Concept Release on Possible Revisions to the Disclosure 
Requirements Relating to Oil and Gas Reserves

AGENCY: Securities and Exchange Commission.

ACTION: Concept release.

-----------------------------------------------------------------------

SUMMARY: The Commission is publishing this Concept Release to obtain 
information about the extent and nature of the public's interest in 
revising oil and gas reserves disclosure requirements which exist in 
their current form in Regulation S-K and Regulation S-X under the 
Securities Act of 1933 and the Securities Exchange Act of 1934. The 
Commission adopted the current oil and gas reserves disclosure 
requirements between 1978 and 1982. In the decades that have passed 
since the adoption of these rules, there have been significant changes 
in the oil and gas industry. Some commentators have expressed concern 
that the Commission's rules have not adapted to current practices and 
may not provide investors with the most useful picture of oil and gas 
reserves public companies hold.

I. Introduction

    Throughout the Commission's history, our focus on the information 
needs of investors in public companies has caused us to continually re-
evaluate the disclosure requirements of the federal securities laws. 
The extent and pace of changes in the oil and gas industry, and public 
concern that our oil and gas reserves disclosure requirements are not 
fully aligned with current industry practice, have led us to reconsider 
those requirements. Through this Concept Release, the Commission seeks 
public comment on our oil and gas reserves disclosure requirements.\1\ 
While we set forth a number of general and specific questions, we 
welcome comments on any other concerns commenters may have related to 
these issues.
---------------------------------------------------------------------------

    \1\ The Commission is currently considering the use of 
International Financial Reporting Standards as published by the 
International Accounting Standards Board by U.S. public companies. 
The International Accounting Standards Board is also undertaking a 
project with respect to the convergence of accounting and disclosure 
reporting practices related to all extractive industries. This 
concept release is not seeking comment with respect to those 
matters.
---------------------------------------------------------------------------

    The current oil and gas reserves disclosure requirements have been 
in place for some time. The Energy Policy and Conservation Act of 1975 
directed the Commission to ``take such steps as may be necessary to 
assure the development and observance of accounting practices to be 
followed in the preparation of accounts by persons engaged, in whole or 
in part, in the production of crude oil or natural gas in the United 
States.'' \2\ In 1978, the Commission issued Accounting Series Release 
No. 253, which amended Regulation S-X by adding new Rule 3-18,\3\ the 
precursor to Rule 4-10 of Regulation S-X.\4\ Rule 4-10 prescribes the 
financial and reporting standards for companies engaged in oil and gas 
producing activities. Rule 4-10 defines what constitutes oil and gas 
producing activities and proved reserves.\5\ Item 102 of Regulation S-
K, which the Commission adopted in 1982, requires that companies 
disclose their proved reserves and prohibits them from disclosing other 
categories of reserves.\6\ There have been significant technological 
advancements, changes in the oil and gas markets, and changes in the 
types of projects in which companies invest since the Commission 
adopted these rules and disclosure requirements. Many in the oil and 
gas industry, including some oil and gas companies, professional 
organizations and analysts, believe that our oil and gas reserves 
disclosure requirements have not kept pace with industry changes.\7\

[[Page 71611]]

Other commentators suggest that our reserves disclosure requirements 
prevent an investor from viewing the company through management's eyes. 
These commentators also believe that our rules prevent companies from 
fully presenting the reasons for their oil and gas project investment 
decisions.\8\

II. Definition of Oil and Gas Reserves

    Even though they do not appear on a company's balance sheet, oil 
and gas reserves are among the most significant assets of an oil and 
gas company. Given that they lie in deeply buried geological 
formations, oil and gas reserves are difficult to measure and, until a 
company extracts them, it can only estimate their volume.
    Item 102 of Regulation S-K sets forth the disclosure requirements 
for the physical property of a company. Instruction 3 to Item 102 
requires an oil and gas company to disclose material information about 
its proved reserves. Instruction 5 to Item 102 prohibits a company from 
disclosing reserves estimates other than proved reserves in any filing 
it makes with the Commission. Instruction 6 to Item 102 states that the 
definitions in Rule 4-10 of Regulation S-X shall apply to Item 102 with 
respect to oil and gas operations.\9\
---------------------------------------------------------------------------

    \9\ 17 CFR 229.102.
---------------------------------------------------------------------------

    Rule 4-10(a)(2) defines proved reserves as ``the estimated 
quantities of crude oil, natural gas, and natural gas liquids which 
geological and engineering data demonstrate with reasonable certainty 
to be recoverable in future years from known reservoirs under existing 
economic and operating conditions, i.e. prices and costs as of the date 
the estimate is made.''\10\ While the rule does not define ``reasonable 
certainty,'' the staff has interpreted this term to mean a level of 
certainty such that, as more information about a reservoir becomes 
available, it is more likely than not that the additional data will 
confirm or enhance the company's original estimate of the quantity it 
can ultimately recover.\11\ The staff has historically interpreted the 
requirement that the reserves be recoverable ``under existing economic 
* * * conditions,'' referred to in Rule 4-10(a)(2)(i) as ``economic 
producibility,'' to mean that the company can sell the resources for 
more than its cost to extract and transport them to market.\12\ In 
other words, the company may classify its reserves as proved only if it 
can economically produce them. Although Rule 4-10 does not specify the 
price a company should use to make this determination, the staff has 
historically applied the fiscal year end price requirements set forth 
in two related accounting standards--Statement of Financial and 
Accounting Standard No. 19 and Statement of Financial and Accounting 
Standard No. 69.\13\

    \13\ See Financial Accounting Standards Board, Statement of 
Financial Accounting Standard No. 19: Financial Accounting and 
Reporting by Oil and Gas Producing Companies (December 1977); and 
Financial Accounting Standards Board, Statement of Financial 
Accounting Standard No. 69: Disclosures About Oil and Gas Producing 
Activities-an Amendment of FASB Statements 19, 25, 33, 39 (November 
1982). These standards set forth the year-end price requirement used 
for calculating discounted future net cash flows of proved reserves.
---------------------------------------------------------------------------

    Rule 4-10(a)(2) also requires that a company be able to recover 
resources ``under existing * * * operating conditions'' before 
classifying them as proved reserves. In the absence of a definition of 
``existing operating conditions,'' the staff has historically 
interpreted this to include a ready market and a means to transport 
resources to that market.\14\ For oil, these conditions are generally 
deemed to be met because a company can easily transport oil to a sales 
point. For gas, there must be a pipeline to transport the gas to a 
sales point.\15\ If a company does not have a current means to 
transport gas, the staff assumes a ready market for gas does not 
exist.\16\ Therefore, the staff does not consider gas without a means 
of transport, known as stranded gas, to qualify for classification as 
proved reserves under Rule 4-10.\17\
---------------------------------------------------------------------------

Rulemaking Projects (November 14, 2000) available at http://www.sec.gov/divisions/corpfin/guidance/cfoilgasinterps.htm
.

    \15\ An alternative is to convert the gas to a liquid. 
Historically, however, such conversion projects have been capital 
intensive and have not always been economically justified given the 
quantity of reserves.

---------------------------------------------------------------------------

    To estimate whether it can economically produce its oil and gas 
resources, a company relies on different methods to evaluate a 
reservoir where it believes reserves exist. Rule 4-10(a)(2)(i) 
specifies the tests a company must conduct and the type of data it must 
consider to estimate, with reasonable certainty, its proved reserves. 
The company must support its economic producibility conclusion by 
either actual production from a reservoir or by a conclusive formation 
test. Although not defined in Rule 4-10, the staff has historically 
considered a conclusive formation test to include a combination of 
drilling and well flow testing.\18\
---------------------------------------------------------------------------

    \18\ Under a particular set of circumstances, the staff viewed 
this requirement slightly differently. See the subsequent discussion 
in note 24 for details regarding companies operating in the 
deepwater Gulf of Mexico.
---------------------------------------------------------------------------

    Rule 4-10(a)(4) allows a company to classify, as part of its proved 
reserves, the proved undeveloped reserves that it expects to recover 
from ``new wells on undrilled acreage, or from existing wells where a 
relatively major expenditure is required.'' \19\ Proved undeveloped 
reserves are restricted to ``offsetting productive units that are 
reasonably certain of production when drilled.'' \20\ In the absence of 
a definition of the term ``offsetting'' in Rule 4-10(a)(4), the staff 
has historically interpreted this to mean immediately adjacent.\21\ 
Rule 4-10(a)(4) does not specify a period of time during which a 
company should expect to commence drilling the new well or the period 
of time in which a company will incur a relatively major expenditure. 
Some industry commentators have expressed concern that companies 
continue to categorize quantities of proved undeveloped reserves for 
extended periods of time without taking any action to develop these 
reserves.\22\ This raises the question as to whether such quantities 
originally met, or currently meet, the reasonable certainty 
requirement.

    \22\ See, for example, Leslie Haynes, ``Defining PUDs,'' Oil & 
Gas Investor; Volume 244; Issue 5 (May 1, 2004).
---------------------------------------------------------------------------

    Finally, Rule 4-10(a)(4) allows a company to claim resources as 
proved undeveloped reserves for other undrilled units ``only where it 
can be demonstrated with certainty that there is continuity of 
production from the existing productive formation.'' \23\ Many 
companies are utilizing new technologies, such as 3-D seismic, to 
provide estimates, which they believe are reasonably certain, of proved 
undeveloped reserves more than one offset away. Nevertheless, given 
Rule 4-10(a)(4)'s requirement of certainty

[[Page 71612]]

versus reasonable certainty, the staff has considered the requirement 
of certainty to have a relatively higher threshold than reasonable 
certainty and, therefore, has not accepted estimates of proved 
undeveloped reserves based on such technologies. Some commentators have 
expressed concern that, in practice, this constitutes absolute 
certainty which they believe is too stringent a criterion.
---------------------------------------------------------------------------

    \23\ 17 CFR 210.4-10(a)(4).
---------------------------------------------------------------------------

III. The Impact of Technology

    Technological advances since 1978 have improved how companies may 
identify oil and gas resources. Advances such as 3-D and 4-D seismic 
interpretation provide increased information about reservoirs and their 
boundaries. Reservoir description tools and computer reservoir 
simulation models continue to improve as technology changes.
    While a company may currently choose to use new techniques to help 
it decide where to drill additional wells, the staff has, in nearly all 
cases, continued to require that, in the absence of actual production, 
a company support economic producibility through a conclusive formation 
test. With one exception, the staff interprets this to mean direct 
contact with the reservoir through drilling and a well-flow test.\24\
---------------------------------------------------------------------------

    \24\ In a particular set of circumstances, the staff does not 
object to companies operating in the deepwater Gulf of Mexico 
asserting reasonable certainty and economic producibility without a 
well-flow test. In 2002 and 2003, the staff reviewed the disclosure 
of oil and gas companies operating in the deepwater Gulf of Mexico. 
In response to staff comments, companies provided extensive data 
from open hole logs, core samples, wire line conveyed sampling and 
seismic surveys to support their position that a traditional well-
flow test was not necessary in that specific location. Given the 
results of this data, the staff does not object to classification of 
proved reserves in the absence of a traditional well flow test as 
long as a company's conclusions are supported by all four tests. 
This position, however, is limited to this specific geographic 
location. See the Division of Corporation Finance: Letter to 
Companies With Oil and Gas Operations in the Gulf of Mexico (April 
15, 2004) available at http://www.sec.gov/divisions/corpfin/guidance/oilgasltr04152004.htm
.

---------------------------------------------------------------------------

    Given the scarcity of relatively accessible petroleum reserves that 
companies can extract using conventional techniques, companies are 
increasingly looking to resources that are more difficult to access due 
to their geologic or geographical location or require specialized 
extraction techniques. Among these resources are tar sands and oil 
shales, both of which contain chemical compounds which can be processed 
into oil. When the Commission adopted the proved reserves definitions 
in 1978, the only effective way to extract these compounds was through 
traditional mining techniques. Since 1978, however, companies have 
developed techniques to extract these compounds using oil and gas 
drilling techniques. Despite these technological advances, Rule 4-10 
prohibits a company from including the oil it extracts from tar sands 
and oil shales in its estimation of proved reserves. Rule 4-10 states 
that ``oil and gas producing activities do not include * * * [t]he 
extraction of hydrocarbons from shale, tar sands, or coal.'' \25\ Rule 
4-10 excludes ``crude oil, natural gas, and natural gas liquids, that 
may be recovered from oil shales, coal, gilsonite and other such 
sources'' from the definition of proved reserves.\26\ Notwithstanding a 
company's ability to economically extract oil from tar sands and oil 
shales, Rule 4-10 prevents it from including these amounts in its 
estimates of proved reserves.\27\

    \25\ 17 CFR 210.4-10(a)(1)(ii)(D).
    \26\ 17 CFR 210.4-10(a)(2)(iii)(D).
    \27\ Canadian regulators have revised their definitions of oil 
reserves to include non-traditional resources such as bitumen, which 
is extracted from tar sands. See, for example, Statements of the 
Alberta Securities Commission with respect to National Instrument 
(NI) 51-101 (National Instrument 51-101 Standards of Disclosure for 
Oil and Gas Activities) available at http://www. albertasecurities.com.

---------------------------------------------------------------------------

IV. Alternative Classification Systems

    The Commission's proved reserves definitions are those used by the 
Department of Energy in 1978 and were based upon definitions used by 
the Society of Petroleum Engineers and the general industry at that 
time. Since 1978, the Society of Petroleum Engineers has made several 
significant revisions to its classification framework. It released its 
most recent version, the ``Petroleum Resources Management System,'' in 
February 2007.\28\ This system was jointly sponsored by the World 
Petroleum Council, the American Association of Petroleum Geologists and 
the Society of Petroleum Evaluation Engineers. The classification 
framework defines a broad range of reserves categories, contingent 
resources and prospective resources.\29\ We understand that oil and gas 
companies may use this classification framework to prepare reserves 
estimates for purposes other than their SEC filings and that investors 
in private financing transactions and participants in business 
combinations may use this framework as well.

    The International Accounting Standards Board is currently 
consulting with the Society of Petroleum Engineers Oil and Gas Reserves 
Committee regarding oil and gas company accounting requirements.\30\ 
The United Nations Economic Commission for Europe and the United 
Nations Economic and Social Council are currently working together to 
establish an international classification system to classify resources 
in the oil and gas and mining industries.\31\ Finally, other 
jurisdictions, such as Canada, have adopted disclosure requirements 
that share characteristics with the Petroleum Resources Management 
System.\32\

V. Independent Preparation, Assessment or Evaluation of Reserves 
Disclosure

    Although a company may engage a third party to prepare its reserves 
estimates, assess its estimates, or evaluate the proved reserves 
information in the filings that it makes with us, our rules do not 
require it to do so. While some professional organizations may require 
their members to follow certain standards in providing such services, 
it does not appear that these standards are binding or that these 
professional organizations have any specialized enforcement mechanisms 
to assure compliance with them.

VI. General Request for Comment

    As noted above, in light of the extent and pace of changes in the 
oil and gas industry and public concern that our oil and gas reserves 
disclosure requirements are not fully aligned with current industry 
practice, we are reconsidering our oil and gas reserves disclosure 
requirements. The Commission seeks public comment on our oil and gas 
reserves disclosure requirements and related issues.

Questions

    1. Should we replace our rules-based current oil and gas reserves 
disclosure requirements, which identify in specific terms which 
disclosures are required and which are prohibited, with a

[[Page 71613]]

principles-based rule? If yes, what primary disclosure principles 
should the Commission consider? If the Commission were to adopt a 
principles-based reserves disclosure framework, how could it affect 
disclosure quality, consistency and comparability?
    2. Should the Commission consider allowing companies to disclose 
reserves other than proved reserves in filings with the SEC? If we were 
to allow companies to include reserves other than proved reserves, what 
reserves disclosure should we consider? Should we specify categories of 
reserves? If so, how should we define those categories?
    3. Should the Commission adopt all or part of the Society of 
Petroleum Engineers--Petroleum Resources Management System? If so, what 
portions should we consider adopting? Are there other classification 
frameworks the Commission should consider? If the Commission were to 
adopt a different classification framework, how should the Commission 
respond if that framework is later changed?
    4. Should we consider revising the current definition of proved 
reserves, proved developed reserves and proved undeveloped reserves? If 
so, how? Is there a way to revise the definition or the elements of the 
definition, to accommodate future technological innovations?
    5. Should we specify the tests companies must undertake to estimate 
reserves? If so, what tests should we require? Should we specify the 
data companies must produce to support reserves conclusions? If so, 
what data should we require? Should we specify the process a company 
must follow to assess that data in estimating its reserves?
    6. Should we reconsider the concept of reasonable certainty? If we 
were to replace it, what should we replace it with? How could that 
affect disclosure quality? Should we consider requiring companies to 
make certain assumptions? Should we prohibit others?
    7. Should we reconsider the concept of certainty with regard to 
proved undeveloped reserves? Should we allow companies to indefinitely 
classify undeveloped reserves as proved?
    8. Should we reconsider the concept of economic producibility? If 
we were to replace it, what should we replace it with? How could that 
affect disclosure quality? Should we consider requiring companies to 
make certain assumptions? Should we prohibit others?
    9. Should we reconsider the concept of existing operating 
conditions? If we were to replace it, what should we replace it with? 
How could that affect disclosure quality? Should we consider requiring 
companies to make certain assumptions? Should we prohibit others?
    10. Should we reconsider requiring companies to use a sale price in 
estimating reserves? If so, how should we establish the price 
framework? Should we require or allow companies to use an average price 
instead of a fixed price or a futures price instead of a spot price? 
Should we allow companies to determine the price framework? How would 
allowing companies to use different prices affect disclosure quality 
and consistency? Regardless of the pricing method that is used, should 
we allow or require companies to present a sensitivity analysis that 
would quantify the effect of price changes on the level of proved 
reserves?
    11. Should we consider eliminating any of the current exclusions 
from proved reserves? How could removing these exclusions affect 
disclosure quality?
    12. Should we consider eliminating any of the current exclusions 
from oil and gas activities? How could removing these exclusions affect 
disclosure quality?
    13. Should we consider eliminating the current restrictions on 
including oil and gas reserves from sources that require further 
processing, e.g., tar sands? If we were to eliminate the current 
restrictions, how should we consider a disclosure framework for those 
reserves? What physical form of those reserves should we consider in 
evaluating such a framework? Is there a way to establish a disclosure 
framework that accommodates unforeseen resource discoveries and 
processing methods?
    14. What aspects of technology should we consider in evaluating a 
disclosure framework? Is there a way to establish a disclosure 
framework that accommodates technological advances?
    15. Should we consider requiring companies to engage an independent 
third party to evaluate their reserves estimates in the filings they 
make with us? If yes, what should that party's role be? Should we 
specify who would qualify to perform this function? If so, who should 
be permitted to perform this function and what professional standards 
should they follow? Are there professional organizations that the 
Commission can look to set and enforce adherence to those standards?
    In addition to the areas for comment identified above, we are 
interested in any other issues that commenters may wish to address and 
the benefits and costs relating to investors, issuers and other market 
participants of the possibility of revising disclosure rules pertaining 
to petroleum reserves included in Commission filings. Please be as 
specific as possible in your discussion and analysis of any additional 
issues. Where possible, please provide empirical data or observations 
to support or illustrate your comments.

    By the Commission.
