Exhibit 99.2

MANAGEMENTS DISCUSSION AND ANALYSIS

For the year ended December 31, 2013

This
managements discussion and analysis (MD&A) of financial conditions and results of operations should be read in conjunction with the audited consolidated financial statements of Penn West Petroleum Ltd. (Penn West,
we, us, our, the Company) for the years ended December 31, 2013 and 2012. The date of this MD&A is March 6, 2014. All dollar amounts contained in this MD&A are expressed in millions
of Canadian dollars unless noted otherwise.

For additional information, including our audited consolidated financial statements and Annual Information
Form, please go to our website at www.pennwest.com, in Canada to the SEDAR website at www.sedar.com or in the United States to the SEC website at www.sec.gov.

Please refer to our cautionary notes relating to forward-looking statements at the end of this MD&A. Barrels of oil equivalent (boe) may be
misleading, particularly if used in isolation. A boe conversion ratio of six thousand cubic feet of natural gas to one barrel of crude oil is based on an energy equivalency conversion method primarily applicable at the burner tip and does not
represent a value equivalency at the wellhead. Given that the value ratio based on the current price of crude oil as compared to natural gas is significantly different from the energy equivalency conversion ratio of 6:1, utilizing a conversion on a
6:1 basis is misleading as an indication of value.

Certain financial measures including funds flow, funds flow per share-basic, funds flow per
share-diluted, netback, gross revenues, sustainability ratio, recycle ratio, net operating income and net debt to funds flow included in this MD&A do not have a standardized meaning prescribed by International Financial Reporting Standards
(IFRS) and therefore are considered non-GAAP measures; accordingly, they may not be comparable to similar measures provided by other issuers. Funds flow is cash flow from operating activities before changes in non-cash working capital
and decommissioning expenditures. Funds flow is used to assess our ability to fund dividend and planned capital programs. See below for reconciliations of funds flow to its nearest measure prescribed by IFRS. Netback is the per unit of production
amount of revenue less royalties, operating costs, transportation and realized risk management gains and losses, and is used in capital allocation decisions and to economically rank projects. See Results of Operations  Netbacks
below for a calculation of our netbacks. Gross revenue is total revenues including realized risk management gains and losses and is used to assess the cash realizations on commodity sales. Sustainability ratio is a comparison of a companys
cash outflows (capital investment and dividends paid less DRIP) to its cash inflows (funds flow) and is used by the Company to assess the appropriateness of its dividend levels and the long-term ability to fund its development plans. Recycle ratio
is a comparison of our netback to our finding and development costs and is used to assess the cost of finding reserves compared to the cash received. Net operating income includes oil and gas sales, royalties, operating expenses and transportation.
Net debt to funds flow is the ratio of our net debt to our 12 months trailing funds flow and is used to assess the appropriateness of the Companys level of leverage. Net debt is the estimated amount of long-term debt plus working capital
deficit excluding the current portion of risk management and deferred funding assets.

2013 Highlights



| |  |  | Production in 2013 was within guidance at 135,093 boe per day compared to 161,195 boe per day in 2012. The decline in production was primarily due to asset dispositions completed in late 2012 and 2013.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In 2013, we closed property dispositions in non-core areas where minimal capital was allocated in our five-year plan for total proceeds of $525 million. Average annual production for the disposed properties was
approximately 11,000 boe per day.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Disposition proceeds received during 2013 were applied to the companys credit facilities with a net reduction in long-term debt of $356 million during the year, prior to foreign currency translations.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Development capital expenditures for 2013 were $816 million (2012 - $1,752 million), which was below our initial guidance of $900 million as a result of successful cost reduction strategies which lowered drilling and
completion costs at our key light-oil plays during the year.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We drilled 206 net wells (2012 - 282 net wells), excluding stratigraphic and service wells.
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | Netbacks increased to $29.69 per boe in 2013 from $26.58 per boe in 2012.
| | - |  | -------------------------------------------------------------------------



| |  |  | Funds flow for 2013 was $1,054 million compared to $1,248 million in 2012. The decline in funds flow from 2012 is mainly due to lower production volumes resulting from asset dispositions in late 2012 and the
monetization of crude oil collars and foreign exchange contracts in 2012.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Net loss was $838 million in 2013 compared to net income of $149 million in 2012. The decline in net income was largely due to non-cash impairment charges recorded on certain natural gas assets due to limited planned
development capital and lower estimated reserve recoveries on properties in Manitoba. Lower revenues from lower production volumes due to disposition activity and unrealized foreign exchange losses on the translation of US denominated senior,
unsecured notes also contributed to the decrease.

During the fourth quarter of 2013 and into 2014, we have
progressed on a number of these strategies with $486 million of dispositions closed during the period along with the recently announced $175 million disposition expected to close in the first quarter of 2014. Our development program was focused on
the Cardium and Viking areas where we increased activity levels and continued to realize significant drilling and completion cost reductions. In 2014, we will continue to focus on these key strategies outlined in our long-term plan.

Crude Oil

For 2013, WTI averaged US$98.00 per barrel compared to US$94.17 per barrel in 2012. Canadian oil price realizations remained volatile in 2013 with the
differential between WTI and Edmonton Light Sweet peaking during the fourth quarter of 2013 primarily due to refineries working through their fall turnaround schedule. The differentials subsequently narrowed and refinery utilization rates have
returned to normal. During 2013, pipeline capacity constraints at times disrupted the movement of crude oil out of Western Canada and producers increased the use of rail as a method of transportation. A series of train derailments in the second half
of 2013 has put increased scrutiny on crude by rail transport.

The U.S. Government has yet to indicate whether it will approve the Keystone XL pipeline
project. In Canada, the National Energy Board (NEB) has recommended that Enbridges Gateway project be approved subject to meeting various conditions. Additionally, Kinder Morgan has submitted a formal application to the NEB for the
expansion of their TransMountain system. The completion of these projects could ease current pipeline constraints out of Western Canada.

Currently, we
have 20,000 barrels per day of crude oil production for the first half of 2014 swapped at WTI US$93.74 per barrel and an additional 10,000 barrels per day for the same period collared between WTI US$93.20 and WTI US$101.00 per barrel.

Natural Gas

In 2013, the AECO average monthly index was
$3.12 per mcf compared to $2.40 per mcf in 2012. Entering the summer months of 2013, inventory levels were significantly lower than in previous years due to lower natural gas drilling activity over the past two years. A cool summer season across
most of North America increased inventory levels, however, due to extremely cold winter temperatures late in 2013 inventory levels have decreased and were approximately 15 percent lower year-over-year.

In 2014, cold weather and declining inventories have resulted in AECO natural gas prices that are averaging approximately $4.00 per mcf. The cold weather in
2014 led to periods of extreme volatility in natural gas prices as intra-day AECO spot prices touched approximately $40 per mcf in February. Coal prices have not responded to the increase in natural gas prices thus natural gas does not appear to be
positioned to increase market share from coal in the power generation sector should power demand increase.

We have 140,000 mcf per day of 2014 natural
gas production hedged with 90,000 mcf per day swapped at $3.90 per mcf and 50,000 mcf per day collared between $3.41 and $4.17 per mcf along with 70,000 mcf per day of 2015 natural gas production collared between $3.69 per mcf and $4.52 per mcf.

|PENN WEST 2013 |  | MANAGEMENTS DISCUSSION AND ANALYSIS 5



---

Our proved reserves continue to reflect a high percentage of developed reserves. Of total proved reserves, 75
percent were developed at December 31, 2013 (2012  78 percent). At December 31, 2013, total proved reserves as a percentage of proved plus probable reserves were 67 percent (2012  66 percent). On a proved plus probable basis
our reserves were weighted 70 percent to crude oil and liquids (2012  71 percent) and 30 percent to natural gas (2012  29 percent). Our focused drilling program during the year highlighted by the realization of significant drilling and
completions cost reductions and the potential of our waterflood programs partially offset oil weighted dispositions that occurred primarily in the fourth quarter of 2013.

Capital expenditures for 2013 have been reduced by $83 million related to joint venture carried capital (2012  $137 million).

The aggregate of the exploration and development costs incurred in the most recent financial year and the change during that year in estimated future
development costs generally will not reflect total finding and development costs related to reserves additions for that year. For comparative purposes we also disclose F&D costs excluding FDC. F&D costs are calculated in accordance with
NI 51-101, which include the change in FDC, on a proved and proved plus probable basis.

Base operations

In the second half of 2013, we increased the focus of our development programs by concentrating on three core areas of our portfolio; the Cardium, Viking and
Slave Point. For 2014, our development plans will emphasize these areas and increased application of waterflood programs. We have plans for further non-core dispositions as part of our strategy to increase the focus of our portfolio and strengthen
our balance sheet.

The company views funds flow per share as an important measure to drive shareholder returns. Increases in the metric are often
correlated to share price increases and the generation of funds flow is critical to funding the development of our extensive light-oil resources. Dividends impose natural capital investment limits on management and thus may limit shareholder
exposure to excessive operational and other risks.

Our last monthly distribution payment of $0.09 per unit as a trust was declared in December 2010 and
paid in January 2011. Subsequent to converting to a corporation in January 2011, we began paying a quarterly dividend of $0.27 per share, which continued into 2013. In June 2013, we announced a reduction of our quarterly dividend from $0.27 per
share to $0.14 per share as a means to provide increased financial flexibility. This change was effective for the third quarter dividend announced in August 2013 and paid in October 2013.

We
anticipate our net debt to funds flow ratio to improve in future years as we continue to de-lever our balance sheet and focus on light-oil, higher return projects outlined in our five-year plan.

Liquids weighting is important to increasing funds flow, as the netback on a boe basis is significantly higher than for natural gas. Our production weighting
has remained relatively consistent over the past three years, as production additions from our light-oil focused development programs have been offset by non-core disposition activity. As we move forward, our long-term plan is to focus development
in three main light-oil areas; the Cardium, Slave Point and Viking.

One of the key strategies in our long-term plan is cost reduction to realize
improvements in our netbacks which, in turn drives higher funds flow. The 2013 increase in netbacks compared to 2012 was primarily due to higher commodity prices while the decrease between 2012 and 2011 was attributed to lower commodity prices.

We monitor our recycle ratio to ensure that our capital programs provide economic benefit to our shareholders. The improvement in recycle ratio in 2013 can
largely be attributed to a more focused capital program and cost improvements across our key light-oil plays which significantly reduced our F&D cost. The increase in our netback also contributed to the improvement.

Sustainability ratio is used to ensure our capital expenditures and dividend programs are appropriate relative to our capitalization. We have targeted for a
110 percent sustainability ratio in our long-term plan. In 2013, through a focus on operational excellence across our plays, we realized significant reductions to drilling costs and cycle times, which have a positive impact on this metric.

Our production levels for 2013 were lower than 2012, primarily due to the full-year effect of non-core property dispositions
that were closed during the fourth quarter of 2012. Non-core property dispositions which closed during the fourth quarter of 2013 and the shut-in of uneconomic production during 2013, also contributed to the decline.

|(1) | Gross revenues include realized gains and losses on commodity contracts.
|--- | ------------------------------------------------------------------------

In 2013, liquid revenues have
declined from 2012 due to lower production volumes resulting from asset dispositions closed in 2012; this was partially offset by increases in crude oil prices. Natural gas revenues increased mainly due to higher prices which more than offset
production declines.

Lower commodity price realizations in 2012, partially offset by an increase in liquids production, resulted in a decline in liquids
revenue from 2011. Natural gas revenues were affected by lower production, due to our development focus on light oil, and a significant decline in natural gas prices.

|--- | -----------------------------------------------

For 2013, royalty expense decreased from 2012 primarily due
to the asset dispositions completed in 2012, which resulted in lower production volumes and revenues.

Lower commodity prices in 2012, partially offset by
the impact of wider Canadian crude oil differentials to WTI, resulted in lower royalties compared to 2011.

Average royalty rates have remained consistent
between 2013 and the comparative periods.

Operating

The reduction in
operating costs in 2013 compared to 2012 is attributed to the asset dispositions that closed late in 2012 along with field staff reductions and other cost reduction initiatives in 2013 aimed at streamlining our operations.

The decrease between 2012 and 2011 was due to lower electricity costs and acquisition and disposition activity. The temporary interruptions experienced in the
second quarter of 2011 from the wild fires in Slave Lake and flooding in Manitoba and Saskatchewan led to increased workover and maintenance activity in 2011.

Operating costs for 2013 included a realized gain on electricity contracts of $11 million (2012  $7 million and 2011  $11 million). For 2013, the
average Alberta pool price was $80.19 per MWh (2012  $64.31 per MWh and 2011  $76.21 per MWh). We currently have the following contracts in place that fix the price on our electricity consumption; in 2014 approximately 80 MW fixed at
$58.50 per MWh, in 2015 approximately 80 MW fixed at $56.69 per MWh and in 2016 approximately 25 MW fixed at $49.90 per MWh.

Financing

The
Company has an unsecured, revolving syndicated bank facility with an aggregate borrowing limit of $3.0 billion. The facility expires on June 30, 2016 and is extendible. The credit facility contains provisions for standby fees on unutilized
credit lines and stamping fees on bankers acceptances and LIBOR loans that vary depending on certain consolidated financial ratios. At December 31, 2013, approximately $2.6 billion was undrawn under this facility.

As at December 31, 2013, the value of the Companys senior unsecured notes was $2.1 billion compared to $1.9 billion at the end of 2012. No new note
issuances occurred in 2013, thus the increase is attributed to a weaker Canadian dollar compared to the US dollar partially offset by a $5 million repayment on our senior unsecured notes during the year. Summary information on our senior unsecured
notes outstanding is as follows:

|--- | --------------------------------------------

At December 31, 2013, we had $650 million of interest rate
swaps outstanding at a weighted average fixed rate of 2.65 percent which expired in January 2014. These swaps fix a portion of the interest rates under our bank facility.

At December 31, 2013, we had the following senior unsecured notes outstanding:

|(3) | The Company entered into contracts to fix the interest rate on the Pounds Sterling and Euro tranches, initially at 9.49 percent and 9.52 percent, to 9.15 percent and 9.22 percent, respectively, and to fix the exchange
rate on repayment.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our debt capital structure includes short-term financings under our syndicated bank facility and long-term instruments
through our senior unsecured notes. Financing charges in 2013 decreased compared to 2012 as the outstanding balance under our credit facility was lower. While the Companys senior unsecured notes currently contain higher interest rates than
drawings under our syndicated bank facilities held in short-term money market instruments, we believe the long-term nature and fixed interest rates inherent in the senior notes are favourable for a portion of our debt capital structure.

The interest rates on any non-hedged portion of the Companys credit facility are subject to fluctuations in short-term money market rates as advances on
the credit facility are generally made under short-term instruments. As at December 31, 2013, none (2012  four percent) of our long-term debt instruments were exposed to changes in short-term interest rates.

Realized gains and losses on the interest rate swaps are recorded as financing costs. For 2013 an expense of $9
million (2012  $9 million) was recorded in financing costs to reflect that the floating interest rate was lower than the fixed interest rate transacted under our interest rate swaps.

Share-Based Compensation

Share-based compensation expense is
related to our Stock Option Plan (the Option Plan), our Common Share Rights Incentive Plan (the CSRIP) which includes restricted options, restricted rights and share rights, our Long-Term Retention and Incentive Plan
(LTRIP), our Deferred Share Unit Plan (the DSU) and our Performance Share Unit Plan (PSU).

Share-based compensation
consisted of the following:

The share price used in the fair value calculation of the
Restricted Rights, LTRIP, DSU and PSU obligations at December 31, 2013 was $8.87 (2012  $10.80 and 2011  $20.19).

The decrease in G&A expense from the comparable periods is due to staff reductions in 2013. G&A on a per boe basis has
increased due to lower production volumes primarily resulting from the effect of the dispositions closed in the fourth quarter of 2012.

Restructuring
Expense

During 2013, significant changes were made to our cost structure to increase operational efficiencies through reducing our staffing levels
both at our head office and in the field. We recorded a restructuring charge of $38 million ($0.76 per boe); with $32 million related to office and field severances and $6 million in accelerated PSU payments.

In 2012, we incurred $13 million of restructuring charges related to severance payments as a result of internal reorganizing.

The decrease in our D&D expense in 2013 is attributed to lower production volumes due to the dispositions that closed in
2012. The increase in 2012 compared to 2011 was related to our capital spending substantially weighted to light-oil development and the divestment of non-core properties.

In 2013, we recorded an impairment charge in the fourth quarter on certain non-core natural gas assets in British Columbia and Alberta primarily due to
limited planned development capital. Additionally, an impairment charge was recorded in an oil weighted area in Manitoba due to lower estimated reserve recoveries. In 2012, we recorded an impairment charge during the fourth quarter related to
legacy, base natural gas assets in northern British Columbia as a result of low natural gas prices.

The accretion per boe decreased in 2013 compared to

In 2013, the deferred income tax recovery was primarily due to impairment charges recorded during the fourth quarter of 2013.
Also included in the recovery in 2013 was a $7 million income tax refund related to a legacy tax dispute that was resolved.

In 2012, we recorded a
deferred tax expense primarily due to gains on property dispositions and from unrealized risk management gains.

The deferred tax recovery for the year
ended December 31, 2011 includes a $304 million recovery related to the tax rate differential on our conversion from a trust to an E&P company on January 1, 2011.

We record unrealized foreign exchange gains or losses to translate the U.S., UK and Euro denominated senior, unsecured notes
and the related accrued interest to Canadian dollars using the exchange rates in effect on the balance sheet date. The unrealized losses in 2013 and 2011 were due to the weakening of the Canadian dollar relative to the US dollar. The unrealized gain
in 2012 can be attributed to the Canadian dollar strengthening compared to the US dollar. As at December 31, 2013, we have 39 percent of the repayment of our US denominated senior, unsecured notes hedged at US$1.00 equals CAD$1.00 and all of
the UK and Euro denominated senior, unsecured notes under cross currency swaps. The offsetting gains on these hedges were $39 million for 2013 based on the exchange rate on December 31, 2013 of USD/CAD of 1.06, and are recorded as risk
management.

|(1) | Funds flow is a non-GAAP measure. See Calculation of Funds Flow.
|--- | ------------------------------------------------------------------

The decline in funds flow in
2013 from 2012 is mainly due to lower production volumes resulting from asset dispositions closed in late 2012 and the monetization of crude oil collars and foreign exchange contracts in 2012. Funds flow in 2012 decreased from 2011 as a result of
lower commodity price realizations and disposition activity.

The decline in net income in 2013 compared to 2012 was largely due to impairment charges
recorded on certain natural gas assets as a result of limited planned development capital and changes to lower estimated reserve recoveries in Manitoba. Lower revenues from lower production volumes due to disposition activity and unrealized foreign
exchange losses from the weakening of the Canadian dollar compared to the US dollar also contributed to the decrease.

In 2012, net income decreased from
2011 as lower revenues from the decline in commodity prices and an impairment charge on legacy natural gas properties were partially offset by gains from property dispositions and risk management gains.

|(1) | Exploration and development capital includes costs related to Property, Plant and Equipment and Exploration and Evaluation activities.
|--- | --------------------------------------------------------------------------------------------------------------------------------------

In the second half of 2013, our development programs were focused on the Cardium, Viking and Slave Point, consistent with our long-term strategy. Capital
expenditures have decreased compared to 2012 and 2011 as we re-focused our development plans and reduced our drilling and completions cost per well.

Exploration and evaluation (E&E) capital expenditures



|                         |  |                        |    |  |      |   |     |      |  |   |     |

|E&E capital expenditures |  | $                      | 80 |  |      | $ | 228 |      |  | $ | 321 | 

During 2013, we had non-cash E&E expenses of $44 million (2012  $17 million) primarily related to land expiries and
to minor properties which have no capital allocations in our long-term strategy.

Gain (loss) on asset dispositions



|                                  |  |                        |     |   |      |   |     |      |  |   |     |

The gains and losses recorded in each year relate to non-core property dispositions. In 2013, we completed the phase one
portion of our disposition strategy outlined in our long-term plan and divested non-core assets to improve our balance sheet and focus our operations. We realized net proceeds of $525 million from our net disposition activity during the year which
had associated production of approximately 11,000 boe per day, weighted 65 percent to liquids. Proceeds were applied to our credit facility.

Goodwill



|                                   |  |                        |       |  |      |   |       |      |  |   |       |

We recorded goodwill on our acquisitions of Petrofund Energy Trust, Canetic Resources Trust and Vault Energy Trust in prior
years. In 2013, we reduced our goodwill balance by $54 million as a result of allocating goodwill to non-core property dispositions completed in prior years of which $25 million related to 2012 and $29 million related to prior years. The goodwill
reduction in 2012 recorded against gains on dispositions and resulted in a decrease to earnings per share of $0.06. The reduction to years prior to this was offset to January 1, 2012 retained earnings. We recorded an impairment charge of $48
million related to a non-core play to which goodwill was associated and disposed of $6 million related to non-core asset dispositions during 2013.

Environmental and Climate Change

The oil and gas industry has a number of environmental risks and hazards and is subject to regulation by all levels of government. Environmental legislation
includes, but is not limited to, operational controls, site restoration requirements and restrictions on emissions of various substances produced in association with oil and natural gas operations. Compliance with such legislation could require
additional expenditures and a failure to comply may result in fines and penalties which could, in the aggregate and under certain assumptions, become material.

We are dedicated to reducing the environmental impact from our operations through our environmental programs which include resource conservation, CO2 sequestration, water management and site abandonment/reclamation. Operations are continuously monitored to minimize the environmental impact and sufficient capital is allocated to reclamation and
other activities to mitigate the impact on the areas in which we operate.

The amount of future cash dividends may vary depending on a variety of factors and conditions which can include,
but are not limited to, fluctuations in commodity markets, production levels and capital investment plans. Our dividend level could change based on these and other factors and is subject to the approval of our Board of Directors. For further
information regarding our dividend policy, including the factors that could affect the amount of quarterly dividend that we pay and the risks relating thereto, see Dividends and Dividend Policy  Dividend Policy in our Annual
Information Form, which is available on our website at www.pennwest.com, on the SEDAR website at www.sedar.com, and on the SEC website at www.sec.gov.

Liquidity

The Company currently has an unsecured, revolving,
syndicated bank facility with an aggregate borrowing limit of $3.0 billion expiring on June 30, 2016. For further details on our debt instruments, please refer to the Financing section of this MD&A.

We actively manage our debt portfolio and consider opportunities to reduce or diversify our debt capital structure. We consider operating and financial risks
and take actions as appropriate to limit our exposure to certain risks. We maintain close relationships with our lenders and agents to monitor credit market developments. These actions and plans aim to increase the likelihood of maintaining our
financial flexibility to capture opportunities available in the markets in addition to the continuation of our capital and dividend programs and hence the longer-term execution of our business strategies.

The Company has a number of covenants related to its syndicated bank facility and senior, unsecured notes. On December 31, 2013, the Company was in
compliance with all of these financial covenants which consist of the following:



|                              |  |               |  |                   |     |

|                              |  | Limit         |  | December 31, 2013 |    
|Senior debt to EBITDA (1)     |  | Less than 3:1 |  |                   | 2.2 |  
|Total debt to EBITDA (1)      |  | Less than 4:1 |  |                   | 2.2 |  
|Senior debt to capitalization |  | Less than 50% |  |                   | 24  | %
|Total debt to capitalization  |  | Less than 55% |  |                   | 24  | %



|(1) | EBITDA is calculated in accordance with Penn Wests lending agreements wherein unrealized risk management gains and losses and impairment provisions are excluded.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------

The senior, unsecured notes contain change of control provisions whereby if a change of control occurs, the Company may be required to offer to prepay the
notes, which the holders have the right to refuse.

Outlook

This outlook section is included to provide shareholders with information about our expectations as at March 6, 2014 for production and capital
expenditures in 2014 and readers are cautioned that the information may not be appropriate for any other purpose. This information constitutes forward-looking information. Readers should note the assumptions, risks and discussion under
Forward-Looking Statements and are cautioned that numerous factors could potentially impact our capital expenditure levels and production performance for 2014, including our non-core asset disposition program.

For 2014, our development capital expenditures budget is $900 million. Our forecast 2014 average production is 101,000 boe per day to 106,000 boe per day.

For the first quarter of 2014, we expect our development capital budget to be approximately $230 million.

There have been no changes to our guidance from our 2014 forecast average production outlined in our January 21, 2014 press release Penn West
Provides Fourth Quarter 2013 Operational Update and Announces Additional Non-Core Asset Dispositions for Expected Proceeds of Approximately $175 Million and our 2014 development capital expenditures budget outlined in our November 6, 2013
press release Penn West Announces its Financial Results for the Third Quarter Ended September 30, 2013 released and filed on SEDAR at www.sedar.com and on EDGAR at www.sec.gov.

We are involved in various claims and litigation in the normal course of business and record provisions for claims as
required.

Financial

Gross
revenues and funds flow decreased in the fourth quarter of 2013 compared to 2012 primarily due to lower production volumes as a result of asset dispositions occurring in both periods.

Net loss increased during the fourth quarter of 2013 compared to 2012 primarily due to non-cash impairment charges on certain non-core natural gas assets due
to limited planned development capital and lower estimated reserve recoveries in Manitoba.

We closed non-core asset dispositions during the fourth
quarter for proceeds of $486 million. The proceeds were applied to reduce bank debt.

Operations

Development capital was $208 million during the fourth quarter of 2013 as we concentrated our drilling program in the Lodgepole and Crimson Lake areas of the
Cardium and Dodsland area of the Viking and drilled a total of 56 net wells. Additionally, we initiated a waterflood pilot in the Willesden Green area of the Cardium.

Average production in the fourth quarter of 2013 was 123,995 boe per day after the impact of net asset dispositions. During the fourth quarter of 2013, we
completed net asset dispositions with combined production of approximately 10,800 boe per day.

In the fourth quarter of 2013, WTI crude oil prices
averaged US$97.50 per barrel compared to US$105.80 per barrel in the third quarter of 2013 and US$88.20 per barrel for the fourth quarter of 2012. Differentials widened during the period with Edmonton light sweet oil trading at a discount of $15.02
per barrel to WTI during the fourth quarter of 2013 (2012  $3.46 per barrel) compared to a discount of $4.80 per barrel during the third quarter of 2013. In the fourth quarter of 2013, the AECO Monthly Index averaged $3.15 per mcf compared to
$2.67 per mcf in the third quarter of 2013 and $3.06 per mcf for the fourth quarter of 2012.

Netbacks were comparable quarter over quarter at $26.66 per
boe compared to $26.84 per boe in the fourth quarter of 2012.

Disclosure Controls and Procedures

As of December 31, 2013, an internal evaluation was carried out under the supervision of our President and Chief Executive Officer (the CEO)
and Executive Vice President and Chief Financial Officer (the CFO) of the effectiveness of Penn Wests disclosure controls and procedures as defined in Rule 13a-15 under the US Securities Exchange Act of 1934 (the Exchange
Act) and as defined in Canada by National Instrument 52-109, Certification of Disclosure in Issuers Annual and Interim Filings (NI 52-109). Based on that evaluation, the CEO and the CFO concluded that as of December 31,
2013 the disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed in the reports that Penn West files or submits under the Exchange Act or under Canadian securities legislation
is recorded, processed, summarized and reported, within the time periods specified in the rules and forms therein. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required
to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuers management, including its CEO and CFO, or persons performing similar functions, as appropriate to allow
timely decisions regarding required disclosure.

Internal Control over Financial Reporting (ICOFR)

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (ICOFR). As of December 31, 2013, an
internal evaluation was carried out by management under the supervision and with the participation of our CEO and CFO of the effectiveness of our ICOFR as defined in Rule 13a-15 under the Exchange Act and as defined in Canada by NI 52-109. The
assessment was based on the framework in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO 1992). Based on that evaluation, management concluded that as of
December 31, 2013 our ICOFR was effective. We have certified our ICOFR and obtained auditor attestation of the operating effectiveness of our internal control over financial reporting in conjunction with our 2013 year-end audited consolidated
financial statements.

Our internal control over financial reporting as of December 31, 2013 has been audited by KPMG LLP, an independent registered
public accounting firm, as stated in their attestation report which is included herein.

In 2013, we reduced our goodwill balance by $54 million to
reflect goodwill being associated with asset dispositions of prior years, this change was made retroactively. As a result, we made enhancements to our methodology for associating goodwill to cash generating units and dispositions. No other changes
in our ICOFR were made during the year ended December 31, 2013 that have materially affected, or are reasonably likely to materially affect, our ICOFR.

New Accounting Pronouncements

During 2013, we adopted
the following standards all of which were applied retroactively except for IFRS 13 and the IAS 36 amendment which was applied prospectively.

IFRS 7
Financial Instruments - Disclosures was amended, effective January 1, 2013, outlining new disclosure requirements when offsetting financial assets and liabilities. The additional disclosure requirements have been reflected in this
reporting period.

IFRS 10 Consolidated Financial Statements outlines a new methodology to determine whether to consolidate an investee. This
new standard became effective on January 1, 2013. There was no impact to us on adoption of this standard.

IFRS 11 Joint Arrangements
outlines the accounting treatment for joint arrangements, notably joint operations which will follow the proportionate consolidation method and joint ventures which will follow the equity accounting method. This new standard became effective on
January 1, 2013 and applies to our interest in the Peace River Oil Partnership. We determined that our interest in the Peace River Oil Partnership continues to be a joint operation under the new standard; thus continue to proportionately record
its interest in the assets, liabilities, revenue, and expenses in the Partnership.

IFRS 12 Disclosure of Interests in Other Entities outlines
disclosure requirements for interests in subsidiaries, joint arrangements, associates and unconsolidated structured entities. These disclosure requirements became effective on January 1, 2013. We have updated our disclosures as required.

IFRS 13 Fair Value Measurement defines fair value, provides guidance on measuring fair value and outlines disclosure requirements for fair value
measurement. This standard applies when another IFRS standard requires fair value measurements or disclosures, with some exceptions including IFRS 2 Share based payments and IAS 17 Leases. This new standard became effective
on January 1, 2013. There was no impact to us on adoption of this standard.

IAS 36 Impairment of assets was amended to reverse the
unintended requirement in IFRS 13 Fair Value Measurement to disclose the recoverable amount of every cash-generating unit to which significant goodwill or indefinite-lived intangible assets have been allocated. Under the amendments,
recoverable amount is required to be disclosed only when an impairment loss has been recognized or reversed. We have early adopted these amendments and updated our disclosures as required.

Future Accounting Pronouncements

In May 2011, the International Accounting Standards Board issued IFRS 9 Financial Instruments which outlines a new methodology for the recognition
and measurement requirements for financial instruments. This new standard will eventually replace IAS 39 Financial Instruments: Recognition and Measurement. This standard is still in development and no effective date has been set;
therefore, we cannot assess the impact of this standard at this time.

The International Accounting Standards Board issued amendments to IAS 32,
Financial Instruments: Presentation, which clarify the requirements for offsetting financial assets and liabilities. The amendments clarify when an entity has a legally enforceable right to offset and certain other requirements that are
necessary to present a net financial asset or liability. The amendments are required to be applied retrospectively for annual periods beginning on or after January 1, 2014. We are currently assessing the impact of this standard at this time.

In May 2013, IFRIC 21 Levies was issued and provides guidance on accounting for levies in accordance with the requirements of IAS 37,
Provisions, Contingent Liabilities and Contingent Assets.The interpretation defines a levy as an outflow from an entity imposed by a government in accordance with legislation. It also notes that levies do not arise from executory
contracts or other contractual arrangements. The interpretation also confirms that an entity recognizes a liability for a levy only when the triggering event specified in the legislation occurs. This IFRIC is effective for annual periods commencing
on or after January 1, 2014 and is to be applied retrospectively. We intend to adopt IFRIC 21 in our financial statements for the annual period beginning January 1, 2014. The extent of the impact of adoption of the amendments has not yet
been determined.

Off-Balance-Sheet Financing

We
have off-balance-sheet financing arrangements consisting of operating leases. The operating lease payments are summarized in the Contractual Obligations and Commitments section.

Critical Accounting Estimates

Our significant accounting
policies are detailed in Note 3 to our audited consolidated financial statements. In the determination of financial results, we must make certain critical accounting estimates as follows:

Depletion and Impairments

Costs of developing oil and natural
gas reserves are capitalized and depleted against associated oil and natural gas production using the unit-of-production method based on the estimated proved plus probable reserves with forecast commodity pricing.

All of our reserves were evaluated or audited by Sproule Associates Limited (SAL), an independent, qualified reserve evaluation engineering firm.
Our reserves are determined in compliance with National Instrument 51-101. The evaluation of oil and natural gas reserves is, by its nature, based on complex extrapolations and models as well as other significant engineering, reservoir, capital,
pricing and cost assumptions. Reserve estimates are a key component in the calculation of depletion and are an important component in determining the recoverable amount in impairment tests. The determination of the recoverable amount involves
estimating the higher of an assets fair value less costs to sell or its value-in-use, the latter of which is based on its discounted future cash flows using an applicable discount rate. To the extent that the recoverable amount, which could be
based in part on our reserves, is less than the carrying amount of property, plant and equipment, a write-down against income is recorded. In 2013, we recorded a before tax impairment charge totalling $742 million related to certain non-core natural
gas assets in British Columbia and Alberta due to limited planned development capital and in Manitoba due to lower estimated reserve recoveries. In 2012, we recorded a $277 million impairment related to certain properties in northern British
Columbia, primarily due to weak forward natural gas price forecasts on December 31, 2012.

Decommissioning Liability

The decommissioning liability is the present value of our future statutory, contractual, legal or constructive obligations to retire long-lived assets
including wells, facilities and pipelines. The liability is recorded on the balance sheet with a corresponding increase to the carrying amount of the related asset. The recorded liability increases over time to its future liability amount through
accretion charges to income. Revisions to the estimated amount or timing of the obligations are reflected as increases or decreases to the recorded decommissioning liability. Actual decommissioning expenditures are charged to the liability to the
extent of the then-recorded liability. Amounts capitalized to the related assets are amortized to income consistent with the depletion or depreciation of the underlying asset. Note 10 to our audited consolidated financial statements details the
impact of these accounting standards.

Financial Instruments

Financial instruments included in the balance sheets consist of accounts receivable, fair values of derivative financial instruments, current liabilities and
long-term debt. Except for the senior notes, the fair values of these financial instruments approximate their carrying amounts due to the short-term maturity of the instruments, the mark-to-market values recorded for the financial instruments and
the market rate of interest applicable to the bank debt. The estimated fair value of the senior notes is disclosed in Note 9 to our audited consolidated financial statements.

Our revenues from the sale of crude oil, natural gas liquids and natural gas are directly impacted by changes to the underlying commodity prices. To ensure
that funds flows are sufficient to fund planned capital programs and dividends, financial instruments including collars may be utilized from time to time. Collars ensure that commodity prices realized will fall into a contracted range for a
contracted sales volume.

Substantially all of our accounts receivable are with customers in the oil and natural gas industry and are subject to normal
industry credit risk. We may, from time to time, use various types of financial instruments to reduce our exposure to fluctuating oil and natural gas prices, electricity costs, exchange rates and interest rates. The use of these financial
instruments exposes us to credit risks associated with the possible non-performance of counterparties to the derivative contracts. We limit this risk by executing counterparty risk procedures which include transacting only with financial
institutions who are members of our credit facility or those with high credit ratings as well as obtaining security in certain circumstances.

Goodwill

Goodwill is recorded on a business combination when the total purchase consideration exceeds the fair value of the net identifiable assets and liabilities
of the acquired entity. The goodwill balance is not amortized; however, it must be assessed for impairment at least annually. In 2013, we recorded a $48 million goodwill impairment charge related to a non-core play to which goodwill was associated.

Deferred Tax

Deferred taxes are recorded based on the
liability method of accounting whereby temporary differences are calculated assuming financial assets and liabilities will be settled at their carrying amount. Deferred taxes are computed on temporary differences using substantively enacted income
tax rates expected to apply when future income tax assets and liabilities are realized or settled.

Forward-Looking Statements

Certain statements contained in this document constitute forward-looking statements or information (collectively forward-looking statements) within
the meaning of the safe harbour provisions of applicable securities legislation. Forward-looking statements are typically identified by words such as anticipate, continue, estimate, expect,
forecast, budget, may, will, project, could, plan, intend, should, believe, outlook, objective,
aim, potential, target and similar words suggesting future events or future performance. In addition, statements relating to reserves or resources are deemed to be forward-looking
statements as they involve the implied assessment, based on certain estimates and assumptions, that the reserves and resources described exist in the quantities predicted or estimated and can be profitably produced in the future. In particular, this
document contains forward-looking statements pertaining to, without limitation, the following: under Business Strategy, our belief that our five-year plan positions us as a leading oil producer in the Western Canadian Sedimentary basin
and the key features of the long-term strategy, including the promotion of operational excellence across all levels of the Company, focusing our development activities on projects with the highest returns in three of our core areas (Cardium, Viking,
Slave Point), non-core asset rationalization including $1.5 to $2 billion of asset dispositions, debt reduction, continuing to drive cost reductions and a sustainable dividend strategy moving forward, our intention in 2014 to continue to focus on
the key strategies outlined in our long-term plan, and our expectation that we will close the recently announced $175 million disposition in the first quarter of 2014; under Crude Oil, our suggestion that the completion of certain
pipeline projects could ease current pipeline constraints out of Western Canada; under Natural Gas, our assertion that natural gas is not currently positioned to increase market share from coal in the power generation sector should power
demand increase; under Performance Indicators, our intention that in 2014 our development plans will emphasize the Cardium, Viking and Slave Point areas and increased application of waterflood programs, our plans for further non-core
asset dispositions as part of our strategy to increase the focus of our portfolio and strengthen our balance sheet, our belief that funds flow per share is an important measure to drive shareholder returns and that increases in this metric are
correlated to share price, our belief that dividends impose natural capital investment limits on management and thus may limit shareholder exposure to excessive operational and other risks, our expectation that our net debt to funds flow ratio will
improve in future years as we continue to de-lever our balance sheet and focus on light-oil, higher return projects, our intention as we move forward to focus development in three main light-oil areas (the Cardium, Slave Point and Viking), our
intention to focus on cost reduction to realize improvements in our netbacks which in turn drives higher funds flow, and our target for a 110 percent sustainability ratio in our long-term plan; under Environmental and Climate Change, our
dedication to reducing the environmental impact from our operations through our environmental programs and our intention to continuously monitor our operations to minimize the environmental impact thereof and to allocate sufficient capital to
reclamation and other activities to mitigate the impact on the areas in which we operate; under Liquidity and Capital Resources, the details of our first quarter dividend, the factors that could affect future cash dividend levels, and
our belief that our debt and risk management actions and plans may increase the likelihood of maintaining our financial flexibility to capture opportunities available in the markets in addition to the continuation of our capital and dividend
programs and hence the longer-term execution of our business strategies; under Outlook, our forecast 2014 annual and first quarter development capital expenditure budgets and 2014 average daily production volumes; and certain disclosures
contained under the heading Sensitivity Analysis relating to our estimated sensitivities to selected key assumptions on our future funds flow.

With respect to forward-looking statements contained in this document, we have made assumptions regarding, among other things: the terms and timing of asset
sales completed under our ongoing program to sell between $1.5 billion and $2.0 billion of non-core assets, including the asset sale anticipated to close in the first quarter of 2014; our ability to execute or long-term plan as described herein and
the impact that the successful execution of such plan will have on our Company and our shareholders; future crude oil, natural gas liquids and natural gas prices and differentials between light, medium and heavy oil prices and Canadian, WTI and
world oil and natural gas prices; future capital expenditure levels; future crude oil, natural gas liquids and natural gas production levels; drilling results; future exchange rates and interest rates; the amount of future cash dividends that we
intend to pay and the level of participation in our dividend reinvestment plan; our ability to obtain equipment in a timely manner to carry out development activities and the costs thereof; the stability of the regulatory environment in which we
operate and the likelihood of our obtaining regulatory approvals and of other regulatory outcomes; our ability to market our oil and natural gas successfully to current and new customers, including our ability to access rail, pipeline and other
transportation infrastructure; our ability to obtain financing on acceptable

terms, including our ability to renew or replace our credit facility and our ability to finance the repayment of our senior unsecured notes on maturity; and our ability to add production and
reserves through our development and exploitation activities. In addition, many of the forward-looking statements contained in this document are located proximate to assumptions that are specific to those forward-looking statements, and such
assumptions should be taken into account when reading such forward-looking statements: see in particular the assumptions identified under the headings Outlook and Sensitivity Analysis.

Although we believe that the expectations reflected in the forward-looking statements contained in this document, and the assumptions on which such
forward-looking statements are made, are reasonable, there can be no assurance that such expectations will prove to be correct. Readers are cautioned not to place undue reliance on forward-looking statements included in this document, as there can
be no assurance that the plans, intentions or expectations upon which the forward-looking statements are based will occur. By their nature, forward-looking statements involve numerous assumptions, known and unknown risks and uncertainties that
contribute to the possibility that the predictions, forecasts, projections and other forward-looking statements will not occur, which may cause our actual performance and financial results in future periods to differ materially from any estimates or
projections of future performance or results expressed or implied by such forward-looking statements. These risks and uncertainties include, among other things: the possibility that we are unable to execute some or all of our ongoing non-core asset
disposition program on favourable terms or at all, including the disposition discussed herein that is scheduled to close in the first quarter of 2014, whether due to the failure to receive requisite regulatory approvals or satisfy applicable closing
conditions or for other reasons that we cannot anticipate; the possibility that we will not be able to successfully execute our long-term plan in part or in full, and the possibility that some or all of the benefits that we anticipate will accrue to
our Company and our securityholders as a result of the successful execution of such plan do not materialize; the impact of weather conditions on seasonal demand and ability to execute capital programs; risks inherent in oil and natural gas
operations; uncertainties associated with estimating reserves and resources; competition for, among other things, capital, acquisitions of reserves, resources, undeveloped lands and skilled personnel; incorrect assessments of the value of
acquisitions; geological, technical, drilling and processing problems; general economic and political conditions in Canada, the U.S. and globally; industry conditions, including fluctuations in the price of oil and natural gas, price differentials
for crude oil and natural gas produced in Canada as compared to other markets and transportation restrictions, including pipeline and railway capacity constraints; royalties payable in respect of our oil and natural gas production and changes to
government royalty frameworks; changes in government regulation of the oil and natural gas industry, including environmental regulation; fluctuations in foreign exchange or interest rates; unanticipated operating events or environmental events that
can reduce production or cause production to be shut-in or delayed, including extreme cold during winter months, wild fires and flooding; failure to obtain regulatory, industry partner and other third-party consents and approvals when required,
including for acquisitions, dispositions and mergers; failure to realize the anticipated benefits of dispositions, acquisitions, joint ventures and partnerships, including those discussed herein; uncertainties regarding decisions and outcomes on oil
and natural gas facilities and other assets jointly owned with and in some cases operated by third parties; changes in tax and other laws that affect us and our securityholders; the potential failure of counterparties to honour their contractual
obligations; stock market volatility and market valuations; OPECs ability to control production and balance global supply and demand of crude oil at desired price levels; political uncertainty, including the risks of hostilities, in the
petroleum producing regions of the world; and the other factors described in our public filings (including our Annual Information Form) available in Canada at www.sedar.com and in the United States at www.sec.gov. Readers are cautioned that this
list of risk factors should not be construed as exhaustive.

The forward-looking statements contained in this document speak only as of the date of this
document. Except as expressly required by applicable securities laws, we do not undertake any obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. The
forward-looking statements contained in this document are expressly qualified by this cautionary statement.
