## **Overview**

This Annual Report onForm 10-K for the year ended December 31, 2005, includes the financial statementsof PDC 2005-A Limited Partnership ("the Partnership") for the year endedDecember 31, 2005 and substantially allof the information for the quarters ended June 30, 2005 and September 30, 2005that would normally be contained in Quarterly Reports on Form 10-Q.  

Aspreviously reported in an update included in Form 12b-25 (Notification of LateFiling) filed with the SEC on March 31, 2006, the Managing General Partner hadsuspended filing financial reports pending the complete assessment of its Partnershipoil and gas property accounting and to correct potential errors related todepreciation, asset impairments, asset retirement obligations and hedgeaccounting.  As a result of this review of our accounting policies andpractices, we determined that the Partnership's previously filed financialstatements do not require restatement.

**ITEM 1.****  BUSINESS**

General

PDC2005-A Limited Partnership was organized as a limited partnership pursuant tothe West Virginia Uniform Limited Partnership Act for the purpose ofaggregating funds for the exploration and production of oil and natural gas. Business operations of the Partnership commenced on February 9,2005, upon the closing of the offering for the sale of partnership units.

Pursuantto a registration statement filed with the Securities and Exchange Commission,limited and general partnership interests were registered for an offering underthe PDC 2004-2006 Drilling Program for the formation of a series of limitedpartnerships.  PDC 2005-A Limited Partnership was formed with totalcapital contributions of $39,937,470 from limited partners and additionalgeneral partners (collectively, the "Investor Partners") and $8,829,000 incapital contributed by Petroleum Development Corporation ("PDC"), the ManagingGeneral Partner. Total funding of the Partnership was $48,766,470.  Thecapital contributions from the Investor Partners consisted of 1,996.87partnership units at a unit price of $20,000 each. After syndication costs of$4,022,407 and a one time management fee to the Managing General Partner of$599,062, the Partnership had available cash of $44,145,001 to commencePartnership activities for the drilling of natural gas and oil wells. During2006, all additional general partners were converted to limited partners underprovisions of the partnership agreement.

Under the terms of thepartnership agreement, the allocation of production revenues among the InvestorPartners and the Managing General Partner is as follows:

|                            |  Allocation  |
|---------------------------------|-------------------|
|                            |  of Revenues |
| Investor Partners          | 80%               |
| Managing General  Partner  | 20%               |

Operatingand direct costs are allocated and charged to the Investor Partners and theManaging General Partner in the same percentages as revenues areallocated.  See "Note 4 - Allocation of Partners' Interests" in the Notesto the Financial Statements for a complete description of the allocation of allPartnership revenues and costs.

DrillingActivities

Sinceits formation, the Partnership has been engaged in onshore, domestic oil andnatural gas exploration and production exclusively in the Rocky MountainRegion. The Partnership participated in the drilling of only developmentwells.  Due to natural gas being the predominant production, all wells areclassified as gas wells, although significant amounts of oil can be produced inassociation with the gas. The followingtable summarizes the Partnership's drilling activities during 2005 related toits 49 wells:

Asof December 31, 2005, completion of one well was delayed until the spring of2006 due to weather conditions restricting access to the well site.  As ofthe filing of this report, all 49 wells have been completed.  The 49 wellsin the table above are the only wells the Partnership will drill because all ofthe capital contributions provided by the partnership offering will have beenutilized upon completion of the remaining well. 

Additional informationconcerning the Partnership's gas wells is contained in "Item 2 - Properties"below.

Plan ofOperations

Under agreement with the Investor Partners, the ManagingGeneral Partner serves as operator for the drilling of the Partnership's wells andfor the production and sale of natural gas and oil from the wells. Once producing, the Partnership's wells will beproduced until they are depleted or until they are uneconomical toproduce.  PDC plans to recomplete the Codell formation in most of the wells in the WattenbergField after five or more years of production because these wells will usuallyhave experienced a significant decline in production in that time period. These Codell recompletionstypically increase the production rates and recoverable reserves.  Priorexperience of PDC and other producers with Codell recompletions has resulted in significant productionincreases for most wells, although not all recompletionshave been successful. The cost of a Codell recompletion is about one-third of the cost of a new well(currently about $180,000).  The Managing General Partner will arrange forcontractors to perform the work, the cost of which will be paid out of overallrevenues of the Partnership.  PDC will pay its proportionate share ofcosts based on the operating costs sharing ratios of the Partnership.

Employees

ThePartnership has no employees. Services to the Partnership are provided by PDC,which has a total of approximately 170 employees, including personnel inaccounting and finance, administration, engineering, geology, field operations,and natural gas marketing. 

Markets for Oil and Gas

Theavailability of a market for any oil and natural gas produced from theoperation of the Partnership's wells will depend upon a number of factorsbeyond the control of the Partnership which cannot be accuratelypredicted.  These factors include the proximity of the Partnership wellsto and the capacity of natural gas pipelines, the availability and price ofcompetitive fuels, fluctuations in seasonal supply and demand, and governmentregulation of supply and demand created by its pricing and allocationrestrictions.  Oversupplies of gas can be expected to occur from time totime and may result in the Partnership's wells being shut-in or productionbeing curtailed.  Increased imports of oil and natural gas have occurredand are expected to continue. The effects of such imports could adverselyimpact the market for domestic oil and natural gas. 

PDCutilizes the services of its wholly-owned subsidiary, Riley Natural Gas (RNG),in marketing the oil and natural gas produced from Partnership wells.  RNGhas been in the gas marketing business since 1986. All oil and natural gas issold under contracts based on market sensitive indexes that vary from month tomonth. No fixed price contracts are in place.  Purchase contracts for thesale of oil are cancelable on 30 days notice, whereas purchase contracts forthe sale of natural gas may range from spot market sales of short duration tocontracts with a term of a number of years and that may require the dedicationof the gas from a well for a period ranging up to the life of the well. PDC will not make any commitment of future production that does not primarilybenefit the Partnership.  RNG is entitled to charge reasonable fees forits services, including out-of-pocket costs, which will be equal to or lessthan fees charged to non-affiliated producers for similar services. ThePartnership sold its oil and natural gas to three customers during 2005, whichaccounted for 49%, 33% and 18% of the Partnership's total oil and natural gassales for the period.

Derivatives and HedgingActivities

Historically,PDC and RNG have utilized commodity based derivative instruments to manage aportion of the exposure to price volatility stemming from natural gas and crudeoil production.  In order to provide a more predictable cash flow stream,PDC expects to continue the use of derivative instruments, including thePartnership's production of natural gas and oil, and will enter into derivativecontracts on behalf of the Partnership.  PDC may use financial hedges, putoptions, call options, and other derivative instruments to offset variations inprices.  The contracts hedge committed and anticipated natural gas and oilsales generally forecasted to occur within the next two-year period. TheManaging General Partner does not hold or issue derivatives for trading orspeculative purposes and permits utilization of hedges only if there is anunderlying physical position.  See "Commodity Price Risk" under Item 7Abelow.

Competition

The Partnership competes in marketing its gas and oilwith numerous companies and individuals, many of which have financial resources,staffs and facilities substantially greater than those of the Partnership orPDC.

Governmental Regulations

Federal and state regulatory authorities haveestablished rules and regulations requiring permits for well operations,reclamation bonds and reports concerning operations.  States also havestatutes and regulations concerning the spacing of wells, environmental mattersand conservation, and have established regulations concerning the unitizationand pooling of oil and gas properties and maximum rates of production from oiland gas wells. 

Natural Gas Regulation. Sale of natural gas by the Partnership is subject to regulation of production,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 the operation and cost of interstate pipeline operators who transportgas.  Currently, the price of gas sold by the Partnership is not regulatedby any state or federal agency.

Environmental and SafetyRegulations.  The Partnership believes that it complies, inall material respects, with all legislation and regulations relating toenvironmental and safety matters in the drilling and production of oil and gaswells and the discharge of wastes.  Compliance with such provisions andregulations is significant during well development but has not had a materialeffect upon the Partnership's expenditures for capital equipment, itsoperations or its competitive position.  The cost of such compliance isnot anticipated to be material in the future.

ThePartnership believes it has complied in all material respects with applicablestate and federal regulations. The Partnership estimates it has spentapproximately $580,000 in 2005 to comply with federal and state regulations,primarily relating to environmental permitting and compliance.

**ITEM1A.****  RISKFACTORS**

In the course of its normalbusiness, the Partnership is subject to a number of risks that could adverselyimpact its business, operating results, financial condition, and cashdistributions.  The following risk factors should be considered carefullyin addition to the other information included in this report.

Drilling natural gas and oil wells isspeculative and may be unprofitable or result in the total loss of investment. The drilling and completionoperations undertaken by the Partnership for the development of natural gas andoil reserves are inherently speculative and involve a high degree of risk andthe possibility of a total loss of investment.  Drilling activities mayresult in unprofitable well operations, not only from non-productive wells, butalso from wells that do not produce natural gas or oil in sufficient quantitiesor quality to return a profit on the amounts expended.  Consequently,Partnership wells may not produce sufficient natural gas and oil for investorsto receive a profit or even to recover their initial investment.  Only oneof the prior Partnerships sponsored by PDC has, to date, generated cashdistributions in excess of investor subscriptions without tax savings. PDC cannot predict whether any prospect will produce commercial quantities ofnatural gas or oil.  PDC cannot predict the life and the ultimateproduction of any well, and the actual lives could differ from thoseanticipated.

The partnership units are notregistered, there will be no public market for the units, and as a result, anInvestor Partner may not be able to sell his or her units.  There is and will beno public market for the units nor will a public market develop for theunits.  Investor Partners may not be able to sell their Partnershipinterests or may be able to sell them only for less than fair marketvalue.  The offer and sale of units have not been, and will not in thefuture, be registered under the Securities Act or under any state securitieslaws.  Each purchaser of units has been required to represent that suchinvestor has purchased the units for his or her own account for investment andnot with a view to resale or distribution.  No transfer of a unit may bemade unless the transferee is a "qualified investor" and suchtransfer is registered under the Securities Act and applicable state securitieslaws, or an exemption therefrom is available. The Partnership may require that the transferor provide an opinion of legalcounsel stating that the transfer complies with all applicable securitieslaws.  A sale or transfer of units by an investor requires PDC's prior written consent.  For these and otherreasons, an investor must anticipate that he or she will have to hold his orher Partnership interests indefinitely and will not be able to liquidate his orher investment in the Partnership.  Consequently, an investor must be ableto bear the economic risk of investing in the Partnership for an indefiniteperiod of time.

The additional general partners willbe individually liable for Partnership obligations and liabilities that aroseprior to conversion to limited partners (which can occur only after thedrilling completion operations are finished) that are beyond the amount oftheir subscriptions, partnership assets, and the assets of the Managing GeneralPartner.  UnderWest Virginia law, the state in which the Partnership has organized, generalpartners of a limited partnership have unlimited liability with respect to thepartnership.  Therefore, the additional general partners of thePartnership will be liable individually and as a group for all obligations andliabilities of creditors and claimants, whether arising out of contract or tortor in the conduct of the Partnership's operations, until such time as the additionalgeneral partners are converted to limited partners.  Under the PartnershipAgreement, this conversion is not scheduled to occur until the drilling andcompletion operations are finished.  Irrespective of conversion, theadditional general partners will remain fully liable for obligations andliabilities that arose prior to conversion.  Investors as additionalgeneral partners may be liable for amounts in excess of their subscriptions,the assets of the Partnership, including insurance coverage, and the assets ofthe Managing General Partner.

The Partnership may retainPartnership revenues if needed for Partnership operations to fully develop thePartnership's wells; if full development of the Partnership's wells provescommercially unsuccessful, an investor might anticipate a reduction in cashdistributions.  ThePartnership intends to utilize substantially all available capital raised in the offering for the drilling and completion ofwells and will have only nominal funds available for Partnership purposes priorto the time of production from Partnership well operations.  In thefuture, PDC may wish to rework or recompletePartnership wells but PDC has not held money from the initial investment forthat future work.  There is no assurance that future development of thePartnership's wells will prove commercially successful and that thefurther-developed Partnership wells will generate sufficient funds fromproduction to increase distributions to the investors to cover revenuesretained.  If future development of the Partnership's wells is notcommercially successful, the use of funds retained from production revenuescould result in a reduction of cash distributions to the Investor Partners. 

Increases in prices of oil andnatural gas have increased the cost of drilling and development and may affectthe performance of the Partnership in both the short and long term.  In the current highprice environment, most oil and gas companies have increased their expendituresfor drilling new wells.  This has resulted in increased demand and highercost for leases, oilfield services and well equipment.  Because of thesehigher costs, the risk to the Partnership of decreased profitability fromfuture decreases in oil and natural gas prices is increased.

Reductions in prices of oil andnatural gas reduce the profitability of the Partnership's productionoperations.  Globaleconomic conditions, political conditions, and energy conservation have createdunstable prices.  Revenues of the Partnership are directly related tonatural gas and oil prices for which PDC cannot predict.  The prices fordomestic natural gas and oil production have varied substantially over time andby location, and are likely to remain extremely unstable.  Revenue from the sale of oil and natural gas increases when pricesfor these commodities increase and declines when prices decrease. These unpredictable price changes can occur rapidly and are not within thecontrol of the Partnership.  A decline in natural gas and/or oil priceswould result in lower revenues for the Partnership and a reduction of cashdistributions to the partners of the Partnership.

----

 

The high level of drilling activitycould result in an oversupply of natural gas on a regional or national level,resulting in much lower commodity prices.  Recently, the natural gas market has beencharacterized by excess demand compared to the supplies available, leading ingeneral to higher prices for natural gas.  The high level of drilling,combined with a reduction in demand resulting from higher prices, could resultin an oversupply of natural gas.  In the Rocky Mountain region, rapidgrowth of production and increasing supplies may result in lower prices andproduction curtailment due to limitations on available pipeline facilities or marketsnot developed to utilize or transport the new supplies.  In both cases,the result would probably be lower prices for the natural gas the Partnership produces, reduced profitability for the Partnership andreduced cash distributions to the Investor Partners.

Sufficient insurance coverage may notbe available for the Partnership, thereby increasing the risk of loss for theInvestor Partners. It is possible that some or all of the insurance coverage which the Partnershiphas available may become unavailable or prohibitively expensive.  In thatcase, PDC might elect to change the insurance coverage.  The additionalgeneral partners could be exposed to additional financial risk due to thereduced insurance coverage and due to the fact that additional general partnerswould continue to be individually liable for obligations and liabilities of thePartnership.  Investor Partners could be subject to greater risk of lossof their investment because less insurance would be available to protect thePartnership from casualty losses.  Moreover, should the Partnership's costof insurance become more expensive, the amount of cash distributions to theinvestors will be reduced.

Throughtheir involvement in Partnership and other non-partnership activities, theManaging General Partner and its affiliates have interests which conflict withthose of the Investor Partners; actions taken by the Managing General Partnerin furtherance of its own interests could result in the Partnership's beingless profitable and a reduction in cash distributions to the investors.  PDC'scontinued active participation in oil and natural gas activities for its ownaccount and on behalf of other partnerships organized or to be organized by PDCand the manner in which Partnership revenues are allocated create conflicts ofinterest with the Partnership.  PDC has interests which inherentlyconflict with the interests of the investor partners.  In operating thePartnership, the Managing General Partner and its affiliates could take actionswhich benefit themselves and which do not benefit the Partnership.  Theseactions could result in the Partnership's being less profitable.  In thatevent, an Investor Partner could anticipate a reduction of cash distributions.

The Partnership andother partnerships sponsored by the Managing General Partner may compete witheach other for prospects, equipment, contractors, and personnel; as a result,the Partnership may find it more difficult to operate effectively andprofitably.  Duringand after 2006, PDC plans to offer interests in other partnerships to be formedfor substantially the same purposes as those of the Partnership. Therefore, a number of partnerships with unexpended capital funds, includingthose partnerships formed before and after the Partnership, may exist at thesame time.  The Partnership may compete for equipment, contractors, andPDC personnel (when the Partnership is also needful of equipment, contractorsand PDC personnel), which may make it more difficult and more costly to obtainservices for the Partnership.  In that event, it is possible that thePartnership would be less profitable.  Additionally, because PDC mustdivide its attention in the management of its own affairs as well as theaffairs of the 74 other limited partnerships PDC has organized, the Partnershipwill not receive PDC's full attention and efforts atall times.

The Partnership's derivativeactivities could result in reduced revenue compared to the level thePartnership might experience if no derivative instruments were in place.  The Partnership expectsto use derivative instruments to reduce the impact of price movements onrevenue.  While these derivative instruments protect the Partnershipagainst the impact of declining prices, they also may limit the positive impactof price increases.  As a result, the Partnership may have lower revenueswhen prices are increasing than might otherwise be the case, and may alsoreduce the Partnership's cash flows and cash distributions to the InvestorPartners.

Hedging transactions have in the pastand may in the future impact our cash flow from operations.  Our commodityhedging may prevent us from benefiting fully from price increases and mayexpose us to other risks. PDC will enter into hedging arrangements to reduce the Partnership's exposureto fluctuations in natural gas and crude oil prices and to achieve morepredictable cash flow.  Although the Partnership's hedging activities maylimit the Partnership's exposure to declines in natural gas and crude oilprices, these activities may also limit and have in the past limited,additional revenues from increases in natural gas and crude oil prices. To the extent that the Partnership engages in hedging activities to protectitself from commodity price volatility, the Partnership may be prevented fromrealizing the benefits of price increases above the levels of the hedges.

----

Additionally, the hedging transactions PDC has enteredinto, or will enter into, may not adequately protect the Partnership fromfinancial loss due to circumstances such as:

•        Highly volatile natural gas andcrude oil prices;

•        Production beingless than expected; or

•        A counterparty defaults on itscontractual obligations.

A significantfinancial loss by the Managing General Partner could result in PDC's inability to indemnify additional general partnersfor personal losses suffered because of Partnership liabilities.  As a result of PDC's commitments as Managing General Partner of severalpartnerships and because of the unlimited liability of a general partner tothird parties, PDC's net worth is at risk ofreduction if PDC suffers a significant financial loss.  Because PDC isprimarily responsible for the conduct of the Partnership's affairs as well asthe affairs of other partnerships for which PDC serves as managing generalpartner, a significant adverse financial reversal for PDC could result in PDC's inability to pay for Partnership liabilities andobligations.  The additional general partners of the Partnership might bepersonally liable for payments of the Partnership's liabilities andobligations.  Therefore, the Managing General Partner's financialincapacity could increase the risk of personal liability as an additionalgeneral partner because PDC would be unable to indemnify the additional generalpartners for any personal losses they suffered arising from Partnershipoperations.

The Managing General Partnermay not have sufficient funds or budget to repurchase limited partnershipunits.  As a result of the Managing General Partner being a generalpartner in several partnerships, the Partnership's net worth is at risk ofreduction if PDC suffers a significant financial loss.  Because theinvestors may request the Managing General Partner to repurchase the units inthe Partnership, subject to certain conditions and restrictions, a significantadverse financial reversal could result in the Managing General Partner'sinability to pay for Partnership obligations or the repurchase of investorunits.  

Fluctuating marketconditions and government regulations may cause a decline in the profitabilityof the Partnership.  The sale of any natural gas and oil produced bythe Partnership will be affected by fluctuating market conditions andgovernmental regulations, including environmental and safety standards set bystate and federal agencies.  From time-to-time, a surplus of natural gasor oil may occur in areas of the United States.  The effect of a surplusmay be to reduce the price the Partnership receives for the natural gas or oilproduction, or to reduce the amount of natural gas or oil that the Partnershipmay produce and sell.  As a result, the Partnership may not beprofitable.  Lower prices and/or lower production and sales will result inlower revenues for the Partnership and a reduction in cash distributions to thepartners of the Partnership.

Environmental hazards involved indrilling natural gas and oil wells may result in substantial liabilities forthe Partnership. There are numerous natural hazards involved in the drilling of wells, includingunexpected or unusual formations, pressures, blowouts involving possibledamages to property and third parties, surface damages, personal injury or lossof life, damage to and loss of equipment, reservoir damage and loss ofreserves.  Uninsured liabilities would reduce the funds available to thePartnership, may result in the loss of Partnership properties, and may createliability for additional general partners.  The Partnership may becomesubject to liability for pollution, abuses of the environment and other similardamages and insurance coverage may be insufficient to protect the Partnershipagainst all potential losses.  In that event, Partnership assets would beused to pay personal injury and property damage claims and the costs ofcontrolling blowouts or replacing destroyed equipment rather than for drillingactivities.  These payments would cause an otherwise profitablepartnership to be less profitable or unprofitable and would result in areduction of cash distributions to the partners of the Partnership.

Informationconcerning our reserves and future net revenues estimates is inherentlyuncertain.  The accuracy of proved reserves estimates andestimated future net revenues from such reserves is a function of the qualityof available geological, geophysical, engineering and economic data and issubject to various assumptions, including assumptions required by the SECrelating to oil and gas prices, drilling and operating expenses, and othermatters. Although we believe that our estimated proved reserves representreserves that we are reasonably certain to recover, actual future production,oil and gas prices, revenues, taxes, development expenditures, operating expensesand quantities of recoverable oil and gas reserves will most likely vary fromthe assumptions and estimates used to determine proved reserves. Anysignificant variance could materially affect the estimated quantities and valueof our oil and gas reserves, which in turn could adversely affect our cashflow, results of operations and the availability of capital resources. Inaddition, we may adjust estimates of proved reserves to reflect productionhistory, results of exploration and development, prevailing oil and gas pricesand other factors, many of which are beyond our control. Downward adjustmentsto our estimated proved reserves could require us to write down the carryingvalue of our oil and gas properties, which would reduce our earnings and ourpartners' equity.

Thepresent value of proved reserves will not necessarily equal the current fairmarket value of our estimated oil and gas reserves. In accordance with thereserve reporting requirements of the SEC, the estimated discounted future net cash flows from proved reserves arebased on prices and costs as of the date of the estimate. Actual future pricesand costs may be materially higher or lower than those as of the date of theestimate. The timing of both the production and the expenses with respect tothe development and production of oil and gas properties will affect the timingof future net cash flows from proved reserves and their present value.

Seasonalweather conditions may adversely affect the Partnership's ability to conductdrilling, completion and production activities in some of the areas where weoperate.  Oil and natural gasoperations in the Rocky Mountains are adversely affected by seasonal weatherconditions. In certain areas, drilling and other oil and natural gas activitiesare restricted or prevented by weather conditions for up to 6 months out of theyear. This limits operations in those areas and can intensify competitionduring those months for drilling rigs, oil field equipment, services, suppliesand qualified personnel, which may lead to periodic shortages. Theseconstraints and the resulting shortages or high costs could delay operationsand materially increase operating and capital costs and therefore, adverselyaffect profitability. 

**ITEM1B.****  UNRESOLVEDSTAFF COMMENTS**

None.

**ITEM2.****  PROPERTIES**

The Partnership's properties consist ofoil and gas wells, associated well equipment, and the ownership in leaseholdacreage assigned to the spacing units on which the 49 wells were drilled. The Partnership has no undeveloped acreage.

Drilling Activity

The Partnership commenced drilling activities on March 5, 2005, followingfunding of the Partnership, and as of December 31, 2005, all wells had beencompleted except for one well that was in progress at year end.  All ofthe Partnership's wells are located in Colorado. The following table sets forththe results of the Partnership's drilling activity as of December 31,2005.

Asof the date of this report, all 49 of the total wells drilled by thePartnership are considered productive wells.  The Partnership did notparticipate in the drilling of any exploratory wells. The one well in progressat year end was drilled in late 2005, but the completion was delayed until thespring of 2006 due to weather conditions restricting access to the well site. The 49 wells in the table above are the only wells to be drilled by thePartnership since all of the funds raised in the Partnership offering of$44,145,001 will have been utilized upon the completion of the one remainingwell.  

Adevelopment well is a well that is drilled close to and into the same formationas wells which have already produced and sold oil ornatural gas.  An exploratory well is one which is drilled in an area wherethere has been no oil or natural gas production, or a well which is drilled toa previously untested or non-producing zone in an area where there are wellsproducing from other formations.  Productive wells consist of producingwells and wells capable of producing oil and gas in commercial quantities,including gas wells awaiting pipeline connections to commence deliveries. A gross well refers to the number of wells in which the Partnership has aninterest.  A net well refers to a gross well multiplied by the percentageworking interest in the wells owned by the Partnership.

Reserves

See"Note 7 - Supplemental Reserve Information (Unaudited)"in the Financial Statements for information related to the Partnership's oiland gas reserves as of December 31, 2005.

### Production

See "Item 7 - Management's Discussion and Analysis andResults of Operations" below for information related to volumes, prices andproduction costs. 

Title to Properties 

The Partnership's interests in producing acreage are inthe form of assigned direct interests in leases. Such properties are subject tocustomary royalty interests generally contracted for in connection with theacquisition of properties and could be subject to liens incident to operatingagreements, liens for current taxes, and other burdens.  The Partnershipbelieves that none of these burdens materially interfere with the use of suchproperties in the operation of the Partnership's business.

Asis customary in the oil and gas industry, little or no investigation of titleis made at the time of acquisition of undeveloped properties (other than apreliminary review of local mineral records).  Investigations aregenerally made, including in most cases receiving a title opinion of legalcounsel, before commencement of drilling operations.  A thoroughexamination of title has been made with respect to all of the Partnership'sproducing properties and the Partnership believes that it has satisfactorytitle to such properties.

**ITEM3.****  LEGALPROCEEDINGS**

The Registrant is not a party to any legal proceedings.

PDC, as Managing General Partner and operator of thePartnership's wells, may be subject to various legal proceedings from time totime arising in the normal course of business.  Any outstanding andpending legal actions are not considered material to the operations of thePartnership or PDC.

**ITEM4.****  SUBMISSIONOF MATTERS TO A VOTE OF SECURITY HOLDERS**

None.

**PART II**

**ITEM 5.**** MARKET FOR REGISTRANT'S COMMON EQUITY ANDRELATED STOCKHOLDER MATTERS**

AtDecember 31, 2005, the Partnership had one Managing General Partner and 1,523Investor Partners holding a total of 1,996.87 units.  No establishedpublic trading market exists for the interests, nor will a public tradingmarket ever develop for the interests.  Limited and additional generalpartnership interests are transferable, however noassignee of an interest in the Partnership can become a substituted partnerwithout the written consent of the transferor and the Managing General Partner.

**ITEM7.****MANAGEMENT'S DISCUSSIONAND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

Safe Harbor Statement Under the Private SecuritiesLitigation Reform Act of 1995

Statements, other than historical facts, contained inthis Annual Report on Form 10-K, including statements of estimated oil and gasproduction and reserves, future cash flows and the Partnership's strategies,plans and objectives, are "forward-looking statements" within the meaning ofSection 27A of the Securities Act of 1933, as amended (the "Securities Act"),and Section 21E of the Securities Exchange Act of 1934, as amended (the"Exchange Act").  Although the Partnership believes that its forwardlooking statements are based on reasonable assumptions, it cautions that suchstatements are subject to a wide range of risks, trends and uncertainties,incidental to the production and marketing of oil and gas that could causeactual results to differ materially from those projected.  Among thoserisks, trends and uncertainties are important factors that could cause actualresults to differ materially from the forward looking statements, including,but not limited to, changes in production volumes, worldwide demand andcommodity prices for petroleum natural resources; risks incidental to theoperation of oil and gas wells; future production and development costs; theeffect of existing and future laws, governmental regulations and the politicaland economic climate of the United States; the effect of derivative activities;and conditions in the capital markets.  In particular, carefulconsideration should be given to cautionary statements made in this Form 10-Kand in the various reports the Partnership has filed with the Securities andExchange Commission.  The Partnership undertakes no duty to update or revisethese forward-looking statements.

Whenused in this Form 10-K, the words, "expect," "anticipate," "intend," "plan,""believe," "seek," "estimate" and similar expressions are intended to identifyforward-looking statements, although not all forward-looking statements containthese identifying words. Because these forward-looking statements involve risksand uncertainties, actual results could differ materially from those expressedor implied by these forward-looking statements for a number of important reasons,including those discussed under "Item 1A - Risk Factors"  and elsewhere inthis Form 10-K.

Thedrilling of oil and gas wells on prospects evaluated and designated by PDCcommenced on March 5, 2005. Forty-nine wells have been drilled, and as ofDecember 31, 2005, forty-eight wells have been completed and are producing. Thecompletion work on one of the wells drilled in 2005 has been delayed until thespring of 2006 due to weather conditions restricting access to the well site.The Managing General Partner anticipates that the remaining uncompleted wellwill be commercially productive upon completion.  The Partnership drilledonly development wells and did not participate in the drilling of exploratorywells.  No additional wells will be drilled by the Partnership.  Thetable in "Item 1 - Business" above summarizes the Partnership's drillingactivity during 2005.

Initial production from the Partnership wells commencedduring the second quarter of 2005, as wells were drilled, completed andconnected to pipelines. Sales of natural gas and oil from the Partnership'swells increased steadily during 2005 as additional wells were completed andplaced into production.  The last well to commence production during theyear occurred in the fourth quarter.  The table below reflects theproduction volumes, net to the Partnership, for each of the quarters in 2005.

The Partnership's future revenues from oil and naturalgas sales will be affected by changes in prices.  As a result of changesin market conditions, gas prices are highly dependent on the balance betweensupply and demand. The Partnership's sales prices for natural gas and oil aresubject to increases and decreases based on various market sensitive indices.

Interest income was earned by the Partnership during2005 on bank balances that existed while awaiting capital expenditures on thedrilling of the remaining oil and gas wells.

In accordance with the Partnership Agreement, aone-time management fee equal to 11⁄2% of investors' subscriptions, or $599,062,was paid by the Partnership to the Managing General Partner upon funding of thePartnership.

Thenet loss of $181,625 from oil and gas price risk management is comprised of thechange in fair value of oil and natural gas derivatives related to thePartnership's oil and gas production for derivative contracts entered into onbehalf of the Partnership by the Managing General Partner.  ThePartnership views these transactions as a gain or loss on financial instrumentsand not a part of oil and gas sales.

Liquidity and Capital Resources

The Partnership had a working capital balance at December31, 2005, of $5,745,650, which was primarily the result of receivables from oiland gas sales during the fourth quarter. Future operations are expected to beconducted with available funds and revenues generated from oil and gasproduction activities.  As of the date of this report, the Partnership has substantially finished the drilling and completionof its 49 wells and all partner contributions will have been utilized in thisprocess.  Other than the planned futurerecompletions in the Codellformation, there is no provision in the Partnership Agreement foradditional development or exploration beyond these 49 wells and there are nopresent capital needs of the Partnership. Current production revenues exceedoperating costs by a wide margin. However, PDC plans to recompletethe Codell formation in most of the 36 wells in theWattenberg Field after five years or more of production. These Codell recompletions typically increase the production rates andrecoverable reserves.  Prior experience of PDC and other producers with Codell recompletions has resultedin significant production increases for most wells, although not all recompletions have been successful.  The costof a Codell recompletion isabout one-third of the cost of a new well (currently about $180,000 for the recompletion). The Partnership is not permitted to borrowunder the Partnership Agreement; therefore, the cost of the recompletionswill be paid out of overall revenues of the Partnership.  The ManagingGeneral Partner is allowed to and may withhold production revenues in advanceof recompletion work.  This would reduce cashdistributions to the partners at the time of the recompletions,but should result in additional cash distributions following the recompletions.

Oiland Gas Reserves

Provedoil and gas reserves of the Partnership have been estimated at December 31,2005, to include 690,000 barrels of oil and 15,197,000 Mcfsof natural gas.  See "Note 7 - Supplemental Reserve Information (Unaudited)" in the Financial Statements for additionalreserve information.

Management'sDiscussion and Analysis- Three Months Ended June 30, 2005

*Resultsof Operation -*During the**quarter,the Partnership had net income of $615,697 resulting from the commencement ofproduction of oil and gas.  Production commenced as wells were drilled,completed and connected to a pipeline.  During the quarter 26 wells beganproducing. Total production for the Partnership during the quarter was 42,005 Mcf of gas and 20,562 barrels of oil. The results includednet losses related to oil and gas price risk management of $111,304 whichincluded an unrealized loss of $67,976 and a realized loss of $43,328. The Partnership's strategy in its derivative policy is to provide protection ondeclining oil and natural gas prices.  During this period of rising oiland natural gas prices, the Partnership recorded losses as market pricesexceeded contract prices related to the Partnership's oil and gas sales. The Partnership made no partner cash distributions during the quarter.

Management'sDiscussion and Analysis- Three Months Ended September 30, 2005

*Resultsof Operation -*During the**quarter,the Partnership had net income of $1,477,379 as more wells commenced productionof oil and gas.  During the quarter, 14 wells began producing and anadditional 8 wells were drilled, completed but not yet connected to apipeline.   Only one well remained to be drilled at September 30,2005, to complete the Partnership's drilling program.  Total productionfor the Partnership during the quarter was 185,654 Mcfof gas and 45,694 barrels of oil. The results included net losses related tooil and gas price risk management of $10,067 which included an unrealized gainof $24,105 and a realized loss of $34,172.  The Partnership's strategy inits derivative policy is to provide protection on declining oil and natural gasprices.  During periods of rising oil and natural gas prices, thePartnership may recorded losses as market prices exceed contract prices relatedto the Partnership's derivatives.  In periods of declining prices, thePartnership may record gains in its derivative transactions.  Partnershiprevenue is affected by changes in oil and natural gas prices.

ThePartnership distributed $1,079,425 to partners during the quarter.

# Critical Accounting Policies and Estimates

Wehave identified the following policies as critical to the understanding of theresults of operations. This is not a comprehensive list of all of ouraccounting policies. In many cases, the accounting treatment of a particulartransaction is specifically dictated by accounting principles generallyaccepted in the United States, with no need for management's judgment in theirapplication. There are also areas in which management's judgment in selectingany available alternative would not produce a materially different result.However, certain accounting policies are important to the portrayal of thePartnership's financial condition and results of operations and requiremanagement's most subjective or complex judgments. In applying those policies,management uses its judgment to determine the appropriate assumptions to beused in the determination of certain estimates. Those estimates are based onour historical experience, our observance of trends in the industry, andinformation available from other outside sources, as appropriate. For a moredetailed discussion on the application of these and other accounting policies,see "Note 2 - Summary of Significant Accounting Policies" and other relatednotes in the Financial Statements. The Partnership's critical accountingpolicies and estimates are as follows:

Oiland Gas Properties 

The Partnership accounts for its oil and gas propertiesunder the successful efforts method of accounting.  Costs of proveddeveloped producing properties, successful exploratory wells and developmentdry hole costs are depreciated or depleted by the unit-of-production methodbased on estimated proved developed producing oil and gas reserves. Property acquisition costs are depreciated or depleted on theunit-of-production method based on estimated proved oil and gas reserves. The Partnership obtains new reserve reports from independent petroleumengineers annually as of December 31st of each year.  The Partnershipadjusts for any major acquisitions, new drilling and divestures during the yearas needed.  The Partnership does not maintain an inventory of undrilled leases.

Upon sale or retirement ofsignificant or entire portions of fields of depreciable or depletableproperty, the book value thereof, less proceeds, is credited or charged toincome.  Upon sale of a partial unit of property, the proceeds arecredited to accumulated depreciation and depletion.

Useof Estimates in Testing for Impairment in Long-Lived Assets

Impairment testing for long-livedassets is required when circumstances indicate those assets may beimpaired.  The Partnership assesses impairment of capitalized costs ofproved oil and gas properties by comparing net capitalized costs to theestimated undiscounted future net cash flows on a field-by-field basis usingestimated production and based upon prices at which management reasonablyestimates such products will be sold. These estimates of future product pricesmay differ from current market prices of oil and gas. Any downward revisions tothe Partnership's estimates of future production or product prices could resultin an impairment of the Partnership's oil and gas properties in subsequentperiods. If net capitalized costs exceed undiscounted future net cash flows,the measurement of impairment is based on estimated fair value calculated usingfuture discounted cash flows.

RevenueRecognition

Salesof natural gas are recognized when natural gas has been delivered to a custodytransfer point, persuasive evidence of a sales arrangement exists, the rightsand responsibility of ownership pass to the purchaser, collection of revenuefrom the sale is reasonably assured, and the sales price is fixed ordeterminable.  Natural gas is sold by the Managing General Partner undercontracts with terms ranging from one month up to the life of the well. Virtually all of the Managing General Partner's contracts' pricing provisionsare tied to a market index with certain adjustments based on, among otherfactors, whether a well delivers to a gathering or transmission line, qualityof natural gas and prevailing supply and demand conditions, so that the priceof the natural gas fluctuates to remain competitive with other availablenatural gas supplies.  As a result, the Partnership's revenues from thesale of natural gas will suffer if market prices decline and benefit if theyincrease.  However, the Managing General Partner may from time to timeenter into derivative agreements, usually with a term of two years or less whichmay either fix or collar a price in order to reduce market price fluctuations.The Partnership believes that the pricing provisions of its natural gascontracts are customary in the industry. 

 

-16-

----

TheManaging General Partner currently uses the "Net-Back" method of accounting fortransportation arrangements of natural gas sales.  The Managing GeneralPartner sells gas at the wellhead and collects a price and recognizes revenuesbased on the wellhead sales price since transportation costs downstream of the wellheadare incurred by the Managing General Partner's customers and reflected in thewellhead price.

Salesof oil are recognized when persuasive evidence of a sales arrangement exists,the oil is verified as produced and is delivered from a stock tank to a purchaser,collection of revenue from the sale is reasonably assured, and the sales priceis determinable.  The Partnership does not refine any of its oilproduction.  The Partnership's crude oil production is sold to purchasersat or near the Partnership's wells under short-term purchase contracts atprices and in accordance with arrangements that are customary in the oilindustry.

DerivativeFinancial Instruments

ThePartnership accounts for derivative financial instruments in accordance withFAS Statement No. 133 "Accounting for Derivative Instruments and CertainHedging Activities" as amended.  During 2005, none of the derivativecontracts qualified for hedge accounting under the terms of FAS No. 133. Accordingly, the derivative instruments are recorded as an asset or liabilityon the balance sheet at fair value and the change in the fair value is recordedin oil and gas price risk management loss (gain), net.  Because derivativearrangements are entered into by the Managing General Partner on behalf of thePartnership, the fair value of open derivative positions is reported on thebalance sheet as a net short-term or long-term receivable due from or payabledue to the Managing General Partner.  

The measurement of fair value is based on actively quotedmarket prices, if available. Otherwise, the Managing General Partner seeksindicative price information from external sources including broker quotes andindustry publications. If pricing information from external sources is notavailable, measurement involves judgment and estimates. These estimates arebased on valuation methodologies considered appropriate by the Managing GeneralPartner. 

By using derivative financial instruments to manageexposures to changes in commodity prices, the Partnership exposes itself tocredit risk.  Credit risk is the failure of the counterparty to performunder the terms of the derivative contract.  When the fair value of aderivative contract is positive, the counterparty owes the Managing GeneralPartner, which in turn owes the Partnership thus creating repayment risk. The Managing General Partner minimizes the credit or repayment risk inderivative instruments by entering into transactions with high-qualitycounterparties.

RecentlyIssued Accounting Standards

In June 2005, the FASBissued SFAS No. 154, "Accounting Changes and Error Corrections" - areplacement of APB Opinion No. 20 and FASB Statement No. 3, which replacesAccounting Principles Board Opinion No. 20, "Accounting Changes," andSFAS No. 3, "Reporting Accounting Changes in Interim FinancialStatements," and changes the requirements for the accounting for andreporting of a change in accounting principle. SFAS No. 154 requiresretrospective application for voluntary changes in accounting principle unlessit is impracticable to do so, and it applies to all voluntary changes inaccounting principle.  SFAS No. 154 is effective for accounting changesand corrections of errors made in fiscal years beginning after December 15,2005. Consequently, we will adopt the provisions of SFAS 154 for our fiscalyear beginning January 1, 2006. We currently believe that adoption of theprovisions of SFAS No. 154 will not have a material impact on our financialstatements.

**Item7A.  Quantitative and Qualitative Disclosure About Market Risk**

Market-SensitiveInstruments and Risk Management

ThePartnership's primary market risk exposure is commodity price risk for the oiland gas the Partnership produces and sells.  

Commodity Price Risk

TheManaging General Partner utilizes commodity-based derivative instruments,entered into on behalf of the Partnership, to manage a portion of thePartnership's exposure to price risk from oil and natural gas sales. These instruments consist of CIG (Colorado Interstate Gas) index-basedcontracts traded by JP Morgan for Colorado natural gas production. Thesederivative instruments have the effect of locking in for specified periods (atpredetermined prices or ranges of prices) the prices the Managing GeneralPartner will receive for the volume of oil and natural gas to which thederivative relates.  As a result, while these derivative instruments arestructured to reduce Partnership's exposureto changes in price associated with the derivative commodity, they also limitthe benefit the Partnership might otherwise have received from price changesassociated with the commodity.  The Partnership has adopted the policy ofthe Managing General Partner prohibiting the use of oil and natural gas futureand option contracts for speculative purposes.

**ITEM 9.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ONACCOUNTING AND****FINANCIALDISCLOSURE**

None.

**ITEM 9A. CONTROLS ANDPROCEDURES **

*IntroductoryExplanation* - As disclosed in moredetail in "Item 1 - Business" above, the Partnership has no management or officersbecause all of the management, officers and other employees that may provideservices to or on behalf of the Partnership are employed by the ManagingGeneral Partner.  As used for the disclosures in this Item 9A, managementand officers of the Partnership refers to the management and officers of theManaging General Partner.  

*Evaluationof disclosure controls and procedures*- The Partnership carried out an evaluation, under the supervision and with theparticipation of management including the Chief Executive Officer and the ChiefFinancial Officer, of the effectiveness of the design and operation of itsdisclosure controls and procedures pursuant to Exchange Act Rule 13a-14(a) asof the end of the period covered by this Annual Report on Form 10-K. Based uponand as of the date of this evaluation, the Chief Executive Officer and theChief Financial Officer concluded that as of the date of this report, thePartnership's disclosure controls and procedures were not effective because ofthe material weaknesses described below.

*Materialweaknesses in internal control -*During2005, the Partnership identified material weaknesses relatedto its policies and procedures and technical expertise in U.S. generallyaccepted accounting principles to ensure the preparation of accurate andreliable interim and annual financial statements. Specifically, the Partnershiplacked personnel with sufficient technical accounting and financial reportingexpertise and policies and procedures in place to determine and document theappropriate application of accounting principles. These deficiencies impactedthe Partnership's accounting for derivatives, asset retirement obligations anddepreciation, depletion and amortization, and result in more than a remotelikelihood that a material misstatement of the annual or interim financialstatements would not be prevented or detected.  

Inlight of the material weaknesses described above, the Partnership performedadditional analyses and other post-closing procedures to ensure its financialstatements are prepared in accordance with generally accepted accountingprinciples. Accordingly, notwithstanding the material weaknesses discussed inthis Item 9A, management believes that the financial statements included inthis report fairly present in all material respects our financial position,results of operations and cash flows for the periods presented. 

* *

*Changes in internal control over financial reporting* - 

 

Therehave not been any changes in the Partnership's internal control over financialreporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) of theSecurities Exchange Act of 1934) during the most recent fiscal quarter thathave materially affected or are reasonably likely to materially affect internalcontrol over financial reporting, except for changes in the fourth quarter of2005 as noted below.  

•       The Partnershiphas increased its technical expertise through development of training programsand acquisition of accounting research software during the fourth quarter of2005.  Training will be on-going; however, programs provided during 2005included oil and gas accounting, general accounting and SEC financialreporting.

•       The Partnershiphas enhanced the documentation of its policies and procedures and relatedtemplates and analyses that support the application of accounting principles inseveral areas, including derivatives, oil and gas properties, and assetretirement obligations.

In addition, during the third quarter of fiscal 2005and subsequently in 2006, the Partnership made the following changes andremediation:

 

At the direction of the board of directors and auditcommittee, the Partnership has spent and continues to spend a significantamount of time and resources to improve its control environment.  ThePartnership is committed to instilling strong internal control policies andprocedures and ensuring that the "tone at the top" fully supportsaccuracy and completeness in all financial reporting.  In support of thisposition, the Partnership's progress toward improving internal control overfinancial reporting has been openly communicated with the Audit Committee, andthe Partnership has undertaken to improve the design and effectiveness of itsinternal control over financial reporting. The initiatives developed were bothorganizational and process focused.  Organizational changes made during2005 and through the date of this filing include, among others:

 

•      The Partnership has enhanced the corporate accounting and reporting functionsin the third quarter of 2005 by creating and filling several new positions withprofessionals highly experienced in oil and gas accounting. Two newprofessionals hold degrees in accounting and are Certified Public Accountants.One additional Certified Public Accountant and a financial reporting directorwere hired during 2006.

 

•      The Partnership engaged a team of highly experienced advisors in early 2006 toassist with various accounting research, projects and monitoringactivities.  They assist with accounting and reporting issues including,but not limited to, derivatives, oil and gas activities, new accountingstandards or rules, SEC reporting and on-going monitoring of changes that may impactthe Partnership's application of accounting principles.

 

•      The Partnership began the process of implementing measures related todocumentation of its controls and procedures, segregation of duties, timelyreconciliations and the use of disclosure checklists to support the financialreporting process.

 

The Partnership has also implemented or is planning toimplement several process changes to improve the documentation supportingcertain accounting and reporting activities as well as to improve the documentationof its application of accounting principles.

 

•      The Partnership has evaluated and selected a third-party integrated oil and gasaccounting software system, which it plans to implement during 2006.

 

The Partnership believes the measures taken to dateand planned for the future will address the reported material weaknesses andintends to complete the remediation efforts during 2006.  In addition, thePartnership will continue to develop and implement other initiatives during2006 that will further improve both the effectiveness and efficiency of itsinternal control over financial reporting. 

 

Beginning with the fiscal year ending December 31,2007, Section 404 of the Sarbanes-Oxley Act of 2002 will require us to includean internal control report of management with our Annual Report on Form 10-K.The internal control report must contain (1) a statement of management'sresponsibility for establishing and maintaining adequate internal control overfinancial reporting, (2) a statement identifying the framework used bymanagement to conduct the required evaluation of the effectiveness of ourinternal control over financial reporting, (3) management's assessment of theeffectiveness of our internal control over financial reporting as of the end ofour most recent fiscal year, including a statement as to whether or not ourinternal control over financial reporting is effective, and (4) a statementthat our independent registered public accountants have issued an attestationreport on management's assessment of our internal control over financialreporting.

In order to achieve compliance with Section 404 withinthe prescribed period, management has begun to assess the adequacy of ourinternal control over financial reporting, remediate any control weaknessesthat may be identified, and implement a continuous reporting and improvementprocess for internal control over financial reporting. We expect to continue tomake changes in our internal control over financial reporting during theperiods prior to December 31, 2007, in connection with our Section 404compliance efforts. Except as described above, there have been no changes inour internal control over financial reporting (as defined in Rule 13(a)-15(f)under the Exchange Act) that occurred during the quarters ended June 30, 2005,September 30, 2005 and December 31, 2005, that have materially affected or arereasonably likely to materially affect our internal control over financialreporting.

 (2)  Summary of Significant AccountingPolicies

Partnership Financial StatementPresentation Basis

The financial statements include only thoseassets, liabilities and results of operations of the partners which relate tothe business of the Partnership.  The statements do not include anyassets, liabilities, revenues or expenses attributable to any of the partners'other activities. 

Oil and Gas Properties

The Partnershipaccounts for its oil and gas properties under the successful efforts method ofaccounting. Costs of proved developed producing properties and development dryhole costs are depreciated or depleted by the unit-of-production method basedon estimated proved developed producing oil and gas reserves.  Propertyacquisition costs are depreciated or depleted on the unit-of-production methodbased on estimated proved oil and gas reserves.  The Partnership obtainsnew reserve reports from independent petroleum engineers annually as ofDecember 31st of each year.  The Partnership adjusts for any majoracquisitions, new drilling and divestures during the year as needed.  ThePartnership does not maintain an inventory of undrilledleases.

Upon sale orretirement of significant or entire portions of fields of depreciable or depletable property, the book value thereof less proceeds,is credited or charged to income.  Upon sale of a partial unit ofproperty, the proceeds are credited to accumulated depreciation and depletion.

Impairment ofLong-Lived Assets

Impairment testingfor long-lived assets is required when circumstances indicate those assets maybe impaired.  The Partnership assesses impairment of capitalized costs ofproved oil and gas properties by comparing net capitalized costs to estimatedundiscounted future net cash flows on a field-by-field basis using estimatedproduction based upon prices at which management reasonably estimates suchproducts will be sold. These estimates of future product prices may differ fromcurrent market prices of oil and gas. Any downward revisions to thePartnership's estimates of future production or product prices could result inan impairment of the Partnership's oil and gas properties in subsequentperiods. If net capitalized costs exceed undiscounted future net cash flows, animpairment is recorded.  The measurement of impairment is based onestimated fair value which may consider future discounted cash flows.

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.  Naturalgas is sold by the Managing General Partner under contracts with terms rangingfrom one month up to the life of the well (see Note 3).  Virtually all ofthe Managing General Partner's contracts pricing provisions are tied to amarket index with certain adjustments based on, among other factors, whether awell delivers to a gathering or transmission line, quality of natural gas andprevailing supply and demand conditions, so that the price of the natural gasfluctuates to remain competitive with other available natural gassupplies.  As a result, the Partnership's revenues from the sale ofnatural gas will suffer if market prices decline and benefit if they increase. However, the Managing General Partner may from time to time enter intoderivative agreements, usually with a term of two years or less which mayeither fix or collar a price in order to reduce market price fluctuations. ThePartnership believes that the pricing provisions of its natural gas contractsare customary in 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 wellheadand collects 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.  ThePartnership is currently able to sell all the oil that it can produce underexisting sales contracts with petroleum refiners and marketers.  ThePartnership does not refine any of its oil production.  The Partnership'scrude oil production is sold to purchasers at or near the Partnership's wellsunder short-term purchase contracts at prices and in accordance witharrangements that are customary in the oil industry.

The Partnership sold oil and natural gasto three customers, during 2005, which accounted for 49%, 33% and 18% of thePartnership's total oil and natural gas sales for the period.

AssetRetirement Obligations

The Partnership accounts for assetretirement obligations by recording the fair value of its plugging and abandonmentobligations when incurred, which is at the time the well is completely drilled.Upon initial recognition of an asset retirement obligation, the Partnershipincreases the carrying amount of the long-lived asset by the same amount as theliability. Over time, asset retirement obligations are accreted for the changein their present value. The initial capitalized costs are depleted over the useful lives of the related assets,through charges to depreciation, depletion and amortization. 

####  

Derivative Financial Instruments

The Partnership accounts for derivativefinancial instruments in accordance with FAS Statement No. 133 "Accountingfor Derivative Instruments and Certain Hedging Activities" asamended.  During 2005, none of the derivative contracts qualified forhedge accounting under the terms of FAS No. 133.  Accordingly, thederivative instruments are recorded as an asset or liability on the balancesheet at fair value and the change in the fair value is recorded in oil and gasprice risk management loss (gain), net.  Because derivative arrangementsare entered into by the Managing General Partner on behalf of the Partnership,the fair value of open derivative positions is reported on the balance sheet asa net short-term or long-term receivable due from or payable due to theManaging General Partner.  Amounts due to the Managing General Partner forrealized losses and gains on closed derivative positions are included inaccounts payable in the amount of $81,537 at December 31, 2005. 

The measurement of fair value is basedon actively quoted market prices, if available. Otherwise, the Managing GeneralPartner seeks indicative price information from external sources includingbroker quotes and industry publications. If pricing information from externalsources is not available, measurement involves judgment and estimates. Theseestimates are based on valuation methodologies considered appropriate by theManaging General Partner.

Notes to Financial Statements

 

 

By using derivative financialinstruments to manage exposures to changes in commodity prices, the Partnershipexposes itself to credit risk.  Credit risk is the failure of thecounterparty to perform under the terms of the derivative contract.  Whenthe fair value of a derivative contract is positive, the counterparty owes theManaging General Partner, which in turn owes the Partnership.  TheManaging General Partner minimizes this credit risk by entering intotransactions with high-quality counterparties.

#### Income Taxes

Since thetaxable income or loss of the Partnership is reported in the separate taxreturns of the partners, no provision has been made for income taxes on thePartnership's books.

Use of Estimates

The Partnership has made a number of estimatesand assumptions relating to the reporting of assets and liabilities andrevenues and expenses and the disclosure of contingent assets and liabilitiesto prepare these financial statements in conformity with accounting principlesgenerally accepted in the United States of America. Actual results could differfrom those estimates. Estimates which are particularly significant to thefinancial statements include estimates of oil and gas reserves and future cashflows from oil and gas properties which are used in assessing impairment oflong-lived assets.

FairValue of Financial Instruments

The carrying valuesof the Company's receivables, payables and debt obligations are estimated to besubstantially the same as the fair values as of December 31, 2005.

RecentlyIssued Accounting Standards

In June 2005, the FASB issued SFAS No. 154, "Accounting Changes andError Corrections" - a replacement of APB Opinion No. 20 and FASBStatement No. 3, which replaces Accounting Principles Board Opinion No. 20,"Accounting Changes," and SFAS No. 3, "Reporting AccountingChanges in Interim Financial Statements," and changes the requirements forthe accounting for and reporting of a change in accounting principle. SFAS No.154 requires retrospective application for voluntary changes in accountingprinciple unless it is impracticable to do so, and it applies to all voluntarychanges in accounting principle. SFAS No. 154 is effective for accountingchanges and corrections of errors made in fiscal years beginning after December15, 2005. Consequently, we will adopt the provisions of SFAS 154 for our fiscalyear beginning January 1, 2006. We currently believe that adoption of theprovisions of SFAS No. 154 will not have a material impact on our financialstatements.

Notes to Financial Statements

 

 

As described above, the Managing General Partnerutilizes commodity-based derivative instruments, entered into on behalf of thePartnership, to manage a portion of the Partnership's exposure to price riskfrom oil and natural gas sales.  These instruments consist of CIG(Colorado Interstate Gas) index-based contracts traded by JP Morgan forColorado natural gas production. These derivative instruments have the effect oflocking in for specified periods (at predetermined prices or ranges of prices)the prices the Managing General Partner will receive for the volume of oil andnatural gas to which the derivative relates.  

The fair value of the commodity basedderivatives was $(22,588) at December 31, 2005.  The Partnershiprecognized in the statement of operations a realized loss on commodity basedderivatives of $159,037 for the year ended December 31, 2005.

Performance StandardObligation of Managing General Partner

The Agreement provides for theenhancement of investor cash distributions if the Partnership does not meet aperformance standard defined in the Agreement during the first 10 yearsbeginning 6 months after the close of the Partnership.  In general, if theaverage annual rate of return to the Investor Partners is less than 12.5% oftheir subscriptions, the allocation rate of cash distributions to InvestorPartners will increase by one-half of the Managing General Partner's interestuntil the average annual rate increases to 12.5%, with a corresponding decreaseto the Managing General Partner.  The 12.5% rate of return is calculatedby including the estimated benefit of a 25% income tax savings on theinvestment in the first year in addition to cash distributions made to theInvestor Partners.  During 2005, no obligation of the Managing GeneralPartner arose under this provision.

(8)  Standardized Measure of Discounted Future Net Cash Flows and Changes ThereinRelating to Proved Oil

and Gas Reserves (Unaudited)

Summarized in the followingtable is information for the Partnership with respect to the standardizedmeasure of discounted future net cash flows relating to proved oil and gas reserves. Future cash inflows are computed by applying year-end prices of oil and gasrelating to the Partnership's proved reserves to the year-end quantities ofthose reserves.  Future production, development, site restoration andabandonment costs are derived based on current costs assuming continuation ofexisting economic conditions.

It is necessary to emphasize that thedata presented should not be viewed as representing the expected cash flowfrom, or current value of, existing proved reserves since the computations arebased on a large number of estimates and arbitrary assumptions.  Reservequantities cannot be measured with precision and their estimation requires manyjudgmental determinations and frequent revisions.  The required projectionof production and related expenditures over time requires further estimateswith respect to pipeline availability, rates of demand and governmental control.Actual future prices and costs are likely to be substantially different fromthe current prices and costs utilized in the computation of reportedamounts.  Any analysis or evaluation of the reported amounts should givespecific recognition to the computational methods utilized and the limitationsinherent therein.
