ITEM 1. BUSINESS
ITEM 1. BUSINESS
General
Apache Offshore Investment Partnership, a Delaware general partnership (the Investment Partnership), was formed on October 31, 1983, consisting of Apache Corporation, a Delaware corporation (Apache or Managing Partner), as Managing Partner and public investors (the Investing Partners). The Investment Partnership invested its entire capital in Apache Offshore Petroleum Limited Partnership, a Delaware limited partnership (the Operating Partnership), of which Apache is the sole general partner and the Investment Partnership is the sole limited partner. The primary business of the Investment Partnership is to serve as the sole limited partner of the Operating Partnership. The primary business of the Operating Partnership is to conduct oil and gas development and production operations. The Operating Partnership conducts the operations of the Investment Partnership.
On March 1, 2021, Apache consummated a holding company reorganization (the Holding Company Reorganization), pursuant to which, Apache became a wholly-owned subsidiary of APA Corporation (APA), APA became the successor issuer to Apache pursuant to Rule 12g-3(a) under the Securities Exchange Act of 1934, as amended (the Exchange Act), and APA replaced Apache as the public company trading on the Nasdaq Global Select Market under the ticker symbol “APA.” Following consummation of the Holding Company Reorganization, the Partnership’s executive management and governance functions are performed by the executive officers and directors of APA, respectively.
The Investment Partnership does not maintain its own website. However, copies of this Form 10-K and the Investment Partnership’s periodic filings with the Securities and Exchange Commission (SEC) can be found on APA’s website at investor.apacorp.com/apache-offshore-investment-partnership. The Investment Partnership will also provide paper copies of these filings, free of charge, to anyone so requesting. Included in the Investment Partnership’s Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q are the certifications of the Managing Partners’ principal executive officer and principal financial officer that are required by applicable laws and regulations. Any requests to the Partnership for copies of documents filed with the SEC should be made by mail to Apache Offshore Investment Partnership, 2000 Post Oak Blvd., Houston, Texas 77056, Attention: Investor Relations, or by telephone at 1-281-302-2286. Reports filed with the SEC are also made available on its website at www.sec.gov. Information on APA’s website or any other website is not incorporated by reference into, and does not constitute a part of this Form 10-K.
The Investing Partners purchased Units of Partnership Interests (Units) in the Investment Partnership at $150,000 per Unit, with five percent down and the balance in payments as called by the Investment Partnership. As of December 31, 2022, a total of $85,000 had been called for each Unit. In 1989, the Investment Partnership determined that the full $150,000 per Unit was not needed, fixed the total calls at $85,000 per Unit, and released the Investing Partners from liability for future calls. The Investment Partnership invested, and will continue to invest, its entire capital in the Operating Partnership. As used hereafter, the term “Partnership” refers to either the Investment Partnership or the Operating Partnership, as the case may be.
The Partnership’s business is participation in oil and gas development and production activities on federal lease tracts in the Gulf of Mexico, offshore Louisiana. Except for an additional interest acquired in Matagorda Island Block 681 and 682 in 1992, the Partnership acquired its oil and gas interests through the purchase of 85 percent of the working interests held by Apache as a participant in a venture (the Venture) with Shell Oil Company (Shell) and certain other companies. The Venture acquired substantially all of its oil and gas properties through bidding for leases offered by the federal government and relied on Shell’s knowledge and expertise in determining bidding strategies and development of the properties. The remaining 15 percent interest was purchased by an affiliated partnership or retained by Apache.
Since inception, the Partnership has acquired an interest in 49 prospects. As of December 31, 2022, 48 of those prospects have been surrendered or sold. As of December 31, 2022, the Partnership had 13 productive wells on its remaining developed field, South Timbalier 295, offshore Louisiana, with a 7.08 percent working interest.
Notice of Withdrawal
Apache, as the Managing Partner of the Investment Partnership, gave notice on March 22, 2019 of its intention to withdraw as Managing Partner of the Investment Partnership. The notice described the withdrawal process and certain notice periods required by that process. No party assumed the role of Managing Partner within the 120-day notice period specified by the notice of intention to withdraw. Consequently, Apache will oversee the process of winding up and liquidating the business and affairs of the Investment Partnership. Apache has not made a decision as to when it will complete the process to withdraw as Managing Partner.
Apache will continue to manage the Partnership’s business activities during the winding up process. Apache uses a portion of its staff and facilities for this purpose and is reimbursed for actual costs paid on behalf of the Partnership, as well as for general, administrative and overhead costs properly allocated to the Partnership.
2022 Results
The Partnership reported net income for 2022 of approximately $575 thousand, or approximately $392 per Investing Partner Unit. This represents an increase in net income of approximately $1.2 million compared to the $657 thousand net loss reported in 2021.
The increase in net income compared to the prior year was the result of higher realized commodity prices and higher production during 2022 compared to 2021. In late June 2021, the operator shut in wells at South Timbalier 295 in order to perform certain repairs to various piping and related equipment. As a result of the wells being shut in at South Timbalier 295, the Partnership had de minimis production and associated revenues during the second half of 2021, as South Timbalier 295 is the only remaining operating field of the Partnership. The Partnership operated at a loss during 2021 as a result of the reduced production levels and the increased repair and maintenance costs incurred over the second half of 2021. The shut-in wells returned to production at the end of December of 2021 after repairs were substantially completed, and production levels for the Partnership returned to normalized levels during 2022.
Oil production averaged 44 barrels of oil per day in 2022, up 120 percent from 2021. Natural gas production averaged 88 Mcf per day in 2022, up 87 percent from 2021. The Partnership’s average realized crude oil prices during 2022 increased 67 percent from the prior year to $92.95 per barrel, while average gas prices increased 131 percent from the prior year to $7.05 per Mcf. The increase in realized prices compared to the prior year was primarily driven by effects of global inflation and the conflict in Ukraine on global commodity prices during 2022.
During 2022, the Partnership did not have any cash outlay for capital expenditures. The Partnership did not participate in any new drilling projects during the year. The Partnership anticipates that 2023 capital expenditures will remain at minimal levels for recompletions at South Timbalier 295.
Approximately $27 thousand of cash outlays were spent during 2022 on abandonment and decommissioning activities primarily at South Timbalier 295. The Partnership anticipates spending $408 thousand of short-term abandonment and decommissioning activity primarily at North Padre Island 969/976 in 2023. Such estimates may change based on realized oil and gas prices, rates charged by contractors, or changes by the operator to its development or abandonment plans.
The Partnership had estimated proved oil and gas reserves of 504,721 barrels of oil equivalent, determined by using the ratio of one barrel of oil or NGLs to six Mcf of gas, at December 31, 2022.
For a more in-depth discussion of the Partnership’s 2022 results and its capital resources and liquidity, please see Part II, Item 7 - “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Form 10-K.
Marketing
Apache, as Managing Partner of the Partnership, markets the Partnership’s share of oil production from South Timbalier 295, which is the Partnership’s primary source of revenue. Apache primarily markets to major oil companies, marketing and transportation companies, and refiners at current index prices, adjusted for quality, transportation, and market-reflective differentials.
The third-party operator of South Timbalier 295 markets all other production of the Partnership. Through the operator, the Partnership’s natural gas is sold primarily to Local Distribution Companies (LDCs), utilities, end-users, and integrated major oil companies. Most of the Partnership’s natural gas is sold on a monthly basis at either monthly or daily market prices. The Partnership believes that the sales prices it receives for oil and natural gas sales are market prices.
For a more in-depth discussion of the Partnership’s significant customers, see Note 5-Major Customer and Related Parties Information in the Notes to the Consolidated Financial Statements set forth in Part II, Item 8 - “Financial Statements and Supplementary Data” of this Form 10-K. Because the Partnership’s oil and gas products are commodities and the prices and terms of its sales reflect those of the market, the Partnership does not believe that the loss of any customer would have a material adverse effect on the Partnership’s business or results of operations.
Environmental Compliance
As an owner or lessee and prior operator of oil and gas properties and facilities, the Partnership is subject to numerous federal, state, and local laws and regulations relating to discharge of materials into, and protection of, the environment. These laws and regulations may, among other things, impose liability on the lessee under an oil and gas lease for the cost of pollution clean-up resulting from operations, subject the lessee to liability for pollution damages and require suspension or cessation of operations in affected areas. Although environmental requirements have a substantial impact upon the energy industry, as a whole, the Partnership does not believe that these requirements affect it differently, to any material degree, than other companies in its industry.
The Partnership has made and will continue to make expenditures in its efforts to comply with these requirements, which it believes are necessary business costs in the oil and gas industry. The Managing Partner has established policies for continuing compliance with environmental laws and regulations, including regulations applicable to the Partnership’s operations. The costs incurred under these policies and procedures are inextricably connected to normal operating expenses such that the Partnership is unable to separate expenses related to environmental matters; however, the Partnership does not believe expenses related to training and compliance with regulations and laws that have been adopted or enacted to regulate the discharge of materials into the environment will have a material impact on its capital expenditures or earnings.

Estimated Proved Reserves and Future Net Cash Flows
Proved oil and gas reserves are those quantities of natural gas, crude oil, condensate, and NGLs that by analysis of geoscience and engineering data can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations. Reserve estimates are considered proved if they are economically producible and are supported by either actual production or conclusive formation tests. Estimated reserves that can be produced economically through application of improved recovery techniques are included in the “proved” classification when successful testing by a pilot project or the operation of an active, improved recovery program using reliable technology establishes the reasonable certainty for the engineering analysis on which the project or program is based. Economically producible means a resource which generates revenue that exceeds, or is reasonably expected to exceed, the costs of the operation. Reasonable certainty means a high degree of confidence that the quantities will be recovered. Reliable technology is a grouping of one or more technologies (including computational methods) that have been field tested and have been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation. Estimated proved developed oil and gas reserves can be expected to be recovered through existing wells with existing equipment and operating methods.
As of December 31, 2022, the Partnership had total estimated proved reserves of 358,017 barrels of crude oil and condensate, 23,371 barrels of NGLs and 740 MMcf of natural gas. Combined, these total estimated proved reserves are equivalent to 504,721 barrels of oil. The Partnership has elected not to disclose probable and possible reserves or reserve estimates based upon futures or other prices in this filing.
The following table shows proved developed and undeveloped oil, NGLs, and gas reserves as of December 31, 2022, based on commodity average prices in effect on the first day of each month in 2022, held flat for the life of the production, except where future oil and gas sales are covered by physical contract terms.

The Partnership’s estimates of proved reserves and proved developed reserves at December 31, 2022, 2021, and 2020, changes in estimated proved reserves during the last three years, and estimates of future net cash flows and discounted future net cash flows from proved reserves are contained in Note 10-Supplemental Oil and Gas Disclosures (Unaudited) in the Notes to the Consolidated Financial Statements set forth in Part II, Item 8 - “Financial Statements and Supplementary Data” of this Form 10-K. Estimated future net cash flows were calculated using a discount rate of 10 percent per annum, end of period costs, and average commodity prices in effect on the first day of each of the previous 12 months, held flat for the life of the production, except where future oil and gas sales are covered by physical contract terms.
The volumes of reserves are estimates which, by their nature, are subject to revision. The estimates are made using available geological and reservoir data, as well as production performance data. These estimates are reviewed annually and revised, either upward or downward, as warranted by additional performance data.
The Partnership’s estimate of proved oil and gas reserves is prepared by Ryder Scott Company, L.P. Petroleum Consultants (Ryder Scott) utilizing oil and gas price data and cost estimates provided by Apache as Managing Partner. Ryder Scott is an independent petroleum engineering consulting firm that has been providing petroleum consulting services throughout the world for over eighty years. A copy of Ryder Scott’s report on the Shell Offshore Venture, which presents the Partnership’s ownership interest at December 31, 2022, is filed as an exhibit to this Form 10-K.
The primary technical person responsible for overseeing the preparation of the Partnership’s reserve estimates is Mr. Ali A. Porbandarwala, a Managing Senior Vice President with Ryder Scott. Mr. Porbandarwala has more than fourteen years of experience in the estimation and evaluation of petroleum reserves and is a registered Professional Engineer in the State of Texas. He is also a member of the Society of Petroleum Engineers and the Society of Petroleum Evaluation Engineers.
At least annually, each property is reviewed in detail by Apache’s centralized and operating region engineers to ensure forecasts of operating expenses, netback prices, production trends and development timing are reasonable. Apache’s engineers furnish this information and estimates of dismantlement and abandonment cost to Ryder Scott for their consideration in preparing the Partnership’s reserve reports. The internal property reviews and collection of data provided to Ryder Scott is overseen by Apache’s Executive Vice President over reservoir engineering.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS
ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Overview
The Partnership’s business is participation in oil and gas development and production activities on federal lease tracts in the Gulf of Mexico, offshore Louisiana. The Partnership is a very minor participant in the oil and gas industry and faces strong competition in all aspects of its business. With a relatively small amount of capital invested in the Partnership and management’s decision to avoid incurring debt, the Partnership has not engaged in acquisition or exploration activities in recent years. The Partnership has not carried any debt since January 1997. The limited amount of capital and the Partnership’s modest reserve base have contributed to the Partnership focusing primarily on production activities on remaining leases and dismantlement and abandonment activities on surrendered leases.
The following discussion should be read together with the Consolidated Financial Statements and the Notes to Consolidated Financial Statements set forth in Part II, Item 8 - “Financial Statements and Supplementary Data” of this Form 10-K. This section of this Form 10-K generally discusses 2022 and 2021 items and year-to-year comparisons between 2022 and 2021. Discussions of 2020 items and year-to-year comparisons between 2021 and 2020 that are not included in this Form 10-K are incorporated by reference to Part II, Item 7 - “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on February 22, 2022.
The Partnership derives its revenue primarily from the production and sale of crude oil, natural gas and NGLs. With only modest levels of production from current wells, the Partnership sells its production at market prices and has not used derivative financial instruments or otherwise engaged in hedging activities. Given the small number of producing wells owned by the Partnership and exposure to inclement weather and pipeline interruptions in the Gulf of Mexico, the Partnership’s production is subject to higher volatility than those companies with a larger or more diversified property portfolio. Extended downtime of the Partnership’s producing properties could materially impact any anticipated revenues, earnings, and cash flow.
The Partnership participates in workover and recompletion activities as recommended by the operator of the properties in which the Partnership owns an interest. During 2022, the Partnership had no cash outlay for oil and gas property additions and did not participate in any new drilling projects or completions. The Partnership’s primary cash outlay for 2022 was for operating expenses and administrative overhead. Platform removal and decommissioning activity at North Padre Island 969/976 was deferred to 2023.
Because of expected declines in production levels, volatility in commodity prices in recent years, and the need to reserve cash for future asset retirement obligations, the Partnership did not make any distributions to the Investing Partners during 2022. The Partnership will continue to review available cash balances, scheduled plugging and abandonment activity, oil and gas prices realized by the Partnership for the sale of its production, and the anticipated level of recompletion and repair activity to determine whether there are sufficient funds to make a distribution to Investing Partners in 2023.
Results of Operations
This section includes a discussion of the Partnership’s results of operations and items contributing to changes in revenues and expenses during 2022 and 2021.
Net Income and Revenue
The Partnership reported net income of approximately $575 thousand for 2022. This represents an increase of approximately $1.2 million from the $657 thousand of net loss reported for 2021. On a per Investing Partner Unit basis, the Partnership reported net income of $392 per Unit in 2022 compared to a net loss of $543 per Unit in 2021. Total revenues in 2022 of approximately $1.8 million increased approximately $1.3 million, or 285 percent, from 2021.
In late June 2021, the operator shut in wells at South Timbalier 295 in order to perform certain repairs to various piping and related equipment. As a result of the wells being shut in at South Timbalier 295, the Partnership had de minimis production and associated revenues during the second half of 2021, as South Timbalier 295 is the only remaining operating field of the Partnership. The Partnership operated at a loss during 2021 as a result of the reduced production levels and the increased repair and maintenance costs incurred over the second half of 2021. The shut-in wells returned to production at the end of December of 2021, after repairs were substantially completed, and production levels for the Partnership returned to normalized levels during 2022.
During 2022, commodity prices increased significantly compared to the prior year, primarily driven by effects of global inflation and the conflict in Ukraine. The Partnership’s average realized oil prices increased 67 percent from 2021, while natural gas prices increased 131 percent from the prior year. Comparative changes in net income and revenues were driven by production levels at South Timbalier 295 and higher realized commodity prices during 2022.
The Partnership’s oil, gas, and NGL production volume and price information is summarized in the following table (gas volumes are presented in thousand cubic feet (Mcf) per day):
For the Year Ended December 31,
2022 Increase
(Decrease) 2021 Increase
(Decrease) 2020
Gas volume - Mcf per day 88 87 % 47 (40) % 78
Average gas price - per Mcf $ 7.05 131 % $ 3.05 22 % $ 2.50
Oil volume - barrels per day 44 120 % 20 (49) % 39
Average oil price - per barrel $ 92.95 67 % $ 55.57 49 % $ 37.26
NGL volume - barrels per day 3 50 % 2 (33) % 3
Average NGL price - per barrel $ 34.02 63 % $ 20.83 65 % $ 12.59
Declines in oil and gas production can generally be expected in future years as a result of normal depletion. Given the small number of producing wells owned by the Partnership and the faster decline in production from offshore wells compared to onshore wells, the Partnership’s future production will be subject to more volatility than those companies with greater reserves and longer-lived properties. It is not anticipated that the Partnership will acquire any additional exploratory leases or that significant drilling will take place on leases in which the Partnership currently holds interests.
Oil and Gas Sales
The Partnership’s crude oil sales in 2022 totaled approximately $1.5 million, up 271 percent from 2021 as a result of higher production and higher realized prices. Oil production was up approximately 120 percent from the prior year, primarily the result of shut-in wells returning to production at South Timbalier 295 after repairs were completed at the end of 2021. The Partnership’s average realized oil price in 2022 was 67 percent higher than in 2021, increasing to $92.95 per barrel in 2022.
Natural gas sales in 2022 increased 335 percent from the prior year, totaling approximately $227 thousand, the result of the return of production at South Timbalier 295 and higher realized natural gas prices during 2022.
The Partnership sold an average of 3 barrels per day of NGLs in 2022, up slightly from 2 barrels per day in 2021. Total NGL sales of approximately $41 thousand was an increase of 154 percent from the prior year, a result of production returning to normal levels and higher realized NGL prices during 2022.
Operating Expenses
The Partnership’s depreciation, depletion and amortization (DD&A), expressed as a percentage of oil and gas sales, decreased to approximately 22 percent in 2022 from approximately 35 percent in 2021, a result of significantly higher realized oil and gas prices driving up revenues during 2022. The dollar amount of recurring DD&A expense for 2022 increased 140 percent from the comparable period a year ago as a result of higher crude oil and natural gas production. During 2022 and 2021, the Partnership recognized asset retirement obligation (ARO) accretion expense of approximately $82 thousand and $53 thousand, respectively. The increase was primarily driven by higher estimates for plugging and abandonment costs at South Timbalier 295. Abandonment spending was minimal during 2022 as abandonment activities at Ship Shoal 258/259 were substantially completed during 2021.
Lease operating expenses (LOE) for 2022 decreased 29 percent from the same period a year ago to approximately $434 thousand in 2022. The decrease was primarily a result of higher costs incurred during 2021 for repair and maintenance work related to equipment repairs and damage resulting from Hurricane Ida. Gathering and transportation costs for the delivery of oil and gas totaled approximately $23 thousand in 2022, an increase of 233 percent from the same period a year ago, primarily the result of production returning to normalized levels. Administrative expenses for 2022 totaled $298 thousand compared to $290 thousand during the prior year.
Under the full cost method of accounting, the Partnership is required to review the carrying value of its proved oil and gas properties each quarter. Under these rules, capitalized costs of oil and gas properties, net of accumulated DD&A, may not exceed the present value of estimated future net cash flows from proved oil and gas reserves discounted at 10 percent per annum. Estimated future net cash flows are calculated using end-of-period costs and an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12 months, held flat for the life of the production, except where prices are defined by contractual arrangements. The Partnership did not recognize any write-downs for the carrying value of its oil and gas properties during 2022 or 2021. Write-downs, if any, are reflected as additional DD&A expense. If commodity prices experience sustained declines over a 12-month period, the Partnership may be required to recognize non-cash write-downs of the carrying value of its oil and gas properties in future periods.
Capital Resources and Liquidity
The Partnership’s primary capital resource is net cash provided by operating activities. During 2022, cash from operating activities resulted in cash inflows of approximately $619 thousand, compared to cash outflows of $415 thousand during 2021. Cash flows from operating activities reflect the impact of higher oil and gas revenues, offset by accrued repair and maintenance costs paid in 2022 and other changes to operating assets and liabilities.
At December 31, 2022, the Partnership had approximately $4.7 million in cash and cash equivalents, up 12 percent from the end of 2021, primarily the result of higher commodity prices and production. The Partnership’s goal is to maintain cash and cash equivalents at least sufficient to cover the undiscounted value of its future asset retirement obligation liability. The Partnership also plans to reserve funds for anticipated repairs on aging infrastructure and for future recompletion operations.
The Partnership’s future financial condition, results of operations and cash from operating activities will largely depend upon prices received for its oil and natural gas production. A substantial portion of the Partnership’s production is sold under market-sensitive contracts. Prices for oil and natural gas are subject to fluctuations in response to changes in supply, market uncertainty and a variety of factors beyond the Partnership’s control. These factors include worldwide political and economic conditions, the foreign and domestic supply of oil and natural gas, the price of foreign imports, the level of consumer demand, weather and the price and availability of alternative fuels.
The Partnership’s oil and gas reserves and production will also significantly impact future results of operations and cash from operating activities. The Partnership’s production is subject to fluctuations in response to remaining quantities of oil and gas reserves, weather, pipeline capacity, consumer demand, mechanical well performance, workovers, and recompletions. Declines in oil and gas production can be expected in future years as a result of normal depletion and the non-participation in acquisition or exploration activities by the Partnership.
Based on production estimates from independent engineers and existing cash balances reserved for platform dismantlement and abandonment activities, current market conditions resulting from the recent rise in inflation and interest rates, and geopolitical events, including the Russian war in Ukraine, are not expected to materially impact the Partnership’s liquidity. The Partnership forecasts it will be able to meet its liquidity needs for routine operations in 2023 and 2024, although volatility in oil and gas prices and slowing consumer demand resulting from current market conditions could affect revenues and could require the Partnership to further reduce its cash and cash equivalents.
Approximately 91 percent of the Partnership’s total proved reserves on a barrels of oil equivalent basis are classified as proved not producing. These reserves relate to zones that are either behind pipe, or that have been completed but not yet produced or zones that have been produced in the past, but are not now producing due to mechanical reasons. These reserves may be regarded as less certain than producing reserves because they are frequently based on volumetric calculations rather than performance data. Future production associated with behind pipe reserves is scheduled to follow depletion of the currently producing zones in the same wellbores. It should be noted that additional capital will have to be spent to access these reserves. The Partnership’s liquidity may be negatively impacted if the actual quantities of reserves that are ultimately produced are materially different from current estimates. Also, if prices decline significantly from current levels, the Partnership may not be able to fund the necessary capital investment, or development of the remaining reserves may not be economical for the Partnership.
In the event that future short-term operating cash requirements are greater than the Partnership’s financial resources, the Partnership may seek short-term, interest-bearing advances from the Managing Partner as needed. The Managing Partner, however, is not obligated to make loans to the Partnership. The Partnership does not intend to incur debt from banks or other outside sources or solicit capital from existing Unit holders or in the open market.
Capital Commitments and Contingencies
The Partnership’s primary needs for cash are for operating expenses, recompletion expenditures, and dismantlement and abandonment costs. To the extent it has discretion, the Partnership allocates available capital to investment in the Partnership’s properties so as to maximize production and resultant cash flow. The Partnership had no outstanding debt or lease commitments at December 31, 2022. The Partnership did not have any contractual obligations as of December 31, 2022, other than the liability for dismantlement and abandonment costs of its oil and gas properties. The Partnership has recorded a separate liability for this asset retirement obligation as discussed in Note 8-Asset Retirement Obligations in the Notes to the Consolidated Financial Statements set forth in Part II, Item 8 - “Financial Statements and Supplementary Data” of this Form 10-K.
During each of the last three years, the Partnership did not have meaningful cash outlays for oil and gas property additions as it did not participate in any new drilling projects. The Partnership paid cash settlements for ARO liabilities totaling approximately $27 thousand in 2022 and approximately $232 thousand in 2021.
Based on preliminary information available to the Partnership, it anticipates minimal 2023 capital expenditure levels for recompletions and other capital projects at South Timbalier 295. Additionally, $408 thousand is estimated to be spent in 2023 to decommission platforms at North Padre Island 969/976. Such estimates may change based on realized oil and gas prices, recompletion results, rates charged by contractors or changes by the operator to their development or abandonment plans.
Because of significant production impacts related to pipeline interruptions, volatility in commodity prices in recent years, and the need to reserve cash for future asset retirement obligations, the Partnership did not make any distributions to the Investing Partners during 2022 or 2021.
The amount of future distributions will be dependent on actual and expected production levels, realized and anticipated oil and gas prices, expected recompletion expenditures, and prudent cash reserves for future dismantlement and abandonment costs that will be incurred after the Partnership’s reserves are depleted. The Partnership’s goal is to maintain cash and cash equivalents in the Partnership at least sufficient to cover the undiscounted value of its future asset retirement obligations. The Partnership will continue to review available cash balances, cash requirements for plugging and abandonment activity, oil and gas prices realized by the Partnership for the sale of its production, and the level of recompletion activity to determine whether there are sufficient funds to make a distribution to Investing Partners in 2023.
On August 3, 2020, Fieldwood Energy LLC, the operator of the Partnership’s producing lease, and certain of its affiliated debtors (collectively, Fieldwood) filed for protection under Chapter 11 of the United States Bankruptcy Code. On June 25, 2021, the United States Bankruptcy Court for the Southern District of Texas (Houston Division) entered an order confirming Fieldwood’s bankruptcy plan. On August 27, 2021, Fieldwood’s bankruptcy plan became effective. Pursuant to the plan, Fieldwood separated its ownership in and operatorship of the Partnership’s producing lease, together with several of Fieldwood’s other leases, into a standalone company (GOM Shelf, LLC), which will continue to perform Fieldwood’s obligations with respect to the Partnership’s properties. The reorganization of Fieldwood under the plan is not expected to have any material adverse effect on the Partnership’s operations.
With respect to oil and gas operations in the Gulf of Mexico, the Bureau of Ocean Energy Management (BOEM) has issued Notice to Lessees (NTL) No. 2016-N01 pertaining to the obligations of companies to provide supplemental assurances for performance with respect to plugging, abandonment, decommissioning, and site clearance obligations associated with wells, platforms, structures, and facilities located upon or used in connection with such companies’ oil and gas leases. Under this NTL, the implementation of which is currently suspended and which may be revised by the BOEM, the Partnership may be required to provide additional security to BOEM with respect to plugging, abandonment, and decommissioning obligations relating to the Partnership’s current ownership interests in various Gulf of Mexico leases. The Partnership will likely satisfy such requirements through the provision of bonds or other forms of security. Management does not believe the ultimate satisfaction of the NTL requirements will adversely affect the Partnership’s overall liquidity.
Notice of Withdrawal and Right of Presentment
On March 22, 2019, Apache, as the Managing Partner of the Investment Partnership, gave notice of its intention to withdraw as Managing Partner of the Investment Partnership. The notice described the withdrawal process and certain notice periods required by that process. No party assumed the role of Managing Partner within the 120-day notice period specified by the notice of intention to withdraw. Consequently, Apache will oversee the process of winding up and liquidating the business and affairs of the Investment Partnership. Apache has not made a decision as to when it will complete the process to withdraw as Managing Partner.
On April 26, 2019, the Managing Partner determined that, during the withdrawal and dissolution process, it would be inconsistent with the Managing Partner’s fiduciary duties to purchase (or to cause the Investment Partnership to purchase) outstanding Units from the holders thereof pursuant to the right of presentment provided for in Sections 6.9 through 6.14 of the Partnership Agreement of the Investment Partnership (the Partnership Agreement). As a result of this determination by the Managing Partner, pursuant to Section 6.12 of the Partnership Agreement, the right of presentment has been terminated and Sections 6.9 through 6.14 have “become null and void and of no further force or effect” as provided in Section 6.12 of the Partnership Agreement.
Prior to terminating the right of presentment, the Investment Partnership had not made a repurchase under the right of presentment since 2008.
Off-Balance Sheet Arrangements
The Partnership does not currently utilize any off-balance sheet arrangements with unconsolidated entities to enhance liquidity and capital resource positions, or for any other purpose. Any future transactions involving off-balance sheet arrangements will be fully scrutinized by the Managing Partner and disclosed by the Partnership.
Insurance
The Managing Partner maintains insurance coverage that includes coverage for physical damage to the Partnership’s oil and gas properties, third-party liability, workers’ compensation and employers’ liability, general liability, sudden pollution and other coverage. The insurance coverage includes deductibles, which must be met prior to recovery. Additionally, the Managing Partner’s insurance is subject to exclusions and limitations, and there is no assurance that such coverage will adequately protect the Partnership against liability from all potential consequences and damages.
The Managing Partner’s various insurance policies also provide coverage for, among other things, liability related to negative environmental impacts of a sudden pollution, charterer’s legal liability and general liability, employer’s liability and auto liability. The Managing Partner’s service agreements, including drilling contracts, generally indemnify Apache and the Partnership for injuries and death of the service provider’s employees as well as contractors and subcontractors hired by the service provider.
Critical Accounting Policies and Estimates
The Partnership prepares its financial statements and the accompanying notes in conformity with accounting principles generally accepted in the United States (GAAP), which requires management to make estimates and assumptions about future events that affect the reported amounts in the financial statements and accompanying notes. Management identifies certain accounting policies as critical based on, among other things, their impact on the Partnership’s financial condition, results of operations or liquidity and the degree of difficulty, subjectivity, and complexity in their development. Critical accounting policies cover accounting matters that are inherently uncertain because the future resolution of such matters is unknown. The following is a discussion of the Partnership’s most critical accounting policies:
Reserve Estimates
Proved oil and gas reserves are the estimated quantities of natural gas, crude oil, condensate, and NGLs that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing conditions, operating conditions, and government regulations.
Despite the inherent imprecision in these engineering estimates, the Partnership’s reserves have a significant impact on its financial statements. For example, the quantity of reserves could significantly impact the Partnership’s DD&A expense. The Partnership’s oil and gas properties are also subject to a “ceiling” limitation based in part on the quantity of its proved reserves. These reserves are also the basis for the Partnership’s supplemental oil and gas disclosures.
Reserves are calculated using an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12 months, held flat for the life of production, except where prices are defined by contractual arrangements.
The Partnership has elected not to disclose probable and possible reserves or reserve estimates based upon futures or other prices in this filing.
The Partnership’s estimate of proved oil and gas reserves are prepared by Ryder Scott Company, L.P. Petroleum Consultants, independent petroleum engineers, utilizing oil and gas price data and cost estimates provided by Apache as Managing Partner.
Asset Retirement Obligation (ARO)
The Partnership has obligations to remove tangible equipment and restore the land or seabed at the end of oil and gas production operations. These obligations may be significant in light of the Partnership’s limited operations and estimate of remaining reserves. The Partnership’s removal and restoration obligations are primarily associated with plugging and abandoning wells and removing and disposing of offshore oil and gas platforms. Estimating the future restoration and removal costs is difficult and requires management to make estimates and judgments because most of the removal obligations are many years in the future and asset removal technologies and costs are constantly changing, as are regulatory, political, environmental, safety and public relations considerations.
Asset retirement obligations associated with retiring tangible long-lived assets are recognized as a liability in the period in which a legal obligation is incurred and becomes determinable. This liability is offset by a corresponding increase in the carrying amount of the underlying asset. The ARO liability reflects the estimated present value of the amount of dismantlement, removal, site reclamation and similar activities associated with the Partnership’s oil and gas properties. The Partnership utilizes current retirement costs to estimate the expected cash outflows for retirement obligations. The cost of the tangible asset, including the initially recognized ARO, is depleted such that the cost of the ARO is recognized over the useful life of the asset.
Inherent in the present value calculation are numerous assumptions and judgments including the ultimate settlement amounts, inflation factors, credit adjusted discount rates, timing of settlement, and changes in the legal, regulatory, environmental and political environments. To the extent future revisions to these assumptions impact the present value of the existing ARO liability, a corresponding adjustment is made to the oil and gas property balance. Accretion expense is recognized over time as the discounted liability is accreted to its expected settlement value.

REPORT OF MANAGEMENT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
Management of the Partnership is responsible for the preparation and integrity of the consolidated financial statements appearing in this Form 10-K. The financial statements were prepared in conformity with GAAP and include amounts that are based on management’s best estimates and judgments.
Management of the Partnership is responsible for establishing and maintaining effective internal control over financial reporting as such term is defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended (Exchange Act). The Partnership’s and Managing Partner’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements. Our internal control over financial reporting is supported by appropriate reviews by management, written policies and guidelines, careful selection and training of qualified personnel and a written code of business conduct adopted by APA’s board of directors, applicable to all directors, officers, employees, and other individuals working for APA and its affiliates.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements and even when determined to be effective, can only provide reasonable assurance with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.
Management assessed the effectiveness of the Partnership’s internal control over financial reporting as of December 31, 2022. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013). Based on our assessment, management believes that the Partnership maintained effective internal control over financial reporting as of December 31, 2022.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Partners of Apache Offshore Investment Partnership
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Apache Offshore Investment Partnership (the Partnership) as of December 31, 2022 and 2021, the related statements of consolidated operations, cash flows and changes in partners’ capital for each of the three years in the period ended December 31, 2022, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Partnership at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.
Basis for Opinion
These financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on the Partnership’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Partnership is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Partnership's internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Depreciation, depletion and amortization of oil and gas properties
Description of the Matter At December 31, 2022, the carrying value of the Partnership’s oil and gas properties was $3,710,762 and depreciation, depletion and amortization (DD&A) expense was $390,497 for the year then ended. As described in Note 2, the Partnership follows the full-cost method of accounting for its investment in oil and gas properties. DD&A of the cost of proved oil and gas properties is calculated using the future gross revenue method based on proved oil and gas reserves, as estimated by independent petroleum engineers.
Proved oil and gas reserves are the estimated quantities of natural gas, crude oil, condensate, and natural gas liquids, that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing conditions, operating conditions, and government regulations. Significant judgment is required by the independent petroleum engineers in evaluating geological and engineering data when estimating proved oil and gas reserves. Estimating reserves also requires the selection of inputs, including oil and gas price assumptions, future operating and capital costs assumptions, and tax rates, among others. Because of the complexity involved in estimating proved oil and gas reserves, management engaged independent petroleum engineers to prepare the proved oil and gas reserve estimates as of December 31, 2022.
Auditing the Partnership’s DD&A calculation is complex because of the use of the work of the independent petroleum engineers and the evaluation of management’s determination of the inputs described above used by the engineers in estimating proved oil and gas reserves.
How We Addressed the Matter in Our Audit Our audit procedures included, among others, evaluating the professional qualifications and objectivity of the independent petroleum engineers used to prepare the proved oil and gas reserve estimates. In addition, in assessing whether we can use the work of the independent petroleum engineers, we evaluated the completeness and accuracy of the financial data and inputs described above used by the engineers in estimating proved oil and gas reserves by agreeing them to source documentation, and we identified and evaluated corroborative and contrary evidence. We also tested the mathematical accuracy of the DD&A calculation, including comparing the proved oil and gas reserve amounts used in the calculation to the Partnership’s reserve report.

APACHE OFFSHORE INVESTMENT PARTNERSHIP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. ORGANIZATION
Nature of Operations
Apache Offshore Investment Partnership, a Delaware general partnership (the Investment Partnership), was formed on October 31, 1983, consisting of Apache Corporation (Apache or Managing Partner) as Managing Partner and public investors (the Investing Partners). The Investment Partnership invested its entire capital in Apache Offshore Petroleum Limited Partnership, a Delaware limited partnership (the Operating Partnership). The primary business of the Investment Partnership is to serve as the sole limited partner of the Operating Partnership. The primary business of the Operating Partnership is to conduct oil and gas development and production operations. The Operating Partnership conducts the operations of the Investment Partnership. The accompanying financial statements include the accounts of both the Investment Partnership and Operating Partnership.
The Investing Partners purchased Units of Partnership Interests (Units) in the Investment Partnership at $150,000 per Unit, with five percent down and the balance in payments as called by the Investment Partnership. In 1989, the Investment Partnership determined that the full $150,000 per Unit was not needed, fixed the total calls at $85,000 per Unit, and released the Investing Partners from liability for future calls. The Investment Partnership invested, and will continue to invest, its entire capital in the Operating Partnership.
Apache is the managing partner of the Investment Partnership and the general partner of the Operating Partnership, and held approximately five percent of the 1,018.5 Units outstanding at December 31, 2022. As used hereafter, the term “Partnership” refers to the Investment Partnership or the Operating Partnership, as the case may be.
Except for an additional interest acquired in Matagorda Island Block 681 and 682 in 1992, the Partnership acquired its oil and gas interests through the purchase of an 85 percent interest in offshore properties acquired by Apache as a co-venturer in a series of oil and gas exploration, development and production activities on 87 federal lease tracts in the Gulf of Mexico, offshore Louisiana and Texas. The remaining 15 percent interest was purchased by an affiliated partnership or retained by Apache. As of December 31, 2022, the Partnership has only one active venture prospect at South Timbalier 295, located offshore Louisiana, with a 7.08 percent working interest.
The Partnership’s future financial condition and results of operations will depend largely upon prices received for its oil and natural gas production and the costs of developing and producing reserves. A substantial portion of the Partnership’s production is sold under market-sensitive contracts. Prices for oil and natural gas are subject to fluctuations in response to changes in supply, market uncertainty and a variety of factors beyond the Partnership’s control. These factors include worldwide political instability, the foreign supply of oil and natural gas, the price of foreign imports, the level of consumer demand, and the price and availability of alternative fuels.
Under the terms of the Partnership Agreement of the Investment Partnership (the Partnership Agreement), the Investing Partners receive 80 percent and Apache receives 20 percent of revenue. Lease operating, gathering and transportation, and administrative expenses are allocated to the Investing Partners and Apache in the same proportion as revenues. The Investing Partners receive 100 percent of the interest income earned on short-term cash investments. The Investing Partners generally pay for 90 percent and Apache generally pays for 10 percent of exploration and development costs and expenses incurred by the Partnership. However, intangible drilling costs, interest costs and fees or expenses related to the loans incurred by the Partnership are allocated 99 percent to the Investing Partners and one percent to Apache until such time as the amount so allocated to the Investing Partners equals 90 percent of the total amount of such costs, including such costs incurred by Apache prior to the formation of the Partnership.
Notice of Withdrawal
On March 22, 2019, Apache, as the Managing Partner of the Investment Partnership, gave notice of its intention to withdraw as Managing Partner of the Investment Partnership. The notice described the withdrawal process and certain notice periods required by that process. No party assumed the role of Managing Partner within the 120-day notice period specified by the notice of intention to withdraw. Consequently, Apache will oversee the process of winding up and liquidating the business and affairs of the Investment Partnership. Apache has not made a decision as to when it will complete the process to withdraw as Managing Partner.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Right of Presentment
In February 1994, an amendment to the Partnership Agreement created a right of presentment under which all Investing Partners had a limited and voluntary right to offer their Units to the Partnership twice each year to be purchased for cash.
On April 26, 2019, the Managing Partner determined that, during the withdrawal and dissolution process noted above, it would be inconsistent with the Managing Partner’s fiduciary duties to purchase (or to cause the Investment Partnership to purchase) outstanding Units from the holders thereof pursuant to the right of presentment provided for in Sections 6.9 through 6.14 of the Partnership Agreement. As a result of this determination by the Managing Partner, pursuant to Section 6.12 of the Partnership Agreement, the right of presentment was terminated for 2019 and future periods. Sections 6.9 through 6.14 have “become null and void and of no further force or effect” as provided in Section 6.12 of the Partnership Agreement.
Prior to terminating the right of presentment, the Investment Partnership had not made a repurchase under the right of presentment since 2008.

The preparation of financial statements in conformity with GAAP and the disclosure of contingent assets and liabilities requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Partnership bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances. The Partnership evaluates its estimates and assumptions on a regular basis. Actual results may differ from these estimates and assumptions used in preparation of its financial statements and changes in these estimates are recorded when known. Significant estimates with regard to these financial statements include the estimate of proved oil and gas reserve quantities and the related present value of estimated future net cash flows therefrom (see Note 10-Supplemental Oil and Gas Disclosures (Unaudited)) and the assessment of asset retirement obligations (see Note 8-Asset Retirement Obligation).
Cash Equivalents
The Partnership considers all highly liquid short-term investments with an original maturity of three months or less at the time of purchase to be cash equivalents. These investments are carried at cost, which approximates fair value. As of December 31, 2022 and 2021, the Partnership had $4.7 million and $4.2 million, respectively, of cash and cash equivalents.
Oil and Gas Properties
The Partnership follows the full-cost method of accounting for its investment in oil and gas properties for financial statement purposes. Under this method of accounting, the Partnership capitalizes all acquisition, exploration and development costs incurred for the purpose of finding oil and gas reserves. The amounts capitalized under this method include dry hole costs, leasehold costs, engineering, geological, exploration, development and other similar costs. All costs related to production and administrative functions are expensed in the period incurred. The Partnership includes the present value of its dismantlement, restoration, and abandonment costs within the capitalized oil and gas property balance as described in Note 8-Asset Retirement Obligation. Unless greater than 25 percent of the Partnership’s reserve volumes are sold, proceeds from the sale of oil and gas properties are accounted for as reductions to capitalized costs, and gains or losses are not recognized.
Capitalized costs of oil and gas properties are amortized on the future gross revenue method whereby depreciation, depletion and amortization (DD&A) expense is computed quarterly by dividing current period oil and gas sales by estimated future gross revenue from proved oil and gas reserves (including current period oil and gas sales) and applying the resulting rate to the net cost of evaluated oil and gas properties, including estimated future development costs.
APACHE OFFSHORE INVESTMENT PARTNERSHIP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Under the full-cost method of accounting, the Partnership limits the capitalized costs of proved oil and gas properties, net of accumulated DD&A, to the estimated future net cash flows from proved oil and gas reserves discounted at 10 percent, plus the lower of cost or fair value of unproved properties included in the costs being amortized, if any. This ceiling test is performed each quarter. If capitalized costs exceed this limit, the excess is charged to expense and reflected as additional DD&A in the accompanying statement of consolidated operations. Estimated future net cash flows are calculated using end-of-period costs and an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12 months, held flat for the life of the production, except where prices are defined by contractual arrangements. The Partnership did not record any write-downs of capitalized costs during 2022, 2021, or 2020. See Note 10-Supplemental Oil and Gas Disclosures (Unaudited) for a discussion on the calculation of estimated future net cash flows.
Asset Retirement Costs and Obligation
The initial estimated asset retirement obligation related to property and equipment is recorded as a liability at its fair value, with an offsetting asset retirement cost recorded as an increase to oil and gas properties on the consolidated balance sheet. If the fair value of the recorded asset retirement obligation changes, a revision is recorded to both the asset retirement obligation and the asset retirement cost. Revisions in estimated liabilities can result from changes in estimated inflation rates, changes in service and equipment costs and changes in the estimated timing of settling asset retirement obligations. Accretion expense on the liability is recognized over the estimated productive life of the related assets.
Revenue Recognition
The Partnership applies the provisions of Accounting Standards Codification 606 for revenue recognition to contracts with customers. Sales of crude oil, natural gas, and natural gas liquids (NGLs) are included in revenue when production is sold to a customer in fulfillment of performance obligations under the terms of agreed contracts. Performance obligations primarily comprise delivery of oil, gas, or NGLs at a delivery point, as negotiated within each contract. Each barrel of oil, MMBtu of natural gas, or other unit of measure is separately identifiable and represents a distinct performance obligation to which the transaction price is allocated. Performance obligations are satisfied at a point in time once control of the product has been transferred to the customer. The Partnership considers a variety of facts and circumstances in assessing the point of control transfer, including but not limited to: whether the purchaser can direct the use of the hydrocarbons, the transfer of significant risks and rewards, the Partnership’s right to payment, and transfer of legal title. In each case, the term between delivery and when payments are due is not significant.
Apache, as Managing Partner of the Partnership, markets the Partnership’s share of oil production from South Timbalier 295, the Partnership’s only source of oil and gas revenue. Apache primarily markets to major oil companies, marketing and transportation companies, and refiners at current index prices, adjusted for quality, transportation, and market reflective differentials. The Partnership markets all other production under the joint operating agreements with the operator of its properties. The operator seeks and negotiates oil and gas marketing arrangements with various marketers and purchasers. These contracts provide for sales that are priced at prevailing market prices.
In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13, “Financial Instruments-Credit Losses.” The standard changes the impairment model for trade receivables, held-to-maturity debt securities, net investments in leases, loans, and other financial assets measured at amortized cost. This ASU requires the use of a new forward-looking “expected loss” model compared to the previous “incurred loss” model, resulting in accelerated recognition of credit losses. The Partnership adopted this update in the first quarter of 2022. The adoption and implementation of this ASU did not have a material impact on the the Partnership’s financial statements.
The Partnership records trade accounts receivable for its unconditional rights to consideration arising under sales contracts with customers, which is measured at amortized cost net of any allowance for credit losses. The Partnership routinely assesses the collectability of all material trade and other receivables. The Partnership would accrue an allowance for expected credit losses when, based on the judgment of management, it is probable that a receivable will not be collected and the amount of any expected credit losses may be reasonably estimated. As of December 31, 2022, the carrying amounts of trade accounts receivables approximate fair value because of the short-term nature of these instruments. Receivables from contracts with customers totaled $259,936 and nil as of December 31, 2022 and 2021, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
The Partnership has concluded that disaggregating revenue by product appropriately depicts how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. The table below presents the total oil, gas, and NGLs revenues of the Partnership for the years ended December 31, 2022, 2021 and 2020:
For the Year Ended December 31,
2022 2021 2020
Oil $ 1,486,731 $ 400,224 $ 532,261
Gas $ 227,267 52,273 70,999
NGLs $ 40,555 15,941 15,901
Total Oil and Gas Sales Revenue $ 1,754,553 $ 468,438 $ 619,161
The Partnership did not have any revenue from non-customers.
Net Income (Loss) Per Investing Unit
The net income (loss) per Investing Partner Unit is calculated by dividing the aggregate Investing Partners’ net income (loss) for the period by the number of weighted average Investing Partner Units outstanding for that period.
Income Taxes
The profit or loss of the Partnership for federal income tax reporting purposes is included in the income tax returns of the partners. Accordingly, no recognition has been given to income taxes in the accompanying financial statements.
Receivable from/Payable to Apache Corporation
The receivable from/payable to Apache Corporation, the Partnership’s Managing Partner, represents the net result of the Investing Partners’ revenue and expenditure transactions in the current month. Generally, cash in this amount will be paid by Apache to the Partnership or transferred to Apache in the month after the Partnership’s transactions are processed and the net results of operations are determined.
Maintenance and Repairs
Maintenance and repairs are charged to expense as incurred.

The Partnership’s aggregate DD&A expense as a percentage of oil and gas sales for 2022, 2021, and 2020 was 22 percent, 35 percent and 32 percent, respectively.
5. MAJOR CUSTOMER AND RELATED PARTIES INFORMATION
Revenues received from major third-party customers that equaled ten percent or more of oil and gas sales are discussed below. No other third-party customers individually accounted for ten percent or more of oil and gas sales.
Remittances from QuarterNorth Energy LLC (formerly Fieldwood Energy LLC) accounted for 15 percent, 15 percent and 14 percent of the Partnership’s oil and gas sales for the years 2022, 2021 and 2020, respectively. During December 2022, Commodore Offshore LLC took over as the third-party contract operator at South Timbalier 295. Approximately 85 percent, 85 percent and 86 percent of the Partnership’s oil and gas sales in 2022, 2021 and 2020, respectively, were to Chevron Products Company.
The Partnership’s revenues are derived principally from uncollateralized sales to customers in the oil and gas industry; therefore, customers may be similarly affected by changes in economic and other conditions within the industry. The Partnership has not experienced material credit losses on such sales.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
6. FAIR VALUE MEASUREMENTS
Certain assets and liabilities are reported at fair value on a recurring basis in the Partnership’s consolidated balance sheet. As of December 31, 2022 and December 31, 2021, the carrying amounts of cash, cash equivalents, accounts receivable, and accounts payable were determined to approximate fair value because of the short-term nature or maturity of these instruments.
7. COMMITMENTS AND CONTINGENCIES
Litigation - The Partnership is subject to governmental and regulatory controls arising in the ordinary course of business. It is the opinion of Apache’s management that all claims and litigation involving the Partnership are not likely to have a material adverse effect on its financial position or results of operations.
Environmental - The Partnership, as an owner or lessee of interests in oil and gas properties, is subject to various federal, state and local laws and regulations relating to discharge of materials into, and protection of, the environment. These laws and regulations may, among other things, impose liability on the lessee under an oil and gas lease for the cost of pollution clean-up resulting from operations and subject the lessee to liability for pollution damages. Apache maintains insurance coverage on the Partnership’s properties, which it believes is customary in the industry, although the Partnership is not fully insured against all environmental risks.
On August 3, 2020, Fieldwood Energy LLC, the operator of the Partnership’s producing lease, and certain of its affiliated debtors (collectively, Fieldwood) filed for protection under Chapter 11 of the United States Bankruptcy Code. On June 25, 2021, the United States Bankruptcy Court for the Southern District of Texas (Houston Division) entered an order confirming Fieldwood’s bankruptcy plan. On August 27, 2021, Fieldwood’s bankruptcy plan became effective. Pursuant to the plan, Fieldwood separated its ownership in, and operatorship of, the Partnership’s producing lease, together with several of Fieldwood’s other leases, into a standalone company (GOM Shelf, LLC), which will continue to perform Fieldwood’s obligations with respect to the Partnership’s properties. The reorganization of Fieldwood under the plan is not expected to have any material adverse effect on the Partnership’s operations.
With respect to oil and gas operations in the Gulf of Mexico, the Bureau of Ocean Energy Management (BOEM) has issued Notice to Lessees (NTL) No. 2016-N01 pertaining to the obligations of companies to provide supplemental assurances for performance with respect to plugging, abandonment, decommissioning, and site clearance obligations associated with wells, platforms, structures, and facilities located upon or used in connection with such companies’ oil and gas leases. Under this NTL, the implementation of which is currently suspended and which may be revised by the BOEM, the Partnership may be required to provide additional security to BOEM with respect to plugging, abandonment, and decommissioning obligations relating to the Partnership’s current ownership interests in various Gulf of Mexico leases. The Partnership will likely satisfy such requirements through the provision of bonds or other forms of security.
8. ASSET RETIREMENT OBLIGATION
The following table describes the changes to the Partnership’s asset retirement obligation (ARO) liability for the years ended December 31, 2022 and 2021:
2022 2021
Asset retirement obligation at beginning of year $ 1,814,060 $ 1,384,524
Accretion expense 81,770 52,858
Liabilities settled (26,934) (294,218)
Revisions in estimated liabilities (423,383) 670,896
Asset retirement obligation at end of year $ 1,445,513 $ 1,814,060
Less current portion (408,339) (450,996)
Asset retirement obligation, long-term $ 1,037,174 $ 1,363,064
The ARO liability reflects the estimated present value of the amount of dismantlement, removal, site reclamation, and similar activities associated with the Partnership’s oil and gas properties. The Partnership utilizes estimates from property operators and current market costs to estimate the expected cash outflows for retirement obligations. The Partnership estimates the ultimate productive life of the properties, a risk-adjusted discount rate, and an inflation factor in order to determine the current present value of this obligation. To the extent future revisions to these assumptions impact the present value of the existing ARO liability, a corresponding adjustment is made to the oil and gas property balance.
APACHE OFFSHORE INVESTMENT PARTNERSHIP
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Liabilities settled primarily relate to individual wells plugged and abandoned and platform decommissioning during the periods presented. The current portion of the ARO liability represents the retirement obligation expected to be incurred in the next twelve months.
During 2021, the upward revision in abandonment liabilities primarily represented higher estimated costs and increased inflation assumptions for South Timbalier 295. During 2022, as certain cost data and assessments became available from increased decommissioning activity on GOM Shelf LLC properties, the Partnership further updated and refined its estimates for abandonment liabilities. This resulted in a downward revision in estimated abandonment liabilities for South Timbalier 295.
Decommissioning and abandonment activities began at Ship Shoal 258/259 upon cessation of the lease in 2018 and were substantially completed during 2021.
9. TAX-BASIS FINANCIAL INFORMATION
A reconciliation of ordinary income for federal income tax reporting purposes to net income under GAAP is as follows:
2022 2021 2020
Net partnership ordinary income (loss) for federal income tax reporting purposes $ 1,057,799 $ (801,635) $ (549,623)
Plus: Items of current expense for tax reporting purposes only -
Intangible drilling cost (38,318) 38,318 9
Dismantlement and abandonment cost (24,907) 294,218 415,710
Tax depreciation 52,909 27,790 53,908
(10,316) 360,326 469,627
Less: full cost DD&A expense (390,497) (162,564) (200,045)
Less: asset retirement obligation accretion (81,770) (52,858) (52,943)
Net income (loss) $ 575,216 (656,731) (332,984)
The Partnership’s tax basis in net oil and gas properties at December 31, 2022, and 2021 was $2,408,881 and $3,260,012, respectively, lower than the carrying value of oil and gas properties under full cost accounting. The difference reflects the timing deductions for depreciation, depletion and amortization, intangible drilling costs and dismantlement and abandonment costs. For federal income tax reporting, the Partnership had capitalized syndication cost of $8,660,878 at each of December 31, 2022 and 2021.
A reconciliation of liabilities for federal income tax reporting purposes to liabilities under GAAP is as follows:
December 31,
2022 2021
Liabilities for federal income tax purposes $ 102,638 $ 348,800
Asset retirement liability 1,445,513 1,814,060

10. SUPPLEMENTAL OIL AND GAS DISCLOSURES (Unaudited)
Oil and Gas Reserve Information
Proved oil and gas reserves are the estimated quantities of natural gas, crude oil, condensate, and NGLs that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing conditions, operating conditions, and government regulations.
There are numerous uncertainties inherent in estimating quantities of proved reserves and projecting future rates of production and timing of development expenditures. The following reserve data represents estimates only and should not be construed as being exact.

Oil includes crude oil and condensate.
All the Partnership’s reserves as of December 31, 2022 are located on federal lease tracts in the Gulf of Mexico, offshore Louisiana. Approximately 91 percent of the Partnership’s current proved developed reserves on a barrels of oil equivalent basis are classified as proved not producing. These reserves relate to zones that are either behind pipe, or that have been completed but not yet produced or zones that have been produced in the past, but are now not producing due to mechanical reasons. These reserves may be regarded as less certain than producing reserves because they are frequently based on volumetric calculations rather than performance data. Future production associated with behind pipe reserves is scheduled to follow depletion of the currently producing zones in the same wellbores. It should be noted that additional capital will have to be spent to access these reserves. The capital and economic impact of production timing is reflected in the Partnership’s standardized measure under Future Net Cash Flows.
Future Net Cash Flows
Future cash inflows as of December 31, 2022, 2021, and 2020 were calculated using an unweighted arithmetic average of oil and gas prices in effect on the first day of each month in the respective year, except where prices are defined by contractual arrangements. Operating costs, production and ad valorem taxes and future development costs are based on current costs with no escalation.
The following table sets forth unaudited information concerning future net cash flows from proved oil and gas reserves. As the Partnership pays no income taxes, estimated future income tax expenses are omitted. This information does not purport to present the fair value of the Partnership’s oil and gas assets, but does present a standardized disclosure concerning possible future net cash flows that would result under the assumptions used.

ITEM 10. DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE
ITEM 10. DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE
The Partnership has no officers or directors. All of the Partnership’s management functions are performed by Apache, the Managing Partner of the Partnership. On March 1, 2021, Apache consummated a holding company reorganization (the Holding Company Reorganization), pursuant to which, Apache became a direct, wholly-owned subsidiary of APA Corporation (APA), all of Apache’s outstanding shares were automatically converted into equivalent corresponding shares of APA, APA became the successor issuer to Apache pursuant to Rule 12g-3(a) under the Securities Exchange Act of 1934, as amended (the Exchange Act), and APA replaced Apache as the public company trading on the Nasdaq Global Select Market under the ticker symbol “APA.”
Executive Officers of Apache
Following consummation of the Holding Company Reorganization, the executive officers of APA also serve as executive officers of Apache, with each officer having the same title at both companies. Information concerning the executive officers of APA set forth under the caption “Information About Our Executive Officers” in the proxy statement relating to the 2023 annual meeting of stockholders of APA (the APA Proxy Statement) is incorporated herein by reference.
