptcy or financial reorganization and default or delinquency in payments. The amount of the provision is the difference between the assets carrying amount and the
present value of estimated future cash flows, discounted at the original effective interest rate.

(m) Cash and cash
equivalents

Cash and cash equivalents comprise cash in hand, deposits held with banks and highly
liquid investments with original maturities of three months or less from the time of purchase.

(n) Accounts payable

Accounts payable are recognized initially at fair value and subsequently measured at amortized cost
using the effective interest method.

(o) Borrowings

Borrowings are recognized initially at fair value, net of transaction costs incurred. In subsequent periods, borrowings
are stated at amortized cost using the effective interest method. Any difference between proceeds (net of transaction costs) and the redemption value is recognized in the consolidated profit or loss over the period of the borrowings.

(Amounts in millions unless otherwise stated)



General and specific borrowing costs directly
attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time
as the assets are substantially ready for their intended use or sale.

All other borrowing costs are
recognized in profit or loss in the period in which they are incurred.

Borrowings are classified as current
liabilities unless the Group has unconditional rights to defer settlements of the liabilities for at least 12 months after the reporting period.

(p) Taxation

Deferred tax is provided in full,
using the liability method, for temporary differences arising between the tax bases of assets and liabilities and their carrying values in the financial statements. However, deferred tax is not accounted for if it arises from initial recognition of
an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred tax is determined using tax rates that have been enacted or substantively
enacted by the date of the statement of financial position and are expected to apply to the period when the related deferred tax asset is realised or deferred tax liability is settled.

The principal temporary differences arise from depreciation on oil and gas properties and equipment and provision for
impairment of receivables, inventories, investments and property, plant and equipment. Deferred tax assets relating to the carry forward of unused tax losses are recognized to the extent that it is probable that future taxable income will be
available against which the unused tax losses can be utilized.

The Group also incurs various other taxes and
levies that are not income taxes. Taxes other than income taxes, which form part of operating expenses, primarily comprise a crude oil special gain levy (Note 9), consumption tax (Note 9), resource tax (Note 9), urban construction tax,
education surcharges and business tax.

(q) Revenue recognition

Sales are recognized upon delivery of products and customer acceptance or performance of services, net of value added
taxes and discounts. Revenues are recognized only when the Group has transferred to the buyer the significant risks and rewards of ownership of the goods in the ordinary course of the Groups activities, and when the amount of revenue and the
costs incurred or to be incurred in respect of the transaction can be measured reliably and collectability of the related receivables is reasonably assured.

The Group markets a portion of its natural gas under take-or-pay contracts. Customers under the take-or-pay contracts are required to take or pay for the minimum natural gas deliveries specified in the
contract clauses. Revenue recognition for natural gas sales and transmission tariff under the take-or-pay contracts follows the accounting policies described in this note. Payments received from customers for natural gas not yet taken are recorded
as deferred revenues until actual deliveries take place.

(r) Provisions

Provisions are recognized when the Group has present legal or constructive obligations as a result of past events, it is
probable that an outflow of resources will be required to settle the obligations, and reliable estimates of the amounts can be made.

(Amounts in millions unless otherwise stated)



Provision for future decommissioning and
restoration is recognized in full on the installation of oil and gas properties. The amount recognized is the present value of the estimated future expenditure determined in accordance with local conditions and requirements. A corresponding addition
to the related oil and gas properties of an amount equivalent to the provision is also created. This is subsequently depreciated as part of the costs of the oil and gas properties. Any change in the present value of the estimated expenditure other
than due to passage of time which is regarded as interest expense, is reflected as an adjustment to the provision and oil and gas properties.

(s) Research and development

Research expenditure
incurred is recognized as an expense. Costs incurred on development projects are recognized as intangible assets to the extent that such expenditure is expected to generate future economic benefits.

(t) Retirement benefit plans

The Group contributes to various employee retirement benefit plans organized by PRC municipal and provincial governments under which it is required to make monthly contributions to these plans at
prescribed rates for its employees in China. The relevant PRC municipal and provincial governments undertake to assume the retirement benefit obligations of existing and future retired employees of the Group in China. The Group has similar
retirement benefit plans for its employees in its overseas operations. Contributions to these PRC and overseas plans (defined contribution plan) are charged to expense as incurred. In addition, the Group joined the corporate annuity plan
approved by relevant PRC authorities. Contribution to the annuity plan is charged to expense as incurred. The Group currently has no additional material obligations outstanding for the payment of retirement and other post-retirement benefits of
employees in the PRC or overseas other than what described above.

(u) New accounting developments

(i) New and amended standards adopted by the Group

There are no IFRSs or IFRIC interpretations that are effective for the first time for the financial year beginning on or
after January 1, 2012 that would be expected to have a material impact on the Group.

(ii) Standards,
amendments and interpretations to existing standards that are not yet effective and have not been early adopted by the Group

The following relevant IFRSs, amendments to existing IFRSs and interpretation of IFRS have been published and are mandatory for accounting periods beginning on or after January 1, 2013 or later
periods and have not been early adopted by the Group:

Amendment to IAS 1, Financial statement
presentation regarding other comprehensive income. The main change resulting from these amendments is a requirement for entities to group items presented in other comprehensive income (OCI) on the basis of whether they are
potentially reclassifiable to profit or loss subsequently (reclassification adjustments). The amendments do not address which items are presented in OCI. The effective dates for these changes should be for annual periods beginning on or after
July 1, 2012, with earlier application permitted. The amendment is not expected to have any significant impact on the consolidated financial statements of the Group and the Group intends to adopt the amendment no later than the accounting
period beginning on or after January 1, 2013.

|4 | FINANCIAL RISK AND CAPITAL MANAGEMENT
|- | -------------------------------------

4.1 Financial risk factors

The Groups
activities expose it to a variety of financial risks, including market risk, credit risk and liquidity risk.

(a) Market
risk

Market risk is the possibility that changes in foreign exchange rates, interest rates and the prices
of oil and gas products will adversely affect the value of assets, liabilities and expected future cash flows.

(i)
Foreign exchange risk

The Group conducts its domestic business primarily in RMB, but maintains a
portion of its assets in other currencies to pay for imported crude oil, imported equipment and other materials and to meet foreign currency financial liabilities. The Group is exposed to currency risks arising from fluctuations in various foreign
currency exchange rates against the RMB. The RMB is not a freely convertible currency and is regulated by the PRC government. Limitations on foreign exchange transactions imposed by the PRC government could cause future exchange rates to vary
significantly from current or historical exchange rates.

Additionally, the Group operates internationally and
foreign exchange risk arises from future acquisitions and commercial transactions, recognized assets and liabilities and net investments in foreign operations. Certain entities in the Group might use currency derivatives to manage such foreign
exchange risk.

(ii) Interest rate risk

The Group has no significant interest rate risk on interest-bearing assets. The Groups exposure to interest rate
risk arises from its borrowings. The Groups borrowings at floating rates expose the Group to cash flow interest rate risk and its borrowings at fixed rates expose the Group to fair value interest rate risk. However, the exposure to interest
rate risk is not material to the Group. A detailed analysis of the Groups borrowings, together with their respective interest rates and maturity dates, is included in Note 28.

(iii) Price risk

The Group is engaged in a wide range of oil and gas products-related activities. Prices of oil and gas products are affected by a wide range of global and domestic factors which are beyond the control of
the Group. The fluctuations in such prices may have favorable or unfavorable impacts on the Group. The Group did not enter into any material hedging of its price risk during the year.

(b) Credit risk

Credit risk arises from cash and cash equivalents, time deposits with banks and credit exposure to customers with outstanding receivable balances.



F-17

##### Table of Contents

PETROCHINA COMPANY LIMITED

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS  (Continued)

(Amounts in millions unless otherwise stated)



A substantial portion of the Groups
cash at bank and time deposits are placed with the major state-owned banks and financial institutions in China and management believes that the credit risk is low.

The Group performs ongoing assessment of the credit quality of its customers and sets appropriate credit limits taking
into account the financial position and past history of defaults of customers. The Groups accounts receivable balances over 3 years have been substantially provided for and accounts receivable balances within one year are generally neither
past due nor impaired. The aging analysis of accounts receivable (net of impairment of accounts receivable) is presented in Note 23. The Groups accounts receivable balances that are neither past due nor impaired are with customers with no
recent history of default.

The carrying amounts of cash and cash equivalents, time deposits placed with
banks, accounts receivable, other receivables and notes receivable included in the consolidated statement of financial position represent the Groups maximum exposure to credit risk. No other financial assets carry a significant exposure to
credit risk.

The Group has no significant concentration of credit risk.

(c) Liquidity risk

Liquidity risk is the risk that the Group will encounter difficulty in meeting obligations associated with financial liabilities.

In managing its liquidity risk, the Group has access to funding at market rates through equity and debt markets,
including using undrawn committed borrowing facilities to meet foreseeable borrowing requirements.

Given the
low level of gearing and continued access to funding, the Group believes that its liquidity risk is not material.

Analysis of the Groups financial liabilities based on the remaining period at the date of the statement of financial position to the contractual maturity dates are presented in Note 28.

4.2 Capital management

The Groups objectives when managing capital are to safeguard its ability to continue as a going concern, optimise returns for owners and to minimise its cost of capital. In meeting its objectives of
managing capital, the Group may issue new shares, adjust its debt levels or the mix between short-term and long-term borrowings.

The Group monitors capital on the basis of the gearing ratio which is calculated as interest-bearing borrowings/ (interest-bearing borrowings + total equity). The gearing ratio at December 31, 2012
is 27.4% (December 31, 2011: 22.7% ).

4.3 Fair value estimation

The methods and assumptions applied in determining the fair value of each class of financial assets and financial
liabilities of the Group at December 31, 2012 and 2011 are disclosed in the respective accounting policies.

The carrying amounts of the following financial assets and financial liabilities approximate their fair value as all of them are short-term in nature: cash and cash equivalents, time deposits with
maturities over three months but within one year, accounts receivable, other receivables, trade payables, other payables and short-term



F-18

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS  (Continued)

(Amounts in millions unless otherwise stated)



borrowings. The fair values of fixed rate long-term borrowings are likely to be different from their respective carrying amounts. Analysis of the fair values and carrying amounts of long-term
borrowings are presented in Note 28.



|5 | CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS
|- | --------------------------------------------

Estimates and judgements are regularly evaluated and are based on historical experience and other factors, including
expectations of future events that are believed to be reasonable under the circumstances.

The matters
described below are considered to be the most critical in understanding the estimates and judgements that are involved in preparing the Groups consolidated financial statements.

(a) Estimation of oil and natural gas reserves

Estimates of oil and natural gas reserves are key elements in the Groups investment decision-making process. They
are also an important element in testing for impairment. Changes in proved oil and natural gas reserves, particularly proved developed reserves, will affect unit-of-production depreciation, depletion and amortization recorded in the Groups
consolidated financial statements for property, plant and equipment related to oil and gas production activities. A reduction in proved developed reserves will increase depreciation, depletion and amortization charges. Proved reserve estimates are
subject to revision, either upward or downward, based on new information, such as from development drilling and production activities or from changes in economic factors, including product prices, contract terms, evolution of technology or
development plans, etc.

(b) Estimation of impairment of property, plant and equipment

Property, plant and equipment, including oil and gas properties, are reviewed for possible impairments when events or
changes in circumstances indicate that the carrying amount may not be recoverable. Determination as to whether and how much an asset is impaired involves management estimates and judgements such as the future price of crude oil, refined and chemical
products and the production profile. However, the impairment reviews and calculations are based on assumptions that are consistent with the Groups business plans taking into account current economic conditions. Favorable changes to some
assumptions, or not updating assumptions previously made, may allow the Group to avoid the need to impair any assets, whereas unfavorable changes may cause the assets to become impaired.

(c) Estimation of asset retirement obligations

Provision is recognized for the future decommissioning and restoration of oil and gas properties. The amount of the
provision recognized is the present values of the estimated future expenditures. The estimation of the future expenditures is based on current local conditions and requirements, including legal requirements, technology, price levels, etc. In
addition to these factors, the present values of these estimated future expenditures are also impacted by the estimation of the economic lives of oil and gas properties and estimates of discount rates. Changes in any of these estimates will impact
the operating results and the financial position of the Group over the remaining economic lives of the oil and gas properties.



|6 | TURNOVER
|- | --------

Turnover represents revenues from the sale of crude oil, natural gas, refined products and petrochemical products and from the transmission of crude oil, refined products and natural gas. Analysis of
turnover by segment is shown in Note 38.

In accordance with PRC new tax rules and regulations, the threshold above which crude oil
special gain levy will be imposed (with the five-level progressive tax rates varying from 20% to 40% remaining) was raised from US$ 40 per barrel to US$ 55 per barrel. Resource tax on domestic sales of crude oil and natural gas, assessed
based on value instead of volume (with rates from 5% to 10% and the resource tax rate applicable to the Group up to 5%), was implemented nationally. Both changes in tax regulations were effective from November 1, 2011.

| | The Reserve Fund shall only be used to make good previous years losses, to expand the Companys production operations, or to increase the
capital of the Company. Upon approval of a resolution of shareholders in a general meeting, the Company may convert its Reserve Fund into share capital and issue bonus shares to existing shareholders in proportion to their original
shareholdings or to increase the nominal value of each share currently held by them, provided that the balance of the Reserve Fund after such issuance is not less than 25% of the Companys registered capital.

and IFRS. As of December 31, 2012, the Companys distributable reserve amounted to RMB 511,270 (December 31, 2011: RMB 476,103).

Proved Oil and Gas Reserve Estimates

Proved oil and gas reserves cannot be measured exactly. Reserve estimates are based on many factors related to reservoir
performance that require evaluation by the engineers interpreting the available data, as well as price and other economic factors. The reliability of these estimates at any point in time depends on both the quality and quantity of the technical and
economic data, and the production performance of the reservoirs as well as engineering judgment. Consequently, reserve estimates are subject to revision as additional data become available during the producing life of a reservoir. When a commercial
reservoir is discovered, proved reserves are initially determined based on limited data from the first well or wells. Subsequent data may better define the extent of the reservoir and additional production performance, well tests and engineering
studies will likely improve the reliability of the reserve estimate. The evolution of technology may also result in the application of improved recovery techniques such as supplemental or enhanced recovery projects, or both, which have the potential
to increase reserves.

Proved oil and gas reserves are the estimated quantities of crude oil and natural gas,
which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and
government regulation before the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether the estimate is a deterministic estimate or probabilistic estimate.

Existing economic conditions include prices and costs at which economic producibility from a reservoir is to
be determined. The price shall be the average price during the 12-month period before the ending date of the period covered by this report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such
period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions. The costs shall be that prevailing at the end of the period.

Proved developed oil and gas reserves are proved reserves that can be expected to be recovered:

a. Through existing wells with existing equipment and operating methods or in which the cost of the required equipment is
relatively minor compared with the cost of a new well.

b. Through installed extraction equipment and
infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

Proved
undeveloped oil and gas reserves are proved reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

The taxes, fees and royalty in China are domestic tax schemes and are paid in cash to PRC authorities. The proved
reserves includes quantities that are ultimately produced and sold to pay these taxes, fees and royalty.

Proved reserve estimates as of December 31, 2012, 2011 and 2010 were based on reports prepared by DeGolyer and
MacNaughton and Gaffney, Cline & Associates, independent engineering consultants.

Estimated
quantities of net proved crude oil and condensate and natural gas reserves and of changes in net quantities of proved developed and undeveloped reserves for each of the periods indicated are as follows:

Standardised Measure of Discounted
Future Net Cash Flows

The standardised measure of discounted future net cash flows related to proved oil
and gas reserves at December 31, 2012, 2011 and 2010 is based on the prices used in estimating the Groups proved oil and gas reserves, year-end costs, currently enacted tax rates related to existing proved oil and gas reserves and a 10%
annual discount factor. Future cash inflows from sales of oil and gas are net of value-added taxes. Corporate income taxes are included in future income tax expense. Other taxes are included in future production
costs as production taxes.

The standardised measure of discounted future net cash flows related to
proved oil and gas reserves at December 31, 2012, 2011 and 2010 is as follows:
