PART I

ITEM 1.  BUSINESS.

General

     PDC 2001-D LimitedPartnership ("the Partnership") is a limited partnership formed on December 31, 2001 pursuant to the West Virginia Uniform Limited Partnership Act.  PetroleumDevelopment Corporation ("PDC") serves as Managing General Partner ofthe Partnership.

     Since the commencement ofoperations on December 31, 2001, the Partnership has been engaged in onshore,domestic oil and natural gas exploration exclusively in the Rocky MountainRegion.  A total of 18 limited partners contributed initial capital of $750,000and a total of 1,149 additional general partners contributed initial capital of$23,668,322 and PDC (Managing General Partner) contributed $5,310,985 in capitalas a participant in accordance with contribution provisions of the LimitedPartnership Agreement (the Agreement). During 2002 in accordance with thePartnership Agreement, all Additional General Partners were converted toLimited Partners.

     Under the terms of theAgreement, the allocation of revenues is as follows:

|                                                | Allocation

of Revenues |
|------------------------------------------------|-------------------------|
| Additional General and

 Limited Partners | 80%                     |
| Managing General Partner                       | 20%                     |

     Operating and direct costsare allocated and charged to the additional general and limited partners andthe Managing General Partner in the same percentages as revenues areallocated.  Leasehold, drilling and completion costs, and equipment costs areborne 80% by the Additional General and Limited Partners and 20% by theManaging General Partner. See Footnote 4 of financial statements for a completedescription of the allocation of Partnership revenue and costs.

Employees

     The Partnership has no employees;however, PDC has approximately 120 employees, including 17 in finance and dataprocessing, 8 in administration, 12 in exploration and development, 78 inproduction and 5 in natural gas marketing.

Plan of Operations

     The Partnershipparticipated in the drilling of thirty-three gross (29.25 net) wells and willcontinue to operate and produce its thirty-three gross productive wells.  ThePartnership does not have unexpended initial capital and no additional drillingactivity is planned.

     See Item 2 herein forinformation concerning the Partnership's gas wells.

Markets for Oil and Gas

     The availability of amarket for any oil and gas produced from the operations of the Partnership willdepend upon a number of factors beyond the control of the Partnership whichcannot be accurately predicted.  These factors include the proximity of thePartnership wells to and the capacity of natural gas pipelines, theavailability and price of competitive fuels, fluctuations in seasonal supplyand demand, and government regulation of supply and demand created by itspricing and allocation restrictions.  Oversupplies of gas can be expected tooccur from time to time and may result in the Partnership's wells being shut-inor curtailed.  Increased imports of oil and natural gas have occurred and areexpected to continue. The effects of such imports could adversely impact themarket for domestic oil and natural gas. All oil and natural gas is sold undercontracts based on market sensitive indexes that vary from month to month. Nofixed price contracts are in place. The Partnership sold oil and natural gas toseveral entities of which three customers accounted for 22.0%, 55.5% and 22.5%of the Partnership's total oil and natural gas sales for the year ended December 31, 2004, and 26.9%, 52.5% and 19.4% for the year ended December 31,2003.

Derivatives and Hedging Activities

     The Managing General Partner, through itssubsidiary Riley Natural Gas, has been in the gas marketing business since1986. During that time period, the Managing General Partner has utilized andcontinues to utilize commodity basedderivative instruments as hedges to manage a portion of the Partnership'sexposure to price volatility stemming from natural gas production.  Theseinstruments consist of NYMEX-traded natural gas futures and option contractsfor eastern Colorado production, and CIG (Colorado Interstate Gas Index)-basedcontracts for other Colorado production and NYMEX traded oil futures and optioncontracts for Colorado oil production.  The contracts hedge committed andanticipated natural gas sales, generally forecasted to occur within a 24 monthperiod. The Managing General Partner does not hold or issue derivatives fortrading or speculative purposes and permits utilization of hedges only if thereis an underlying physical position.  See "Commodity Price Risk" under Item7A.

     Notwithstanding the measuretaken by the Managing General Partner to attempt to control price risk, thePartnership remains subject to price fluctuations for natural gas and oil soldin the spot market.  The Managing General Partner continues to evaluate thepotential for reducing these risks by entering into hedge transactions.  Inaddition, the Managing General Partner may also close out any portion of hedgesthat may exist from time to time.

Competition

     The Partnership competes inmarketing its gas and oil with numerous companies and individuals, many ofwhich have financial resources, staffs and facilities substantially greaterthan those of the Partnership or Petroleum Development Corporation.

State Regulations

     State regulatoryauthorities have established rules and regulations requiring permits for welloperations, reclamation bonds and reports concerning operations.  States alsohave statutes and regulations concerning the spacing of wells, environmentalmatters and conservation, and have established regulations concerning theunitization and pooling of oil and gas properties and maximum rates ofproduction from oil and gas wells. The Partnership believes it has complied inall material respects with applicable state regulations. The Partnership estimates it has spentapproximately $ 9,200, $10,900 and $146,300 in 2004, 2003 and 2002,respectively to comply with federal and state regulations.

Federal Regulations

     Regulation of LiquidHydrocarbons. Liquid hydrocarbons (including crude oil and natural gasliquids) were subject to federal price and allocation controls until January1981 when controls were effectively eliminated by executive order of thePresident.  As a result, to the extent the Partnership sells oil produced fromits properties, those sales are at unregulated market prices.

     Although it appearsunlikely under present circumstances that controls will be reimposed uponliquid hydrocarbons, it is possible Congress may enact such legislation at afuture date. 

     Natural Gas Regulation.   Sale of natural gas by the Partnership is subject to regulation ofproduction, transportation and pricing by governmental regulatory agencies. Generally, the regulatory agency in the state where a producing well is locatedregulates production activities and, in addition, the transportation of gassold intrastate.  The Federal Energy Regulatory Commission (FERC) regulates theoperation and cost of interstate pipeline operators who transport gas. Currently the price of gas sold by the Partnership is not regulated by anystate or federal agency.

     Proposed Regulation. Numerous proposals concerning energy are being considered by the United StatesCongress, various state legislatures and regulatory agencies.  The possibleoutcome and effect of these proposals cannot be accurately predicted.

     Environmental and SafetyRegulation.  The Partnership believes that it complies, in all materialrespects, with all legislation and regulations affecting its operations in thedrilling and production of oil and gas wells and the discharge of wastes.  Todate, compliance with such provisions and regulations has not had a materialeffect upon the Partnership's expenditures for capital equipment, itsoperations or its competitive position.  The cost of such compliance is notanticipated to be material in the future.

     The Partnership has notparticipated in any exploratory wells.  No additional drilling activity isplanned.

Production 

See "Management's Discussion and Analysis" onpage 5 for Partnership production. 

Reserves

See "Footnote 8" to the Partnership's financialstatements for information related to the Partnership's oil and gas reserves.

Productive Wells

     As outlined in the abovetable, the Partnership has a total of 33 gross productive wells (29.25 netwells) all of which are located in Colorado.

     A "productivewell" is a well producing, or capable of producing, oil and gas incommercial quantities.  For purposes of the above table, a "grosswell" is one in which the Partnership has a working interest and a"net well" is a gross well multiplied by the Partnership's workinginterest to which it is entitled under its drilling agreement.

Title to Properties

     The Partnership's interestsin producing acreage are in the form of assigned direct interests in leases.Such properties are subject to customary royalty interests generally contractedfor in connection with the acquisition of properties and could be subject toliens incident to operating agreements, liens for current taxes and otherburdens.  The Partnership believes that none of these burdens materiallyinterfere with the use of such properties in the operation of the Partnership'sbusiness.

     As is customary in the oiland gas industry, little or no investigation of title is made at the time ofacquisition of undeveloped properties (other than a preliminary review of localmineral records).  Investigations are generally made, including in most casesreceiving a title opinion of legal counsel, before commencement of drillingoperations.  A thorough examination of title has been made with respect to allof the Partnership's producing properties and the Partnership believes that ithas generally satisfactory title to such properties.

ITEM 3.  LEGAL PROCEEDINGS.

     The Managing Generalpartner as driller/operator is not party to any legal action that it believeswould have a materially adverse affect on the Managing General Partner's orPartnership's business, financial condition, results of operations orliquidity.

Results of Operations

2004 Results Compared to 2003 

     Oil and gas sales for the year ended December 31, 2004 were $3,749,528 compared to $4,898,005 for the year ended December 31, 2003.  For the year ended December 31, 2004, the Partnership sold 611,432 Mcfof gas and 21,707 barrels of oil at average sales prices of $4.80 and $37.83,respectively.  This compared with 953,208 Mcf of gas and 44,706 barrels of oilsold at average sales prices of $3.73 and $29.98, respectively for the yearended December 31, 2003. Lifting cost per Mcfe in 2004 amounted to $.87 ascompared to $0.74 for 2003. This increase is partially attributed to theincrease in severance and property taxes on the significantly higher oil andgas prices along with additional well work overs.  Depreciation, depletion and amortization decreased from $2,742,179 forthe year ended December 31, 2003 to $1,875,368 for the year ended December 31, 2004 as a result of lower volumes of natural gas and oil sold.  Cashdistributions to the partners amounted to $3,021,103 for 2004.

     

2003 Results Compared to 2002

     Oiland gas sales for the year ended December 31, 2003 were $4,898,005 compared to $2,986,031 for the year ended December 31, 2002.  For the year ended December 31, 2003, the Partnership sold 953,208 Mcf of gas and 44,706 barrels ofoil at average sales prices of $3.73 and $29.98, respectively.  This comparedwith 706,692 Mcf of gas and 53,295 barrels of oil sold at average sales pricesof $2.24 and $26.35, respectively for the year ended December 31, 2002. Lifting cost per Mcfe in 2003 amounted to $0.74 as compared to $0.46 for 2002.This increase is partially attributed to the increase in severance and propertytaxes. Depreciation, depletion andamortization increased from $2,283,603 for the year ended December 31, 2002 to $2,742,179 for the year ended December 31, 2003 as a result of higher volumes ofnatural gas and oil sold.  Cash distributions to the partners amountedto $4,246,871 for 2003.

     The Partnership's revenuesfrom oil and natural gas sales will be affected by changes in prices.  As aresult of changes in federal regulations, gas prices are highly dependent onthe balance between supply and demand. The Partnership's gas sales prices aresubject to increase and decrease based on various market sensitive indices.

     Certainaccounting policies are very important to the portrayal of the Partnership'sfinancial condition and results of operations and require management's mostsubjective or complex judgments. Inapplying those policies, our management uses its judgment to determine theappropriate assumptions to be used in the determination of certain estimates.Those estimates are based on our historical experience, our observance of trendsin the industry, and information available from other outside sources, asappropriate. For a more detailed discussion on the application of these andother accounting policies, see "Note 1 - Summary of significant accountpolicies" in our financial statements and related notes. The Partnership'scritical accounting policies and estimates are as follows:

Revenue Recognition

     Sales of natural gas are recognized whennatural gas has been delivered to a custody transfer point, persuasive evidenceof a sales arrangement exists, the rights and responsibility of ownership passto the purchaser upon delivery, collection of revenue from the sale isreasonably assured and the sales price is fixed or determinable.  Natural gasis sold by the Managing General Partner under contracts with terms ranging fromone month to three years.  Virtually all of the Managing General Partner'scontracts pricing provisions are tied to a market index, with certainadjustments based on, among other factors, whether a well delivers to agathering or transmission line, quality of natural gas and prevailing supplyand demand conditions, so that the price of the natural gas fluctuates toremain competitive with other available natural gas supplies.  As a result, thePartnership's revenues from the sale of natural gas will suffer if marketprices decline and benefit if they increase.  The Managing General Partnerbelieves that the pricing provisions of its natural gas contracts are customaryin the industry.

The Managing General Partner currentlyuses the "Net-Back" method of accounting for transportation arrangements ofnatural gas sales.  The Managing General Partner sells gas at the wellhead andcollects a price and recognizes revenues based on the wellhead sales pricesince transportation costs downstream of the wellhead are incurred by theManaging General Partner's customers and reflected in the wellhead price.

6

Sales of oil are recognized whenpersuasive evidence of a sales arrangement exists, the oil is verified as producedand is delivered in a stock tank, collection of revenue from the sale isreasonably assured and the sales price is determinable.  The Partnership iscurrently able to sell all the oil that it can produce under existing salescontracts with petroleum refiners and marketers.  The Partnership does notrefine any of its oil production.  The Partnership's crude oil production issold to purchasers at or near the Partnership's wells under short-term purchasecontracts at prices and in accordance with arrangements that are customary inthe oil industry.

Accounting forDerivative Contracts at Fair Value

     ThePartnership uses derivative instruments to manage its commodity and financialmarket risks. Accounting requirements for derivatives and hedging activitiesare complex; interpretation of these requirements by standard-setting bodies isongoing. 

     Derivativesare reported on the Balance Sheets at fair value. Changes in fair value ofderivatives that are not designated as accounting hedges are recorded inearnings. 

    Themeasurement of fair value is based on actively quoted market prices, ifavailable. Otherwise, the Partnership seeks indicative price information fromexternal sources, including broker quotes and industry publications. If pricinginformation from external sources is not available, measurement involvesjudgment and estimates. These estimates are based on valuation methodologiesconsidered appropriate by the Partnership's management. 

     Forindividual contracts, the use of different assumptions could have a materialeffect on the contract's estimated fair value. In addition, for hedges offorecasted transactions, the Partnership must estimate the expected future cashflows of the forecasted transactions, as well as evaluate the probability ofthe occurrence and timing of such transactions. Changes in conditions or theoccurrence of unforeseen events could affect the timing of recognition inearnings for changes in fair value of certain hedging derivatives.

Use of Estimates inLong-Lived Asset Impairment Testing

Impairmenttesting for long-lived assets and intangible assets with definite lives isrequired when circumstances indicate those assets may be impaired.  Inperforming the impairment test, the Partnership would estimate the future cashflows associated with individual assets or groups of assets.  Impairment mustbe recognized when the undiscounted estimated future cash flows are less thanthe related asset's carrying amount.  In those circumstances, the asset must bewritten down to its fair value, which, in the absence of market priceinformation, may be estimated as the present value of its expected future netcash flows, using an appropriate discount rate.  Although cash flow estimatesused by the Partnership are based on the relevant information available at thetime the estimates are made, estimates of future cash flows are, by nature,highly uncertain and may vary significantly from actual results.

Oil and Gas Properties 

     Explorationand development costs are accounted for by the successful efforts method.

     The Partnership assessesimpairment of capitalized costs of proved oil and gas properties by comparingnet capitalized costs to estimated undiscounted future net cash flows on afield-by-field basis using expected prices. Prices utilized in each year'scalculation for measurement purposes and expected costs are held constantthroughout the estimated life of the properties. If net capitalized costsexceed undiscounted future net cash flows, the measurement of impairment isbased on estimated fair value which would consider future discounted cashflows.

Property acquisitioncosts are capitalized when incurred.  Geological and geophysical costs anddelay rentals are expensed as incurred.  The costs of drilling exploratorywells are capitalized pending determination of whether the wells havediscovered economically producible reserves.  If reserves are not discovered,such costs are expensed as dry holes.  Development costs, including equipmentand intangible drilling costs related to both producing wells and developmentaldry holes, are capitalized.

Unproved propertiesor leases are written-off to expense when it is determined that they willexpire or be abandoned.

Costs of provedproperties, including leasehold acquisition, exploration and development costsand equipment, are depreciated or depleted by the unit-of-production methodbased on estimated proved developed oil and gas reserves.

7

Upon sale orretirement of complete fields of depreciable or depletable property, the bookvalue thereof, less proceeds or salvage value, is credited or charged toincome.  Upon sale of a partial unit of property, the proceeds are credited toaccumulated depreciation and depletion.

New Accounting Standards

      In June 2001, theFinancial Accounting Standard Board issued FASB No. 143, "Accounting forAsset Retirement Obligations" that requires entities to record the fairvalue of a liability for an asset retirement obligation in the period in whichit is incurred and a corresponding increase in the carrying amount of therelated long-lived asset. This statement is effective for fiscal yearsbeginning after June 15, 2002. The Partnership adopted FASB No. 143 on January 1, 2003 and recorded a net asset of $12,762 and a related liability of $14,240(using a 6% discount rate) and a cumulative effect of change in accountingprinciple on prior years of $1,478.

Item 7 A.  Quantitative and Qualitative Disclosure AboutMarket Risk.

Market-Sensitive Instruments and Risk Management

     The Partnership's primarymarket risk exposure is commodity price risk.  This exposure is discussed indetail below:

Commodity Price Risk

         The Managing General Partner utilizescommodity-based derivative instruments as hedges to manage a portion of itsexposure to price risk from its oil and natural gas sales.  These instrumentsconsist of CIG-based contracts traded by JP Morgan for Colorado production. These hedging arrangements have the effect of locking in for specified periods(at predetermined prices or ranges of prices) the prices the Managing GeneralPartner will receive for the volume to which the hedge relates.  As a result,while these hedging arrangements are structured to reduce Partnership's exposure to changes in price associated with thehedged commodity, they also limit the benefit the Partnership might otherwisehave received from price changes associated with the hedged commodity.  The Partnerships'spolicy prohibits the use of natural gas future and option contracts for speculativepurposes.

The maximum term over which the Partnership is hedgingexposure to the variability of cash flows for commodity price risk is 12months. 

The average CIG closing price for natural gas for theyears 2004, 2003 and 2002 was $5.17 per Mmbtu, $4.04 per Mmbtu and $1.97 per Mmbtu. Future near-term gas prices will be affected by various supply and demandfactors such as weather, government and environmental regulations and newdrilling activities within the industry.

Disclosure of Limitations

     As the information aboveincorporates only those exposures that exist at December 31, 2004, it does not consider those exposures or positions which could arise after that date. As aresult, the Partnership's ultimate realized gain or loss with respect tocommodity price fluctuations will depend on the exposures that arise during theperiod, the Partnership's hedging strategies at the time and commodity pricesat the time.

PDC2001-D Limited Partnership:

Wehave audited the accompanying balance sheets of PDC 2001-D Limited Partnership(a West Virginia limited partnership) as of December 31, 2004 and 2003, and the related statements of operations, partners' equity and comprehensiveincome (loss), and cash flows for each of the years in the three-year periodended December 31, 2004. These financial statements are the responsibility ofthe Partnership's management. Our responsibility is to express an opinion onthese financial statements based on our audits.

Weconducted our audits in accordance with the standards of the Public CompanyAccounting Oversight Board (United States).  Those standards require that weplan and perform the audit to obtain reasonable assurance about whether thefinancial statements are free of material misstatement.  An audit includesexamining, on a test basis, evidence supporting the amounts and disclosures inthe financial statements.  An audit also includes assessing the accountingprinciples used and significant estimates made by management, as well asevaluating the overall financial statement presentation.  We believe that ouraudits provide a reasonable basis for our opinion.

Inour opinion, the financial statements referred to above present fairly, in allmaterial respects, the financial position of PDC 2001-D Limited Partnership asof December 31, 2004 and 2003, and the results of its operations and its cashflows for each of the years in the three-year period ended December 31, 2004,in conformity with U.S. generally accepted accounting principles.

Asdiscussed in note 1 to the financial statements, the Partnership adopted theprovisions of Statement of Financial Accounting Standards No. 143, "Accountingfor Asset Retirement Obligations", in 2003.

Notes to FinancialStatements

December 31, 2004, 2003 and 2002

(1)    Summary of SignificantAccounting Policies

       PartnershipFinancial Statement Presentation Basis

The financialstatements include only those assets, liabilities and results of operations ofthe partners which relate to the business of PDC 2001-D Limited Partnership(the Partnership).  The statements do not include any assets, liabilities,revenues or expenses attributable to any of the partners' other activities.Petroleum Development Corporation ("PDC") serves as Managing GeneralPartner of the Partnership.

Oil and GasProperties

The Partnershipfollows the successful efforts method of accounting for the cost of exploringfor and developing oil and gas reserves.  Under this method, costs ofdevelopment wells, including equipment and intangible drilling costs related toboth producing wells and developmental dry holes, and successful exploratorywells are capitalized and amortized on an annual basis to operations by theunits-of-production method using estimated proved developed reserves determinedat December 31, 2004 and 2003 by the Managing General Partner's petroleumengineer and at December 31, 2002 by an independent petroleum engineer, Wright& Company, Inc.  If a determination is made that an exploratory well hasnot discovered economically producible reserves, then its costs are expensed asdry hole costs.

The Partnershipassesses impairment of capitalized costs of proved oil and gas properties bycomparing net capitalized costs to undiscounted future cash flows on afield-by-field basis using expected prices. Prices utilized in each year'scalculation for measurement purposes and expected costs are held constantthroughout the estimated life of the properties.  If net capitalized costsexceed undiscounted future net cash flows, the measurement of impairment isbased on estimated fair value which would consider future discounted cashflows.  

Revenue Recognition

Sales of natural gas are recognized whennatural gas has been delivered to a custody transfer point, persuasive evidenceof a sales arrangement exists, the rights and responsibility of ownership passto the purchaser upon delivery, collection of revenue from the sale isreasonably assured and the sales price is fixed or determinable.  Natural gasis sold by the Managing General Partner under contracts with terms ranging fromone month to three years.  Virtually all of the Managing General Partner'scontracts pricing provisions are tied to a market index, with certainadjustments based on, among other factors, whether a well delivers to agathering or transmission line, quality of natural gas and prevailing supplyand demand conditions, so that the price of the natural gas fluctuates toremain competitive with other available natural gas supplies.  As a result, thePartnership's revenues from the sale of natural gas will suffer if marketprices decline and benefit if they increase.  The Managing General Partnerbelieves that the pricing provisions of its natural gas contracts are customaryin the industry.

The Managing General Partner currentlyuses the "Net-Back" method of accounting for transportation arrangements ofnatural gas sales.  The Managing General Partner sells gas at the wellhead andcollects a price and recognizes revenues based on the wellhead sales pricesince transportation costs downstream of the wellhead are incurred by theManaging General Partner's customers and reflected in the wellhead price.

Sales of oil are recognized whenpersuasive evidence of a sales arrangement exists, the oil is verified asproduced and is delivered in a stock tank, collection of revenue from the saleis reasonably assured and the sales price is determinable.  The Partnership iscurrently able to sell all the oil that it can produce under existing salescontracts with petroleum refiners and marketers.  The Partnership does notrefine any of its oil production.  The Partnership's crude oil production issold to purchasers at or near the Partnership's wells under short-term purchasecontracts at prices and in accordance with arrangements that are customary inthe oil industry.

Notes to FinancialStatements

Income Taxes

Since the taxableincome or loss of the Partnership is reported in the separate tax returns ofthe partners, no provision has been made for income taxes on the Partnership'sbooks.

Under federal incometax laws, regulations and administrative rulings, certain types of transactionsmay be accorded varying interpretations. Accordingly, the Partnership's taxreturn and, consequently, individual tax returns of the partners may be changedto conform to the tax treatment resulting from a review by the Internal RevenueService.

 

Derivative FinancialInstruments

The Managing GeneralPartner utilizes commodity based derivative instruments as hedges to manage aportion of the Partnership's exposure to price volatility stemming from naturalgas production. These instruments consist of costless collars and optioncontracts traded on the CIG (Colorado Interstate Gas Index). The costlesscollars and option contracts hedge committed and anticipated natural gas salesgenerally forecasted to occur within a 24 month period. The Partnership doesnot hold or issue derivatives for trading or speculative purposes.

All derivatives arerecognized on the Partnership balance sheet at their fair value.  On the datethe derivative contract is entered into, the Managing General Partnerdesignates the derivative as either a hedge of a forecasted transaction or thevariability of cash flows to be received or paid related to a recognized assetor liability ("cash flow" hedge), or a non-hedging derivative. The ManagingGeneral Partner formally documents all relationships between hedging instrumentsand hedged items, as well as its risk-management objective and strategy forundertaking various hedge transactions. This process includes linking allderivatives that are designated as cash-flow hedges to specific firmcommitments. The Managing General Partner also formally assesses, both at thehedge's inception and on an ongoing basis, whether the derivatives that areused in hedging transactions are highly effective in offsetting changes in cashflows of hedged items.  When it is determined that a derivative is not highlyeffective as a hedge or that it has ceased to be a highly effective hedge, thePartnership discontinues hedge accounting prospectively.  No hedging activitieswere discontinued during 2004 or 2003.

Changes in fairvalue of a derivative that is highly effective and that is designated andqualifies as a cash-flow hedge are recorded in accumulated other comprehensiveincome (loss), until earnings are affected by the variability in cash flows ofthe designated hedged item. Changes in the fair value of non-hedgingderivatives are reported in current-period earnings. The Partnershipdiscontinues hedge accounting prospectively when it is determined that thederivative is no longer effective in offsetting changes in the cash flows ofthe hedged item, the derivative expires or is sold, terminated, or exercised.  Additionally,if the derivative is designated as a hedging instrument, because it is probablethat a forecasted transaction will not occur, or the Partnership determinesthat designation of the derivative as a hedging instrument is no longerappropriate, hedge accounting will be discontinued.

By using derivative financial instruments to hedge exposuresto changes in commodity prices, the Managing General Partner exposes thePartnership to credit risk. Credit risk is the failure of the counterparty toperform under the terms of the derivative contract. When the fair value of aderivative contract is positive, the counterparty owes the Partnership, whichcreates credit risk. The Managing General Partner minimizes the credit risk inderivative instruments by entering into transactions with high-qualitycounterparties.

Notes to FinancialStatements

 

 

Use of Estimates

The Partnership hasmade a number of estimates and assumptions relating to the reporting of assetsand liabilities and revenues and expenses and the disclosure of contingentassets and liabilities to prepare these financial statements in conformity withaccounting principles generally accepted.  Actual results could differ fromthose estimates. Estimates which are particularly significant to the financialstatements include estimates of oil and gas reserves and future cash flows fromoil and gas properties which are used in assessing impairment of long-livedassets.

New AccountingStandards

In June 2001, theFinancial Accounting Standard Board issued FASB No. 143, "Accounting forAsset Retirement Obligations" that requires entities to record the fair valueof a liability for an asset retirement obligation in the period in which it isincurred and a corresponding increase in the carrying amount of the relatedlong-lived asset. This statement is effective for fiscal years beginning after June 15, 2002. The Partnership adopted FASB No. 143 on January 1, 2003 and recorded a net asset of $12,762 and a related liability of $14,240 (using a 6% discountrate) and a cumulative effect of change in accounting principle on prior yearsof $1,478.

(2)    Organization

The Partnership wasorganized as a limited partnership on December 31, 2001, in accordance with the laws of the State of West Virginia for the purpose of engaging in the drilling,completion and operation of oil and gas development and exploratory wells inthe Rocky Mountain Region.

Purchasers ofpartnership units subscribed to and fully paid for 37.5 units of limitedpartner interest and 1,183.416 units of additional general partner interests at$20,000 per unit (Investor Partners). Petroleum Development Corporation hasbeen designated the Managing General Partner of the Partnership. Although costs,revenues and cash distributions allocable to the limited and additional generalpartners are shared pro rata based upon the amount of their subscriptions, includingthe Managing General Partner to the extent of its capital contributions, thereare significant differences in the federal income tax effects and liabilityassociated with these different types of units in the Partnership.

Upon completion ofthe drilling phase of the Partnership's wells, all additional general partnersunits are converted into units of limited partner interests and thereafterbecome limited partners of the Partnership.  Limited partners do not have anyrights to convert their units into units of additional general partnerinterests in the Partnership.

In accordance withthe terms of the Limited Partnership Agreement (the Agreement), the ManagingGeneral Partner manages all activities of the Partnership and acts as theintermediary for substantially all Partnership transactions.

(3)    Transactions with ManagingGeneral Partner and Affiliates

Pursuant to theauthorization contained in the Agreement, PDC receives fees for servicesrendered and reimbursement of certain expenses from the Partnership.  Seerespective drilling prospectus for further information regarding the Agreement.The following table presents compensation or reimbursements by the Partnershipto PDC or other related parties for years ended December 31, 2004, 2003 and December 31, 2002.

Notes to FinancialStatements

(6)  Theallocation of profits, losses and cash distributions of the Managing GeneralPartner might be increased, and the allocation of profits, losses, and cashdistributions of the Investor Partners might be decreased in the event that theManaging General Partner were to invest more than the Managing GeneralPartner's minimum required Capital Contribution to cover tangible equipment andlease costs. The Managing General Partner will pay for the Partnership's shareof all Leases and tangible well equipment. The entire Capital Contribution ofthe Investor Partners, after payment of brokerage commissions, due diligencereimbursement, and the Management Fee, was utilized to pay for intangibledrilling costs. In the event that the Intangible Drilling Costs exceed thefunds of the Investor Partners available for payment of 

Intangible DrillingCosts (herein "excess IDC"), a portion of the Capital Contribution ofthe ManagingGeneral Partner may be used to pay such excess IDC. If the cost ofLeases and tangible well equipment were to exceed the Managing GeneralPartner's Capital Contribution of 21-3/4% of the aggregate Capital Contributionof the Investor Partners, then the Managing General Partner will increase itsCapital Contribution to fund such additional capital requirements and the ManagingGeneral Partner's allocation of profits, losses, and cash distributions will beincreased to equal the percentage arrived at by dividing the CapitalContribution made by the Managing General Partner by the Capital Available forInvestment; the allocation of the Investor Partners will be decreasedaccordingly.

(7)  Inaccordance with the repurchase provision of the partnership prospectus, PDC mayrepurchase units from the investor partners, which is entirely voluntary on thepart of the partners.  During 2004 PDC purchased a total of 1 unit ofpartnership interest for a total ownership of 1 unit as of December 31, 2004 which represents a .08% ownership of the original Investor Partners share oflimited and additional general partnership units.  Therefore, costs andrevenues and distributions for these purchased units are allocated to PDC inaccordance with the Investor Partners allocation percentages disclosed in thistable.

(5)  Derivative Financial Instruments

The Managing GeneralPartner utilizes commodity-based derivative instruments as hedges to manage aportion of its exposure to price risk from its oil and natural gas sales andmarketing activities.  These instruments consist of CIG-based contracts tradedby JP Morgan for Colorado production.  These hedging arrangements have theeffect of locking in for specified periods (at predetermined prices or rangesof prices) the prices the Managing General Partner will receive for the volumeto which the hedge relates.  As a result, while these hedging arrangements arestructured to reduce Partnership's exposureto changes in price associated with the hedged commodity, they also limit thebenefit the Partnership might otherwise have received from price changesassociated with the hedged commodity.  The Partnerships's policy prohibits theuse of natural gas future and option contracts for speculative purposes.

 (7)    Income Taxes

As a result of thedifferences in the treatment of certain items for income tax purposes asopposed to financial reporting purposes, primarily depreciation, depletion andamortization of oil and gas properties and the recognition of intangibledrilling costs as an expense or capital item, the income tax basis of oil andgas properties differs from the basis used for financial reporting purposes. At December 31, 2004 and 2003, the income tax basis of the Partnership's oil andgas properties was $2,212,983 and $2,752,080, respectively.

(8)    Supplemental ReserveInformation (Unaudited)

Proved oil and gasreserves of the Partnership have been estimated at December 31, 2004 and 2003 by the Managing General Partner's petroleum engineers and at December 31, 2002 by an independent petroleum engineer, Wright & Company, Inc. These reserveshave been prepared in compliance with the Securities and Exchange Commissionrules based on year end prices. A copy of the reserve report has been madeavailable to all partners. All of the partnership's reserves are proveddeveloped. An analysis of the change in estimated quantities of proveddeveloped oil and gas reserves is shown below:

(9)  Standardized Measure of DiscountedFuture Net Cash Flows and Changes Therein Relating to Proved Oil

        andGas Reserves (Unaudited)

Summarizedin the following table is information for the Partnership with respect to thestandardized measure of discounted future net cash flows relating to proved oiland gas reserves.  Future cash inflows are computed by applying year-end pricesof oil and gas relating to the Partnership proved reserves to the year-endquantities of those reserves.  Future production, development, site restorationand abandonment costs are derived based on current costs assuming continuationof existing economic conditions.

It isnecessary to emphasize that the data presented should not be viewed asrepresenting the expected cash flow from, or current value of, existing provedreserves since the computations are based on a large number of estimates andarbitrary assumptions.  Reserve quantities cannot be measured with precisionand their estimation requires many judgmental determinations and frequentrevisions.  The required projection of production and related expenditures overtime requires further estimates with respect to pipeline availability, rates ofdemand and governmental control. Actual future prices and costs are likely tobe substantially different from the current prices and costs utilized in thecomputation of reported amounts.  Any analysis or evaluation of the reportedamounts should give specific recognition to the computational methods utilizedand the limitations inherent therein.
