CALGARY, Alberta, February 24, 2011 /PRNewswire/ -- Perpetual Energy Inc. ("Perpetual" or the "Corporation") is pleased to release a supplemental independent reserve report for its Elmworth Montney asset prepared by GLJ Petroleum Consultants ("GLJ"). Based on the most current information, GLJ has recently prepared a report for the operator of this property and that report, when extrapolated to Perpetual's interests in the area, recognizes material reserves and value for Perpetual attributable to this asset. Perpetual engaged GLJ to prepare a reserve report (the "Supplemental Reserve Report") for the Elmworth property as a supplement to the Corporation's year-end reserve report provided by McDaniel and Associates Consultants Ltd. ("McDaniel") dated February 7, 2011. The following information highlights Perpetual's Elmworth Montney reserve assignments and restates Perpetual's 2010 year-end reserves.

ELMWORTH MONTNEY YEAR-END 2010 RESERVES

The Supplemental Reserve Report recognizes 14.5 Bcfe (2.4 MMboe) of proven and 32.1 Bcfe (5.3 MMboe) of proved and probable reserves to Perpetual's interest. Using the GLJ January 1, 2011 price forecast, the net present value of the reserves discounted at 8 percent is estimated at $14.7 million for proved reserves and $43.6 million for total proved and probable reserves net to Perpetual, including recovery of future development capital ("FDC"). These reserves had previously been classified by McDaniel and Associates Consultants Ltd. ("McDaniel") as contingent resources pending the definition of a development plan which was not available at the time their report was completed. Through an information swap with other nearby producers, the operator has since gathered the necessary data to build an economic development plan for the area. Perpetual has reviewed the development plan, and is in agreement with the assignment of reserves at this time. Based on the development plan, GLJ has assigned 20 to 25 bbls per MMcf of associated natural gas liquid (NGL) reserves to the Montney at Elmworth. Liquids recovery could be enhanced through a development plan that incorporated improved deep cut liquids recovery as test results indicate free condensate in the order of 20 to 25 bbls per MMcf and other entrained NGL's of an additional 20 to 40 bbls per MMcf which could potentially be recoverable depending on the liquids recovery process. GLJ estimates FDC required to convert the non-producing and undeveloped reserves to producing reserves at $45.1 million. This reserve assignment impacts only seven of the 42 sections of land that were assigned contingent resources by McDaniel, leaving 145 Bcfe (24.2 MMboe) of best estimate contingent resource, net to Perpetual, to be converted to reserves in the future.

RESTATEMENT OF YEAR-END 2010 RESERVES

The Corporation is pleased to release a revised summary of Perpetual's combined year-end 2010 reserves information, as evaluated by the independent engineering firms McDaniel and GLJ.

Year-End Reserve Highlights

    
    - In 2010, Perpetual added 72.1 Bcfe (12.0 MMboe) of proved and
      probable reserves, replacing 129% of its production (111% on a total
      proved basis).

    - After dispositions of 53.1 Bcfe (8.9 MMboe) and production of 55.9
      Bcfe (9.3 MMboe) in 2010, proved and probable reserves increased
      three percent from 471.6 Bcfe (78.6 MMboe) at year-end 2009 to 487.7
      Bcfe (81.3 MMboe) and proved reserves increased two percent to 250.4
      Bcfe (41.7 MMboe) at year-end 2010.

    - Excluding downward revisions related solely to changes in natural gas
      pricing at year-end 2010 of 22.3 Bcfe (3.7 MMboe), Perpetual's
      reserves grew eight percent year over year from 471.6 Bcfe (78.6
      MMboe) to 510.0 Bcfe (85.0 MMboe), offsetting production of 55.9 Bcfe
      (9.3 MMboe) and net dispositions of 9.8 Bcfe (1.6 MMboe), which
      included the disposition of 34.2 Bcf (5.7 MMboe) of probable shut-in
      gas over bitumen reserves where the effective cash flow through the
      Government of Alberta's financial solution was retained by Perpetual.

    - Reserve additions which offset production and dispositions were a
      result of total net capital spending of $163.2 million, including
      investment of $114.1 million in exploration and development capital
      spending programs excluding spending for the development of
      Perpetual's gas storage asset at Warwick ("Warwick Gas Storage"), as
      well as various asset acquisitions in the Edson and Birchwavy areas
      during the year.

    - Including changes in future development capital ("FDC"), Perpetual
      realized finding and development costs ("F&D") of $1.67 per Mcfe
      ($10.02 per BOE) on a proved and probable reserve basis in 2010. This
      results in a recycle ratio of 3.0 based on a 2010 estimated cash flow
      netback of $4.94 per Mcfe, which includes cash flow as a result of
      natural gas hedging gains, and 1.3 based on an estimated 2010 average
      cash flow netback of $2.24 per Mcfe, excluding natural gas hedges.
      Excluding changes in FDC, F&D in 2010 was $1.39 per Mcfe ($8.34 per
      BOE).

    - Perpetual's realized finding, development and acquisition costs
      ("FD&A"), including changes in FDC, was $2.15 per Mcfe ($12.90 per
      BOE) on a proved and probable basis. FD&A costs were significantly
      impacted by relatively low disposition metrics on a reserve basis
      associated with the sale of probable shut-in gas over bitumen
      reserves without the related effective funds flow from future royalty
      reductions in the Legend, Liege and Surmont areas of 34.2 Bcf (5.7
      MMboe) for net proceeds of $39.8 million. Perpetual retained the
      effective funds flow for these shut-in gas over bitumen reserves
      making the asset sales incomparable to other transactions, therefore
      the proceeds and reserves associated from these dispositions have
      been removed for purposes of the FD&A calculation. Excluding changes
      in FDC, FD&A in 2010 was $1.93 per Mcfe ($11.58 per BOE).

    - In addition to their year-end reserve assessment, McDaniel prepared
      an independent contingent resource assessment report (the "Contingent
      Resource Report") for the Montney formation in the Elmworth area.
      Giving consideration to the assignment of reserves in seven sections
      in the Elmworth area by GLJ, the McDaniel contingent resource report
      has been adjusted to reflect the assignment of reserves to seven of
      the 42 sections of land assigned contingent resource by McDaniel. The
      adjusted report assigns gross original gas in place ("OGIP") on 35
      sections of company interest lands of 809.4 Bcf plus associated NGLs.
      Assuming a range in recovery factors from 20 to 50 percent, gross
      recoverable sales gas is estimated from a low of 137.6 Bcf with 4.9
      MMbbls of NGLs (166.7 Bcfe, 27.8 MMboe) to a high of 344.0 Bcf with
      20.2 MMbbls NGLs (465.4 Bcfe, 77.6 MMboe), with McDaniel's best
      estimate at 35 percent recovery factor translating to 240.8 Bcf with
      11.3 MMbbls NGLs (308.8 Bcfe, 51.5 MMboe). On a working interest
      basis, the best estimate recoverable contingent resource is estimated
      at 145.0 Bcfe (24.2 MMboe). Perpetual has an additional 34 gross
      sections in the Elmworth area which have not yet been evaluated
      through drilling in the Montney formation and therefore have no
      contingent resource or reserves assigned as yet.

    - Perpetual's reserve to production ratio ("reserve life index" or
      "RLI") is 8.7 years on a proved and probable reserves basis (4.9
      years on a proved reserves basis) at year-end 2010.

    - Perpetual's reserve-based net asset value ("NAV") at year-end 2010 is
      estimated at $5.24 per Share discounted at eight percent.

Reserves Disclosure

Company interest reserves included herein are before royalty burdens and including royalty interests. Reserves information is based on independent reserves evaluation reports prepared by McDaniel dated February 7, 2011 (the "McDaniel Report"), and GLJ dated February 22, 2010 (the "GLJ Report") both with an effective date of December 31, 2010 and has been prepared in accordance with National Instrument 51-101 ("NI 51-101") using McDaniel's and GLJ's forecast prices and costs respectively. Complete NI 51-101 reserves disclosure including after-tax reserve values, reserves by major property and abandonment costs will be included in Perpetual's Annual Information Form ("AIF"), which will be filed in March 2011.

Approximately 94 percent of Perpetual's proved and proved and probable reserves are natural gas and as such the Corporation reports reserves in Mcf equivalent (Mcfe). Mcfe may be misleading, particularly if used in isolation. In accordance with NI 51-101 a Mcfe conversion ratio for oil of 1 Bbl: 6 Mcf has been used, which is based on an energy equivalency conversion method primarily applicable at the burner tip and does not necessarily represent a value equivalency at the wellhead.

    
    Perpetual's consolidated reserves at year-end 2010 are summarized below.

Perpetual retained the effective funds flow from the reduction of future royalties related to the financial solution in place for the shut-in gas and this is reflected in proved future net revenues.

Year over year, McDaniel recorded net positive technical revisions totaling 27.4 Bcfe (4.6 MMboe) on a proved and probable basis. These positive revisions were due to improved performance and improved operating costs in all areas. These positive revisions were offset by a substantially reduced price forecast at year-end 2010 relative to year-end 2009 resulting in negative revisions of 22.3 Bcfe (3.7 MMboe) due to increased economic limits which primarily affected the forecast for wells as they neared their end of productive life. Included in the downward price revisions are those future projects whose return on investment at the current price forecast results is negative.

The McDaniel price forecasts utilized in the evaluation of the majority of Perpetual's assets are summarized below.

NET PRESENT VALUE ("NPV") OF RESERVES SUMMARY

Perpetual's light and medium oil, natural gas and natural gas liquids reserves were evaluated by McDaniel and GLJ using McDaniel's product price forecast effective January 1, 2011 for all properties with the exception of Elmworth which was evaluated using GLJ's product price forecasts effective January 1, 2011, prior to provision for financial natural gas price hedges, income taxes, interest, debt service charges and general and administrative expenses. The following table summarizes the net present value of funds flows from recognized reserves at January 1, 2011, assuming various discount rates. It should not be assumed that the discounted future net funds flows estimated by McDaniel and GLJ represent the fair market value of the potential future production revenue of the company.

CONTINGENT RESOURCE

A resource assessment was conducted for the Montney Formation in the Elmworth area by McDaniel as at year-end 2010. Perpetual has adjusted the resource evaluation for the reserves recognized in the GLJ Supplemental Reserve Report, removing lands assigned reserves from the contingent resource evaluation, the results of which are summarized below.

    (1) Contingent resources have been evaluated by McDaniel using the
        definitions is as defined in section five of the Canadian Oil and Gas
        Evaluators Handbook, Volume 1. All volumes are reported before the
        deduction of royalties payable to others. Contingent resource
        assignments are in addition to any reserve assignments associated
        with these assets.

    (2) A Low estimate (90% chance the ultimate recoverable resource will be
        equal or greater than the stated value), means higher certainty, a
        Best estimate (50% chance that the ultimate recoverable resource will
        be greater than or equal to the stated value) means most likely and a
        High estimate means lower than a 50% chance that the ultimate
        recoverable resource will be greater than or equal to the stated
        value

    (3) McDaniel has assigned recovery factors of 20% (Low), 35% (Best) and
        50% (High) in their assessment of recoverable resource.

    (4) Contingent resources can be sub-classified into economic and
        uneconomic portions based on a number of assumptions on capital
        costs, timing, price forecast, etc. Currently sub-classification of
        these preliminary estimates has not been completed pending a
        discussion of the above parameters.

The primary contingencies identified for the Montney resource are infrastructure and access to market. Once further development plans are in place and as wells are drilled, it is expected that a further portion of these estimates would shift into proved and probable reserves subject to standard booking practices.

NET ASSET VALUE ("NAV")

The following net asset value table shows what is normally referred to as a "produce-out" NAV calculation under which the Corporation's reserves would be produced at forecast future prices and costs. The value is a snapshot in time and is based on various assumptions including commodity prices and foreign exchange rates that vary over time. It should not be assumed that the NAV represents the fair market value of Perpetual shares. The calculations below do not reflect the value of the Corporation's prospect inventory to the extent that the prospects are not recognized within the NI-51-101 compliant reserve assessment.

No reserves or contingent resources are yet assigned to any of Perpetual's heavy oil/bitumen projects in northeast Alberta. The incremental value of Perpetual's extensive prospect inventory for its game-changing opportunities in the Montney at Elmworth, Cardium light oil at Carrot Creek, Wilrich liquids-rich gas at Edson, the Colorado shallow shale gas in east central Alberta and the bitumen projects in northeast Alberta, above the amount which is currently recognized by McDaniel and GLJ, is captured only through the assessment of the fair market value of undeveloped land based on current land sale valuation parameters.

Of further note, the value of the Corporation's Warwick Gas Storage asset has been recorded at cost in the net asset value calculation below. The funding of the gas storage reservoir development in 2009 and 2010 as well as the facility construction, through both debt and the forward sale obligation related to WGSI's base cushion gas, offsets this value. Construction of the Warwick Gas Storage facility was completed in the fourth quarter of 2010 and withdrawal has now commenced on the preliminary test cycle which will be complete at the end of March 2011. Information gathered during the test cycle will define the developed working gas capacity of the storage reservoir at that time. This in turn will lead to a more comprehensive valuation of the asset.

ABANDONMENT AND RECLAMATION COSTS

In addition to the abandonment cost estimates provided by McDaniel and GLJ inclusive in their reserve assessment, Perpetual compiles annually a detailed internal estimate of the Corporation's total future asset retirement obligation based on net ownership interest in all wells, facilities and pipelines, including estimated costs to abandon the wells, facilities and pipelines and reclaim the sites, and the estimated timing of the costs to be incurred in future periods. Pursuant to this evaluation, the estimated value of Perpetual's future asset retirement obligations, net of the estimated salvage value of facilities and equipment and discounted at 8 percent is $74 million as at December 31, 2010. The McDaniel and GLJ reports includes an undiscounted amount of $84 million with respect to expected future well abandonment costs related specifically to proved and probable reserves and such amount is included in the values captioned "Total Proved and Probable Reserves" in the NPV of Funds Flow table (see "NET PRESENT VALUE ("NPV") OF RESERVES SUMMARY"). Of the total future well abandonment costs included in the McDaniel and GLJ reports an undiscounted amount of $56 million relates to Perpetual's developed reserves. The following table presents the estimated future asset retirement obligations and estimated net salvage values at various discount rates:

FINDING, DEVELOPMENT AND ACQUISITION ("FD&A") COSTS

Under NI 51-101, the methodology to be used to calculate FD&A costs includes incorporating changes in future development capital required to bring the proved undeveloped and probable reserves to production. For continuity, Perpetual has presented herein FD&A costs calculated both excluding and including FDC. Changes in forecast FDC occur annually as a result of development activities, acquisitions and disposition activities and capital cost estimates that reflect the independent evaluator's best estimate of what it will cost to bring the proved undeveloped and probable reserves on production.

The following table summarizes Perpetual's F&D costs as well as finding, development and acquisition costs, before and after the inclusion of changes in FDC. Finding and development costs, including changes in FDC were $1.67 per Mcfe ($10.02 per BOE) on a proved and probable basis in 2010. F&D costs, excluding changes in FDC were $1.39 per Mcfe ($8.34 per BOE) on a proved and probable basis in 2010.

The same metrics are presented below with the impact of the sale of probable shut-in gas over bitumen reserves in the Legend, Liege and Surmont areas removed, as the dispositions are not comparable to other acquisitions and dispositions since Perpetual retained the effective funds flow related to the Government of Alberta's gas over bitumen financial solution through royalty reductions associated with the shut-in properties. Including changes in FDC, FD&A costs were $2.15 per Mcfe ($12.90 per BOE) on a proved and probable basis. FD&A costs, excluding changes in FDC were $1.93 per Mcfe ($11.58 per BOE) on a proved and probable basis in 2010.

Perpetual has also summarized in the table below these same metrics with the effect of the price-related revisions removed. Perpetual believes that the majority of these reserves will return to the books with a recovery in natural gas prices as the technical merits for booking the reserves have not changed, only the economic circumstances. Excluding the effects of negative reserve revisions related to substantially lower forward gas prices, including changes in FDC, Perpetual's F&D costs were $1.31 per Mcfe ($7.86 per BOE) for proved and probable reserves and FD&A costs were $1.77 per Mcfe ($10.62 per BOE) in 2010 on a proved and probable basis.

    (6) "Mcfe" may be misleading, particularly if used in isolation. An Mcfe
        conversion ratio of 1 bbl: 6 Mcf is based on an energy equivalency
        conversion method primarily applicable at the burner tip and does not
        represent a value equivalency at the wellhead.

Asset Disposition

Perpetual is also pleased to announce the sale of a minor, non-core shallow gas property in northeast Alberta for $9.0 million. The effective date of this sale is December 1, 2010. At year end, Perpetual had 3.7 Bcfe (3.1 Bcf gas and 0.1 MMbbl oil) proved and probable reserves recorded for this asset. The production impact of this sale is 2 MMcfe per day.
