1.Organization and Summary of Significant Accounting Policies

Organization

The Ridgewood Energy Y Fund, LLC (the “Fund”), a Delaware limited liability company, was formed on March 25, 2008 and operates pursuant to a limited liability company agreement (the “LLC Agreement”) dated as of May 1, 2008 by and among Ridgewood Energy Corporation (the “Manager”) and the shareholders of the Fund, which addresses matters such as the authority and voting rights of the Manager and shareholders, capitalization, transferability of membership interests, participation in costs and revenues, distribution of assets and dissolution and winding up. The Fund was organized to primarily acquire interests in oil and gas properties located in the United States offshore waters of Texas, Louisiana and Alabama in the Gulf of Mexico.

The Manager has direct and exclusive control over the management of the Fund’s operations. The Manager performs, or arranges for the performance of, the management, advisory and administrative services required for the Fund’s operations. Such services include, without limitation, the administration of shareholder accounts, shareholder relations, the preparation, review and dissemination of tax and other financial information and the management of the Fund’s investments in projects. In addition, the Manager provides office space, equipment and facilities and other services necessary for the Fund’s operations. The Manager also engages and manages contractual relations with unaffiliated custodians, depositories, accountants, attorneys, corporate fiduciaries, insurers, banks and others as required. See Notes 2 and 3.

Basis of Presentation

These unaudited interim condensed financial statements have been prepared by the Fund’s management in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in the opinion of management, contain all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the Fund’s financial position, results of operations, changes in members’ capital and cash flows for the periods presented. Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted in these unaudited interim condensed financial statements. The financial position, results of operations, changes in members’ capital and cash flows for the periods presented herein are not necessarily indicative of future financial results. These unaudited interim condensed financial statements should be read in conjunction with the Fund’s December 31, 2020 financial statements and notes thereto included in the Fund’s Annual Report on Form 10-K (“2020 Annual Report”) filed with the Securities and Exchange Commission (“SEC”). The year-end condensed balance sheet data was derived from audited financial statements for the year ended December 31, 2020, but does not include all annual disclosures required by GAAP.

Use of Estimates

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expense during the reporting period. On an ongoing basis, management reviews its estimates, including those related to the fair value of financial instruments, depletion and amortization, determination of proved reserves, impairment of long-lived assets and asset retirement obligations. Actual results may differ from those estimates.

Summary of Significant Accounting Policies

The Fund has provided discussion of significant accounting policies in Note 1 of “Notes to Financial Statements” – “Organization and Summary of Significant Accounting Policies” contained in Item 8. “Financial Statements and Supplementary Data” within its 2020 Annual Report. There have been no significant changes to the Fund’s significant accounting policies during the three and sixnine months ended JuneSeptember 30, 2021.

Fair Value Measurements

The Fund follows the accounting guidance for fair value measurement for measuring fair value of assets and liabilities in its financial statements. The Fund’s financial assets and liabilities consist of cash and cash equivalents, salvage fund, production receivable, due from affiliate, other current assets, investment in Delta House, due to operators and accrued expenses. Except for investment in Delta House, the carrying amounts of these financial assets and liabilities approximate fair value due to their short-term nature.

The Fund’s investment in Delta House is valued using the measurement alternative for investment in other entities (see Investment in Delta House below for additional information). The Fund also applies the provisions of the fair value measurement accounting guidance to its non-financial assets and liabilities, such as oil and gas properties and asset retirement obligations, on a non-recurring basis.

Investment in Delta House

The Fund has investments in Delta House Oil and Gas Lateral, LLC and Delta House FPS, LLC (collectively “Delta House”), legal entities that own interests in a deepwater floating production system operated by Murphy Exploration & Production Company - USA. The investment in Delta House is valued using the measurement alternative to record the investment at cost, less impairment and plus or minus subsequent adjustments for observable price changes with change in basis reported in current earnings. At each reporting period, the Fund reviews its investment in Delta House to evaluate whether the investment is impaired. During each of the three and sixnine months ended JuneSeptember 30, 2021 and 2020, there were no impairments of the Fund’s investment in Delta House.

Asset Retirement Obligations

For oil and gas properties, there are obligations to perform removal and remediation activities when the properties are retired. Upon the determination that a property is either proved or dry, a retirement obligation is incurred. The Fund recognizes the fair value of a liability for an asset retirement obligation in the period incurred based on expected future cash outflows required to satisfy the obligation discounted at the Fund’s credit-adjusted risk-free rate. Plug and abandonment costs associated with unsuccessful projects are expensed as dry-hole costs. Annually, or more frequently if an event occurs that would dictate a change in assumptions or estimates underlying the obligations, the Fund reassesses its asset retirement obligations to determine whether any revisions to the obligations are necessary. The Fund maintains a salvage fund to provide for the funding of future asset retirement obligations. The following table presents changes in asset retirement obligations for the following periods:

During the sixnine months ended JuneSeptember 30, 2021, the Fund recorded credits to depletion expense totaling $0.1$0.6 million whichprimarily related to an adjustment to the asset retirement obligation for a fully depleted property.

Revenue Recognition

Oil and gas revenues from contracts with customers are recognized at the point when control of oil and natural gas is transferred to the customers in accordance with Accounting Standard Codification Topic 606, Revenue from Contracts with Customers. Revenues from the sale of natural gas liquid are included within gas revenues. The Fund’s oil and natural gas generally are sold to its customers at prevailing market prices based on an index in which the prices are published, adjusted for pricing differentials, quality of oil and pipeline allowances. Under the Fund’s oil and natural gas contracts, each unit of oil and natural gas represents a separate performance obligation; therefore, future volumes are wholly unsatisfied and the transaction price related to the remaining performance obligations is the variable index-based price attributable to each unit of oil and natural gas that is transferred to the customer. The Fund invoices customers once its performance obligations have been satisfied, at which point the payment is unconditional. Accordingly, the Fund’s oil and natural gas contracts do not give rise to contract assets or liabilities. The receivables related to the Fund’s oil and gas revenue are included within “Production receivable” on the Fund’s balance sheets.

Other revenue is generated from the Fund’s production handling, gathering and operating services agreement with affiliated entities and other third parties. The Fund earns a fee for its services and recognizes these fees as revenue at the time its performance obligations are satisfied as the control of oil and natural gas is never transferred to the Fund, thus there are no unsatisfied performance obligations. The Fund’s project operator performs joint interest billing once the performance obligations have been satisfied, at which point the payment is unconditional. Accordingly, the Fund’s production handling, gathering and operating services agreement with affiliated entities and other third parties does not give rise to contract assets or liabilities. The receivables related to the Fund’s proportionate share of revenue from affiliates are included within “Due from affiliate” on the Fund’s balance sheets. The receivables related to the Fund’s proportionate share of revenue from third parties are presented as a reduction from “Due to operator” on the Fund’s balance sheets. The receivables are settled by issuance of a non-cash credit from the Beta Project operator to the Fund when the operator performs the joint interest billing of the lease operating expenses due from the Fund. However, if applying the joint interest billing credit results in a net credit balance due to the Fund, the Beta Project operator remits such balance in cash to the Fund.

The Fund also has an estimation process for revenue and related accruals, and any identified difference between its revenue estimates and actual revenue has not been significant. During each of the three and sixnine months ended JuneSeptember 30, 2021 and 2020, revenue recognized from performance obligations satisfied in previous periods was not significant.

Allowance for Credit Losses

The Fund is exposed to credit losses through the sale of oil and natural gas to customers. However, the Fund only sells to a small number of major oil and gas companies that have investment-grade credit ratings. Based on historical collection experience, current and future economic and market conditions and a review of the current status of customers' production receivables, the Fund has not recorded an expected loss allowance as there are no past due receivable balances or projected credit losses. The Fund considered the current and expected future economic and market conditions surrounding the Coronavirus (“COVID-19”) pandemic and determined based on the composition of its customer base, there was no related credit loss impact.

Impairment of Long-Lived Assets

The Fund reviews the carrying value of its oil and gas properties for impairment whenever events and circumstances indicate that the recorded carrying value of its oil and gas properties may not be recoverable. Recoverability is evaluated by comparing estimated future net undiscounted cash flows to the carrying value of the oil and gas properties at the time of the review. If the carrying value exceeds the estimated future net undiscounted cash flows, the carrying value of the oil and gas properties is impaired, and written down to fair value. Fair value is determined using valuation techniques that include both market and income approaches and use Level 3 inputs. The fair value determinations require considerable judgment and are sensitive to change. Different pricing assumptions, estimates of oil and natural gas reserves and future development costs or discount rates could result in a significant impact on the amount of impairment.

There were no impairments of oil and gas properties during each of the three and sixnine months ended JuneSeptember 30, 2021 and 2020. Fluctuations in oil and natural gas commodity prices may impact the fair value of the Fund’s oil and gas properties. In addition, significant declines in oil and natural gas commodity prices could reduce the quantities of reserves that are commercially recoverable, which could result in impairment.

Recent Accounting Pronouncements

The Fund has considered recent accounting pronouncements issued during the sixnine months ended JuneSeptember 30, 2021 or through the filing of this report, and the Fund has not identified new standards that it believes will have an impact on the Fund’s financial statements.

2. Related Parties

Pursuant to the terms of the LLC Agreement, the Manager is entitled to receive an annual management fee, payable monthly, of 2.5% of total capital contributions, net of cumulative dry-hole well costs incurred by the Fund and fully depleted project investments, however, the Manager is permitted to waive all or a portion of the management fee at its own discretion. Therefore, all or a portion of the management fee may be temporarily waived to accommodate the Fund’s short-term commitments. Management fees during each of the three and sixnine months ended JuneSeptember 30, 2021 and JuneSeptember 30, 2020 were $0.2 million and $0.5$0.7 million, respectively.

The Manager is also entitled to receive 15% of the cash distributions from operations made by the Fund. Distributions paid to the Manager during the three and sixnine months ended JuneSeptember 30, 2021 were $0.2$0.3 million and $0.4$0.7 million, respectively. The Fund did not pay distributions during the three months ended June 30, 2020. Distributions paid to the Manager during the sixthree and nine months ended JuneSeptember 30, 2020 were $0.2 million.$0.1 million and $0.3 million, respectively.

The Fund utilizes Beta Sales and Transport, LLC and DH Sales and Transport, LLC, wholly-owned subsidiaries of the Manager, to facilitate the transportation and sale of oil and natural gas produced from the Beta, Diller and Marmalard projects.

The Fund and other third-party working interest owners in the Beta Project are parties to a production handling, gathering and operating services agreement (“PHA”) with Ridgewood Claiborne, LLC, a wholly-owned entity of Ridgewood Energy Oil & Gas Fund II, L.P. (“Institutional Fund II”), and other third-party working interest owners in the Claiborne Project. On September 23, 2020, a third-party working interest owner of the Claiborne Project executed a consent letter to assign the rights to the services under the PHA to Ridgewood Rattlesnake, LLC, a wholly-owned entity of Ridgewood Energy Oil & Gas Fund III, L.P. (“Institutional Fund III”). Institutional Fund II and Institutional Fund III are entities that are managed by the Fund’s Manager. During the three and sixnine months ended JuneSeptember 30, 2021, the Fund earned $42$26 thousand and $0.1 million, respectively, representing its proportionate share of the production handling fees earned from Institutional Fund II and Institutional Fund III, which is included within “Other revenue” on the Fund’s statements of operations. During the three and sixnine months ended JuneSeptember 30, 2020, the Fund earned $16$31 thousand and $29 thousand,$0.1 million, respectively, representing its proportionate share of the production handling fees earned from Institutional Fund II, which is included within “Other revenue” on the Fund’s statements of operations. As of JuneSeptember 30, 2021 and December 31, 2020, the Fund’s receivables of $27$14 thousand and $21 thousand, respectively, related to the Fund’s proportionate share of revenue from Institutional Fund II and Institutional Fund III are included within “Due from affiliate” on the Fund’s balance sheets. The receivables are settled by issuance of a non-cash credit from the Beta Project operator to the Fund on behalf of the Claiborne Project working interest owners when the operator performs the joint interest billing of the lease operating expenses due from the Fund. However, if applying the joint interest billing credit results in a net credit balance due to the Fund, the Beta Project operator remits such balance in cash to the Fund.

At times, short-term payables and receivables, which do not bear interest, arise from transactions with affiliates in the ordinary course of business.

The Fund has working interest ownership in certain oil and natural gas projects, which are also owned by other entities that are likewise managed by the Manager.

3.Commitments and Contingencies

Capital Commitments

As of JuneSeptember 30, 2021, the Fund’s estimated capital commitments related to its oil and gas properties were $6.9$6.6 million (which include asset retirement obligations for the Fund’s projects of $3.8$3.2 million), of which $0.5$1.0 million is expected to be spent during the next twelve months primarily related to the recompletion work for the Beta Project and the settlement of asset retirement obligations for certain of the Fund’s projects and the recompletion work for the Beta Project.projects. Future results of operations and cash flows are dependent on the ongoing development of and revenues from production and sale of oil and gas from the Fund’s producing projects.

Based upon its current cash position, salvage fund and its current reserve estimates, the Fund expects cash flow from operations to be sufficient to cover its commitments and ongoing operations. Reserve estimates are projections based on engineering data that cannot be measured with precision, require substantial judgment, and are subject to frequent revision.

Impact from COVID-19

The COVID-19 pandemic remains a global health crisis and continues to cause uncertainty in financial and commodity markets. The ultimate extent of the impact of the COVID-19 pandemic and resulting market disruption to the Fund’s operating results and cash flows continue to be unknown and unpredictable. Although, oil and natural gas commodity prices have improved from historic lows in 2020, the period of low oil and natural gas commodity prices during 2020 negatively impacted cash flow generated by the Fund’s projects. However, because the Fund owns its oil and gas properties with no debt and these projects are long-lived assets that are expected to produce over many years with relatively low operating costs, the Fund believes that it is positioned to weather this period of uncertainty and volatility from the COVID-19 pandemic. If oil and natural gas commodity prices and the overall global economy, including financial markets therein, are further adversely impacted by the COVID-19 pandemic for a prolonged period, the Fund, its operators and other working interest partners’ financial performance results will be materially adversely affected, which could significantly affect the Fund’s liquidity, development of oil and gas and expected operating results. It is likely that estimates of oil and gas products that can be economically produced will be reduced, which increases the likelihood of future impairments and higher depletion rates.

Environmental and Governmental Regulations

Many aspects of the oil and gas industry are subject to federal, state and local environmental laws and regulations. The Manager and operators of the Fund’s properties are continually taking action they believe appropriate to satisfy applicable federal, state and local environmental regulations. However, due to the significant public and governmental interest in environmental matters related to those activities, the Manager cannot predict the effects of possible future legislation, rule changes, or governmental or private claims. As of JuneSeptember 30, 2021 and December 31, 2020, there were no known environmental contingencies that required adjustment to, or disclosure in, the Fund’s financial statements.

Oil and gas industry legislation and administrative regulations are periodically changed for a variety of political, economic, and other reasons. Any such future laws and regulations could result in increased compliance costs or additional operating restrictions, which could have a material adverse effect on the Fund’s operating results and cash flows. It is not possible at this time to predict whether such legislation or regulation, if proposed, will be adopted as initially written, if at all, or how legislation or new regulation that may be adopted would impact the Fund’s business.

BOEM Notice to Lessees on Supplemental BondingFinancial Assurance Requirements

On July 14, 2016, the Bureau of Ocean Energy Management (“BOEM”) issued a Notice to Lessees (“NTL 2016-N01”2016- N01”) that discontinued and materially replaced existing policies and procedures regarding financial security (i.e. supplemental bonding) for decommissioning obligations of lessees of federal oil and gas leases and owners of pipeline rights-of-way, rights-of userights-of-use and easements on the Outer Continental Shelf (“Lessees”). Generally, NTL 2016-N01 (i) ended the practice of excusing Lessees from providing such additional security where co-lessees had sufficient financial strength to meet such decommissioning obligations, (ii) established new criteria for determining financial strength and additional security requirements of such Lessees, (iii) provided acceptable forms of such additional security, and (iv) replaced the waiver system with one of self-insurance. The rule became effective as of September 12, 2016; however, on January 6, 2017, the BOEM announced that it was suspending the implementation timeline for six months in certain circumstances. On May 1, 2017, the Secretary of the U.S. Department of the Interior (“Interior”) directed the BOEM to complete a review of NTL 2016-N01, to provide a report to certain Interior personnel describing the results of the review and options for revising or rescinding NTL 2016-N01, and to keep the implementation timeline extension in effect pending the completion of the review of NTL 2016-N01 by the identified Interior personnel. On June 22, 2017,The BOEM is not currently implementing NTL 2016-N01 and its status is uncertain. Notwithstanding the BOEM announced that the implementation timeline extension will remain in effect pending the completion of the reviewuncertain status of NTL 2016-N01. As of June 30,2016-N01, BOEM had continued under existing law to review supplemental financial assurance requirements relative to sole liability properties (i.e., properties in which only one company is liable for decommissioning). However, on August 18, 2021, the BOEM has not liftedissued a Note to Stakeholders in which the BOEM stated that it was expanding its suspensionfinancial assurance efforts beyond sole liability projects to include “supplemental financial assurance of the implementationcertain high-risk, non-sole liability properties” (those properties with more than one company potentially liable for decommissioning costs). The BOEM identified (i) inactive properties, (ii) those with less than five years of NTL 2016-N01.production left, and (iii) those with damaged infrastructure, as being high-risk, non-sole liability properties and for which supplemental financial assurance may be required. The impact of NTL 2016-N01, if enforced without change or amendment,BOEM may require the Fund to fully secure all of its potential abandonment liabilities, to the BOEM’s satisfaction using one or more of the enumerated methods for doing so. Potentially thiswhich potentially could increase costs to the Fund if the Fund is required to obtain additional supplemental bonding, fund escrow accounts or obtain letters of credit.Fund.

On October 16, 2020, BOEM and the Bureau of Safety and Environmental Enforcement published a proposed new rule at 85 FR 65904 on Risk, Management, Financial Assurance and Loss Prevention, addressing the streamlining of evaluation criteria when determining whether oil, gas and sulfur leases, right-of-use and easement grant holders, and pipeline right-of-way grant holders may be required to provide bonds or other security above the prescribed amounts for base bonds to ensure compliance with the Outer Continental ShelfLessees’ obligations, primarily decommissioning obligations. The proposed rule was significantly less stringent with respect to financial assurance than NTL 2016-N01. To date, however, Interior has not issued a final rule but has indicated that it is reviewing the proposed rule. The Fund is not able to evaluate the impact of the proposed new rule on its operations or financial condition until thea final rule is issued.issued or some other definitive action is taken by the Interior or BOEM.

Insurance Coverage

The Fund is subject to all risks inherent in the oil and natural gas business. Insurance coverage as is customary for entities engaged in similar operations is maintained, but losses may occur from uninsurable risks or amounts in excess of existing insurance coverage. The occurrence of an event that is not insured or not fully insured could have a material adverse impact upon earnings and financial position. Moreover, insurance is obtained as a package covering all of the entities managed by the Manager. Depending on the extent, nature and payment of claims made by the Fund or other entities managed by the Manager, yearly insurance coverage may be exhausted and become insufficient to cover a claim by the Fund in a given year.

ITEM 2.              MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Cautionary Statement Regarding Forward-Looking Statements

Certain statements in this Quarterly Report on Form 10-Q (“Quarterly Report”) and the documents Ridgewood Energy Y Fund, LLC (the “Fund”) has incorporated by reference into this Quarterly Report, other than purely historical information, including estimates, projections, statements relating to the Fund’s business plans, strategies, objectives and expected operating results, and the assumptions upon which those statements are based, are “forward-looking statements” within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Such forward-looking statements are based on current expectations and assumptions and are subject to risks and uncertainties that may cause actual results to differ materially from the forward-looking statements. You are therefore cautioned against relying on any such forward-looking statements. Forward-looking statements can generally be identified by words such as “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “plan,” “target,” “pursue,” “may,” “will,” “will likely result,” and similar expressions and references to future periods. Examples of events that could cause actual results to differ materially from historical results or those anticipated include the impact on the Fund’s business and operations of the ongoing Coronavirus (“COVID-19”) pandemic and any other future widespread health emergencies or public health crises such as pandemics and epidemics, weather conditions, such as hurricanes, changes in market and other conditions affecting the pricing, production and demand of oil and natural gas, the cost and availability of equipment, and changes in domestic and foreign governmental regulations. Examples of forward-looking statements made herein include statements regarding projects, investments, insurance, capital expenditures and liquidity. Forward-looking statements made in this document speak only as of the date on which they are made. The Fund undertakes no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

Critical Accounting Policies and Estimates

There were no changes to the Fund’s critical accounting policies and estimates from those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2020.

Overview of the Fund’s Business

The Fund was organized primarily to acquire interests in oil and natural gas properties located in the United States offshore waters of Texas, Louisiana and Alabama in the Gulf of Mexico. The Fund’s primary investment objective is to generate cash flow for distribution to its shareholders by generating returns across a portfolio of oil and natural gas projects. Distributions to shareholders are made in accordance with the Fund’s limited liability company agreement (the “LLC Agreement”).

Ridgewood Energy Corporation (the “Manager”) is the Manager, and as such, has direct and exclusive control over the management of the Fund’s operations. The Manager performs, or arranges for the performance of, the management, advisory and administrative services required for the Fund’s operations. As compensation for its services, the Manager is entitled to an annual management fee, payable monthly, equal to 2.5% of the total capital contributions made by the Fund’s shareholders, net of cumulative dry-hole well costs incurred by the Fund and fully depleted project investments. The Fund does not currently, nor is there any plan to, operate any project in which the Fund participates. The Manager enters into operating agreements with third-party operators for the management of all exploration, development and producing operations, as appropriate. The Manager also participates in distributions.

Recent Developments

In March 2020, the World Health Organization categorized the outbreak of COVID-19 as a global pandemic, which resulted in a significant drop in oil demand caused by lockdown measures and industrial slowdown around the world. In addition, in March 2020, the failure of an alliance between the Saudi Arabia-led Organization of Petroleum Exporting Countries (“OPEC”) and Russia to reach an agreement on oil production volumes resulted in an oil “price war” and caused oil prices to collapse. Oil prices decreased to their lowest level in April 2020 as compared to the past several years as a result of the initial oil price war and significant decreases in oil demand caused by world-wide government-ordered lock-downs. On April 12, 2020, and throughout 2020, OPEC and Russia agreed and implemented oil production cuts to stabilize the oil market. Since then, the oil market has stabilized and strengthened with oil prices gradually rising throughout the rest of 2020. Oil prices have continued to strengthen into 2021 supported by a slow recovery in demand with the easing of lock-down measures and the rollout of COVID-19 vaccines, market-driven supply cutbacks in the upstream oil sector globally and the effective ongoing supply-side management by OPEC. Looking ahead, these factors indicate a balanced market by the second half of 2021. However, uncertainty still exists depending on actions taken by OPEC and non-OPEC countries in supporting a balanced global oil supply.

The ultimate extent of the impact of the COVID-19 pandemic and resulting market disruption to the Fund’s operating results and cash flows continue to be unknown and unpredictable. Although, oil and natural gas commodity prices have improved from historic lows in 2020, the period of low oil and natural gas commodity prices during 2020 negatively impacted cash flow generated by the Fund’s projects.  However, because the Fund owns its oil and gas properties with no debt and these projects are long-lived assets that are expected to produce over many years with relatively low operating costs, the Fund believes that it is positioned to weather this period of uncertainty and volatility from the COVID-19 pandemic. If oil and natural gas commodity prices and the overall global economy, including financial markets therein, are further adversely impacted by the COVID-19 pandemic for a prolonged period, the Fund, its operators and other working interest partners’ financial performance results will be materially adversely affected, which could significantly affect the Fund’s liquidity, development of oil and gas and expected operating results. It is likely that estimates of oil and gas products that can be economically produced will be reduced, which increases the likelihood of future impairments and higher depletion rates.

Commodity Price Changes

Changes in oil and natural gas commodity prices may significantly affect liquidity and expected operating results. Declines in oil and natural gas commodity prices not only reduce revenues and profits but could also reduce the quantities of reserves that are commercially recoverable and result in non-cash charges to earnings due to impairment.

Oil and natural gas commodity prices have been subject to significant fluctuations during the past several years. During first half of 2020, oil and natural gas commodity prices experienced significant volatility primarily attributable to the COVID-19 pandemic. The Fund anticipates price cyclicality in its planning and believes it is well positioned to withstand price volatility. The Fund will continue to closely manage and coordinate its capital spending estimates within its expected cash flows to provide for future development costs of its producing projects, as budgeted.  See “Results of Operations” under this Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Quarterly Report for more information on the average oil and natural gas prices received by the Fund during the three and sixnine months ended JuneSeptember 30, 2021 and 2020 and the effect of such average prices on the Fund’s results of operations. If oil and natural gas commodity prices are further adversely impacted by the COVID-19 pandemic for a prolonged period, the Fund’s results of operations and liquidity will be materially adversely impacted.

Market pricing for oil and natural gas is volatile and is likely to continue to be volatile in the future. This volatility is caused by numerous factors and market conditions that the Fund cannot control or influence. Therefore, it is impossible to predict the future price of oil and natural gas with any certainty. Factors affecting market pricing for oil and natural gas include:

Business Update

Information regarding the Fund’s current projects, all of which are located in the United States offshore waters in the Gulf of Mexico, is provided in the following table. See “Liquidity Needs” under this Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Quarterly Report for information regarding the funding of the Fund’s capital commitments.

Results of Operations

The following table summarizes the Fund’s results of operations during the three and sixnine months ended JuneSeptember 30, 2021 and 2020, and should be read in conjunction with the Fund’s financial statements and notes thereto included within Item 1. “Financial Statements” in Part I of this Quarterly Report.

Overview. The following table provides information related to the Fund’s oil and natural gas production and oil and gas revenue during the three and sixnine months ended JuneSeptember 30, 2021 and 2020. Natural gas liquid sales are included within gas sales.

The decrease in the number of wells producing during the sixnine months ended JuneSeptember 30, 2021 related to the Liberty Project, which reached the end of its productive life during first quarter 2020. The increasesdecreases in production days and oil and gas volumes noted in the table above were primarily related to the Diller and Marmalard projects, which were shut-in during May 2020 due to the low-price environment. Production from the wells returned in June 2020 at production levels prior to the shut-in. The increases were partially offset by the decrease in production days from the Beta Project during the three months ended June 30, 2021 as a result of the shut-in of production from one of itsthe project’s wells since May 2021 due to recompletion work.work coupled with the natural decline in production from the other wells. The decreasesrecompleted well returned to production in late-September 2021. In addition, the decrease in oil and gas sales volumes noted induring the table above were primarily attributable to the Beta Project, which is experiencing a natural decline in production coupled with the shut-in of one of its wells during second quarternine months ended September 30, 2021 due to recompletion work.  In addition, the decreases werewas also attributable to the Liberty Project, which reached the end of its productive life during first quarter 2020. The increase in production days during the nine months ended September 30, 2021 was primarily related to the Diller and Marmalard projects, which experienced significant periods of shut-ins during 2020 compared to 2021 due to storm-related safety shut-ins as a result of active storm systems passing through the Gulf of Mexico as well as due to the low-price environment and a mechanical issue at the Delta House production facility. This increase was partially offset by the decrease in production days from the Beta Project as a result of the shut-in of one of its wells due to recompletion work during 2021. See additional discussion in “Business Update” section above.

Oil and Gas Revenue. Oil and gas revenue during the three months ended JuneSeptember 30, 2021 was $2.1$1.6 million, an increase of $1.3$0.6 million from the three months ended June 30, 2020. The increase was primarily attributable to increased oil and gas prices.

Oil and gas revenue during the six months ended June 30, 2021 was $4.0 million, an increase of $1.2 million from the six months ended JuneSeptember 30, 2020. The increase was attributable to increased oil and gas prices totaling $1.6$0.7 million, partially offset by decreased sales volume totaling $0.4$0.1 million.

Oil and gas revenue during the nine months ended September 30, 2021 was $5.6 million, an increase of $1.9 million from the nine months ended September 30, 2020. The increase was attributable to increased oil and gas prices totaling $2.3 million, partially offset by decreased sales volume totaling $0.5 million.

See “Overview” above for factors that impact the oil and gas revenue volume and rate variances.

Other Revenue. Other revenue is generated from the Fund’s production handling, gathering and operating services agreement with affiliated entities and other third parties.

Depletion and Amortization. Depletion and amortization during the three months ended JuneSeptember 30, 2021 was $0.9$0.1 million, an increasea decrease of $0.3$0.4 million from the three months ended JuneSeptember 30, 2020. The increasedecrease was primarily attributable to an increase in the average depletion rate.

Depletion and amortization during the six months ended June 30, 2021 was $1.6 million, an increase of $0.3 million from the six months ended June 30, 2020. The increase was attributable to an increase in the average depletion rate totaling $0.5 million, partially offset by a decrease in production volumes totaling $0.1 million and an adjustment to the asset retirement obligation related to a fully depleted property totaling $0.6 million during third quarter 2021, partially offset by an increase in the average depletion rate totaling $0.2 million.

Depletion and amortization during the nine months ended September 30, 2021 was $1.7 million, a decrease of $0.1 million duringfrom the sixnine months ended JuneSeptember 30, 2021.2020. The decrease was primarily attributable to an adjustment to the asset retirement obligation related to a fully depleted property totaling $0.6 million during third quarter 2021 and a decrease in production volumes totaling $0.2 million, partially offset by an increase in the average depletion rate totaling $0.7 million.

The increases in the average depletion rates were primarily attributable to the changes in reserves estimates provided annually by the Fund’s independent petroleum engineers.engineers coupled with the higher cost of reserves from the Beta Project primarily due to the recompletion costs incurred for one of the project’s wells during 2021.

See “Overview” above for certain factors that impact the depletion and amortization volume and rate variances. Reserves estimates may also be impacted by significant declines in oil and natural gas commodity prices due to the COVID-19 pandemic, which could result in higher depletion rates.

Operating Expenses. Operating expenses represent costs specifically identifiable or allocable to the Fund’s wells, as detailed in the following table.

Lease operating expense and transportation and processing expense relate to the Fund’s producing projects. Workover expense represents costs to restore or stimulate production of existing reserves. During the three and nine months ended September 30, 2021, workover expense primarily related to the Marmalard Project. Insurance expense represents premiums related to the Fund’s projects, which vary depending upon the number of wells producing or drilling. Workover expense represents costs to restore or stimulate production of existing reserves. Accretion expense relates to the asset retirement obligations established for the Fund’s oil and gas properties.

Production costs, which include lease operating expense, transportation and processing expense and insurance expense, were $0.3$0.2 million ($7.518.35 per barrel of oil equivalent or “BOE”) and $0.6$0.8 million ($7.387.62 per BOE) during the three and sixnine months ended JuneSeptember 30, 2021, respectively, compared to $0.4$0.3 million ($11.619.00 per BOE) and $0.9$1.2 million ($10.3010.05 per BOE) during the three and sixnine months ended JuneSeptember 30, 2020, respectively.
