BUSINESS General The Geodyne Institutional/Pension Energy Income P-1 Limited Partnership (the "P-1 Partnership") is a limited partnership formed under the Texas Revised Limited Partnership Act and the Geodyne Institutional/Pension Energy Income Limited Partnership P-3 (the "P-3 Partnership"), Geodyne Institutional/Pension Energy Income Limited Partnership P-4 (the "P-4 Partnership"), Geodyne Institutional/Pension Energy Income Limited Partnership P-5 (the "P-5 Partnership"), and Geodyne Institutional/Pension Energy Income Limited Partnership P-6 (the "P-6 Partnership") are limited partnerships formed under the Oklahoma Revised Uniform Limited Partnership Act (collectively, the "Partnerships"). Each Partnership is composed of Geodyne Resources, Inc. ("Geodyne"), a Delaware corporation, as the general partner, Geodyne Institutional Depository Company, a Delaware corporation, as the sole initial limited partner, and public investors as substitute limited partners (the "Limited Partners"). The Partnerships commenced operations on the dates set forth below: Date of Partnership Activation ----------- ----------------- P-1 October 25, 1988 P-3 May 10, 1989 P-4 November 21, 1989 P-5 February 27, 1990 P-6 September 5, 1990 Immediately following activation, each Partnership invested as a general partner in a separate Oklahoma general partnership which actually conducts the Partnerships' operations. Geodyne serves as managing partner of such general partnerships. Unless the context indicates otherwise, all references to any single Partnership or all of the Partnerships in this Annual Report on Form 10-K ("Annual Report") are references to the Partnership and its related general partnership, collectively. In addition, unless the context indicates otherwise, all references to the "General Partner" in this Annual Report are references to Geodyne as the general partner of the Partnerships, and as the managing partner of the related general partnerships. The General Partner currently serves as general partner of 26 limited partnerships, including the Partnerships. The General Partner is a wholly-owned subsidiary of Samson Investment Company. Samson Investment Company and its various corporate subsidiaries, including the General Partner (collectively "Samson"), are primarily engaged in the production and development of and exploration for oil and gas reserves and the acquisition and operation of producing properties. At December 31, 2005, Samson owned interests in approximately 18,000 oil -4- and gas wells located in 18 states of the United States and the countries of Canada and Venezuela. At December 31, 2005, Samson operated approximately 5,700 oil and gas wells located in 14 states of the United States, as well as Canada and Venezuela. The Partnerships are currently engaged in the business of owning net profits and royalty interests in oil and gas properties located in the continental United States. Most of the net profits interests acquired by the Partnerships have been carved out of working interests in producing properties ("Working Interests") which were acquired by affiliated oil and gas investment programs (the "Affiliated Programs"). Net profits interests entitle the Partnerships to a share of net revenues from producing properties measured by a specific percentage of the net profits realized by such Affiliated Programs on those properties. Except where otherwise noted, references to certain operational activities of the Partnerships are actually the activities of the Affiliated Programs. As the holder of a net profits interest, a Partnership is not liable to pay any amount by which oil and gas operating costs and expenses exceed revenues for any period, although any deficit, together with interest, is applied to reduce the amounts payable to the Partnership in subsequent periods. As used throughout this Annual Report, the Partnerships' net profits and royalty interests in oil and gas sales will be referred to as "Net Profits" and the Partnerships' net profits and royalty interests in oil and gas properties will be collectively referred to as "Net Profits Interests." In order to prudently manage the properties which are burdened by the Partnerships' Net Profits Interests, it may be appropriate for drilling operations to be conducted on such properties. Since the Partnerships' Net Profits are calculated after considering such costs, the Partnerships also indirectly engage in development drilling. As limited partnerships, the Partnerships have no officers, directors, or employees. They rely instead on the personnel of the General Partner and Samson. As of February 15, 2006, Samson employed approximately 1,300 persons. No employees are covered by collective bargaining agreements, and management believes that Samson provides a sound employee relations environment. For information regarding the executive officers of the General Partner, see "Item 10. Directors and Executive Officers of the General Partner." The General Partner's and the Partnerships' principal place of business is located at Samson Plaza, Two West Second Street, Tulsa, Oklahoma 74103, and their telephone number is (918) 583-1791 or (888) 436-3963 [(888) GEODYNE]. Pursuant to the terms of the partnership agreements for the Partnerships (the "Partnership Agreements"), the Partnerships would have terminated on December 31, 2005. However, the Partnership Agreements provide that the General Partner may extend the term of each Partnership for up to five periods of two years each. The General Partner has extended the terms of the Partnerships for the first two-year period to December 31, 2007. As of the date of this Annual -5- Report, the General Partner has not determined whether to further extend the term of any of the Partnerships. Funding Although the partnership agreement for each Partnership (the "Partnership Agreement") permits each Partnership to incur borrowings, operations and expenses are currently funded out of revenues from each Partnership's Net Profits Interests. The General Partner may, but is not required to, advance funds to a Partnership for the same purposes for which Partnership borrowings are authorized. Principal Products Produced and Services Rendered The Partnerships' sole business is the holding of certain Net Profits Interests. The Partnerships do not refine or otherwise process crude oil and condensate. The Partnerships do not hold any patents, trademarks, licenses, or concessions and are not a party to any government contracts. The Partnerships have no backlog of orders and do not participate in research and development activities. The Partnerships are not presently encountering shortages of oilfield tubular goods, compressors, production material, or other equipment. However, substantial increases in the global price of steel as well as increases in the prices for oil and gas supplies and services will further increase the costs of any future workover, recompletion or drilling activities indirectly conducted by the Partnerships. Competition and Marketing The primary source of liquidity and Partnership cash distributions comes from the net revenues generated from the sale of oil and gas produced from the Partnerships' oil and gas properties. The level of net revenues is highly dependent upon the total volumes of oil and natural gas sold. Oil and gas reserves are depleting assets and will experience production declines over time, thereby likely resulting in reduced net revenues. The level of net revenues is also highly dependent upon the prices received for oil and gas sales, which prices have historically been very volatile and may continue to be so. Additionally, lower oil and natural gas prices may reduce the amount of oil and gas that is economic to produce and reduce the Partnerships' revenues and cash flow. Various factors beyond the Partnerships' control will affect prices for oil and natural gas, such as: * Worldwide and domestic supplies of oil and natural gas; * The ability of the members of the Organization of Petroleum Exporting Countries ("OPEC") to agree upon and maintain oil prices and production quotas; * Political instability or armed conflict in oil-producing regions or around major shipping areas; -6- * The level of consumer demand and overall economic activity; * The competitiveness of alternative fuels; * Weather conditions and the impact of weather-related events; * The availability of pipelines for transportation; * Domestic and foreign government regulations and taxes; and * Market expectations. It is not possible to predict the future direction of oil or natural gas prices or whether the above discussed trends will remain. Operating costs, including General and Administrative Expenses, may not decline over time, may increase, or may experience only a gradual decline, thus adversely affecting net revenues as either production or oil and natural gas prices decline. In any particular period, net revenues may also be affected by either the receipt of proceeds from property sales or the incursion of additional costs as a result of well workovers, recompletions, new well drilling, and other events. Significant Customers The following customers accounted for ten percent or more of the oil and gas sales attributable to the Partnerships' Net Profits Interests during the year ended December 31, 2005: Partnership Customer Percentage ----------- ----------------------------- ---------- P-1 Duke Energy Field Services, Inc. ("Duke") 10.7% P-3 Duke 13.9% P-4 ConocoPhillips Company 27.8% Gulfterra Central Point Alloc. 21.8% Enogex Services Corporation ("Enogex") 10.1% P-5 ONEOK Texas Energy Resources ("ONEOK") 21.0% Enogex 18.2% Cinergy Marketing 11.7% Duke 10.3% P-6 Duke 19.8% Kinder Morgan, Inc. 17.1% ONEOK 13.3% In the event of interruption of purchases by one or more of these significant customers or the cessation or material change in availability of open access transportation by pipeline transporters, the Partnerships may encounter difficulty in marketing gas and in maintaining historic sales levels. Management does not expect any of its open access transporters to seek authorization to terminate their transportation services. Even if the services were terminated, -7- management believes that alternatives would be available whereby the Partnerships would be able to continue to market their gas. The Partnerships' principal customers for crude oil production are refiners and other companies which have pipeline facilities near the producing properties in which the Partnerships own Net Profits Interests. In the event pipeline facilities are not conveniently available to production areas, crude oil is usually trucked by purchasers to storage facilities. Oil, Gas, and Environmental Control Regulations Regulation of Production Operations -- The production of oil and gas is subject to extensive federal and state laws and regulations governing a wide variety of matters, including the drilling and spacing of wells, allowable rates of production, prevention of waste and pollution, and protection of the environment. In addition to the direct costs borne in complying with such regulations, operations and revenues may be impacted to the extent that certain regulations limit oil and gas production to below economic levels. Regulation of Sales and Transportation of Oil and Gas -- Sales of crude oil and condensate are made at market prices and are not subject to price controls. The sale of gas may be subject to both federal and state laws and regulations. The provisions of these laws and regulations are complex and affect all who produce, resell, transport, or purchase gas. Although virtually all of the natural gas production affecting the Partnerships is not subject to price regulation, other regulations affect the availability of gas transportation services and the ability of gas consumers to continue to purchase or use gas at current levels. Accordingly, such regulations may have a material effect on the Partnerships' Net Profits and projections of future Net Profits. Future Legislation -- Legislation affecting the oil and gas industry is under constant review for amendment or expansion. Because such laws and regulations are frequently amended or reinterpreted, management is unable to predict what additional energy legislation may be proposed or enacted or the future cost and impact of complying with existing or future regulations. Regulation of the Environment -- Oil and gas operations are subject to numerous laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection. Compliance with such laws and regulations, together with any penalties resulting from noncompliance, may decrease the Partnerships' Net Profits. Management anticipates that various local, state, and federal environmental control agencies will have an increasing impact on oil and gas operations. -8- Insurance Coverage Exploration for and production of oil and gas are subject to many inherent risks, including blowouts, pollution, fires, and other casualties. The Partnerships maintain insurance coverage as is customary for entities of a similar size engaged in similar operations, but losses can occur from uninsurable risks or in amounts in excess of existing insurance coverage. For example, many types of pollution and contamination can exist, undiscovered, for long periods of time and can result in substantial environmental liabilities which are not insured. The occurrence of an event which is not fully covered by insurance could have a material adverse effect on the Partnerships' financial condition and results of operations in that it could negatively impact the cash flow received from the Net Profits Interests. ITEM 1A. RISK FACTORS The following factors, among others, could have a material adverse effect upon the Partnerships' business, financial condition, and results of operations. The following discussion of risk factors should be read in conjunction with the combined financial statements and related notes included herein. Because of these and other factors, past financial performance should not be considered an indication of future performance. Oil And Natural Gas Prices Fluctuate Due To A Number Of -------------------------------------------------------- Uncontrollable Factors, And Any Decline Will Adversely Affect The ----------------------------------------------------------------- Partnerships' Financial Condition. ---------------------------------- The Partnerships' results of operations depend upon the prices they receive for their oil and natural gas. We sell most of the Partnerships' oil and natural gas liquids at current market prices rather than through fixed-price contracts. Historically, the markets for oil and natural gas have been volatile and are likely to remain so. The prices we receive depend upon factors beyond our control, including: * political instability or armed conflict in oil-producing regions; * weather conditions; * the supply of domestic and foreign oil and natural gas; * the ability of members of OPEC to agree upon and maintain prices and production levels; * the level of consumer demand and overall economic activity; * worldwide economic demand; * the price and availability of alternative fuels; * domestic and foreign governmental regulations and taxes; -9- * the proximity to and capacity of transportation facilities; and * the effect of worldwide energy conservation measures. Government regulations, such as regulation of natural gas transportation and price controls, can affect product prices in the long term. These external factors and the volatile nature of the energy markets make it difficult to reliably estimate future prices of oil and natural gas. Any decline in oil and natural gas prices adversely affects the Partnerships' financial condition. If the oil and gas industry experiences significant price declines, the Partnerships may not be able to maintain their current level of cash distributions. See "Item 1 - Business - Competition and Marketing" and "Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations." Reserve Estimates Depend On Many Assumptions That May Turn Out To ----------------------------------------------------------------- Be Inaccurate. Any Material Inaccuracies In The Partnerships' -------------------------------------------------------------- Reserve Estimates Or Underlying Assumptions Could Cause ------------------------------------------------------- The Quantities And Net Present Value Of Their Reserves To Be ------------------------------------------------------------ Overstated. ----------- Estimating quantities of proved oil and natural gas reserves is a complex process. It requires interpretations of available technical data and various assumptions, including assumptions relating to economic factors. Any significant inaccuracies in these interpretations or assumptions or changes of condition could cause the quantities and net present value of the Partnerships' reserves to be overstated. To prepare estimates of economically recoverable oil and natural gas reserves and future net cash flows, we analyze many variable factors, such as historical production from the area compared with production rates from other producing areas. We also analyze available geological, geophysical, production and engineering data, and the extent, quality and reliability of this data can vary. The process also involves economic assumptions relating to commodity prices, production costs, severance and excise taxes, capital expenditures and workover and remedial costs. Actual results most likely will vary from our estimates. Any significant variance could reduce the estimated quantities and present value of reserves shown in this Annual Report. You should not assume that the present value of future net cash flows from the Partnerships' proved reserves shown in this Annual Report is the current market value of their estimated oil and natural gas reserves. In accordance with Securities and Exchange Commission -10- requirements, the Partnerships base the estimated discounted future net cash flows from their proved reserves on prices and costs on the date of the estimate. Actual current and future prices and costs may differ materially from those used in the earlier net present value estimate, and as a result, net present value estimates using current prices and costs may be significantly less than the earlier estimate which is provided in this Annual Report. See "Item 2 - Properties-Proved Reserves and Net Present Value". Drilling Oil And Natural Gas Wells Is A High-Risk Activity And -------------------------------------------------------------- Subjects Us To A Variety Of Factors That We Cannot Control. ----------------------------------------------------------- Drilling oil and natural gas wells, including development wells, involves numerous risks, including the risk that the Affiliated Programs may not encounter commercially productive oil and natural gas reservoirs. While the Affiliated Programs do not expend a significant portion of their capital on drilling activities, to the extent they do drill wells this can be a significant indirect risk factor to the Partnerships. The Affiliated Programs may not recover all or any portion of their investment in new wells. The presence of unanticipated pressures or irregularities in formations, miscalculations or accidents may cause the Partnerships' drilling activities to be unsuccessful and result in a total loss of investment. Further, drilling operations may be curtailed, delayed or canceled as a result of a variety of factors, including: * unexpected drilling conditions; * title problems; * restricted access to land for drilling or laying pipeline; * pressure or irregularities in formations; * equipment failure or accidents; * adverse weather conditions; and * costs of, or shortages or delays in the availability of, drilling rigs, tubular materials and equipment. The Marketability Of The Partnerships' Production Is Dependent -------------------------------------------------------------- Upon Transportation And Processing Facilities Over Which We Have ---------------------------------------------------------------- No Control. ----------- The marketability of the Partnerships' production depends in part upon the availability, proximity and capacity of pipelines, natural gas gathering systems and processing facilities. Any significant change in market factors affecting these infrastructure facilities could harm their business. The Partnerships deliver oil and natural gas through gathering systems and pipelines that they do not own. These facilities may be temporarily unavailable due to market conditions or mechanical reasons, or may not be available to us in the future. -11- Reliance On Third Party Operators --------------------------------- A substantial portion of the Partnerships' properties are operated by third parties. The Partnerships have little, if any, control over the operational decisions and costs associated with these properties. In addition, the Partnerships are totally reliant on the third party operators' internal controls associated with the operators' accounting for revenues and expenses. No Market For Units ------------------- The Partnerships' Units are not listed on any exchange or national market system, and there is no established public trading market for the Units. You may only sell your Units via (i) the General Partner's annual Repurchase Offer; (ii) transfers facilitated by secondary trading firms and matching services; and (iii) occasional "4.9% tender offers" which are made for the Units. Secondary market activity for the Units has been limited and varies among the Partnerships. See "Item 5 - Market for Units and Related Limited Partner Matters". Limited Life ------------ The Partnerships are currently scheduled to terminate on December 31, 2007. Even if the General Partner exercises its right to extend the Partnerships' terms for four additional two-year periods, the Partnerships will terminate no later than December 31, 2015. Upon termination the Partnerships' assets will be sold. There is no assurance that the market for the sale of the Partnerships' assets will be favorable at such time. The Partnerships Are Subject To Complex Federal, State And Local ---------------------------------------------------------------- Laws And Regulations That Could Adversely Affect Their Business. ---------------------------------------------------------------- Extensive federal, state and local regulation of the oil and gas industry significantly affects the Partnerships' operations. In particular, they are subject to stringent environmental regulations. These regulations increase the costs of planning, designing, drilling, installing, operating and abandoning oil and natural gas wells and other related facilities. These regulations may become more demanding in the future. Matters subject to regulation include: * discharge permits for drilling operations; * drilling bonds; * spacing of wells; * unitization and pooling of properties; * environmental protection; * reports concerning operations; and * taxation. -12- Under these laws and regulations, the Partnerships could be liable for: * personal injuries; * property damage; * oil spills; * discharge of hazardous materials; * reclamation costs; * remediation and clean-up costs; and * other environmental damages. While the Partnerships maintain insurance coverage customary for companies similar to their size and operations, losses can occur from uninsurable risks or in amounts in excess of existing insurance coverage. See "Item 1 - Business." Conflicts Of Interest --------------------- Direct and indirect conflicts of interests exist among the Partnerships and among a Partnership and the General Partner and its affiliates. The General Partner and its affiliates engage in many aspects of the oil and gas business, including acting as a general partner of a number of affiliated oil and gas limited partnerships. The General Partner and its affiliates may engage in transactions with a Partnership, and Partnerships will frequently engage in transactions with other oil and gas limited partnerships. These conflicts could relate to the sale of oil and gas properties, the determination of the Partnerships' Repurchase Prices, and the determination of whether to continue the Partnerships past their scheduled termination date of December 31, 2007. See "Item 13 - Certain Relationships and Related Transactions". Payments To The General Partner ------------------------------- The General Partner receives reimbursements for General and Administrative Expenses. The General Partner also receives a share of Partnership cash distributions. See "Item 11 - Executive Compensation" and "Item 8 - Financial Statements and Supplementary Data." Financial Capability Of General Partner --------------------------------------- The General Partner has limited financial resources. Contingencies may arise which will require funding beyond its financial resources. Even if such financial resources are available, the General Partner is not required to lend money or to fund any financial obligations of the Partnerships. -13- Liability And Indemnification Of General Partner And Related ------------------------------------------------------------ Parties ------- Although the General Partner generally will be liable for the obligations of the Partnerships, the Partnership Agreements provide that the claims of third parties will be initially satisfied from Partnership assets. The Partnership Agreements also provide, subject to certain conditions, that the Partnerships will reimburse (i.e. "indemnify") the General Partner and its affiliates for certain costs, claims and expenses. ITEM 1B. UNRESOLVED STAFF COMMENTS None. ITEM 2. PROPERTIES Well Statistics The following table sets forth the number of productive wells as of December 31, 2005 in which the Partnerships had a Net Profits Interest which was carved from a working interest. P/ship Number of Wells(1) ------ --------------------------- Total Oil Gas ----- --- --- P-1 826 608 218 P-3 871 610 261 P-4 215 54 161 P-5 96 18 78 P-6 152 37 115 - --------------- (1) The designation of a well as an oil well or gas well is made by the General Partner based on the relative amount of oil and gas reserves for the well. Regardless of a well's oil or gas designation, it may produce oil, gas, or both oil and gas. Drilling Activities During the year ended December 31, 2005, the Partnerships indirectly participated (through their Net Profits Interests) in the developmental drilling activities described below. -14- P-1 PARTNERSHIP - --------------- REVENUE WELL NAME COUNTY ST.

The schedule of quantities of proved oil and gas reserves was prepared by the General Partner in accordance with the rules prescribed by the Securities and Exchange Commission (the "SEC"). Certain reserve information was reviewed by Ryder Scott Company, L.P. ("Ryder Scott"), an independent petroleum engineering firm. As used throughout this Annual Report, "proved reserves" refers to those estimated quantities of crude oil, gas, and gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known oil and gas reservoirs under existing economic and operating conditions. Net present value represents estimated future gross cash flow from the production and sale of proved reserves, net of estimated oil and gas production costs (including production taxes, ad valorem taxes, and operating expenses) and estimated future development costs, discounted at 10% per annum. Net present value attributable to the Partnerships' proved reserves was calculated on the basis of current costs and prices at December 31, 2005. Such prices were not escalated except in certain circumstances where escalations were fixed and readily determinable in accordance with applicable contract provisions. Oil and gas prices at December 31, 2005 ($61.06 per barrel and $10.08 per Mcf, respectively) were substantially higher than the prices in effect on December 31, 2004 ($43.36 per barrel and $6.02 per Mcf, respectively). This increase in oil and gas prices has caused the estimates of remaining economically recoverable reserves, as well as the values placed on said reserves, at December 31, 2005 to be higher than such estimates and values at December 31, 2004. The prices used in calculating the net present value attributable to the Partnerships' proved reserves do not necessarily reflect market prices for oil and gas production subsequent to December 31, 2005. In fact, as of the date of this Annual Report, natural gas prices have declined significantly from the December 31, 2005 price. There can be no assurance that the prices used in calculating the net present value of the Partnerships' proved reserves at December 31, 2005 will actually be realized for such production. The process of estimating oil and gas reserves is complex, requiring significant subjective decisions in the evaluation of available geological, engineering, and economic data for each reservoir. The data for a given reservoir may change substantially over time as a result of, among other things, additional development activity, production history, and viability of production under varying economic conditions; consequently, it is reasonably possible that material revisions to existing reserve estimates may occur in the near future. Although every reasonable effort has been made to ensure that these reserve estimates represent the most accurate assessment possible, the significance of the subjective decisions required and variances in available data for various reservoirs make these estimates generally less precise than other estimates presented in connection with financial statement disclosures. -25- Proved Reserves and Net Present Values From Proved Reserves As of December 31, 2005(1) P-1 Partnership: - --------------- Estimated proved reserves: Gas (Mcf) 2,192,218 Oil and liquids (Bbls) 240,494 Net present value (discounted at 10% per annum) $12,711,355 P-3 Partnership: - --------------- Estimated proved reserves: Gas (Mcf) 3,450,217 Oil and liquids (Bbls) 316,480 Net present value (discounted at 10% per annum) $18,996,635 P-4 Partnership: - --------------- Estimated proved reserves: Gas (Mcf) 1,825,768 Oil and liquids (Bbls) 47,507 Net present value (discounted at 10% per annum) $ 9,422,988 P-5 Partnership: - --------------- Estimated proved reserves: Gas (Mcf) 2,201,499 Oil and liquids (Bbls) 40,130 Net present value (discounted at 10% per annum) $ 9,341,278 P-6 Partnership: - --------------- Estimated proved reserves: Gas (Mcf) 3,330,307 Oil and liquids (Bbls) 126,115 Net present value (discounted at 10% per annum) $15,133,718 - --------- (1) Includes certain gas balancing adjustments which cause the gas volumes and net present values to differ from the reserve reports -26- which were prepared by the General Partner and reviewed by Ryder Scott. No estimates of the proved reserves of the Partnerships comparable to those included herein have been included in reports to any federal agency other than the SEC. Additional information relating to the Partnerships' proved reserves is contained in Note 4 to the Partnerships' financial statements, included in Item 8 of this Annual Report. Significant Properties The following table sets forth the number and percent of each Partnership's total wells which are operated by affiliates of the Partnerships as of December 31, 2005: Operated Wells -------------------------------- Partnership Number Percent ----------- ------ ------- P-1 34 1% P-3 58 2% P-4 21 7% P-5 105 28% P-6 147 28% The following table sets forth certain well and reserve information as of December 31, 2005 for each oil and gas basin which holds a significant portion of the value of the Partnerships' properties.

Following is a description of those oil and gas properties whose revisions in the estimated proved reserves (based on equivalent barrels of oil) as of December 31, 2005, as compared to December 31, 2004, were significant to the P-6 Partnership: The P-6 Partnership's estimated proved reserves decreased approximately 63,000 barrels of oil equivalent ("boe") in the Karon Unit, a large unitized property in Live Oak County, Texas, from December 31, 2004 to December 31, 2005, primarily due to a revised forecast in reserves based on actual production experience. -28- The P-6 Partnership's estimated proved reserves decreased approximately 55,000 boe in the O'Byrne, Eva GU #2, located in Upshur County, Texas, from December 31, 2004 to December 31, 2005, primarily due to a revised forecast in reserves based on actual production experience and an increase in monthly lease operating expenses. There were no significant revisions in the P-1, P-3, P-4 and P-5 Partnerships. Title to Oil and Gas Properties Management believes that the Partnerships have satisfactory title to their Net Profits Interests. Record title to all of the properties subject to the Partnerships' Net Profits Interests is held by either the Partnerships or Geodyne Nominee Corporation, an affiliate of the General Partner. Title to the Partnerships' Net Profits Interests is subject to customary royalty, overriding royalty, carried, working, and other similar interests and contractual arrangements customary in the oil and gas industry, to liens for current taxes not yet due, and to other encumbrances. Management believes that such burdens do not materially detract from the value of such properties or from the Partnerships' Net Profits Interests therein or materially interfere with their use in the operation of the Partnerships' business. ITEM 3. LEGAL PROCEEDINGS To the knowledge of the General Partner, neither the General Partner nor the Partnerships or their properties are subject to any litigation, the results of which would have a material effect on the Partnerships' or the General Partner's financial condition or operations. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF LIMITED PARTNERS There were no matters submitted to a vote of the Limited Partners of any Partnership during 2005. -29- PART II. ITEM 5. MARKET FOR UNITS AND RELATED LIMITED PARTNER MATTERS As of March 1, 2006, the number of Units outstanding and the approximate number of Limited Partners of record in the Partnerships were as follows: Number of Limited Partnership Units Partners ----------- --------- -------- P-1 108,074 683 P-3 169,637 1,150 P-4 126,306 775 P-5 118,449 858 P-6 143,041 653 Units were initially sold for a price of $100. The Units are not traded on any exchange and there is no public trading market for them. The General Partner is aware of certain transfers of Units between unrelated parties, some of which are facilitated by secondary trading firms and matching services. In addition, as further described below, the General Partner is aware of certain "4.9% tender offers" which have been made for the Units. The General Partner believes that the transfers between unrelated parties have been limited and sporadic in number and volume. Other than trades facilitated by certain secondary trading firms and matching services, no organized trading market for Units exists and none is expected to develop. Due to the nature of these transactions, the General Partner has no verifiable information regarding prices at which Units have been transferred. Further, a transferee may not become a substitute Limited Partner without the consent of the General Partner. Pursuant to the terms of the Partnership Agreements, the General Partner is obligated to annually issue a repurchase offer based on the estimated future net revenues from the Partnerships' reserves and is calculated pursuant to the terms of the Partnership Agreements. Such repurchase offer is recalculated monthly in order to reflect cash distributions to the Limited Partners and extraordinary events. The following table sets forth the General Partner's repurchase offer per Unit as of the periods indicated. For purposes of this Annual Report, a Unit represents an initial subscription of $100 to a Partnership. -30- Repurchase Offer Prices ----------------------- 2004 2005 2006 ------------------------- ------------------------- ---- 1st 2nd 3rd 4th 1st 2nd 3rd 4th 1st P/ship Qtr.

The General Partner does not know the terms of these offers or the prices received by the Limited Partners who accepted these offers. Cash Distributions Cash distributions are primarily dependent upon a Partnership's cash receipts from its Net Profits Interests and cash requirements of the Partnership. Distributable cash is determined by the General Partner at the end of each calendar quarter and distributed to the Limited Partners within 45 days after the end of the quarter. Distributions are restricted to cash on hand less amounts required to be retained out of such cash as determined in the sole judgment of the General Partner to pay costs, expenses, or other Partnership obligations whether accrued or anticipated to accrue. In certain instances, the General Partner may not distribute the full amount of cash receipts which might otherwise be available for distribution in an effort to equalize or stabilize the amounts of quarterly distributions. Any available amounts not distributed are invested and the interest or income thereon is for the accounts of the Limited Partners. -31- The following is a summary of cash distributions paid to the Limited Partners during 2004 and 2005 and the first quarter of 2006: Cash Distributions ------------------ 2004 ----------------------------------------------- 1st 2nd 3rd 4th P/ship Quarter Quarter Quarter Quarter ------ ------- ------- ------- ------- P-1 $2.63 $2.89 $2.69 $2.97 P-3 2.36 2.75 2.37 2.76 P-4 1.91 2.31 2.27 2.85 P-5 1.66 1.53 1.90 1.85 P-6 2.76 2.62 2.66 3.05 2005 2006 ----------------------------------------------- ------- 1st 2nd 3rd 4th 1st P/ship Quarter Quarter Quarter Quarter Quarter ------ ------- ------- ------- ------- ------- P-1 $2.80 $2.82 $3.25 $3.56 $4.29 P-3 2.43 2.62 3.09 3.27 4.04 P-4 2.68 2.33 2.69 2.73 3.64 P-5 1.82 2.02 2.40 2.59 2.51 P-6 1.70 3.31 2.75 2.86 3.31 ITEM 6.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Use of Forward-Looking Statements and Estimates This Annual Report contains certain forward-looking statements. The words "anticipate," "believe," "expect," "plan," "intend," "estimate," "project," "could," "may," and similar expressions are intended to identify forward-looking statements. Such statements reflect management's current views with respect to future events and financial performance. This Annual Report also includes certain information which is, or is based upon, estimates and assumptions. Such estimates and assumptions are management's efforts to accurately reflect the condition and operation of the Partnerships. Use of forward-looking statements and estimates and assumptions involve risks and uncertainties which include, but are not limited to, the volatility of oil and gas prices, the uncertainty of reserve information, the operating risk associated with oil and gas properties (including the risk of personal injury, death, property damage, damage to the well or producing reservoir, environmental contamination, and other operating risks), the prospect of changing tax and regulatory laws, the availability and capacity of processing and transportation facilities, the accuracy of third party payments and billings, the general economic climate, the supply and price of foreign imports of oil and gas, the level of consumer product demand, and the price and availability of alternative fuels. Should one or more of these risks or uncertainties occur or should estimates or underlying assumptions prove incorrect, actual conditions or results may vary materially and adversely from those stated, anticipated, believed, estimated, or otherwise indicated. General Discussion The following general discussion should be read in conjunction with the analysis of results of operations provided below. The primary source of liquidity and Partnership cash distributions comes from the net revenues generated from the sale of oil and gas produced from the Partnerships' oil and gas properties. The level of net revenues is highly dependent upon the prices received for oil and gas sales, which prices have historically been very volatile and may continue to be so. Additionally, lower oil and natural gas prices may reduce the amount of oil and gas that is economic to produce and reduce the Partnerships' revenues and cash flow. Various factors beyond the Partnerships' control will affect prices for oil and natural gas, such as: -38- * Worldwide and domestic supplies of oil and natural gas; * The ability of the members of OPEC to agree upon and maintain oil prices and production quotas; * Political instability or armed conflict in oil-producing regions or around major shipping areas; * The level of consumer demand and overall economic activity; * The competitiveness of alternative fuels; * Weather conditions and the impact of weather-related events; * The availability of pipelines for transportation; * Domestic and foreign government regulations and taxes; and * Market expectations. It is not possible to predict the future direction of oil or natural gas prices or whether the above discussed trends will remain. Operating costs, including General and Administrative Expenses, may not decline over time, may increase, or may experience only a gradual decline, thus adversely affecting net revenues as either production or oil and natural gas prices decline. In any particular period, net revenues may also be affected by either the receipt of proceeds from property sales or the incursion of additional costs as a result of well workovers, recompletions, new well drilling, and other events. In addition to pricing, the level of net revenues is also highly dependent upon the total volumes of oil and natural gas sold. Oil and gas reserves are depleting assets and will experience production declines over time, thereby likely resulting in reduced net revenues. Despite this general trend of declining production, several factors can cause the volumes of oil and gas sold to increase, remain relatively constant, or decrease at an even greater rate over a given period. These factors include, but are not limited to: * Geophysical conditions which cause an acceleration of the decline in production; * The shutting in of wells (or the opening of previously shut-in wells) due to low oil and gas prices (or high oil and gas prices), mechanical difficulties, loss of a market or transportation, or performance of workovers, recompletions, or other operations in the well; * Prior period volume adjustments (either positive or negative) made by operators of the properties; * Adjustments in ownership or rights to production in accordance with agreements governing the operation or ownership of the well (such as adjustments that occur at payout or due to gas balancing); and * Completion of enhanced recovery projects which increase production for the well. Many of these factors are very significant as related to a single well or as related to many wells over a short period of time. -39- However, due to the large number of wells owned by the Partnerships, these factors are generally not material as compared to the normal decline in production experienced on all remaining wells. Results of Operations An analysis of the change in net oil and gas operations (oil and gas sales, less lease operating expenses and production taxes), is presented in the tables following "Results of Operations" under the heading "Average Proceeds and Units of Production." Following is a discussion of each Partnerships' results of operations for the year ended December 31, 2005 as compared to the year ended December 31, 2004 and for the year ended December 31, 2004 as compared to the year ended December 31, 2003. P-1 Partnership --------------- Year Ended December 31, 2005 Compared to Year Ended December 31, 2004 -------------------------------------- Total Net Profits increased $628,000 (42.4%) in 2005 as compared to 2004. Of this increase $283,000 and $471,000, respectively, were related to increases in the average prices of oil and gas sold. These increases were partially offset by decreases of (i) $27,000 and $62,000, respectively, related to decreases in volumes of oil and gas sold and (ii) $37,000 related to an increase in production expenses. Volumes of oil and gas sold decreased 741 barrels and 13,384 Mcf, respectively, in 2005 as compared to 2004. The decrease in volumes of oil sold was primarily due to (i) negative prior period volume adjustments made by the operators on several wells during 2005, (ii) similar positive prior period volume adjustments made by the operators on several other wells during 2004, and (iii) normal declines in production. These decreases were partially offset by (i) positive prior period volume adjustments made by the operators on several wells during 2005, (ii) the successful completion of two new wells during late 2004, and (iii) an increase in production on one significant well following the successful 2004 workover of that well. The decrease in volumes of gas sold was primarily due to (i) a negative prior period volume adjustment made by the operator on one significant well during 2005, (ii) normal declines in production, and (iii) a positive prior period volume adjustment included in the receipt of first revenues on one significant well during 2004. These decreases were partially offset by (i) positive prior period volume adjustments made by the operators on -40- several wells during 2005 and (ii) negative prior period volume adjustments made by the operators on several other wells during 2004. The increase in production expenses was primarily due to (i) an increase in production taxes associated with the increase in oil and gas sales, (ii) workover expenses incurred in 2005 on several wells, and (iii) an increase in saltwater disposal expenses incurred on one significant unit during 2005 as compared to 2004. These increases were partially offset by workover expenses incurred on two significant wells during 2004. As of the date of this Annual Report, management anticipates that the saltwater disposal expenses on the significant unit will remain at 2005 levels. Average oil and gas prices increased to $51.56 per barrel and $6.60 per Mcf, respectively, in 2005 from $36.36 per barrel and $4.63 per Mcf, respectively, in 2004. Depletion of Net Profits Interests increased $12,000 (17.4%) in 2005 as compared to 2004. Of this increase (i) $11,000 was due to the depletion of additional Net Profits Interests as a result of the upward revision in the estimate of the asset retirement obligations, of which $6,000 was related to previously fully depleted wells and (ii) $3,000 was due to accretion of these additional asset retirement obligations. These increases were partially offset by the decreases in volumes of oil and gas sold. As a percentage of Net Profits, this expense decreased to 3.8% in 2005 from 4.6% in 2004, primarily due to the increases in the average prices of oil and gas sold. General and administrative expenses increased $6,000 (4.1%) in 2005 as compared to 2004. As a percentage of Net Profits, these expenses decreased to 7.0% in 2005 from 9.6% in 2004, primarily due to the increase in Net Profits. The Limited Partners have received cash distributions through December 31, 2005 totaling $18,204,558 or 168.45% of Limited Partners' capital contributions. Year Ended December 31, 2004 Compared to Year Ended December 31, 2003 -------------------------------------- Total Net Profits increased $111,000 (8.1%) in 2004 as compared to 2003. Of this increase (i) $155,000 and $94,000, respectively, were related to increases in the average prices of oil and gas sold and (ii) $21,000 was related to an increase in volumes of oil sold. These increases were partially offset by a decrease of (i) $140,000 related to a decrease in volumes of gas sold and (ii) $19,000 related to an increase in production expenses. -41- Volumes of oil sold increased 753 barrels, while volumes of gas sold decreased 32,961 Mcf in 2004 as compared to 2003. The increase in volumes of oil sold was primarily due to positive prior period volume adjustments made in 2004 by the operators on several wells. These increases were partially offset by normal declines in production. The decrease in volumes of gas sold was primarily due to (i) negative prior period volume adjustments made in 2004 by the operators on several wells and (ii) normal declines in production. The decreases in gas volumes were partially offset by the receipt of first revenues on one significant well during 2004. The increase in production expenses was primarily due to (i) workover expenses incurred on two significant wells during 2004, (ii) an increase in production taxes associated with the increase in oil and gas sales, and (iii) a 2004 increase in production taxes associated with the receipt of first revenues on one significant well. These increases were partially offset by (i) negative prior period production tax adjustments made by the operator on several wells during 2004, (ii) a decrease in lease operating expenses associated with the decrease in volumes of gas sold, and (iii) workover expenses incurred on several wells during 2003. Average oil and gas prices increased to $36.36 per barrel and $4.63 per Mcf, respectively, in 2004 from $28.35 per barrel and $4.25 per Mcf, respectively, in 2003. Depletion of Net Profits Interests decreased $12,000 (15.3%) in 2004 as compared to 2003. This decrease was primarily due to (i) upward revisions in the estimates of remaining oil and gas reserves during 2004 and (ii) the decrease in volumes of gas sold. As a percentage of Net Profits, this expense decreased to 4.6% in 2004 from 5.8% in 2003. This percentage decrease was primarily due to (i) the dollar decrease in depletion of Net Profits Interests and (ii) the increase in the average prices of oil and gas sold. General and administrative expenses remained relatively constant in 2004 and 2003. As a percentage of Net Profits, these expenses decreased to 9.6% in 2004 from 10.4% in 2003. -42- P-3 Partnership --------------- Year Ended December 31, 2005 Compared to Year Ended December 31, 2004 -------------------------------------- Total Net Profits increased $872,000 (39.9%) in 2005 as compared to 2004. Of this increase $363,000 and $710,000, respectively, were related to increases in the average prices of oil and gas sold. These increases were partially offset by decreases of (i) $33,000 and $120,000, respectively, related to decreases in volumes of oil and gas sold and (ii) $48,000 related to an increase in production expenses. Volumes of oil and gas sold decreased 893 barrels and 25,051 Mcf, respectively, in 2005 as compared to 2004. The decrease in volumes of oil sold was primarily due to (i) negative prior period volume adjustments made by the operators on several wells during 2005, (ii) similar positive prior period volume adjustments made by the operators on several other wells during 2004, and (iii) normal declines in production. These decreases were partially offset by (i) positive prior period volume adjustments made by the operators on several wells during 2005, (ii) the successful completion of two new wells during late 2004, and (iii) an increase in production on one significant well following the successful 2004 workover of that well. The decrease in volumes of gas sold was primarily due to (i) a negative prior period volume adjustment made by the operator on one significant well during 2005, (ii) normal declines in production, and (iii) a positive prior period volume adjustment included in the receipt of first revenues on one significant well during 2004. These decreases were partially offset by (i) positive prior period volume adjustments made by the operators on several wells during 2005 and (ii) similar negative prior period volume adjustments made by the operators on several other wells during 2004. The increase in production expenses was primarily due to (i) an increase in production taxes associated with the increase in oil and gas sales, (ii) workover expenses incurred on several wells during 2005, and (iii) an increase in saltwater disposal expenses incurred on one significant unit during 2005 as compared to 2004. These increases were partially offset by workover expenses incurred on two significant wells during 2004. As of the date of this Annual Report, management anticipates that the saltwater disposal expenses on the significant unit will remain at 2005 levels. Average oil and gas prices increased to $51.53 per barrel and $6.75 per Mcf, respectively, in 2005 from $36.42 per barrel and $4.80 per Mcf, respectively, in 2004. -43- Depletion of Net Profits Interests decreased $87,000 (42.3%) in 2005 as compared to 2004. This decrease was primarily due to (i) one significant well being fully depleted during 2004 due to the lack of remaining reserves and (ii) the decreases in volumes of oil and gas sold. These decreases were partially offset by (i) an increase of $15,000 due to the depletion of additional Net Profits Interests as a result of the upward revision in the estimate of the asset retirement obligations, of which $8,000 was related to previously fully depleted wells, (ii) an increase of $4,000 due to accretion of these additional asset retirement obligations, and (iii) one significant well being fully depleted during 2005 due to the lack of remaining reserves. As a percentage of Net Profits, this expense decreased to 3.9% in 2005 from 9.4% in 2004. This percentage decrease was primarily due to (i) the dollar decrease in Depletion of Net Profits Interests and (ii) the increases in the average prices of oil and gas sold. General and administrative expenses increased $6,000 (2.7%) in 2005 as compared to 2004. As a percentage of Net Profits, these expenses decreased to 7.0% in 2005 from 9.6% in 2004, primarily due to the increase in Net Profits. The Limited Partners have received cash distributions through December 31, 2005 totaling $25,490,401 or 150.26% of Limited Partners' capital contributions. Year Ended December 31, 2004 Compared to Year Ended December 31, 2003 -------------------------------------- Total Net Profits increased $194,000 (9.7%) in 2004 as compared to 2003. Of this increase (i) $201,000 and $162,000, respectively, were related to increases in the average prices of oil and gas sold and (ii) $28,000 was related to an increase in volumes of oil sold. These increases were partially offset by a decrease of (i) $159,000 related to a decrease in volumes of gas sold and (ii) $38,000 related to an increase in production expenses. Volumes of oil sold increased 990 barrels, while volumes of gas sold decreased 36,303 Mcf in 2004 as compared to 2003. The increase in volumes of oil sold was primarily due to positive prior period volume adjustments made by the operators on several wells during 2004, which increases were partially offset by normal declines in production. The decrease in volumes of gas sold was primarily due to (i) negative prior period volume adjustments made by the operators on several wells during 2004 and (ii) normal declines in production. These decreases were partially offset by the receipt of first revenues on one significant well during 2004. -44- The increase in production expenses was primarily due to (i) workover expenses incurred on two significant wells during 2004, (ii) an increase in production taxes associated with the increase in oil and gas sales, and (iii) an increase in production taxes associated with the receipt of first revenues on one significant well during 2004. These increases were partially offset by (i) negative prior period production tax adjustments made by the operator on several wells during 2004, (ii) a decrease in lease operating expenses associated with the decrease in volumes of gas sold, and (iii) workover expenses incurred on several wells during 2003. Average oil and gas prices increased to $36.42 per barrel and $4.80 per Mcf, respectively, in 2004 from $28.37 per barrel and $4.39 per Mcf, respectively, in 2003. Depletion of Net Profits Interests increased $84,000 (69.0%) in 2004 as compared to 2003. This increase was primarily due to one significant well becoming fully depleted during 2004 due to the lack of remaining reserves. This increase was partially offset by (i) upward revisions in the estimates of remaining oil and gas reserves during 2004 and (ii) the decrease in volumes of gas sold. As a percentage of Net Profits, this expense increased to 9.4% in 2004 from 6.1% in 2003. This percentage increase was primarily due to the dollar increase in depletion of Net Profits Interests. General and administrative expenses remained relatively constant in 2004 and 2003. As a percentage of Net Profits, these expenses decreased to 9.6% in 2004 from 10.6% in 2003. P-4 Partnership --------------- Year Ended December 31, 2005 Compared to Year Ended December 31, 2004 -------------------------------------- Total Net Profits increased $161,000 (9.6%) in 2005 as compared to 2004. Of this increase $225,000 and $369,000, respectively, were related to increases in the average prices of oil and gas sold. These increases were partially offset by decreases of (i) $78,000 and $220,000, respectively, related to decreases in volumes of oil and gas sold and (ii) $135,000 related to an increase in production expenses. Volumes of oil and gas sold decreased 1,948 barrels and 38,364 Mcf, respectively, in 2005 as compared to 2004. The decrease in volumes of oil sold was primarily due to (i) normal declines in production and (ii) the shutting-in of one significant well during late 2004 and early 2005 in order to perform a workover. As of the date of this Annual Report, the -45- shut-in well has returned to production at a lower rate than previously experienced. The lower production rate is expected to continue. The decrease in volumes of gas sold was primarily due to (i) normal declines in production, (ii) a positive prior period volume adjustment included in the receipt of first revenues on one significant well during 2004, and (iii) the shutting-in of two significant wells during early 2005 in order to perform workovers. As of the date of this Annual Report, the operator has not yet determined when or if the shut-in wells will return to production, and if returned to production, at what rate. The increase in production expenses was primarily due to (i) workover expenses incurred on several wells during 2005, (ii) an increase in production taxes associated with the increase in oil and gas sales, and (iii) a positive prior period production tax adjustment made by the operator on one significant well during 2005. Average oil and gas prices increased to $54.22 per barrel and $7.60 per Mcf, respectively, in 2005 from $39.91 per barrel and $5.75 per Mcf, respectively, in 2004. Depletion of Net Profits Interests increased $5,000 (5.7%) in 2005 as compared to 2004. Of this increase (i) $32,000 was due to the depletion of additional Net Profits Interests as a result of the upward revision in the estimate of the asset retirement obligations, of which $20,000 was related to previously fully depleted wells, and (ii) $4,000 was due to accretion of these additional asset retirement obligations. These increases were partially offset by (i) the abandonment of one significant well during 2004 following an unsuccessful recompletion attempt and (ii) the decreases in volumes of oil and gas sold. As a percentage of Net Profits, this expense decreased to 4.6% in 2005 from 4.7% in 2004. General and administrative expenses increased $7,000 (4.2%) in 2005 as compared to 2004. As a percentage of Net Profits, these expenses decreased to 9.2% in 2005 from 9.7% in 2004. Cumulative cash distributions to the Limited Partners through December 31, 2005 were $20,214,945 or 160.05% of Limited Partners' capital contributions. Year Ended December 31, 2004 Compared to Year Ended December 31, 2003 -------------------------------------- Total Net Profits increased $94,000 (6.0%) in 2004 as compared to 2003. Of this increase $181,000 and $130,000, respectively, were related to increases in the average prices of -46- oil and gas sold. These increases were partially offset by decreases of (i) $111,000 and $105,000, respectively, related to decreases in volumes of oil and gas sold and (ii) $1,000 related to an increase in production expenses. Volumes of oil and gas sold decreased 3,752 barrels and 20,147 Mcf, respectively, in 2004 as compared to 2003. The decrease in volumes of oil sold was primarily due to (i) normal declines in production and (ii) the shutting in of one significant well during late 2004 due to mechanical problems. The decrease in volumes of gas sold was primarily due to normal declines in production, which decrease was partially offset by the receipt of first revenues on one significant well during 2004. The increase in production expenses was primarily due to (i) an increase in production taxes associated with the increase in oil and gas sales, (ii) workover expenses incurred on several wells during 2004, and (iii) an increase in production taxes associated with the receipt of first revenues on one significant well during 2004. These increases were partially offset by a decrease in lease operating expense associated with the decreases in volumes of oil and gas sold. Average oil and gas prices increased to $39.91 per barrel and $5.75 per Mcf, respectively, in 2004 from $29.66 per barrel and $5.21 per Mcf, respectively, in 2003. Depletion of Net Profits Interests decreased $13,000 (14.6%) in 2004 as compared to 2003. This decrease was primarily due to (i) upward revisions in the estimates of remaining oil and gas reserves during 2004 and (ii) the decreases in volumes of oil and gas sold. These decreases were partially offset by the abandonment of one significant well during 2004 following an unsuccessful recompletion attempt. As a percentage of Net Profits, this expense decreased to 4.7% in 2004 from 5.9% in 2003. This percentage decrease was primarily due to (i) the dollar decrease in depletion of Net Profits Interests and (ii) the increase in the average prices of oil and gas sold. General and administrative expenses remained relatively constant in 2004 and 2003. As a percentage of Net Profits, these expenses decreased to 9.7% in 2004 from 10.2% in 2003. -47- P-5 Partnership --------------- Year Ended December 31, 2005 Compared to Year Ended December 31, 2004 -------------------------------------- Total Net Profits increased $345,000 (27.6%) in 2005 as compared to 2004. Of this increase (i) $70,000 and $494,000, respectively, were related to increases in the average prices of oil and gas sold and (ii) $3,000 was related to an increase in volumes of oil sold. These increases were partially offset by decreases of (i) $162,000 related to a decrease in volumes of gas sold and (ii) $60,000 related to an increase in production expenses. Volumes of oil sold increased 79 barrels, while volumes of gas sold decreased 31,893 Mcf in 2005 as compared to 2004. The increase in volumes of oil sold was primarily due to (i) positive prior period volume adjustments made by the operators on several wells during 2005 and (ii) the successful completion of several new wells during mid 2004 and early and mid 2005. These increases were partially offset by normal declines in production. The decrease in volumes of gas sold was primarily due to (i) normal declines in production, (ii) a negative prior period volume adjustment on one significant well during 2005, and (iii) a substantial decline in production during 2005 on one significant well following a workover of that well during late 2004. This well is not expected to return to its previously high levels of production. The decreases in volumes of gas sold were partially offset by the successful completion of several new wells during mid to late 2004 and early 2005. The increase in production expenses was primarily due to (i) workover expenses incurred on several wells during 2005 and (ii) an increase in production taxes associated with the increase in oil and gas sales. These increases were partially offset by workover expenses incurred on several other wells during 2004. Average oil and gas prices increased to $53.42 per barrel and $7.04 per Mcf, respectively, in 2005 from $38.44 per barrel and $5.08 per Mcf, respectively, in 2004. Depletion of Net Profits Interests increased $12,000 (12.8%) in 2005 as compared to 2004. Of this increase (i) $23,000 was due to the depletion of additional Net Profits Interests as a result of the upward revision in the estimate of the asset retirement obligations, of which $16,000 was related to previously fully depleted wells and (ii) $3,000 was due to accretion of these additional asset retirement obligations. This increase was also due to an increase in depletable Net Profits -48- Interests during 2005 primarily due to the drilling of two developmental wells. These increases were partially offset by (i) the decrease in volumes of gas sold, (ii) one significant well being fully depleted during 2004 due to the lack of remaining reserves, and (iii) upward revisions in the estimates of remaining oil and gas reserves since December 31, 2004. As a percentage of Net Profits, this expense decreased to 6.7% in 2005 from 7.6% in 2004, primarily due to the increases in the average prices of oil and gas sold. General and administrative expenses increased $7,000 (4.5%) in 2005 as compared to 2004. As a percentage of Net Profits, these expenses decreased to 10.0% in 2005 from 12.2% in 2004, primarily due to the increase in Net Profits. Cumulative cash distributions to the Limited Partners through December 31, 2005 were $14,257,759 or 120.37% of Limited Partners' capital contributions. Year Ended December 31, 2004 Compared to Year Ended December 31, 2003 -------------------------------------- Total Net Profits decreased $34,000 (2.6%) in 2004 as compared to 2003. Of this decrease (i) $53,000 and $142,000, respectively, were related to decreases in volumes of oil and gas sold and (ii) $2,000 was related to an increase in production expenses. These decreases were partially offset by increases of $39,000 and $124,000, respectively, related to increases in the average prices of oil and gas sold. Volumes of oil and gas sold decreased 1,761 barrels and 30,660 Mcf, respectively, in 2004 as compared to 2003. The decrease in volumes of oil sold was primarily due to (i) the shutting-in of a producing zone on one significant well during late 2003 and (ii) normal declines in production. The decrease in volumes of gas sold was primarily due to (i) downward revisions in the estimates of remaining gas reserves on one significant well resulting in the P-5 Partnership becoming over produced in excess of estimated ultimate reserves thereby increasing gas imbalance payable and (ii) normal declines in production. These decreases were partially offset by the successful completion of one significant well during early 2004. The increase in production expense was primarily due to workover expenses incurred on several wells during 2004, which increase was substantially offset by a decrease in lease operating expenses associated with the decreases in volumes of oil and gas sold. Average oil and gas prices increased to $38.44 per barrel and $5.08 per Mcf, respectively, in 2004 from $30.01 per barrel and $4.64 per Mcf, respectively, in 2003. -49- Depletion of Net Profits Interests increased $15,000 (19.2%) in 2004 as compared to 2003. This increase was primarily due to (i) an increase in depletable Net Profits Interests primarily due to developmental drilling activities on several properties during 2004 and (ii) one significant well being fully depleted in 2004 due to the lack of remaining reserves. These increases were partially offset by the decrease in volumes of oil and gas sold. As a percentage of Net Profits, this expense increased to 7.6% in 2004 from 6.2% in 2003. This percentage increase was primarily due to the dollar increase in depletion of Net Profits Interests. General and administrative expenses remained relatively constant in 2004 and 2003. As a percentage of Net Profits, these expenses increased to 12.2% in 2004 from 11.9% in 2003. P-6 Partnership --------------- Year Ended December 31, 2005 Compared to Year Ended December 31, 2004 -------------------------------------- Total Net Profits increased $746,000 (40.0%) in 2005 as compared to 2004. Of this increase (i) $113,000 and $673,000, respectively, were related to increases in the average prices of oil and gas sold and (ii) $131,000 was related to an increase in volumes of oil sold. These increases were partially offset by a decrease of $171,000 related to a decrease in volumes of gas sold. Volumes of oil sold increased 3,057 barrels, while volumes of gas sold decreased 31,961 Mcf in 2005 as compared to 2004. The increase in volumes of oil sold was primarily due to (i) a negative prior period volume adjustment made in 2004 by the operator on one significant well and (ii) the successful completion of several new wells during early to mid 2005. The decrease in volumes of gas sold was primarily due to (i) normal declines in production, (ii) a substantial decline in production during 2005 on one significant well following a workover of that well during mid 2005, and (iii) a negative prior period volume adjustment on one significant well during 2005. The well with a substantial decline in production is not expected to return to its previous levels of production. The decreases in volumes of gas sold were partially offset by (i) a negative prior period volume adjustment made in 2004 by the operator on another significant well and (ii) the successful completion of several wells during mid to late 2004 and early 2005. Increases in production expenses were primarily due to (i) an increase in production taxes associated with the increase in oil and gas sales and (ii) workover expenses incurred on several wells during 2005. These increases were substantially offset by -50- (i) a prior period production tax adjustment on one significant unit during 2004, (ii) workover expenses incurred on two significant wells during 2004, and (iii) the abandonment of one significant well during 2004 due to severe mechanical problems. Average oil and gas prices increased to $53.44 per barrel and $6.96 per Mcf, respectively, in 2005 from $43.01 per barrel and $5.33 per Mcf, respectively, in 2004. Depletion of Net Profits Interests increased $176,000 (145.5%) in 2005 as compared to 2004. Of this increase (i) $86,000 was due to the depletion of additional Net Profits Interests as a result of the upward revision in the estimate of the asset retirement obligations, of which $64,000 was related to previously fully depleted wells, and (ii) $10,000 was due to accretion of these additional asset retirement obligations. This increase was also due to downward revisions in the estimates of remaining oil and gas reserves following an unsuccessful recompletion attempt on one significant well during 2005. These increases were partially offset by one significant well being fully depleted during 2004 due to the lack of remaining reserves. As a percentage of Net Profits, this expense increased to 11.4% in 2005 from 6.5% in 2004, primarily due to the dollar increase in depletion of Net Profits Interests. General and administrative expenses increased $7,000 (3.7%) in 2005 as compared to 2004. As a percentage of Net Profits, these expenses decreased to 7.1% in 2005 from 9.6% in 2004, primarily due to the increase in Net Profits. The Limited Partners have received cash distributions through December 31, 2005 totaling $20,991,248 or 146.75% of Limited Partners' capital contributions. Year Ended December 31, 2004 Compared to Year Ended December 31, 2003 -------------------------------------- Total Net Profits decreased $483,000 (20.6%) in 2004 as compared to 2003. Of this decrease (i) $234,000 and $597,000, respectively, were related to decreases in volumes of oil and gas sold and (ii) $102,000 was related to an increase in production expenses. These decreases were partially offset by increases of $110,000 and $340,000, respectively, related to increases in the average prices of oil and gas sold. Volumes of oil and gas sold decreased 8,115 barrels and 130,618 Mcf, respectively, in 2004 as compared to 2003. The decrease in volumes of oil sold was primarily due to (i) a negative prior period volume adjustment made by the operator on one significant well during 2004, (ii) normal declines in production, and (iii) the shutting-in of a producing zone on one -51- other significant well during late 2003. The decrease in volumes of gas sold was primarily due to (i) normal declines in production, (ii) downward revisions in the estimates of remaining gas reserves on one significant well resulting in the P-6 Partnership becoming over produced in excess of estimated ultimate reserves thereby increasing gas imbalance payable, and (iii) a negative prior period volume adjustment made on one significant well during 2004. The increase in production expenses was primarily due to (i) a prior period production tax adjustment on one significant unit during 2004, (ii) workover expenses incurred on two significant wells during 2004, and (iii) the abandonment of one significant well during 2004 due to severe mechanical problems. These increases were partially offset by a decrease in lease operating expenses associated with the decreases in volumes of oil and gas sold. Average oil and gas prices increased to $43.01 per barrel and $5.33 per Mcf, respectively, in 2004 from $28.89 per barrel and $4.57 per Mcf, respectively, in 2003. Depletion of Net Profits Interests decreased $22,000 (15.6%) in 2004 as compared to 2003. This decrease was primarily due to the decreases in volumes of oil and gas sold, which decrease was partially offset by one significant well being fully depleted during 2004 due to the lack of remaining reserves. As a percentage of Net Profits, this expense increased to 6.3% in 2004 from 6.1% in 2003. General and administrative expenses remained relatively constant in 2004 and 2003. As a percentage of Net Profits, these expenses increased to 9.4% in 2004 from 7.7% in 2003, primarily due to the decrease in Net Profits. -52- Average Proceeds and Units of Production The following tables are comparisons of the annual barrel of oil equivalent ("boe") (one barrel of oil or six Mcf of gas) and the average proceeds (oil and gas sales less lease operating expenses and production taxes) received per boe attributable to the Partnerships' Net Profits for the years ended December 31, 2005, 2004, and 2003. 2005 Compared to 2004 --------------------- Average Proceeds per BOE BOE ----------------------------- -------------------------- P/ship 2005 2004 % Change 2005 2004 % Change ------ ------- ------- -------- ------ ------ -------- P-1 58,371 61,343 ( 5%) $36.12 $24.14 50% P-3 84,774 89,842 ( 6%) 36.09 24.34 48% P-4 49,087 57,429 (15%) 37.24 29.03 28% P-5 46,529 51,765 (10%) 34.21 24.09 42% P-6 79,972 82,242 ( 3%) 32.64 22.67 44% 2004 Compared to 2003 --------------------- Average Proceeds per BOE BOE ----------------------------- -------------------------- P/ship 2004 2003 % Change 2004 2003 % Change ------ ------- ------- -------- ------ ------ -------- P-1 61,343 66,083 ( 7%) $24.14 $20.73 16% P-3 89,842 94,902 ( 5%) 24.34 21.00 16% P-4 57,429 64,539 (11%) 29.03 24.37 19% P-5 51,765 58,636 (12%) 24.09 21.84 10% P-6 82,242 112,126 (27%) 22.67 20.93 8% Liquidity and Capital Resources Net proceeds from operations less necessary operating capital are distributed to the Limited Partners on a quarterly basis. See "Item 5. Market for Units and Related Limited Partner Matters." The net proceeds from the Net Profits Interests are generally not reinvested in productive assets. Assuming 2005 production levels for future years, the Partnerships' proved reserve quantities at December 31, 2005 would have the following remaining lives: -53- Partnership Gas-Years Oil-Years ----------- --------- --------- P-1 9.2 12.9 P-3 9.5 13.2 P-4 9.1 3.0 P-5 8.8 8.6 P-6 8.0 11.6 These life of reserves estimates are based on the current estimates of remaining oil and gas reserves. See "Item 2. Properties" for a discussion of these reserve estimates. Any decrease from the high oil and gas prices at December 31, 2005 may cause a decrease in the estimated life of said reserves. As discussed below, the Partnerships must terminate no later than December 31, 2015 (ten years after December 31, 2005). The Partnerships' available capital from the Limited Partners' subscriptions has been spent on Net Profits Interests and there should be no further material capital resource commitments in the future. The Partnerships have no debt commitments. Expenditures by the Affiliated Programs for new wells, well recompletions, or workovers, however, may reduce or eliminate cash available for a particular quarterly cash distribution. During 2005, capital expenditures affecting the P-6 Partnership's Net Profits Interests totaled approximately $213,000. These costs were indirectly incurred primarily as a result of recompletion activities on (i) the Henderson Stovall GU #2 well located in Wharton County, Texas and (ii) the Berniece 1 well located in Grayson County, Texas. Other capital expenditures incurred by the Partnerships during 2005 were not material to the Partnerships' cash flows. The Partnerships sold certain Net Profits Interests during 2004 and 2003. No such sales occurred during 2005. These sales were made by the General Partner after giving due consideration to both the offer price and the General Partner's estimate of the underlying property's remaining proved reserves and future operating costs. Net proceeds from the sales were distributed to the Partnerships and included in the calculation of the Partnerships' cash distributions for the quarter immediately following the Partnerships' receipt of the proceeds. The amount of such proceeds from the sale of Net Profits Interest during 2005, 2004, and 2003, were as follows: -54- Partnership 2005 2004 2003 ----------- ------ ------- ------- P-1 $ - $16,707 $45,230 P-3 - 21,366 57,301 P-4 - 434 938 P-5 - - 8,657 P-6 - - 5,212 Over the years, as part of the normal course of business, some of the Partnerships' interests in wells have been sold, generally at oil and gas auctions. Given the generally favorable current environment for oil and gas dispositions, it is possible that the Partnerships will increase the number of properties to be sold. In the event of sales, any net proceeds are distributed as soon as possible after the disposition. Future production, costs, and cash flow will be reduced as properties are sold. There can be no assurance as to the amount of the Partnerships' future cash distributions. The Partnerships' ability to make cash distributions depends primarily upon the level of available cash flow generated by the Partnerships' Net Profits Interests, which will be affected (either positively or negatively) by many factors beyond the control of the Partnerships, including the price of and demand for oil and gas and other market and economic conditions. Even if prices and costs remain stable, the amount of cash available for distributions will decline over time (as the volume of production from producing properties declines) since the Partnerships are not generally replacing production. The General Partner expects general and administrative expenses to increase substantially during 2006 and 2007 due to costs required to comply with Section 404 of the Sarbanes-Oxley Act of 2002. Such anticipated increase will reduce cash available for distribution. The General Partner expects at least a portion of this anticipated increase in general and administrative expenses to continue in years beyond 2007. Pursuant to the terms of the Partnership Agreements, the Partnerships would have terminated on December 31, 2005. However, the Partnership Agreements provide that the General Partner may extend the term of each Partnership for up to five periods of two years each. The General Partner has extended the terms of the Partnerships for the first two-year extension period to December 31, 2007. As of the date of this Annual Report, the General Partner has not determined whether to further extend the term of any Partnership. Off-Balance Sheet Arrangements The Partnerships do not have any off-balance sheet arrangements. -55- Tabular Disclosure of Contractual Obligations The Partnerships do not have any contractual obligations of the type required to be disclosed under this heading. Critical Accounting Policies The Partnerships follow the successful efforts method of accounting for their Net Profits Interests. Under the successful efforts method, the Partnerships capitalize all acquisition costs. Such acquisition costs include costs incurred by the Partnerships or the General Partner to acquire a Net Profits Interest, including related title insurance or examination costs, commissions, engineering, legal and accounting fees, and similar costs directly related to the acquisitions plus an allocated portion of the General Partner's property screening costs. The net acquisition cost to the Partnerships of the Net Profits Interests in properties acquired by the General Partner consists of the cost of acquiring the underlying properties adjusted for the net cash results of operations, including any interest incurred to finance the acquisition, for the period of time the properties are held by the General Partner. Depletion of the cost of Net Profits Interests is computed on the units-of-production method. The Partnerships' calculation of depletion of its Net Profits Interests includes estimated dismantlement and abandonment costs, net of estimated salvage values related to the underlying properties in which the Partnership has a Net Profits Interest. The Partnerships evaluate the recoverability of the carrying costs of their Net Profits Interests in proved oil and gas properties for each oil and gas field (rather than separately for each well). If the unamortized costs of a Net Profits Interest within a field exceeds the expected undiscounted future cash flows from such Net Profits Interest, the cost of the Net Profits Interest is written down to fair value, which is determined by using the discounted future cash flows from the Net Profits Interest. Revenues from a Net Profits Interest consist of a share of the oil and gas sales of the property, less operating and production expenses. The Partnerships accrue for oil and gas revenues less expenses from the Net Profits Interests. Sales of gas applicable to the Net Profits Interests are recorded as revenue when the gas is metered and title transferred pursuant to the gas sales contracts. During such times as sales of gas exceed a Partnership's pro rata Net Profits Interest in a well, such sales are recorded as revenue unless total sales from the well have exceeded the Partnership's share of estimated total gas reserves attributable to the underlying property, at which time such excess is recorded as a liability. The rates per Mcf used -56- to calculate this liability are based on the average gas price for which the Partnerships are currently settling this liability. This liability is recorded as a reduction of accounts receivable. Also included in accounts receivable(payable)-Net Profits are amounts which represent costs deferred or accrued for Net Profits relating to lease operating expenses incurred in connection with the net underproduced or overproduced gas imbalance positions. The rate used in calculating the deferred charge or accrued liability is the average annual production costs per Mcf. Asset Retirement Obligation The Partnerships' wells must be properly plugged and abandoned after their oil and gas reserves are exhausted. The Partnerships follow FAS No. 143, "Accounting for Asset Retirement Obligations" in accounting for the future expenditures that will be necessary to plug and abandon these wells. FAS No. 143 requires the estimated plugging and abandonment obligations to be recognized in the period in which they are incurred (i.e. when the well is drilled or acquired) if a reasonable estimate of fair value can be made and to be capitalized as part of the carrying amount of the well. New Accounting Pronouncements The Partnerships are not aware of any recently issued accounting pronouncements that would have an impact on the Partnerships' future results of operations and financial position. Inflation and Changing Prices Prices obtained for oil and gas production depend upon numerous factors, including the extent of domestic and foreign production, foreign imports of oil, market demand, domestic and foreign economic conditions in general, and governmental regulations and tax laws. Inflationary pressure on drilling and operating costs have impacted the operating and drilling costs incurred by the Partnerships. This pressure is expected to continue to the extent commodity prices remain at their current levels. Oil and gas prices have fluctuated during recent years and generally have not followed the same pattern as inflation. See "Item 2.

CONTROLS AND PROCEDURES As of the end of the period covered by this report, the principal executive officer and principal financial officer conducted an evaluation of the Partnerships' disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934). Based on this evaluation, such officers concluded that the Partnerships' disclosure controls and procedures are effective to ensure that information required to be disclosed by the Partnerships in reports filed under the Exchange Act is recorded, processed, summarized, and reported accurately and within the time periods specified in the Securities and Exchange Commission rules and forms. ITEM 9B. OTHER INFORMATION The General Partner is not aware of any information required to be reported on Form 8-K during the fourth quarter of 2005 but which was not so reported. PART III. ITEM 10.

The following individuals are directors and executive officers of the General Partner. The business address of such director and executive officers is Two West Second Street, Tulsa, Oklahoma 74103. -58- Name Age Position with General Partner ---------------- --- -------------------------------- Dennis R.

Fox 55 Secretary The director will hold office until the next annual meeting of shareholders of Geodyne or until his successor has been duly elected and qualified.

Prior to joining Samson, he was associated with a Tulsa law firm, Conner and Winters, where his principal practice was in the securities area.

Ms. Fox is also Secretary of Berry Gas Company, Circle L Drilling Company, Compression, Inc., Dyco Petroleum Corporation, Samson Hydrocarbons Company, Snyder Exploration Company, and Samson Properties Incorporated. Section 16(a) Beneficial Ownership Reporting Compliance To the best knowledge of the Partnerships and the General Partner, there were no officers, directors, or ten percent owners who were delinquent filers during 2005 of reports required under Section 16 of the Securities Exchange Act of 1934. Audit Committee Financial Expert The Partnerships are not required by SEC regulations or otherwise to maintain an audit committee. The board of directors of the General Partner consists of one person and therefore serves as its audit committee. There is not an audit committee financial expert, as defined in the SEC regulations, serving on the General Partner's board of directors. -59- Code of Ethics The General Partner has adopted a Code of Ethics which applies to all of its executive officers, including those persons who perform the functions of principal executive officer, principal financial officer, and principal accounting officer. The Partnerships will provide, free of charge, a copy of this Code of Ethics to any person upon receipt of a written request mailed to Geodyne Resources, Inc., Samson Plaza, Two West Second Street, Tulsa, OK 74103. Such request must include the address to which the Code of Ethics should be mailed. ITEM 11. EXECUTIVE COMPENSATION The General Partner and its affiliates are reimbursed for actual general and administrative costs and operating costs incurred and attributable to the conduct of the business affairs and operations of the Partnerships, computed on a cost basis, determined in accordance with generally accepted accounting principles. Such reimbursed costs and expenses allocated to the Partnerships include office rent, secretarial, employee compensation and benefits, travel and communication costs, fees for professional services, and other items generally classified as general or administrative expense. When actual costs incurred benefit other Partnerships and affiliates, the allocation of costs is based on the relationship of the Partnerships' reserves to the total reserves owned by all Partnerships and affiliates. The amount of general and administrative expense allocated to the General Partner and its affiliates and charged to each Partnership during 2005, 2004, and 2003, is set forth in the table below. Although the actual costs incurred by the General Partner and its affiliates have fluctuated during the three years presented, the amounts charged to the Partnerships have not fluctuated due to expense limitations imposed by the Partnership Agreements. Partnership 2005 2004 2003 ----------- -------- -------- -------- P-1 $113,760 $113,760 $113,760 P-3 178,560 178,560 178,560 P-4 132,960 132,960 132,960 P-5 124,680 124,680 124,680 P-6 150,564 150,564 150,564 None of the officers or directors of the General Partner receive compensation directly from the Partnerships. The Partnerships reimburse the General Partner or its affiliates for that portion of such officers' and directors' salaries and expenses attributable to time devoted by such individuals to the Partnerships' activities based on the allocation method described above. The following tables indicate the approximate amount of general and administrative expense reimbursement attributable to the salaries of the directors, officers, and employees of the General Partner and its affiliates during 2005, 2004, and 2003: -60- Salary Reimbursements P-1 Partnership --------------- Three Years Ended December 31, 2005 Long Term Compensation ---------------------------------- Annual Compensation Awards Payouts ----------------------------- ----------------------- ------- Securi- Other ties All Name Annual Restricted Under- Other and Compen- Stock lying LTIP Compen- Principal Salary Bonus sation Award(s) Options/ Payouts sation Position Year ($) ($) ($) ($) SARs(#) ($) ($) - --------------- ---- ------- ------- ------- ---------- -------- ------- ------- Dennis R.

The owners of the working interests in these wells contract with such affiliates for services as operator of the wells. As operator, such affiliates are compensated at rates provided in the operating agreements in effect and charged to all parties to such agreement. Such compensation may occur both prior and subsequent to the commencement of commercial marketing of production of oil or gas. The dollar amount of such compensation which burdens the Partnerships' Net Profits Interests is impossible to quantify as of the date of this Annual Report. Samson maintains necessary inventories of new and used field equipment. Samson may have provided some of this equipment for wells in which the Partnerships have a Net Profits Interest. This equipment was provided at prices or rates equal to or less than those normally charged in the same or comparable geographic area by unaffiliated persons or companies dealing at arm's length. ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT The following table provides information as to the beneficial ownership of the Units as of the date of filing this Annual Report by (i) each beneficial owner of more than five percent of the issued and outstanding Units, (ii) the director and officers of the General Partner, and (iii) the General Partner and its affiliates. The address of the General Partner, its officers and director, and Samson Resources Company is Samson Plaza, Two West Second Street, Tulsa, Oklahoma 74103. Number of Units Beneficially Owned (Percent Beneficial Owner of Outstanding) - -------------------------------------------- --------------- P-1 Partnership: - --------------- Samson Resources Company 32,153 (29.8%) All affiliates, directors, and officers of the General Partner as a group and the General Partner (4 persons) 32,153 (29.8%) -66- P-3 Partnership: - --------------- Samson Resources Company 71,226 (42.0%) All affiliates, directors, and officers of the General Partner as a group and the General Partner (4 persons) 71,226 (42.0%) P-4 Partnership: - --------------- Samson Resources Company 35,021 (27.7%) All affiliates, directors, and officers of the General Partner as a group and the General Partner (4 persons) 35,021 (27.7%) P-5 Partnership: - --------------- Samson Resources Company 31,195 (26.3%) All affiliates, directors, and officers of the General Partner as a group and the General Partner (4 persons) 31,195 (26.3%) P-6 Partnership: - --------------- Samson Resources Company 21,881 (15.3%) ATL, Inc. 1200 Harbor Boulevard, 5th Floor Weehawken, NJ 07087 54,887 (38.4%) All affiliates, directors, and officers of the General Partner as a group and the General Partner (4 persons) 21,881 (15.3%) ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS The General Partner and certain of its affiliates engage in oil and gas activities independently of the Partnerships which result in conflicts of interest that cannot be totally eliminated. The allocation of acquisition opportunities and the nature of the compensation arrangements between the Partnerships and the General Partner also create potential conflicts of interest. An affiliate of the Partnerships owns some of the Partnerships' Units and therefore has an identity of interest -67- with other Limited Partners with respect to the operations of the Partnerships. In order to attempt to assure limited liability for the Limited Partners as well as an orderly conduct of business, management of the Partnerships is exercised solely by the General Partner. The Partnership Agreements grant the General Partner broad discretionary authority with respect to the Partnerships' expenditure and control of funds, including borrowings. These provisions are similar to those contained in prospectuses and partnership agreements for other public oil and gas partnerships. Broad discretion as to general management of the Partnerships involves circumstances where the General Partner has conflicts of interest and where it must allocate costs and expenses, or opportunities, among the Partnerships and other competing interests. The General Partner does not devote all of its time, efforts, and personnel exclusively to the Partnerships. Furthermore, the Partnerships do not have any employees, but instead rely on the personnel of Samson. The Partnerships thus compete with Samson (including other oil and gas partnerships) for the time and resources of such personnel. Samson devotes such time and personnel to the management of the Partnerships as are indicated by the circumstances and as are consistent with the General Partner's fiduciary duties. Affiliates of the Partnerships operate certain wells in which the Partnerships have a net profits interest and are compensated for such services at rates comparable to charges of unaffiliated third parties for services in the same geographic area. These costs are charged to the owners of the working interest of such wells and are considered when calculating the Net Profits payable to the Partnerships. These costs are thus indirectly borne by the Partnership. Affiliates of the Partnerships are solely responsible for the negotiation, administration, and enforcement of oil and gas sales agreements covering the leasehold interests in which the Partnerships hold Net Profits Interests. Because affiliates of the Partnerships who provide services to the owners of the Working Interests have fiduciary or other duties to other members of Samson, contract amendments and negotiating positions taken by them in their effort to enforce contracts with purchasers may not necessarily represent the positions that the owners of such Working Interests would take if they were to administer their own contracts without involvement with other members of Samson. On the other hand, management believes that the negotiating strength and contractual positions of the owners of such Working Interests have been enhanced by virtue of their affiliation with Samson. -68- ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES Audit Fees During 2005 and 2004, each Partnership paid the following audit fees: 2005 2004 ------- ------- Year-end audit per engagement letter $23,716 $21,560 1st quarter 10-Q review 925 825 2nd quarter 10-Q review 917 825 3rd quarter 10-Q review 917 825 Audit-Related Fees During 2005 and 2004 the Partnerships did not pay any audit-related fees of the type required by the SEC to be disclosed in this Annual Report under this heading. Tax Fees During 2005 and 2004 the Partnerships did not pay any tax compliance, tax advice, or tax planning fees of the type required by the SEC to be disclosed in this Annual Report under this heading. All Other Fees During 2005 and 2004 the Partnerships did not pay any other fees of the type required by the SEC to be disclosed in this Annual Report under this heading. Audit Approval The Partnerships do not have audit committee pre-approval policies and procedures as described in paragraph (c)(7)(i) of Rule 2-01 of Regulation S-X. The Partnerships did not receive any services of the type described in Items 9(e)(2) through 9(e)(4) of Schedule 14A. Audit and Related Fees Paid by Affiliates The Partnerships' accountants received compensation from other related partnerships managed by the General Partner and from other entities affiliated with the General Partner. This compensation is for audit services, tax related services, and other accounting-related services. The General Partner does not believe this arrangement creates a conflict of interest or -69- impairs the auditors' independence. PART IV. ITEM 15.

These financial statements are the responsibility of the Partnerships' management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. As discussed in Note 1 of Notes to the Combined Financial Statements under the heading "Asset Retirement Obligation", effective January 1, 2003 the Partnerships changed the manner in which they account for asset retirement obligations.

F-30 GEODYNE INSTITUTIONAL/PENSION PROGRAM Notes to the Combined Financial Statements For the Periods Ended December 31, 2005, 2004, and 2003 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Organization and Nature of Operations The Geodyne Institutional/Pension Energy Income Limited Partnerships (the "Partnerships") were formed pursuant to a public offering of depositary units ("Units"). Upon formation, investors became limited partners (the "Limited Partners") and held Units issued by each Partnership. Geodyne Resources, Inc. ("Geodyne") is the general partner of each of the Partnerships. Each Partnership is a general partner in the related Geodyne NPI Partnership (the "NPI Partnerships") in which Geodyne serves as the managing partner. Limited Partners' capital contributions were contributed to the related NPI Partnerships for investment in net profits interests, royalty interests, and other nonoperating interests in producing oil and gas properties. Most of the net profits interests acquired by the Partnerships have been carved out of working interests in producing properties, located in the continental United States, which were acquired by affiliated oil and gas investment programs (the "Affiliated Programs"). Net profits interests entitle the Partnerships to a share of net revenues from producing properties measured by a specific percentage of the net profits realized by such Affiliated Programs as owners of the working interests in the producing properties. Except where otherwise noted, references to certain operational activities of the Partnerships are actually the activities of the Affiliated Programs. As the holder of a net profits interest, a Partnership is not liable to pay any amount by which oil and gas operating costs and expenses exceed revenues for any period, although any deficit, together with interest, is applied to reduce the amounts payable to the Partnership in subsequent periods. As used in these financial statements, the Partnerships' net profits and royalty interests in oil and gas sales are referred to as "Net Profits" and the Partnerships' net profits and royalty interests in oil and gas properties are referred to as "Net Profits Interests." The Partnerships do not directly bear capital costs. However, the Partnerships indirectly bear certain capital costs incurred by the Affiliated Programs to the extent such capital costs are charged against the applicable oil and gas revenues in calculating the net profits payable to the Partnerships. For financial reporting purposes, such capital costs are reported as capital expenditures in the Partnerships' Statements of Cash Flows. The Partnerships were activated on the following dates with the following Limited Partner capital contributions: F-31 Limited Partner Date of Capital Partnership Activation Contributions ----------- ----------------- --------------- P-1 October 25, 1988 $10,807,400 P-3 May 10, 1989 16,963,700 P-4 November 21, 1989 12,630,600 P-5 February 27, 1990 11,844,900 P-6 September 5, 1990 14,304,100 The Partnerships' original termination date under their partnership agreements was December 31, 2005. The General Partner may extend the terms of the Partnerships for up to five two-year extension periods. The General Partner has extended the terms of the Partnerships for their first two-year period to December 31, 2007. The General Partner has not determined whether it will further extend the terms of any Partnership. For purposes of these financial statements, the Partnerships and NPI Partnerships are collectively referred to as the "Partnerships" and the general partner and managing partner are collectively referred to as the "General Partner". An affiliate of the General Partner owned the following Units at December 31, 2005: Percent of Number of Outstanding Partnership Units Owned Units ----------- ----------- ----------- P-1 31,873 29.5% P-3 71,177 42.0% P-4 34,971 27.7% P-5 30,375 25.6% P-6 21,675 15.2% The Partnerships' sole business is owning Net Profits Interests. Substantially all of the gas production attributable to the Partnerships' Net Profits Interests is being sold regionally on the "spot market." Due to the highly competitive nature of the spot market, prices on the spot market are subject to wide seasonal and regional pricing fluctuations. In addition, such spot market sales are generally short term in nature and are dependent upon obtaining transportation services provided by pipelines. The Partnerships' oil is sold at or near the Partnerships' wells under short-term purchase contracts at prevailing arrangements which are customary in the oil industry. The prices received for the Partnerships' oil and gas are subject to influences such as global consumption and supply trends. F-32 Allocation of Costs and Revenues The combination of the allocation provisions in each Partnerships' limited partnership agreement and NPI Partnerships' partnership agreement (collectively, the "Partnership Agreement") results in allocations of costs and income between the Limited Partners and General Partner as follows: Before Payout(1) After Payout(1) -------------------- -------------------- General Limited General Limited Partner Partners Partner Partners ------- -------- ------- -------- Costs(2) - -------------------------- Sales commissions, payment for organization and offering costs and acquisition fee 1% 99% - - Property Acquisition Costs 1% 99% 1% 99% General and administrative costs and direct administrative costs(3) 5% 95% 15% 85% Income(2) - -------------------------- Temporary investments of Limited Partners' Subscriptions 1% 99% 1% 99% Income from oil and gas production(3) 5% 95% 15% 85% Gain on sale of Net Profits Interests(3) 5% 95% 15% 85% All other income(3) 5% 95% 15% 85% - ---------- (1) Payout occurs when total distributions to Limited Partners equal total original Limited Partner subscriptions. (2) The allocations in the table result generally from the combined effect of the allocation provisions in the Partnership Agreements. For example, direct administrative costs of the NPI Partnership are allocated 95.9596% to the Partnership and 4.0404% to the managing partner. The 95.9596% portion of these costs allocated to the limited partnership, when passed through the limited partnership, is further allocated 99% to the Limited Partners and 1% to the general partner. In this manner the Limited Partners are allocated 95% of such costs and the General Partner is allocated 5% of such costs. F-33 (3) If at payout the total distributions received by the Limited Partners from the commencement of the property investment period have averaged on an annualized basis an amount that is less than 12% of the Limited Partners' subscriptions, the percentage of income, and costs which are shared in the same proportions as income, allocated to the General Partner will increase to only 10% and the Limited Partners will be allocated 90% thereof until such time, if ever, that the distributions to the Limited Partners from the commencement of the property investment period reaches a yearly average equal to at least 12% of the Limited Partners' subscriptions. Thereafter, income, and costs shared in the same proportions as income, will be allocated 15% to the General Partner and 85% to the Limited Partners. After payout, operations and revenues for the Partnerships are allocated using the 10%/90% after payout percentages set forth in Footnote 3 to the table above. The Partnerships achieved payout during the following periods: Partnership Payout Occurred ----------- --------------- P-1 3rd Qtr. 1998 P-3 2nd Qtr. 2000 P-4 4th Qtr. 1999 P-5 3rd Qtr. 2003 P-6 3rd Qtr. 2001 Basis of Presentation These financial statements reflect the combined accounts of each Partnership after the elimination of all inter-partnership transactions and balances. Cash and Cash Equivalents The Partnerships consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents are not insured, which cause the Partnerships to be subject to risk. Credit Risk Accrued oil and gas sales, which are included in the Partnerships' accounts receivable (accounts payable) - Net Profits, are due from a variety of oil and gas purchasers and, therefore, indirectly subject the Partnerships to a concentration of credit risk. Some of these purchasers are discussed in Note 3 - Major Customers. F-34 Net Profits Interests The Partnerships follow the successful efforts method of accounting for their Net Profits Interests. Under the successful efforts method, the Partnerships capitalize all acquisition costs. Such acquisition costs include costs incurred by the Partnerships or the General Partner to acquire a Net Profits Interest, including related title insurance or examination costs, commissions, engineering, legal and accounting fees, and similar costs directly related to the acquisitions plus an allocated portion of the General Partner's property screening costs. The net acquisition cost to the Partnerships of the Net Profits Interests in properties acquired by the General Partner consists of the cost of acquiring the underlying properties, adjusted for the net cash results of operations, including interest incurred to finance the net acquisition, for the period of time the properties are held by the General Partner. Depletion of the cost of Net Profits Interests is computed on the units-of-production method. The Partnerships' calculation of depletion of its Net Profits Interests includes estimated dismantlement and abandonment costs, net of estimated salvage values. The depletion rate, which includes accretion of the asset retirement obligation, per equivalent barrel of oil produced during the years ended December 31, 2005, 2004, and 2003 were as follows: Partnership 2005 2004 2003 ----------- ----- ----- ----- P-1 $1.36 $1.10 $1.21 P-3 1.40 2.28 1.28 P-4 1.70 1.37 1.43 P-5 2.30 1.83 1.36 P-6 3.72 1.47 1.28 The Partnerships evaluate the recoverability of the carrying costs of their Net Profits Interests in proved oil and gas properties at the field level. If the unamortized costs of a Net Profits Interest within a field exceed the expected undiscounted future cash flows from such Net Profits Interest, the cost of the Net Profits Interest is written down to fair value, which is determined by using the discounted future cash flows from the Net Profits Interest. No non-cash charges against earnings (impairment provisions) were recorded by the Partnerships during the three years ended December 31, 2005. The risk that the Partnerships will be required to record impairment provisions in the future increases as oil and gas prices decrease. F-35 Accounts Receivable (Accounts Payable) - Net Profits Revenues from a Net Profits Interest consist of a share of the oil and gas sales of the property, less operating and production expenses. The Partnerships accrue for oil and gas revenues less expenses from its Net Profits Interests. Sales of gas applicable to the Net Profits Interests are recorded as revenue when the gas is metered and title transferred pursuant to the gas sales contracts. During such times as sales of gas exceed a Partnership's pro rata Net Profits Interest in a well, such sales are recorded as revenue unless total sales from the well have exceeded the Partnership's share of estimated total gas reserves attributable to the underlying property, at which time such excess is recorded as a liability. The rates per Mcf used to calculate the liability are based on the average gas price for which the Partnerships are currently settling this liability. This liability is recorded as a reduction of accounts receivable. Also included in accounts receivable (accounts payable) - Net Profits are the estimated asset retirement obligations (see "Asset Retirement Obligation") and the amounts which represent costs deferred or accrued for Net Profits relating to lease operating expenses incurred in connection with the net underproduced or overproduced gas imbalance positions. The rate used in calculating the deferred charge or accrued liability is the average annual production costs per Mcf. The Partnerships have not entered into any hedging or derivative contracts in connection with their production and sale of oil and gas. General and Administrative Overhead The General Partner and its affiliates are reimbursed for actual general and administrative costs incurred and attributable to the conduct of the business affairs and operations of the Partnerships. Use of Estimates in Financial Statements The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Further, accounts receivable (accounts payable) - Net Profits includes accrued liabilities, accrued lease operating expenses, asset retirement obligations, and deferred lease operating expenses related to gas balancing which involve estimates that could materially differ from the actual amounts ultimately F-36 realized or incurred in the near term. Oil and gas reserves (see Note 4) also involve significant estimates which could materially differ from the actual amounts ultimately realized. Income Taxes Income or loss for income tax purposes is includable in the income tax returns of the partners. Accordingly, no recognition has been given to income taxes in these financial statements. Asset Retirement Obligation The Partnerships' wells must be properly plugged and abandoned after their oil and gas reserves are exhausted. FAS No. 143 requires the estimated plugging and abandonment obligations to be recognized in the period in which they are incurred (i.e. when the well is drilled or acquired) if a reasonable estimate of fair value can be made and to be capitalized as part of the carrying amount of the well. Estimated abandonment dates will be revised in the future based on changes to related economic lives, which vary with product prices and production costs. Estimated plugging costs may also be adjusted to reflect changing industry experience. On January 1, 2003, the Partnerships adopted FAS No. 143, "Accounting for Asset Retirement Obligations" and recorded an increase in capitalized cost of oil and gas properties, an increase (decrease) in net income for the cumulative effect of the change in accounting principal, and an asset retirement obligation. During the year ended December 31, 2005, the Partnerships' asset retirement obligations were revised upward due to an increase in both the labor and rig costs associated with plugging wells. Cash flows would not be affected until wells are actually plugged and abandoned. The asset retirement obligation will be adjusted upwards each quarter in order to recognize accretion of the time-related discount factor. For 2005, the P-1, P-3, P-4, P-5, and P-6 Partnerships recognized approximately $17,000, $25,000, $38,000, $30,000, and $95,000, respectively, of an increase in depletion of Net Profits Interests, which was comprised of accretion of the asset retirement obligation and depletion of the increase in Net Profits Interests. The components of the change in asset retirement obligations for the years ended December 31, 2005 and 2004 are as shown below.

TRANSACTIONS WITH RELATED PARTIES The Partnerships reimburse the General Partner for the general and administrative overhead applicable to the Partnerships, based on an allocation of actual costs incurred by the General Partner. When costs incurred benefit other Partnerships and affiliates, the allocation of costs is based on the relationship of the Partnerships' reserves to the total reserves owned by all Partnerships and affiliates. The General Partner believes this allocation method is reasonable. Although the actual costs incurred by the General Partner and its affiliates have fluctuated during the three years presented, the amounts charged to the Partnerships have not fluctuated due to expense limitations imposed by the Partnership Agreement. The following is a summary of payments made to the General Partner or its affiliates by the Partnerships for general and administrative F-39 overhead costs for the years ended December 31, 2005, 2004, and 2003: Partnership 2005 2004 2003 ----------- -------- -------- -------- P-1 $113,760 $113,760 $113,760 P-3 178,560 178,560 178,560 P-4 132,960 132,960 132,960 P-5 124,680 124,680 124,680 P-6 150,564 150,564 150,564 Affiliates of the Partnerships operate certain of the properties in which the Partnerships own a Net Profits Interest and their policy is to bill the owners of the working interests of such properties for all customary charges and cost reimbursements associated with these activities, together with any compressor rentals, consulting, or other services provided. 3. MAJOR CUSTOMERS The following table sets forth purchasers who individually accounted for ten percent or more of combined oil and gas sales attributable to each of the Partnership's Net Profits Interest during the years ended December 31, 2005, 2004, and 2003: Percentage ----------------------------- Partnership Purchaser 2005 2004 2003 - ----------- ------------------------ ----- ----- ----- P-1 Duke Energy Field Services, Inc.

The following table sets forth the development costs related to the working interests which are burdened by the Partnerships' Net Profits Interests during the years ended December 31, 2005, 2004, and 2003. Since these acquisition and development costs were charged against the Net Profits payable to the Partnerships, such costs were indirectly borne by the Partnerships.

Quantities of Proved Oil and Gas Reserves - Unaudited The following tables summarize changes in net quantities of proved reserves attributable to the Partnerships' Net Profits F-43 Interests, all of which are located in the United States of America, for the periods indicated. The proved reserves were estimated by petroleum engineers employed by affiliates of the Partnerships.
