ACCOUNTING POLICIES ------------------- The combined balance sheets as of September 30, 1997, combined statements of operations for the three and nine months ended September 30, 1997 and 1996 and combined statements of cash flows for the nine months ended September 30, 1997 and 1996 have been prepared by Geodyne Resources, Inc., the general partner of the limited partnerships, without audit. Each limited partnership is a general partner in the related Geodyne Energy Income Production Partnership in which Geodyne Resources, Inc. serves as the managing partner. Unless the context indicates otherwise, all references to a "Partnership" or the "Partnerships" are references to the limited partnership and its related production partnership, collectively, and all references to the "General Partner" are references to the general partner of the limited partnerships and the managing partner of the production partnerships, collectively. In the opinion of management the financial statements referred to above include all necessary adjustments, consisting of normal recurring adjustments, to present fairly the combined financial position at September 30, 1997, the combined results of operations for the three and nine months ended September 30, 1997 and 1996 and the combined cash flows for the nine months ended September 30, 1997 and 1996. Information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted. The accompanying interim financial statements should be read in conjunction with the Partnerships' Annual Report on Form 10-K filed for the year ended December 31, 1996. The results of operations for the period ended September 30, 1997 are not necessarily indicative of the results to be expected for the full year. The Limited Partners' net income or loss per unit is based upon each $1,000 initial capital contribution. OIL AND GAS PROPERTIES ---------------------- The Partnerships follow the successful efforts method of accounting for their oil and gas properties. Under the successful efforts method, the Partnerships capitalize all property acquisition costs and development costs incurred in -22- connection with the further development of oil and gas reserves. Property acquisition costs include costs incurred by the Partnerships or the General Partner to acquire producing properties, 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 acquisition cost to the Partnerships of properties acquired by the General Partner is adjusted to reflect the net cash results of operations, including interest incurred to finance the acquisition, for the period of time the properties are held by the General Partner prior to their transfer to the Partnerships. Leasehold impairment is recognized based upon an individual property assessment and exploratory experience. Upon discovery of commercial reserves, leasehold costs are transferred to producing properties. Depletion of the costs of producing oil and gas properties, amortization of related intangible drilling and development costs, and depreciation of tangible lease and well equipment are computed on the unit-of-production method. The Partnerships' depletion, depreciation, and amortization includes estimated dismantlement and abandonment costs, net of estimated salvage value. When complete units of depreciable property are retired or sold, the asset cost and related accumulated depreciation are eliminated with any gain or loss reflected in income. When less than complete units of depreciable property are retired or sold, the difference between asset cost and salvage value is charged to accumulated depreciation. Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment of Long Lived Assets and Assets Held for Disposal", requires successful efforts companies, like the Partnerships, to evaluate the recoverability of the carrying costs of their proved oil and gas properties at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of oil and gas properties. With respect to the Partnerships' oil and gas properties, this evaluation was performed for each field. SFAS No. 121 provides that if the unamortized costs of oil and gas properties for each field exceed the expected undiscounted future cash flows from such properties, the cost of the properties is written down to fair value, which is determined by using the discounted future cash flows from the properties. The Partnerships recorded a non-cash charge against earnings (impairment provision) during the nine months ended September 30, 1997 pursuant to SFAS No. 121 as follows: Partnership Amount ----------- ------------ I-B $ 19,726 I-C 4,679 I-D 61,790 I-E 291,690 I-F 114,631 The risk that the Partnerships will be required to record such impairment provisions in the future increases when oil and gas prices are depressed. -23- 2. TRANSACTIONS WITH RELATED PARTIES --------------------------------- The Partnerships' Partnership Agreements provide for reimbursement to the General Partner for all direct general and administrative expenses and for the general and administrative overhead applicable to the Partnerships based on an allocation of actual costs incurred. During the three months ended September 30, 1997 the following payments were made to the General Partner or its affiliates by the Partnerships: Direct General Administrative Partnership and Administrative Overhead ----------- ------------------ -------------- I-B $2,144 $ 11,313 I-C 1,585 23,382 I-D 1,290 19,986 I-E 7,487 116,220 I-F 2,562 39,780 During the nine months ended September 30, 1997 the following payments were made to the General Partner or its affiliates by the Partnerships: Direct General Administrative Partnership and Administrative Overhead ----------- ------------------ -------------- I-B $15,895 $ 33,939 I-C 11,888 70,146 I-D 10,685 59,958 I-E 57,621 348,660 I-F 20,261 119,340 Affiliates of the Partnerships operate certain of the Partnerships' properties and their policy is to bill the Partnerships for all customary charges and cost reimbursements associated with their activities. The I-C Partnership recorded a receivable from the General Partner at December 31, 1996 in the amount of $14,452 for proceeds due to the I-C Partnership from the sale of oil and gas properties during the fourth quarter of 1996. Subsequent to December 31, 1996 such receivable was collected by the I-C Partnership. The I-C Partnership also recorded a receivable from the General Partner at December 31, 1996 in the amount of $470 due to indirect general and administrative expenses during the fourth quarter of 1996 exceeding the reimbursable indirect limit imposed by the advisory agreement between Samson Investment Company, PaineWebber Incorporated, and Geodyne (the "Advisory Agreement"). Such receivable was collected by the I-C Partnership during the first quarter of 1997. The receivable at September 30, 1997 for the I-B and I-C Partnerships represented proceeds due to such Partnerships for the sale of oil and gas properties during the third quarter of 1997. Subsequent to September 30, 1997 such receivable was collected by the I-B and I-C Partnerships. The I-C Partnership had a payable due to the General Partner of $65,000 at September 30, 1997 included in accounts payable. This -24- payable represents an advance made by the General Partner for working capital needs incurred as a result of a well recompleted in July 1997. The Partnership repaid $30,000 of this liability during October 1997 and expects to repay the remainder during November 1997. No interest has been charged by the General Partner on the accounts payable. -25- ITEM 2: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS USE OF FORWARD-LOOKING STATEMENTS AND ESTIMATES - ----------------------------------------------- This Quarterly 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 Quarterly 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 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 - ------- The Partnerships are engaged in the business of acquiring and operating producing oil and gas properties located in the continental United States. In general, a Partnership acquired producing properties and did not engage in development drilling or enhanced recovery projects, except as an incidental part of the management of the producing properties acquired. Therefore, the economic life of each Partnership, and its related Production Partnership, is limited to the period of time required to fully produce its acquired oil and gas reserves. The net proceeds from the oil and gas operations are distributed to the Limited Partners and the General Partner in accordance with the terms of the Partnerships' Partnership Agreements. LIQUIDITY AND CAPITAL RESOURCES - ------------------------------- The Partnerships began operations and investors were assigned their rights as Limited Partners, having made capital contributions in the amounts and on the dates set forth below: -26- Limited Date of Partner Capital Partnership Activation Contributions ----------- ------------------ --------------- I-B July 12, 1985 $11,957,700 I-C December 20, 1985 8,884,900 I-D March 4, 1986 7,194,700 I-E September 10, 1986 41,839,400 I-F December 16, 1986 14,320,900 In general, the amount of funds available for acquisition of producing properties was equal to the capital contributions of the Limited Partners, less 15% for sales commissions and organization and management fees. All of the Partnerships have fully invested their capital contributions. Net proceeds from the operations less necessary operating capital are distributed to the Limited Partners on a quarterly basis. Revenues and net proceeds of a Partnership are largely dependent upon the volumes of oil and gas sold and the prices received for such oil and gas. The I-C Partnership experienced negative cash flow during the three months ended September 30, 1997 due to capital expenditures of approximately $100,000 for the successful recompletion of one well. Management believes the negative cash flow for the I-C Partnership during the third quarter of 1997 was an isolated event and does not anticipate similar negative cash flows in the future. While the General Partner cannot predict future pricing trends, it believes the working capital available as of September 30, 1997 and the net revenue generated from future operations will provide sufficient working capital to meet current and future obligations of the Partnerships. RESULTS OF OPERATIONS - --------------------- GENERAL DISCUSSION The following general discussion should be read in conjunction with the analysis of results of operations provided below. The most important variable affecting the Partnerships' revenues is the prices received for the sale of oil and gas. Predicting future prices is very difficult. Substantially all of the Partnerships' gas reserves are being sold in the "spot market". Prices on the spot market are subject to wide seasonal and regional pricing fluctuations due to the highly competitive nature of the spot market. In addition, such spot market sales are generally short-term in nature and are dependent upon the obtaining of transportation services provided by pipelines. Management is unable to predict whether future oil and gas prices will (i) stabilize, (ii) increase, or (iii) decrease. I-B PARTNERSHIP THREE MONTHS ENDED SEPTEMBER 30, 1997 AS COMPARED TO THE THREE MONTHS ENDED SEPTEMBER 30, 1996. Three Months Ended September 30, -------------------------------- 1997 1996 ------- ------- Oil and gas sales $45,296 $83,427 -27- Oil and gas production expenses $28,931 $34,592 Barrels produced 515 529 Mcf produced 16,820 34,787 Average price/Bbl $ 18.51 $ 23.68 Average price/Mcf $ 2.13 $ 2.04 As shown in the table above, total oil and gas sales decreased $38,131 (45.7%) for the three months ended September 30, 1997 as compared to the three months ended September 30, 1996. Of this decrease, approximately $37,000 was related to a decrease in volumes of gas sold. Volumes of oil and gas sold decreased 14 barrels and 17,967 Mcf, respectively for the three months ended September 30, 1997 as compared to the three months ended September 30, 1996. The decrease in volumes of gas sold resulted primarily from positive prior period volume adjustments made by the purchasers on three wells during the three months ended September 30, 1996. Average oil prices decreased to $18.51 per barrel for the three months ended September 30, 1997 from $23.68 per barrel for the three months ended September 30, 1996. Average gas prices increased to $2.13 per Mcf for the three months ended September 30, 1997 from $2.04 per Mcf for the three months ended September 30, 1996. Oil and gas production expenses (including lease operating expenses and production taxes) decreased $5,661 (16.4%) for the three months ended September 30, 1997 as compared to the three months ended September 30, 1996. This decrease resulted primarily from (i) the decrease in volumes of gas sold for the three months ended September 30, 1997 as compared to the three months ended September 30, 1996 and (ii) a decrease in production taxes associated with the decrease in oil and gas sales discussed above, which decrease was partially offset by recompletion expenses incurred on one well during the three months ended September 30, 1997 in order to improve the recovery of reserves. As a percentage of oil and gas sales, these expenses increased to 63.9% for the three months ended September 30, 1997 from 41.5% for the three months ended September 30, 1996. This percentage increase was primarily due to the recompletion expenses discussed above. Depreciation, depletion, and amortization of oil and gas properties decreased $12,654 (62.9%) for the three months ended September 30, 1997 as compared to the three months ended September 30, 1996. This decrease resulted primarily from the decrease in volumes of gas sold during the three months ended September 30, 1997 as compared to the three months ended September 30, 1996. As a percentage of oil and gas sales, this expense decreased to 16.5% for the three months ended September 30, 1997 from 24.1% for the three months ended September 30, 1996. This percentage decrease was primarily due to the dollar decrease in depreciation, depletion, and amortization discussed above and the increase in the average price of gas sold during the three months ended September 30, 1997 as compared to the three months ended September 30, 1996. General and administrative expenses remained relatively constant for the three months ended September 30, 1997 as compared to the three months ended September 30, 1996. As a percentage of oil and gas sales, these expenses increased to 29.7% for the three months ended September 30, 1997 from 16.9% for the three months -28- ended September 30, 1996. This percentage increase was primarily due to the decrease in oil and gas sales discussed above. NINE MONTHS ENDED SEPTEMBER 30, 1997 AS COMPARED TO THE NINE MONTHS ENDED SEPTEMBER 30, 1996. Nine Months Ended September 30, ------------------------------- 1997 1996 -------- -------- Oil and gas sales $236,834 $223,828 Oil and gas production expenses $ 90,320 $128,130 Barrels produced 1,628 1,842 Mcf produced 85,508 92,509 Average price/Bbl $ 19.54 $ 20.42 Average price/Mcf $ 2.40 $ 2.01 As shown in the table above, total oil and gas sales increased $13,006 (5.8%) for the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. Of this increase, approximately $33,000 was related to an increase in the average price of gas sold, which increase was partially offset by decreases of approximately $4,000 and $14,000, respectively, related to decreases in volumes of oil and gas sold. Volumes of oil and gas sold decreased 214 barrels and 7,001 Mcf, respectively, for the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. Average oil prices decreased to $19.54 per barrel for the nine months ended September 30, 1997 from $20.42 per barrel for the nine months ended September 30, 1996. Average gas prices increased to $2.40 per Mcf for the nine months ended September 30, 1997 from $2.01 per Mcf for the nine months ended September 30, 1996. Oil and gas production expenses (including lease operating expenses and production taxes) decreased $37,810 (29.5%) for the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. This decrease resulted primarily from (i) the sale of one well during the nine months ended September 30, 1996, (ii) workover expenses incurred on two wells during the nine months ended September 30, 1996 in order to improve the recovery of reserves and (iii) decreases in volumes of oil and gas sold for the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. As a percentage of oil and gas sales, these expenses decreased to 38.1% for the nine months ended September 30, 1997 from 57.2% for the nine months ended September 30, 1996. This percentage decrease was primarily due to the dollar decrease in oil and gas production expenses discussed above and the increase in the average price of gas sold during the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. Depreciation, depletion, and amortization of oil and gas properties decreased $19,159 (34.9%) for the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. This decrease resulted primarily from an upward revision in the estimate of remaining gas reserves at December 31, 1996. As a percentage of oil and gas sales, this expense decreased to 15.1% for the nine months ended September 30, 1997 from 24.5% for the nine months ended September 30, 1996. This percentage decrease was primarily due to the increase in the -29- average price of gas sold during the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. The I-B Partnership recognized a non-cash charge against earnings of $19,726 for the nine months ended September 30, 1997. This impairment provision was necessary due to the unamortized costs of oil and gas properties exceeding the expected undiscounted future net revenues from such oil and gas properties, in accordance with the I-B Partnership s adoption of SFAS No. 121. Of this amount, $17,233 was related to the decline in oil and gas prices used to determine the recoverability of oil and gas reserves at March 31, 1997 and $2,493 was related to impairment of unproved properties. No similar charge was necessary during the nine months ended September 30, 1996. General and administrative expenses remained relatively constant for the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. As a percentage of oil and gas sales, these expenses decreased to 21.0% for the nine months ended September 30, 1997 from 21.6% for the nine months ended September 30, 1996. This percentage decrease was primarily due to the increase in oil and gas sales discussed above. The Limited Partners have received cash distributions through September 30, 1997 totaling $6,522,527 or 54.55% of Limited Partners' capital contributions. I-C PARTNERSHIP THREE MONTHS ENDED SEPTEMBER 30, 1997 AS COMPARED TO THE THREE MONTHS ENDED SEPTEMBER 30, 1996. Three Months Ended September 30, -------------------------------- 1997 1996 -------- -------- Oil and gas sales $203,427 $262,585 Oil and gas production expenses $ 97,752 $ 87,432 Barrels produced 5,660 6,267 Mcf produced 38,365 45,761 Average price/Bbl $ 17.12 $ 21.00 Average price/Mcf $ 2.78 $ 2.86 As shown in the table above, total oil and gas sales decreased $59,158 (22.5%) for the three months ended September 30, 1997 as compared to the three months ended September 30, 1996. Of this decrease, approximately $13,000 and $21,000, respectively, were related to decreases in volumes of oil and gas sold and approximately $22,000 was related to the decrease in the average price of oil sold. Volumes of oil and gas sold decreased 607 barrels and 7,396 Mcf, respectively, for the three months ended September 30, 1997 as compared to the three months ended September 30, 1996. The decrease in volumes of gas sold resulted primarily from the shutting-in of one well due to a workover during the three months ended September 30, 1997 in order to -30- improve the recovery of reserves. Average oil and gas prices decreased to $17.12 per barrel and $2.78 per Mcf, respectively, for the three months ended September 30, 1997 from $21.00 per barrel and $2.86 per Mcf, respectively, for the three months ended September 30, 1996. Oil and gas production expenses (including lease operating expenses and production taxes) increased $10,320 (11.8%) for the three months ended September 30, 1997 as compared to the three months ended September 30, 1996. This increase resulted primarily from workover expenses incurred on one well during the three months ended September 30, 1997 in order to improve the recovery of reserves, which increase was partially offset by decreases in volumes of oil and gas sold during the three months ended September 30, 1997 as compared to the three months ended September 30, 1996. As a percentage of oil and gas sales, these expenses increased to 48.1% for the three months ended September 30, 1997 from 33.3% for the three months ended September 30, 1996. This percentage increase was primarily due to the workover expenses discussed above and the decrease in the average prices of oil and gas sold during the three months ended September 30, 1997 as compared to the three months ended September 30, 1996. Depreciation, depletion, and amortization of oil and gas properties decreased $20,488 (68.6%) for the three months ended September 30, 1997 as compared to the three months ended September 30, 1996.

Nine months Ended September 30, ------------------------------- 1997 1996 ---------- ---------- Oil and gas sales $1,579,881 $1,439,794 Oil and gas production expenses $ 574,012 $ 464,818 Barrels produced 29,318 27,823 Mcf produced 429,479 457,558 Average price/Bbl $ 19.40 $ 19.41 Average price/Mcf $ 2.35 $ 1.97 As shown in the table above, total oil and gas sales increased $140,087 (9.7%) for the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. Of this -40- increase, approximately $163,000 was related to an increase in the average price of gas sold and approximately $29,000 was related to an increase in volumes of oil and gas sold, which increase was partially offset by a decrease of approximately $55,000 related to a decrease in volumes of gas sold. Volumes of oil sold increased 1,495 barrels, while volumes of gas sold decreased 28,079 Mcf for the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. Average oil prices decreased to $19.40 per barrel for the nine months ended September 30, 1997 from $19.41 per barrel for the nine months ended September 30, 1996. Average gas prices increased to $2.35 per Mcf for the nine months ended September 30, 1997 from $1.97 per Mcf for the nine months ended September 30, 1996. Oil and gas production expenses (including lease operating expenses and production taxes) increased $109,194 (23.5%) for the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. This increase resulted primarily from (i) workover expenses incurred on three wells during the nine months ended September 30, 1997 in order to improve the recovery of reserves and (ii) recompletion expenses incurred on one well during the nine months ended September 30, 1997 in order to improve the recovery of reserves. As a percentage of oil and gas sales, these expenses increased to 36.3% for the nine months ended September 30, 1997 from 32.3% for the nine months ended September 30, 1996. This percentage increase was primarily due to the dollar increase in oil and gas production expenses discussed above. Depreciation, depletion, and amortization of oil and gas properties decreased $50,680 (21.3%) for the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. This decrease resulted primarily from (i) upward revisions in the estimates of remaining oil and gas reserves at December 31, 1996 and (ii) decreases in volumes of oil and gas sold during the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. As a percentage of oil and gas sales, this expense decreased to 11.9% for the nine months ended September 30, 1997 from 16.6% for the nine months ended September 30, 1996. This percentage decrease was primarily due to the dollar decrease in depreciation, depletion, and amortization discussed above and the increase in the average price of gas sold during the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. The I-F Partnership recognized a non-cash charge against earnings of $114,631 for the nine months ended September 30, 1997. This impairment provision was necessary due to the unamortized costs of oil and gas properties exceeding the expected undiscounted future net revenues from such oil and gas properties, in accordance with the I-F Partnership s adoption of SFAS No. 121. Of this amount, $20,908 was related to the decline in oil and gas prices used to determine the recoverability of oil and gas reserves at March 31, 1997 and $93,723 was related to impairment -41- of unproved properties. No similar charge was necessary during the nine months ended September 30, 1996. General and administrative expenses remained relatively constant for the nine months ended September 30, 1997 as compared to the nine months ended September 30, 1996. As a percentage of oil and gas sales, these expenses decreased to 8.8% for the nine months ended September 30, 1997 from 9.6% for the nine months ended September 30, 1996. This percentage decrease was primarily due to the increase in oil and gas sales discussed above. The Limited Partners have received cash distributions through September 30, 1997 totaling $16,554,664 or 115.60% of Limited Partners' capital contributions. -42- PART II: OTHER INFORMATION ITEM 6.
