Accounting Policies [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1. Partnership Organization Energy 11, L.P. (together with its wholly-owned subsidiary, the “Partnership”) is a Delaware limited partnership formed to acquire producing and non-producing oil and natural gas properties onshore in the United States and to develop those properties. The initial capitalization of the Partnership of $1,000 occurred on July 9, 2013. The Partnership completed its best-efforts offering on April 24, 2017 with a total of approximately 19 million common units sold for gross proceeds of $374.2 million and proceeds net of offering costs of $349.6 million. As of December 31, 2023, the Partnership owns an approximate 24% non-operated working interest in 299 producing wells, an estimated approximate 18.5% non-operated working interest in 6 wells in various stages of the drilling and completion process and future development sites in the Sanish field located in Mountrail County, North Dakota (collectively, the “Sanish Field Assets”). Chord Energy Corporation (“Chord”, NASDAQ: CHRD), the product of a merger between Whiting Petroleum Corporation and Oasis Petroleum Inc., is one of the largest producers in the basin and operates substantially all of the Sanish Field Assets. The general partner of the Partnership is Energy 11 GP, LLC (the “General Partner”). The General Partner manages and controls the business affairs of the Partnership. The Partnership’s fiscal year ends on December 31.

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Note 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements of the Partnership have been prepared in accordance with United States generally accepted accounting principles (“US GAAP”). The consolidated financial statements include the accounts of the Partnership and its subsidiaries. Cash, Cash Equivalents and Restricted Cash and Cash Equivalents Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less. The fair market value of cash and cash equivalents approximates their carrying value. Cash balances may at times exceed federal depository insurance limits. Property and Depreciation, Depletion and Amortization The Partnership accounts for its oil and natural gas properties using the successful efforts method of accounting. Under this method, costs of productive exploratory wells, development dry holes and productive wells and undeveloped leases are capitalized. Oil and natural gas lease acquisition costs are also capitalized. Exploration costs, including personnel costs, certain geological and geophysical expenses and delay rentals for oil and natural gas leases, are charged to expense during the period the costs are incurred. Exploratory drilling costs are initially capitalized but charged to expense if and when the well is determined not to have found reserves in commercial quantities. The capitalized costs of oil and natural gas properties are depleted using the unit-of-production method on a field basis based on estimated proved developed and/or undeveloped oil, natural gas and NGL reserves. No gains or losses are recognized upon the disposition of proved oil and natural gas properties except in transactions such as the significant disposition of an amortizable base that significantly affects the unit–of–production amortization rate. Sales proceeds are credited to the carrying value of the properties. The application of the successful efforts method of accounting requires managerial judgment to determine the proper classification of wells designated as development or exploratory which will ultimately determine the proper accounting treatment of the costs incurred. The results from a drilling operation can take considerable time to analyze and the determination that commercial reserves have been discovered requires both judgment and industry experience. Wells may be completed that are assumed to be productive and actually deliver oil, natural gas and natural gas liquids in quantities insufficient to be economic, which may result in the abandonment of the wells at a later date. Wells are drilled that have targeted geologic structures that are both developmental and exploratory in nature, and an allocation of costs is required to properly account for the results. Delineation seismic incurred to select development locations within an oil and natural gas field is typically considered a development cost and capitalized, but often these seismic programs extend beyond the reserve area considered proved and management must estimate the portion of the seismic costs to expense. The evaluation of oil and natural gas leasehold acquisition costs requires managerial judgment to estimate the fair value of these costs with reference to drilling activity in a given area. Drilling activities in an area by other companies may also effectively condemn leasehold positions. Impairment The Partnership assesses its proved oil and natural gas properties for possible impairment whenever events or circumstances indicate that the recorded carrying value of the properties may not be recoverable. Such events include a projection of future reserves that will be produced from a field, the timing of this future production, future costs to produce the oil, natural gas and natural gas liquids and future inflation levels. If the carrying amount of the properties exceeds the sum of the estimated undiscounted future net cash flows, the Partnership recognizes an impairment expense equal to the difference between the carrying value and the fair value of the properties, which is estimated to be the expected present value of the future net cash flows. Estimated future net cash flows are based on existing reserves, forecasted production and cost information and management’s outlook of future commodity prices. Where probable and possible reserves exist, an appropriately risk adjusted amount of these reserves is included in the impairment evaluation. The underlying commodity prices used in the determination of our estimated future net cash flows are based on NYMEX forward strip prices at the end of the period, adjusted by field or area for estimated location and quality differentials, as well as other trends and factors that management believes will impact realizable prices. Future operating costs estimates are also developed based on a review of actual costs by field or area. Downward revisions in estimates of reserve quantities or expectations of falling commodity prices or rising operating costs could result in a reduction in undiscounted future cash flows and could indicate a property impairment. Use of Estimates Preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts and disclosures reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Of these estimates and assumptions, management considers the estimation of oil, natural gas and NGL reserves to be the most significant. These estimates affect the unaudited standardized measure disclosures, as well as depreciation, depletion and amortization (“DD&A”) and impairment calculations. On an annual basis, the Partnership’s independent consulting petroleum engineer, with assistance from the Partnership, prepares estimates of oil, natural gas and NGL reserves based on available geologic and seismic data, reservoir pressure data, core analysis reports, well logs, analogous reservoir performance history, production data and other available sources of engineering, geological and geophysical information. For DD&A purposes, and as required by the guidelines and definitions established by the Securities and Exchange Commission (“SEC”), the reserve estimates were based on average individual product prices during the 12-month period prior to December 31, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period excluding escalations based upon future conditions. For impairment purposes, projected NYMEX forward strip prices for oil, natural gas and NGL as estimated by management are used. Oil, natural gas and NGL prices are volatile and largely affected by worldwide production and consumption and are outside the control of management. Projected future oil, natural gas and NGL pricing assumptions are used by management to prepare estimates of oil, natural gas and NGL reserves used in formulating management’s overall operating decisions. The Partnership does not operate its oil and natural gas properties and, therefore, receives actual oil, natural gas and NGL sales volumes and prices (in the normal course of business) more than a month later than the information is available to the operators of the wells. This being the case, the most current available production data is gathered from the appropriate operators, and oil, natural gas and NGL index prices local to each well are used to estimate the accrual of revenue on these wells. The oil, natural gas and NGL sales revenue accrual can be impacted by many variables including rapid production decline rates, production curtailments by operators, the shut-in of wells with mechanical problems and rapidly changing market prices for oil, natural gas and NGLs. These variables could lead to an over or under accrual of oil, natural gas and NGL sales at the end of any particular quarter. However, the Partnership adjusts the estimated accruals of revenue to actual production in the period actual production is determined. Revenue Recognition The Partnership is bound by a joint operating agreement with the operator of each of its producing wells. Under the joint operating agreement, the Partnership’s proportionate share of production is marketed at the discretion of the operators. The Partnership typically satisfies its performance obligations upon transfer of control of its products and records the related revenue in the month production is delivered to the purchaser. As the Partnership does not operate its properties, it receives actual oil, natural gas, and NGL sales volumes and prices, net of costs incurred by the operators, two to three months after the date production is delivered by the operator. At the end of each month when the performance obligation is satisfied, the variable consideration can be reasonably estimated and amounts due from the Partnership’s operators are accrued in Oil, natural gas and natural gas liquids revenue receivable in the consolidated balance sheets. Variances between the Partnership’s estimated revenue and actual payments are recorded in the month the payment is received; differences have been and are insignificant. As a result, the variable consideration is not constrained. The Partnership has elected to utilize the practical expedient in ASC 606 that states the Partnership is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Each delivery of product represents a separate performance obligation; therefore, future volumes are wholly unsatisfied, and disclosure of the transaction price allocated to remaining performance obligations is not required. Virtually all of the Partnership’s contracts’ pricing provisions are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, quality of oil, natural gas and natural gas liquids and prevailing supply and demand conditions, so that prices fluctuate to remain competitive with other available suppliers. Accounts Receivable and Concentration of Credit Risk For the year ended December 31, 2023, the Partnership’s oil, natural gas and NGL sales were through two operators. Substantially all the Partnership’s accounts receivable is due from Chord, the largest operator of the Partnership’s oil and natural gas properties in North Dakota (operators have accounts receivable from purchasers of oil, natural gas and NGLs). Oil, natural gas and NGL sales receivables are generally unsecured. This industry and location concentration has the potential to impact the Partnership’s overall exposure to credit risk, in that the purchasers of the Partnership’s oil, natural gas and NGLs and the operators of the properties in which the Partnership has an interest may be similarly affected by changes in economic, industry or other conditions. At December 31, 2023, the Partnership did not reserve for bad debt expense, as all amounts are deemed collectible. Chord is the current operator of 99% of the Partnership’s producing properties. All oil and natural gas producing activities of the Partnership are in North Dakota and represent substantially all of the business activities of the Partnership. Asset Retirement Obligation The Partnership has significant obligations to remove tangible equipment and facilities and restore land at the end of oil and natural gas production operations. The removal and restoration obligations are primarily associated with site reclamation, dismantling facilities and plugging and abandoning wells. 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 contracts and regulations often have vague descriptions of what constitutes removal. Asset removal technologies and costs are constantly changing, as are regulatory, political, environmental, safety and public relations considerations. The Partnership records an asset retirement obligation (“ARO”) and capitalizes the asset retirement cost in oil and natural gas properties in the period in which the retirement obligation is incurred based upon the fair value of an obligation to perform site reclamation, dismantle facilities or plug and abandon wells. After recording these amounts, the ARO is accreted to its future estimated value using an assumed cost of funds and the additional capitalized costs are depreciated on a unit-of-production basis. 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 of these assumptions impact the present value of the existing asset retirement obligation, a corresponding adjustment is made to the oil and natural gas property balance. The following table shows the activity for the years ended December 31, 2023 and 2022, relating to the Partnership’s asset retirement obligations: Balance as of December 31, 2021 $ 1,791,341 Well additions 95,480 Accretion 97,588 Revisions in estimated cash flows (17,671 ) Balance as of December 31, 2022 1,966,738 Well additions 4,748 Accretion 107,855 Revisions in estimated cash flows (18,821 ) Balance as of December 31, 2023 $ 2,060,520 Income Tax The Partnership is taxed as a partnership for federal and state income tax purposes. Typically, the Partnership has not recorded a provision for income taxes since the liability for such taxes is that of each of the partners rather than the Partnership. In mid-2022, the Partnership was contacted by the state of North Dakota, which asserted that the Partnership has an obligation to make tax payments on behalf of certain non-resident partners. The Partnership reached a resolution with the state of North Dakota that entailed the Partnership making a payment of taxes on behalf of certain non-resident limited partners to the state for the tax years of 2021 and 2022. The Partnership made a payment of approximately $243,000 (approximately $0.013 per common unit) in May 2023 that settled the 2021 tax year. The Partnership recorded an estimate at December 31, 2022 of approximately $315,000 for the 2022 tax year. In addition, the Partnership recorded an estimated at December 31, 2023 of approximately $1.0 million for the 2023 tax year. Settlements for the 2022 and 2023 tax years are expected during 2024. The Partnership’s income tax returns are subject to examination by the federal and state taxing authorities, and changes, if any, could adjust the individual income tax of the partners. The Partnership has evaluated whether any material tax position taken will more likely than not be sustained upon examination by the appropriate taxing authority and believes that all such material tax positions taken are supportable by existing laws and related interpretations. Environmental Costs As the Partnership is directly involved in the extraction and use of natural resources, it is subject to various federal, state and local provisions regarding environmental and ecological matters. Compliance with these laws may necessitate significant capital outlays. The Partnership does not believe the existence of current environmental laws or interpretations thereof will materially hinder or adversely affect the Partnership’s business operations; however, there can be no assurances of future effects on the Partnership of new laws or interpretations thereof. Since the Partnership does not operate any wells where it owns an interest, actual compliance with environmental laws is controlled by the well operators, with the Partnership being responsible for its proportionate share of the costs involved. Environmental liabilities are recognized when it is probable that a loss has been incurred and the amount of that loss is reasonably estimable. Environmental liabilities, when accrued, are based upon estimates of expected future costs. At December 31, 2023 and 2022, there were no such costs accrued. Net Income Per Common Unit Basic net income per common unit is computed as net income divided by the weighted average number of common units outstanding during the period. Diluted net income per unit is calculated after giving effect to all potential common units that were dilutive and outstanding for the period. There were no common units with a dilutive effect for the years ended December 31, 2023 and 2022. As a result, basic and diluted outstanding common units were the same. The Class B Units and Incentive Distribution Rights are not included in net income per common unit until such time that it is probable Payout (as discussed in Note 7) would occur.

Oil and Gas Property [Abstract]
Oil and Gas Properties [Text Block]	Note 3. Oil and Gas Investments On December 18, 2015, the Partnership completed its first purchase in the Sanish field, acquiring an approximate 11% non-operated working interest in the Sanish Field Assets for approximately $159.6 million. On January 11, 2017, the Partnership closed on its second purchase in the Sanish field, acquiring an additional approximate 11% non-operated working interest in the Sanish Field Assets for approximately $128.5 million. On March 31, 2017, the Partnership closed on its third purchase in the Sanish field, acquiring an additional approximate average 10.5% non-operated working interest in 82 of the Partnership’s then 216 existing producing wells and 150 of the Partnership’s then 253 future development locations in the Sanish Field Assets for approximately $52.4 million. The Partnership has drilled and completed 86 new wells since the beginning of 2018; the Partnership’s estimated share of capital expenditures for the drilling and completion of these 86 wells totaled approximately $120 million. Since October 2023, the Partnership has elected to participate in 13 more wells, of which six (6) were in-process as of December 31, 2023. The Partnership has an approximate 18.5% non-operated working interest in these 13 wells, which are anticipated to be completed in the first half of 2024 at a total estimated cost to the Partnership of approximately $23 million. Many factors outside the Partnership’s control make it difficult to predict the amount and timing of capital expenditures and estimated capital expenditures could be significantly different from amounts actually invested.

Debt Disclosure [Abstract]
Debt Disclosure [Text Block]	Note 4. Debt On May 13, 2021, the Partnership and its wholly-owned subsidiary, as borrowers, entered into a loan agreement (“BF Loan Agreement”) with BancFirst, as administrative agent for the lenders (the “Lender”), which provided for a revolving credit facility (“BF Credit Facility”) with an approved maximum credit amount (“Maximum Credit Amount”) of $60 million, subject to borrowing base restrictions. The Partnership paid an origination fee of 0.50% of the Maximum Credit Amount, or $300,000. Total capitalized loan costs, which were approximately $400,000, were recorded as Other assets on the Partnership’s balance sheets and approximately $24,000 of the deferred loan costs remained unamortized at December 31, 2023. The Partnership also paid an annual fee to the Lender of $30,000, and an unused facility fee of 0.25% on the unused portion of the BF Credit Facility, based on borrowings outstanding during a quarter. The interest rate is equal to the Wall Street Journal Prime Rate plus 0.50%, with a floor of 4.00%. The Partnership was in compliance with its applicable covenants and had no outstanding borrowings on the BF Credit Facility at December 31, 2023, and through the maturity date of March 1, 2024. See Note 9. Subsequent Events for details on the fifth amendment to the BF Loan Agreement, which renews and extends the BF Credit Facility for two years to March 1, 2026. Any further advances under the BF Credit Facility are to be used to fund capital expenditures for the development of the Partnership’s undrilled acreage. Under the terms of the BF Loan Agreement, the Partnership may make voluntary prepayments, in whole or in part, at any time with no penalty. The BF Credit Facility is secured by a mortgage and first lien position on certain of the Partnership’s producing wells. Also, the BF Loan Agreement requires the Partnership to maintain a risk management program to manage the commodity price risk of the Partnership’s future oil and gas production under certain conditions. As amended in August 2022, the Partnership is not required to enter into future hedging transactions as long as the Partnership maintains a BF Credit Facility utilization rate of less than or equal to 20% of the Partnership’s PV-9 (defined as the net present value, discounted at 9% per annum), as calculated by the Lender during the Lender’s scheduled redeterminations. However, the Partnership must hedge at least 50% of its rolling 12-month projected future production if the Partnership’s utilization of the BF Credit Facility is greater than 20% but less than or equal to 30% of PV-9, and at least 50% of its rolling 24-month projected future production if the Partnership’s utilization of the Revolving Credit Facility is greater than 30% of PV-9. Based on the Partnership’s utilization of the BF Credit Facility and Lender’s current calculation of PV-9, the Partnership was not subject to any hedging requirements under the amended BF Loan Agreement as of December 31, 2023. The BF Credit Facility contains prepayment requirements, customary affirmative and negative covenants and events of default. Certain of the financial covenants include: ● A minimum ratio of trailing 12-month EBITDAX to debt service coverage of 1.20 to 1.0 ● A minimum ratio of current assets to current liabilities of 1.00 to 1.00 In addition, the Partnership is permitted to make distributions to its limited partners so long as the Partnership is in compliance with its debt service coverage ratio and no other event of default has occurred. As of December 31, 2022, the outstanding balance on the BF Credit Facility of approximately $22.6 million approximated the fair market value. The Partnership estimated the fair value of its credit facility by discounting the future cash flows of the instrument at estimated market rates consistent with the maturity of a debt obligation with similar credit terms and credit characteristics, which are Level 3 inputs under the fair value hierarchy. Market rates take into consideration general market conditions and maturity.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Note 5. Fair Value of Financial Instruments The Partnership follows authoritative guidance related to fair value measurement and disclosure, which establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement using market participant assumptions at the measurement date. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined as follows: ● Level 1: Quoted prices in active markets for identical assets ● Level 2: Significant other observable inputs – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, either directly or indirectly, for substantially the full term of the financial instrument ● Level 3: Significant unobservable inputs The Partnership’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and the consideration of factors specific to the asset or liability. The Partnership’s policy is to recognize transfers in or out of a fair value hierarchy as of the end of the reporting period for which the event or change in circumstances caused the transfer. The Partnership has consistently applied the valuation techniques discussed above for all periods presented. During the years ended December 31, 2023 and 2022, there were no transfers in or out of Level 1, Level 2, or Level 3 assets and liabilities measured on a recurring basis. As required, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following table sets forth by level within the fair value hierarchy the Partnership’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2022. Fair Value Measurements at December 31, 2022 Quoted Prices in Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Commodity derivatives - current liabilities $ - $ (3,173,965 ) $ - Total $ - $ (3,173,965 ) $ - The Level 2 instruments presented in the table above consist of Partnership’s costless collar commodity derivative instruments. The fair value of the Partnership’s derivative financial instruments at December 31, 2022 was determined based upon future prices, volatility and time to maturity, among other things. Counterparty statements were utilized to determine the value of the commodity derivative instruments and were reviewed and corroborated by the Partnership using various methodologies and significant observable inputs, including quoted market prices in active markets and quotes from third parties, among other things. The Partnership also performed an internal valuation to ensure the reasonableness of third-party quotes. In consideration of counterparty credit risk, the Partnership assessed the possibility of whether the counterparty to the derivative would default by failing to make any contractually-required payments. Additionally, the Partnership considered that the counterparty is of substantial credit quality and had the financial resources and willingness to meet its potential repayment obligations associated with the derivative transactions. See additional detail in Note 6. Risk Management. Fair Value of Other Financial Instruments The carrying value of the Partnership’s cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities reflect these items’ cost, which approximates fair value based on the timing of the anticipated cash flows, current market conditions and short-term maturity of these instruments. In addition, see Note 4. Debt for the fair value discussion on the Partnership’s debt.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Note 6. Risk Management Participation in the oil and gas industry exposes the Partnership to risks associated with potentially volatile changes in energy commodity prices, and therefore, the Partnership’s future earnings are subject to these risks. Therefore, the Partnership periodically utilizes derivative contracts to manage the commodity price risk on the Partnership’s future oil production it will produce and sell and to reduce the effect of volatility in commodity price changes to provide a base level of cash flow from operations. In July 2021, the Partnership began its risk management program required under the BF Loan Agreement (see Note 4. Debt). To meet BF Loan Agreement requirements, the Partnership entered into two-way costless collar derivative contracts for the period from July 2021 to September 2023. Two-way collars are designed to establish a minimum price (floor) and a maximum price (ceiling) for the future production volumes under contract. The Partnership did not pay or receive a premium related to the costless collars into which it entered to remain compliant with the BF Loan Agreement, and the contracts were settled monthly. The Partnership had no outstanding derivative contracts at December 31, 2023, and the Partnership is not currently required to hedge future production under the BF Loan Agreement. As of December 31, 2022, the Partnership’s derivative instruments were in a loss position. The Partnership recognized a total liability of approximately $3.2 million, of which the full balance was recorded as current in Derivative liability on the Partnership’s consolidated balance sheet as of December 31, 2022. The derivative liability as of December 31, 2022 approximated fair value. The Partnership did not designate its derivative instruments as hedges for accounting purposes and did not enter into such instruments for speculative trading purposes. As a result, when derivatives do not qualify or are not designated as a hedge, the changes in the fair value are recognized on the Partnership’s consolidated statements of operations as a gain or loss on derivative instruments. The following table presents the settlement losses of matured derivative instruments and non-cash mark-to-market gains (losses) for the periods presented. Year Ended Year Ended Settlements on matured derivatives $ (1,780,610 ) $ (6,603,660 ) Gain (loss) on mark-to-market of derivatives, net 3,033,037 (668,714 ) Gain (loss) on derivatives, net $ 1,252,427 $ (7,272,374 ) Settlements on matured derivatives above reflect realized losses on derivative contracts which matured during the periods presented, calculated as the difference between the contract price and the market settlement price. The mark-to-market (non-cash, unrealized) gains or losses above represent the change in fair value of derivative instruments which were held at period-end. Unrealized gains or losses do not represent actual settlements or payments made to or from the counterparty. The Partnership’s derivative instruments were covered by an International Swap Dealers Association Master Agreement (“ISDA”) entered into with the counterparty. The ISDA may provide that as a result of certain circumstances, such as cross-defaults, a counterparty may require all outstanding derivative instruments under an ISDA to be settled immediately. The Partnership had netting arrangements with the counterparty that provided for offsetting payables against receivables from separate derivative instruments. The use of derivative instruments involved the risk that the Partnership’s counterparty may have been unable to meet the financial terms of such instruments.

Partners' Capital Notes [Abstract]
Partners' Capital Notes Disclosure [Text Block]	Note 7. Capital Contribution and Partners Equity At inception, the General Partner and organizational limited partner made initial capital contributions totaling $1,000 to the Partnership. Upon closing of the minimum offering the organizational limited partner withdrew its initial capital contribution of $990, the General Partner received Incentive Distribution Rights (defined below), and was reimbursed for its documented third-party out-of-pocket expenses incurred in organizing the Partnership and offering the common units. The Partnership completed its best-efforts offering of common units on April 24, 2017. As of the conclusion of the offering on April 24, 2017, the Partnership had completed the sale of approximately 19.0 million common units for total gross proceeds of $374.2 million and proceeds net of offerings costs of $349.6 million. Under the agreement with the Dealer Manager, the Dealer Manager received a total of 6% in selling commissions and a marketing expense allowance based on gross proceeds of the common units sold. The Dealer Manager will also be paid a contingent incentive fee, which is a cash payment of up to an amount equal to 4% of gross proceeds of the common units sold based on the performance of the Partnership. Based on the common units sold in the best-efforts offering, the total contingent fee is approximately $15.0 million. Prior to “Payout,” which is defined below, all of the distributions made by the Partnership, if any, will be paid to the holders of common units. Accordingly, the Partnership will not make any distributions or record any liability with respect to the Incentive Distribution Rights (owned by the General Partner), the Class B units or the contingent, incentive payments to the Dealer Manager until an event that triggers Payout occurs. The Partnership Agreement provides that Payout occurs on the day when the aggregate amount distributed with respect to each of the common units equals $20.00 plus the Payout Accrual. The Partnership Agreement defines “Payout Accrual” as 7% per annum simple interest accrued monthly until paid on the Net Investment Amount outstanding from time to time. The Partnership Agreement defines Net Investment Amount initially as $20.00 per common unit, regardless of the amount paid for the common unit. If at any time the Partnership distributes to holders of common units more than the Payout Accrual, the amount the Partnership distributes in excess of the Payout Accrual will reduce the Net Investment Amount. All distributions made by the Partnership after Payout, which may include all or a portion of the proceeds of the sale of all or substantially all of the Partnership’s assets, will be made as follows: ● First, (i) to the Record Holders of the Incentive Distribution Rights, 35%; (ii) to the Record Holders of the Outstanding Class B units, pro rata based on the number of Class B units owned, 35% multiplied by a fraction, the numerator of which is the number of Class B units outstanding and the denominator of which is 100,000 (currently, there are 62,500 Class B units outstanding; therefore, Class B units could receive 21.875%); (iii) to the Dealer Manager, as the Dealer Manager contingent incentive fee paid under the Dealer Manager Agreement, 30%, and (iv) the remaining amount, if any (currently 13.125%), to the Record Holders of outstanding common units, pro rata based on their percentage interest until such time as the Dealer Manager receives the full amount of the Dealer Manager contingent incentive fee under the Dealer Manager Agreement; ● Thereafter, (i) to the Record Holders of the Incentive Distribution Rights, 35%; (ii) to the Record Holders of the Outstanding Class B units, pro rata based on the number of Class B units owned, 35% multiplied by a fraction, the numerator of which is the number of Class B units outstanding and the denominator of which is 100,000 (currently, there are 62,500 Class B units outstanding; therefore, Class B units could receive 21.875%); (iii) the remaining amount to the Record Holders of outstanding common units, pro rata based on their percentage interest (currently 43.125%). All items of income, gain, loss and deduction will be allocated to each Partner’s capital account in a manner generally consistent with the distribution procedures outlined above. For the year ended December 31, 2023, the Partnership paid distributions of $1.425753 per common unit, or $27.1 million. In addition, the Partnership declared a monthly cash distribution to its holders of common units of $0.12 per common unit for the month of December 2023. The declared distribution of approximately $2.3 million, which is included in Accounts payable and accrued expenses on the Partnership’s balance sheet as of December 31, 2023, was paid on January 4, 2024 to the common unit holders on record as of December 31, 2023. For the year ended December 31, 2022, the Partnership paid distributions of $1.258082 per common unit, or $23.9 million. The Partnership accumulates unpaid distributions based on an annualized return of seven percent (7%), and all accumulated unpaid distributions are required to be paid before final Payout occurs, as defined above. As of December 31, 2023, the unpaid Payout Accrual, for the period from March 2020 through November 2021, totaled $2.374841 per common unit, or approximately $45 million.

Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	Note 8. Related Parties The members of the General Partner are affiliates of Glade M. Knight, Chairman and Chief Executive Officer, and David S. McKenney, Chief Financial Officer. Mr. Knight and Mr. McKenney are also the Chief Executive Officer and Chief Financial Officer of Energy Resources 12 GP, LLC, the general partner of Energy Resources 12, L.P. (“ER12”), a limited partnership that also invests in producing and non-producing oil and natural gas properties on-shore in the United States. The Partnership has, and is expected to continue to engage in, significant transactions with related parties. These transactions cannot be construed to be at arm’s length and the results of the Partnership’s operations may be different than if conducted with non-related parties. The General Partner’s Board of Directors oversees and reviews the Partnership’s related party relationships and is required to approve any significant modifications to any existing related party transactions, as well as any new significant related party transactions. For the years ended December 31, 2023 and 2022, approximately $291,000 and $165,000 of general and administrative costs were incurred by a member of the General Partner and have been or will be reimbursed by the Partnership. At December 31, 2023 and 2022, approximately $119,000 and $57,000, respectively, was due to a member of the General Partner; these costs are included in Accounts payable and accrued expenses in the consolidated balance sheets. On December 1, 2020, the Partnership entered into an Administrative Services Agreement (the “ASA”) with Regional Energy Investors, L.P. d/b/a Regional Energy Management (the “Administrator”) and ER12, whereby the Administrator was to provide administrative, operating and professional services necessary and useful to the Partnership. The Administrator also was to assist the General Partner with the day-to-day operations of the Partnership. The Administrator is owned by entities that are controlled by Anthony F. Keating, III and Michael J. Mallick, the now former Co-Chief Operating Officers of the General Partner. The ASA became effective January 1, 2021. On April 5, 2023, the Partnership and ER12 entered into an agreement (the “Agreement”) with Messrs. Knight, McKenney, Keating and Mallick, and various affiliates of each, including the Administrator. Pursuant to the Agreement, the ASA was terminated effective immediately, subject to a 60-day transition period to transition the services being provided by the Administrator to Partnership and ER12 management. Prior to termination, all Administrator costs and expenses subject to the ASA were accumulated (based on actual costs incurred with no mark-up or profit to the Administrator) and approved by the Partnership prior to reimbursement. Costs and expenses reimbursed under the ASA included, but were not limited to, employee wages and benefits, rent for office space and network and information technology support. Other expenses, such as business travel costs and accounting, legal or banking services, were not incurred by the Administrator on behalf of the Partnership without prior express written consent of the Partnership. Costs and expenses attributable to the services performed by the Administrator under the ASA have been reimbursed by the Partnership. For the years ended December 31, 2023 and 2022, approximately $165,000 and $634,000 of costs and expenses subject to the ASA were reimbursed by the Partnership to the Administrator. Also pursuant to the Agreement, the affiliates of Messrs. Keating and Mallick sold (i) all interests in the General Partner; (ii) all common unit interests in the Partnership; (iii) all Class B Unit interests in the Partnership; and (iv) their Class B Unit interests in ER12’s General Partner to an affiliate of Mr. Knight and withdrew as members of General Partner and ER12’s General Partner. Each of Messrs. Keating and Mallick also resigned their positions as director and as Co-Chief Operating Officer of the General Partner. Additionally, Clifford J. Merritt resigned as President of the General Partner. Prior to the execution of the Agreement, the Administrator assisted Energy Resources 12 GP, LLC, the general partner of ER12 (“ER12’s General Partner”), with the day-to-day operations of ER12. ER12 currently pays ER12’s General Partner an annual management fee of 0.5% of the total gross equity proceeds raised by ER12 in its best-efforts offering. Under the ASA, ER12’s General Partner paid one-half of its annual management fee to the Administrator in exchange for the services to be provided under the ASA. This fee is only applicable to ER12 and does not apply to the Partnership. E11 Incentive Holdings, LLC (“Incentive Holdings”) was the owner of all Class B units outstanding (62,500) as of March 31, 2017. During the second quarter of 2017, Incentive Holdings transferred substantially all of its assets: (1) on April 5, 2017, Incentive Holdings transferred 18,125 of the 62,500 Class B units to E11 Incentive Carry Vehicle, LLC, an affiliate of Incentive Holdings, for de minimis consideration; and (2) on April 6, 2017, the remaining 44,375 Class B units were acquired by Regional Energy Incentives, LP in exchange for approximately $98,000. Regional Energy Incentives, LP was owned by entities controlled by Messrs. Keating, Mallick and McKenney. In conjunction with the Agreement discussed above, as of April 5, 2023, affiliates of Messrs. Knight and McKenney now own the 44,375 Class B units previously owned by Regional Energy Incentives, LP. E11 Incentive Carry Vehicle, LLC still owns the remaining 18,125 outstanding Class B units. The Class B units entitle the holder to certain distribution rights after Payout, as described in Note 7. Capital Contribution and Partners’ Equity.

Subsequent Events [Abstract]
Subsequent Events [Text Block]	Note 9. Subsequent Events In January 2024, the General Partner of the Partnership declared a monthly cash distribution to its holders of common units of $0.11 per outstanding common unit for the month of January 2024. In addition, the General Partner declared a special distribution of $0.05 per common unit that reduced the accumulated unpaid distribution total described above. The distributions, which together total approximately $3.0 million, were paid on February 5, 2024 to common unit holders on record as of January 31, 2024. In February 2024, the Partnership declared a monthly cash distribution to its holders of common units of $0.12 per outstanding common unit for the month of February 2024. The distribution of approximately $2.3 million was paid on March 5, 2024 to common unit holders on record as of February 29, 2024. On February 27, 2024, the Partnership and its Lender entered into an amendment (“Fifth Amendment”) to the BF Loan Agreement, effective March 1, 2024 (“Effective Date”), that renewed and extended the BF Credit Facility for two additional years to March 1, 2026 (“Revised Maturity Date”). Key terms and conditions of the Fifth Amendment include: ● As of the Effective Date, the borrowing base of the BF Credit Facility is $20,000,000. ● As amended, the Partnership remains subject to a semiannual redetermination of its borrowing base, but the Partnership is only required to perform an annual analysis of its proven oil and natural gas reserves as of January 1 of each year. ● The Partnership paid a loan fee to the Lender associated with the Fifth Amendment of $100,000. ● Previously under the BF Loan Agreement, the Partnership was required to pay a $30,000 annual administrative fee to the Lender. Because BancFirst will be the only Lender effective March 1, 2024, the administrative fee has been waived through the Revised Maturity Date. The Partnership remains permitted to make distributions to its limited partners so long as the Partnership is in compliance with its debt service coverage ratio and no other event of default has occurred. Further, the Partnership is currently not subject to any hedging requirements under the BF Loan Agreement, as previously amended. All other terms and conditions of the BF Loan Agreement and its subsequent amendments remain in effect.

Supplementary Information on Oil, Natural Gas and Natural Gas Liquid Reserves (Unaudited) Aggregate Capitalized Costs The aggregate amount of capitalized costs of oil, natural gas and NGL properties and related accumulated depreciation, depletion and amortization as of December 31, 2023 and 2022 is as follows: 2023 2022 Producing properties $ 311,292,892 $ 296,175,283 Non-producing 173,414,110 176,389,110 484,707,002 472,564,393 Accumulated depreciation, depletion and amortization (146,161,010 ) (119,045,055 ) Net capitalized costs $ 338,545,992 $ 353,519,338 Costs Incurred For the years ended December 31, 2023 and 2022, the Partnership incurred the following costs in oil and natural gas producing activities: 2023 2022 Development costs $ 12,142,610 $ 49,381,239 Estimated Quantities of Proved Oil, NGL and Natural Gas Reserves The following unaudited information regarding the Partnership’s oil, natural gas and NGL reserves is presented pursuant to disclosures required by the SEC and the FASB. Proved oil and natural gas reserves are those quantities of oil, natural gas and NGLs which, by analysis of geosciences 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 – prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions. The project to extract the hydrocarbons must have commenced, or the operator must be reasonably certain that it will commence the project within a reasonable time. The area of the reservoir considered as proved includes: (i) the area identified by drilling and limited by fluid contacts, if any, and (ii) adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or natural gas on the basis of available geoscience and engineering data. In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons as seen in a well penetration unless geoscience, engineering or performance data and reliable technology establishes a lower contact with reasonable certainty. Where direct observation from well penetrations has defined a highest known oil elevation and the potential exists for an associated natural gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering or performance data and reliable technology establish the higher contact with reasonable certainty. Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when: (i) successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and (ii) the project has been approved for development by all necessary parties and entities, including governmental entities. The independent consulting petroleum engineering firm of Pinnacle Energy of Oklahoma City, OK, prepared estimates of the Partnership’s oil, natural gas and NGL reserves as of December 31, 2023, 2022 and 2021. The Partnership’s net proved oil, NGL and natural gas reserves, all of which are located in the contiguous United States, as of December 31, 2023, 2022 and 2021, have been estimated by the Partnership’s independent consulting petroleum engineering firm. Estimates of reserves were prepared by the use of appropriate geologic, petroleum engineering and evaluation principles and techniques that are in accordance with SEC rules and regulations along with practices generally recognized by the petroleum industry as presented in the publication of the Society of Petroleum Engineers entitled “Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (Revision as of February 19, 2007).” The method or combination of methods used in the analysis of each reservoir was tempered by experience with similar reservoirs, stage of development, quality and completeness of basic data and production history. For depletion-type reservoirs or those whose performance disclosed a reliable decline in producing-rate trends or other diagnostic characteristics, reserves were estimated by the application of appropriate decline curves or other performance relationships. In the analyses of production-decline curves, reserves were estimated only to the limits of economic production or to the limit of the production licenses as appropriate. Accordingly, these estimates should be expected to change, and such changes could be material and occur in the near term as future information becomes available. “Revisions of previous estimates” in the table below represent changes in previous reserve estimates, either upward or downward, resulting from a change in economic factors, such as commodity prices, operating costs or development costs, or resulting from information obtained from the Partnership’s production history. The rollforward of net quantities of proved developed and undeveloped oil, natural gas and NGL reserves are summarized as follows: Proved Reserves Oil Natural Gas NGLs (Bbls) (Mcf) (Bbls) Total (BOE) December 31, 2021 16,100,697 20,900,153 3,006,631 22,590,687 Acquisition - - - - Extensions, discoveries and other additions (1) 1,266,835 1,125,029 160,090 1,614,430 Revisions of previous estimates (2) 4,719,015 3,782,400 508,067 5,857,482 Production (1,054,619 ) (1,329,995 ) (190,503 ) (1,466,788 ) December 31, 2022 21,031,928 24,477,587 3,484,285 28,595,811 Acquisition - - - - Extensions, discoveries and other additions (3) 479,763 431,226 67,009 618,643 Revisions of previous estimates (4) (6,082,609 ) (4,557,429 ) (353,416 ) (7,195,597 ) Production (1,128,242 ) (1,642,775 ) (265,002 ) (1,667,039 ) December 31, 2023 14,300,840 18,708,609 2,932,876 20,351,818 (1) In 2022, extensions, discoveries and other additions of 1,614 MBOE were primarily attributable to successful drilling by the Partnership’s primary operator of the Sanish Field Assets. (2) Revisions to previous estimates increased proved reserves by a net amount of 5,857 MBOE. These revisions result from 8,177 MBOE of upward adjustments attributable to changes in the future drill schedule and 164 MBOE of upward adjustments attributable caused by higher oil, natural gas and NGL prices when comparing the Partnership’s reserve estimates at December 31, 2022 to December 31, 2021, offset by 2,484 MBOE of downward adjustments attributable to well performance when comparing the Partnership’s reserve estimates at December 31, 2022 to December 31, 2021. (3) In 2023, extensions, discoveries and other additions of 619 MBOE were primarily attributable to successful drilling by the Partnership’s primary operator of the Sanish Field Assets. (4) Revisions to previous estimates decreased proved reserves by a net amount of 7,196 MBOE. These revisions result from 5,522 MBOE of downward adjustments attributable to changes in the future drill schedule and recovery projections, 1,373 MBOE of downward adjustments attributable to well performance, and 301 MBOE of downward adjustments caused by lower oil, natural gas and NGL prices when comparing the Partnership’s reserve estimates at December 31, 2023 to December 31, 2022. In accordance with SEC Regulation S-X, Rule 4-10, as amended, the Partnership uses the 12-month average price calculated as the unweighted arithmetic average of the spot price on the first day of each month within the 12-month period prior to the end of the reporting period. The average realized oil, natural gas and NGL prices, including the effect of price differential adjustments, used in computing the Partnership’s reserves as of December 31, 2023 were $78.25 per barrel of oil, $2.51 per MMcf of natural gas and $13.30 per barrel of NGL. The average realized oil, natural gas and NGL prices, including the effect of price differential adjustments, used in computing the Partnership’s reserves as of December 31, 2022 were $90.51 per barrel of oil, $6.75 per MMcf of natural gas and $40.28 per barrel of NGL. Net quantities of proved developed and proved undeveloped reserves at December 31, 2023, 2022 and 2021 are summarized in the table below. Oil Natural Gas NGLs (Bbls) (Mcf) (Bbls) Total (BOE) Proved developed reserves: December 31, 2021 11,197,370 15,350,678 2,207,738 15,963,554 December 31, 2022 12,959,918 16,547,639 2,355,866 18,073,724 December 31, 2023 10,199,826 14,882,637 2,338,351 15,018,617 Proved undeveloped reserves: December 31, 2021 4,903,327 5,549,475 798,893 6,627,133 December 31, 2022 8,072,010 7,929,948 1,128,419 10,522,087 December 31, 2023 4,101,014 3,825,972 594,525 5,333,201 The following details the changes in proved undeveloped reserves (PUD) for 2022 and 2023: BOE Proved undeveloped reserves, December 31, 2021 6,627,133 Revisions of previous estimates (1) 7,803,541 Extensions, discoveries and other additions (2) 1,614,430 Conversion to proved developed reserves (3) (5,523,017 ) Proved undeveloped reserves acquired - Proved undeveloped reserves, December 31, 2022 10,522,087 Revisions of previous estimates (4) (5,360,513 ) Extensions, discoveries and other additions (5) 618,643 Conversion to proved developed reserves (6) (447,016 ) Proved undeveloped reserves acquired - Proved undeveloped reserves, December 31, 2023 5,333,201 (1) The annual review of the PUDs resulted in a positive revision of approximately 7,804 MBOE. This revision was the result of 8,177 MBOE of upward adjustments attributable to changes in the future drill schedule and offset by 373 MBOE of downward adjustments attributable to changes in natural gas shrink and NGL yield when comparing the Partnership’s reserves at December 31, 2022 to December 31, 2021. (2) In 2022, extensions, discoveries and other additions of 1,614 MBOE were primarily attributable to successful drilling by the Partnership’s primary operator of the Sanish Field Assets. (3) The Partnership completed 27 new wells during 2022; therefore, the Partnership converted these 27 wells to proved developed reserves during 2022, which resulted in a downward adjustment to PUDs of 5,523 MBOE. (4) The annual review of the PUDs resulted in a negative revision of approximately 5,361 MBOE. This revision was the result of 5,522 MBOE of downward adjustments attributable to changes in the future drill schedule and recovery projections, offset by 161 MBOE of upward adjustments attributable to changes in natural gas shrink and NGL yield when comparing the Partnership’s reserves at December 31, 2023 to December 31, 2022. (5) In 2023, extensions, discoveries and other additions of 619 MBOE were primarily attributable to successful drilling by the Partnership’s primary operator of the Sanish Field Assets. (6) The Partnership completed 6 new wells during 2023; therefore, the Partnership converted these 6 wells to proved developed reserves during 2023, which resulted in a downward adjustment to PUDs of 447 MBOE. Based upon current information from its operators, the Partnership anticipates all current PUD locations will be drilled and converted to PDP within five years of the date they were added. PUD locations and associated reserves which are no longer projected to be drilled within five years from the date they were first booked as proved undeveloped reserves have been removed as revisions at the time that determination was made. Standardized Measure of Discounted Future Net Cash Flows Accounting standards prescribe guidelines for computing a standardized measure of future net cash flows and changes therein relating to estimated proved reserves. The Partnership has followed these guidelines, which are briefly discussed below. Future cash inflows and future production and development costs are determined by applying the trailing unweighted 12-month arithmetic average of the first-day-of-the-month individual product prices and year-end costs to the estimated quantities of oil, natural gas and NGL to be produced. Actual future prices and costs may be materially higher or lower than the unweighted 12-month arithmetic average of the first-day-of-the-month individual product prices and year-end costs used. For each year, estimates are made of quantities of proved reserves and the future periods during which they are expected to be produced based on continuation of the economic conditions applied for such year. The resulting future net cash flows are reduced to present value amounts by applying a 10% annual discount factor. The assumptions used to compute the standardized measure are those prescribed by the FASB and, as such, do not necessarily reflect the Partnership’s expectations of actual revenue to be derived from those reserves nor their present worth. The limitations inherent in the reserve quantity estimation process, as discussed previously, are equally applicable to the standardized measure computations since these estimates affect the valuation process. 2023 2022 Future cash inflows $ 1,205,028,864 $ 2,209,148,928 Future production costs (493,017,336 ) (586,350,144 ) Future development costs (98,927,304 ) (110,237,400 ) Future net cash flows 613,084,224 1,512,561,384 10% annual discount (326,905,824 ) (864,351,720 ) Standardized measure of discounted future net cash flows $ 286,178,400 $ 648,209,664 Changes in the standardized measure of discounted future net cash flows are as follows: 2023 2022 Standardized measure at beginning of period $ 648,209,664 $ 308,184,640 Changes resulting from: Acquisition of reserves - - Extensions, discoveries and other additions 6,992,407 49,126,990 Sales of oil, natural gas and NGLs, net of production costs (65,339,727 ) (85,215,526 ) Net changes in prices and production costs (208,831,086 ) 240,520,851 Development costs incurred during the period 12,142,610 49,381,239 Revisions to previous estimates (171,073,805 ) 150,980,130 Accretion of discount 64,910,851 30,861,199 Change in estimated future development costs (832,514 ) (95,629,859 ) Standardized measure of discounted future net cash flows $ 286,178,400 $ 648,209,664

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying consolidated financial statements of the Partnership have been prepared in accordance with United States generally accepted accounting principles (“US GAAP”). The consolidated financial statements include the accounts of the Partnership and its subsidiaries.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash, Cash Equivalents and Restricted Cash and Cash Equivalents Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less. The fair market value of cash and cash equivalents approximates their carrying value. Cash balances may at times exceed federal depository insurance limits.
Oil and Gas Properties Policy [Policy Text Block]	Property and Depreciation, Depletion and Amortization The Partnership accounts for its oil and natural gas properties using the successful efforts method of accounting. Under this method, costs of productive exploratory wells, development dry holes and productive wells and undeveloped leases are capitalized. Oil and natural gas lease acquisition costs are also capitalized. Exploration costs, including personnel costs, certain geological and geophysical expenses and delay rentals for oil and natural gas leases, are charged to expense during the period the costs are incurred. Exploratory drilling costs are initially capitalized but charged to expense if and when the well is determined not to have found reserves in commercial quantities. The capitalized costs of oil and natural gas properties are depleted using the unit-of-production method on a field basis based on estimated proved developed and/or undeveloped oil, natural gas and NGL reserves. No gains or losses are recognized upon the disposition of proved oil and natural gas properties except in transactions such as the significant disposition of an amortizable base that significantly affects the unit–of–production amortization rate. Sales proceeds are credited to the carrying value of the properties. The application of the successful efforts method of accounting requires managerial judgment to determine the proper classification of wells designated as development or exploratory which will ultimately determine the proper accounting treatment of the costs incurred. The results from a drilling operation can take considerable time to analyze and the determination that commercial reserves have been discovered requires both judgment and industry experience. Wells may be completed that are assumed to be productive and actually deliver oil, natural gas and natural gas liquids in quantities insufficient to be economic, which may result in the abandonment of the wells at a later date. Wells are drilled that have targeted geologic structures that are both developmental and exploratory in nature, and an allocation of costs is required to properly account for the results. Delineation seismic incurred to select development locations within an oil and natural gas field is typically considered a development cost and capitalized, but often these seismic programs extend beyond the reserve area considered proved and management must estimate the portion of the seismic costs to expense. The evaluation of oil and natural gas leasehold acquisition costs requires managerial judgment to estimate the fair value of these costs with reference to drilling activity in a given area. Drilling activities in an area by other companies may also effectively condemn leasehold positions.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment The Partnership assesses its proved oil and natural gas properties for possible impairment whenever events or circumstances indicate that the recorded carrying value of the properties may not be recoverable. Such events include a projection of future reserves that will be produced from a field, the timing of this future production, future costs to produce the oil, natural gas and natural gas liquids and future inflation levels. If the carrying amount of the properties exceeds the sum of the estimated undiscounted future net cash flows, the Partnership recognizes an impairment expense equal to the difference between the carrying value and the fair value of the properties, which is estimated to be the expected present value of the future net cash flows. Estimated future net cash flows are based on existing reserves, forecasted production and cost information and management’s outlook of future commodity prices. Where probable and possible reserves exist, an appropriately risk adjusted amount of these reserves is included in the impairment evaluation. The underlying commodity prices used in the determination of our estimated future net cash flows are based on NYMEX forward strip prices at the end of the period, adjusted by field or area for estimated location and quality differentials, as well as other trends and factors that management believes will impact realizable prices. Future operating costs estimates are also developed based on a review of actual costs by field or area. Downward revisions in estimates of reserve quantities or expectations of falling commodity prices or rising operating costs could result in a reduction in undiscounted future cash flows and could indicate a property impairment.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates Preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts and disclosures reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Of these estimates and assumptions, management considers the estimation of oil, natural gas and NGL reserves to be the most significant. These estimates affect the unaudited standardized measure disclosures, as well as depreciation, depletion and amortization (“DD&A”) and impairment calculations. On an annual basis, the Partnership’s independent consulting petroleum engineer, with assistance from the Partnership, prepares estimates of oil, natural gas and NGL reserves based on available geologic and seismic data, reservoir pressure data, core analysis reports, well logs, analogous reservoir performance history, production data and other available sources of engineering, geological and geophysical information. For DD&A purposes, and as required by the guidelines and definitions established by the Securities and Exchange Commission (“SEC”), the reserve estimates were based on average individual product prices during the 12-month period prior to December 31, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period excluding escalations based upon future conditions. For impairment purposes, projected NYMEX forward strip prices for oil, natural gas and NGL as estimated by management are used. Oil, natural gas and NGL prices are volatile and largely affected by worldwide production and consumption and are outside the control of management. Projected future oil, natural gas and NGL pricing assumptions are used by management to prepare estimates of oil, natural gas and NGL reserves used in formulating management’s overall operating decisions. The Partnership does not operate its oil and natural gas properties and, therefore, receives actual oil, natural gas and NGL sales volumes and prices (in the normal course of business) more than a month later than the information is available to the operators of the wells. This being the case, the most current available production data is gathered from the appropriate operators, and oil, natural gas and NGL index prices local to each well are used to estimate the accrual of revenue on these wells. The oil, natural gas and NGL sales revenue accrual can be impacted by many variables including rapid production decline rates, production curtailments by operators, the shut-in of wells with mechanical problems and rapidly changing market prices for oil, natural gas and NGLs. These variables could lead to an over or under accrual of oil, natural gas and NGL sales at the end of any particular quarter. However, the Partnership adjusts the estimated accruals of revenue to actual production in the period actual production is determined.
Revenue [Policy Text Block]	Revenue Recognition The Partnership is bound by a joint operating agreement with the operator of each of its producing wells. Under the joint operating agreement, the Partnership’s proportionate share of production is marketed at the discretion of the operators. The Partnership typically satisfies its performance obligations upon transfer of control of its products and records the related revenue in the month production is delivered to the purchaser. As the Partnership does not operate its properties, it receives actual oil, natural gas, and NGL sales volumes and prices, net of costs incurred by the operators, two to three months after the date production is delivered by the operator. At the end of each month when the performance obligation is satisfied, the variable consideration can be reasonably estimated and amounts due from the Partnership’s operators are accrued in Oil, natural gas and natural gas liquids revenue receivable in the consolidated balance sheets. Variances between the Partnership’s estimated revenue and actual payments are recorded in the month the payment is received; differences have been and are insignificant. As a result, the variable consideration is not constrained. The Partnership has elected to utilize the practical expedient in ASC 606 that states the Partnership is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Each delivery of product represents a separate performance obligation; therefore, future volumes are wholly unsatisfied, and disclosure of the transaction price allocated to remaining performance obligations is not required. Virtually all of the Partnership’s contracts’ pricing provisions are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or transmission line, quality of oil, natural gas and natural gas liquids and prevailing supply and demand conditions, so that prices fluctuate to remain competitive with other available suppliers.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Accounts Receivable and Concentration of Credit Risk For the year ended December 31, 2023, the Partnership’s oil, natural gas and NGL sales were through two operators. Substantially all the Partnership’s accounts receivable is due from Chord, the largest operator of the Partnership’s oil and natural gas properties in North Dakota (operators have accounts receivable from purchasers of oil, natural gas and NGLs). Oil, natural gas and NGL sales receivables are generally unsecured. This industry and location concentration has the potential to impact the Partnership’s overall exposure to credit risk, in that the purchasers of the Partnership’s oil, natural gas and NGLs and the operators of the properties in which the Partnership has an interest may be similarly affected by changes in economic, industry or other conditions. At December 31, 2023, the Partnership did not reserve for bad debt expense, as all amounts are deemed collectible. Chord is the current operator of 99% of the Partnership’s producing properties. All oil and natural gas producing activities of the Partnership are in North Dakota and represent substantially all of the business activities of the Partnership.
Asset Retirement Obligation [Policy Text Block]	Asset Retirement Obligation The Partnership has significant obligations to remove tangible equipment and facilities and restore land at the end of oil and natural gas production operations. The removal and restoration obligations are primarily associated with site reclamation, dismantling facilities and plugging and abandoning wells. 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 contracts and regulations often have vague descriptions of what constitutes removal. Asset removal technologies and costs are constantly changing, as are regulatory, political, environmental, safety and public relations considerations. The Partnership records an asset retirement obligation (“ARO”) and capitalizes the asset retirement cost in oil and natural gas properties in the period in which the retirement obligation is incurred based upon the fair value of an obligation to perform site reclamation, dismantle facilities or plug and abandon wells. After recording these amounts, the ARO is accreted to its future estimated value using an assumed cost of funds and the additional capitalized costs are depreciated on a unit-of-production basis. 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 of these assumptions impact the present value of the existing asset retirement obligation, a corresponding adjustment is made to the oil and natural gas property balance. The following table shows the activity for the years ended December 31, 2023 and 2022, relating to the Partnership’s asset retirement obligations: Balance as of December 31, 2021 $ 1,791,341 Well additions 95,480 Accretion 97,588 Revisions in estimated cash flows (17,671 ) Balance as of December 31, 2022 1,966,738 Well additions 4,748 Accretion 107,855 Revisions in estimated cash flows (18,821 ) Balance as of December 31, 2023 $ 2,060,520
Income Tax, Policy [Policy Text Block]	Income Tax The Partnership is taxed as a partnership for federal and state income tax purposes. Typically, the Partnership has not recorded a provision for income taxes since the liability for such taxes is that of each of the partners rather than the Partnership. In mid-2022, the Partnership was contacted by the state of North Dakota, which asserted that the Partnership has an obligation to make tax payments on behalf of certain non-resident partners. The Partnership reached a resolution with the state of North Dakota that entailed the Partnership making a payment of taxes on behalf of certain non-resident limited partners to the state for the tax years of 2021 and 2022. The Partnership made a payment of approximately $243,000 (approximately $0.013 per common unit) in May 2023 that settled the 2021 tax year. The Partnership recorded an estimate at December 31, 2022 of approximately $315,000 for the 2022 tax year. In addition, the Partnership recorded an estimated at December 31, 2023 of approximately $1.0 million for the 2023 tax year. Settlements for the 2022 and 2023 tax years are expected during 2024. The Partnership’s income tax returns are subject to examination by the federal and state taxing authorities, and changes, if any, could adjust the individual income tax of the partners. The Partnership has evaluated whether any material tax position taken will more likely than not be sustained upon examination by the appropriate taxing authority and believes that all such material tax positions taken are supportable by existing laws and related interpretations.
Environmental Costs, Policy [Policy Text Block]	Environmental Costs As the Partnership is directly involved in the extraction and use of natural resources, it is subject to various federal, state and local provisions regarding environmental and ecological matters. Compliance with these laws may necessitate significant capital outlays. The Partnership does not believe the existence of current environmental laws or interpretations thereof will materially hinder or adversely affect the Partnership’s business operations; however, there can be no assurances of future effects on the Partnership of new laws or interpretations thereof. Since the Partnership does not operate any wells where it owns an interest, actual compliance with environmental laws is controlled by the well operators, with the Partnership being responsible for its proportionate share of the costs involved. Environmental liabilities are recognized when it is probable that a loss has been incurred and the amount of that loss is reasonably estimable. Environmental liabilities, when accrued, are based upon estimates of expected future costs. At December 31, 2023 and 2022, there were no such costs accrued.
Earnings Per Share, Policy [Policy Text Block]	Net Income Per Common Unit Basic net income per common unit is computed as net income divided by the weighted average number of common units outstanding during the period. Diluted net income per unit is calculated after giving effect to all potential common units that were dilutive and outstanding for the period. There were no common units with a dilutive effect for the years ended December 31, 2023 and 2022. As a result, basic and diluted outstanding common units were the same. The Class B Units and Incentive Distribution Rights are not included in net income per common unit until such time that it is probable Payout (as discussed in Note 7) would occur.

(2) Revisions to previous estimates increased proved reserves by a net amount of 5,857 MBOE. These revisions result from 8,177 MBOE of upward adjustments attributable to changes in the future drill schedule and 164 MBOE of upward adjustments attributable caused by higher oil, natural gas and NGL prices when comparing the Partnership’s reserve estimates at December 31, 2022 to December 31, 2021, offset by 2,484 MBOE of downward adjustments attributable to well performance when comparing the Partnership’s reserve estimates at December 31, 2022 to December 31, 2021. (3) In 2023, extensions, discoveries and other additions of 619 MBOE were primarily attributable to successful drilling by the Partnership’s primary operator of the Sanish Field Assets.

This revision was the result of 8,177 MBOE of upward adjustments attributable to changes in the future drill schedule and offset by 373 MBOE of downward adjustments attributable to changes in natural gas shrink and NGL yield when comparing the Partnership’s reserves at December 31, 2022 to December 31, 2021. (2) In 2022, extensions, discoveries and other additions of 1,614 MBOE were primarily attributable to successful drilling by the Partnership’s primary operator of the Sanish Field Assets. (3) The Partnership completed 27 new wells during 2022; therefore, the Partnership converted these 27 wells to proved developed reserves during 2022, which resulted in a downward adjustment to PUDs of 5,523 MBOE. (4) The annual review of the PUDs resulted in a negative revision of approximately 5,361 MBOE. This revision was the result of 5,522 MBOE of downward adjustments attributable to changes in the future drill schedule and recovery projections, offset by 161 MBOE of upward adjustments attributable to changes in natural gas shrink and NGL yield when comparing the Partnership’s reserves at December 31, 2023 to December 31, 2022. (5) In 2023, extensions, discoveries and other additions of 619 MBOE were primarily attributable to successful drilling by the Partnership’s primary operator of the Sanish Field Assets. (6) The Partnership completed 6 new wells during 2023; therefore, the Partnership converted these 6 wells to proved developed reserves during 2023, which resulted in a downward adjustment to PUDs of 447 MBOE.
Standardized Measure of Discounted Future Cash Flows Relating to Proved Reserves Disclosure [Table Text Block]	The resulting future net cash flows are reduced to present value amounts by applying a 10% annual discount factor. The assumptions used to compute the standardized measure are those prescribed by the FASB and, as such, do not necessarily reflect the Partnership’s expectations of actual revenue to be derived from those reserves nor their present worth. The limitations inherent in the reserve quantity estimation process, as discussed previously, are equally applicable to the standardized measure computations since these estimates affect the valuation process. 2023 2022 Future cash inflows $ 1,205,028,864 $ 2,209,148,928 Future production costs (493,017,336 ) (586,350,144 ) Future development costs (98,927,304 ) (110,237,400 ) Future net cash flows 613,084,224 1,512,561,384 10% annual discount (326,905,824 ) (864,351,720 ) Standardized measure of discounted future net cash flows $ 286,178,400 $ 648,209,664

Key Provisions of Operating or Partnership Agreement, Description				The Partnership Agreement provides that Payout occurs on the day when the aggregate amount distributed with respect to each of the common units equals $20.00 plus the Payout Accrual. The Partnership Agreement defines “Payout Accrual” as 7% per annum simple interest accrued monthly until paid on the Net Investment Amount outstanding from time to time. The Partnership Agreement defines Net Investment Amount initially as $20.00 per common unit, regardless of the amount paid for the common unit. If at any time the Partnership distributes to holders of common units more than the Payout Accrual, the amount the Partnership distributes in excess of the Payout Accrual will reduce the Net Investment Amount.All distributions made by the Partnership after Payout, which may include all or a portion of the proceeds of the sale of all or substantially all of the Partnership’s assets, will be made as follows: ● First, (i) to the Record Holders of the Incentive Distribution Rights, 35%; (ii) to the Record Holders of the Outstanding Class B units, pro rata based on the number of Class B units owned, 35% multiplied by a fraction, the numerator of which is the number of Class B units outstanding and the denominator of which is 100,000 (currently, there are 62,500 Class B units outstanding; therefore, Class B units could receive 21.875%); (iii) to the Dealer Manager, as the Dealer Manager contingent incentive fee paid under the Dealer Manager Agreement, 30%, and (iv) the remaining amount, if any (currently 13.125%), to the Record Holders of outstanding common units, pro rata based on their percentage interest until such time as the Dealer Manager receives the full amount of the Dealer Manager contingent incentive fee under the Dealer Manager Agreement; ● Thereafter, (i) to the Record Holders of the Incentive Distribution Rights, 35%; (ii) to the Record Holders of the Outstanding Class B units, pro rata based on the number of Class B units owned, 35% multiplied by a fraction, the numerator of which is the number of Class B units outstanding and the denominator of which is 100,000 (currently, there are 62,500 Class B units outstanding; therefore, Class B units could receive 21.875%); (iii) the remaining amount to the Record Holders of outstanding common units, pro rata based on their percentage interest (currently 43.125%).

Key terms and conditions of the Fifth Amendment include:   ● As of the Effective Date, the borrowing base of the BF Credit Facility is $20,000,000.   ● As amended, the Partnership remains subject to a semiannual redetermination of its borrowing base, but the Partnership is only required to perform an annual analysis of its proven oil and natural gas reserves as of January 1 of each year.   ● The Partnership paid a loan fee to the Lender associated with the Fifth Amendment of $100,000.   ● Previously under the BF Loan Agreement, the Partnership was required to pay a $30,000 annual administrative fee to the Lender. Because BancFirst will be the only Lender effective March 1, 2024, the administrative fee has been waived through the Revised Maturity Date. The Partnership remains permitted to make distributions to its limited partners so long as the Partnership is in compliance with its debt service coverage ratio and no other event of default has occurred. Further, the Partnership is currently not subject to any hedging requirements under the BF Loan Agreement, as previously amended. All other terms and conditions of the BF Loan Agreement and its subsequent amendments remain in effect.

[1]The annual review of the PUDs resulted in a negative revision of approximately 5,361 MBOE. This revision was the result of 5,522 MBOE of downward adjustments attributable to changes in the future drill schedule and recovery projections, offset by 161 MBOE of upward adjustments attributable to changes in natural gas shrink and NGL yield when comparing the Partnership’s reserves at December 31, 2023 to December 31, 2022.[2]The annual review of the PUDs resulted in a positive revision of approximately 7,804 MBOE. This revision was the result of 8,177 MBOE of upward adjustments attributable to changes in the future drill schedule and offset by 373 MBOE of downward adjustments attributable to changes in natural gas shrink and NGL yield when comparing the Partnership’s reserves at December 31, 2022 to December 31, 2021.[3]The Partnership completed 6 new wells during 2023; therefore, the Partnership converted these 6 wells to proved developed reserves during 2023, which resulted in a downward adjustment to PUDs of 447 MBOE.[4]The Partnership completed 27 new wells during 2022; therefore, the Partnership converted these 27 wells to proved developed reserves during 2022, which resulted in a downward adjustment to PUDs of 5,523 MBOE.

[1]The annual review of the PUDs resulted in a negative revision of approximately 5,361 MBOE. This revision was the result of 5,522 MBOE of downward adjustments attributable to changes in the future drill schedule and recovery projections, offset by 161 MBOE of upward adjustments attributable to changes in natural gas shrink and NGL yield when comparing the Partnership’s reserves at December 31, 2023 to December 31, 2022.[2]The annual review of the PUDs resulted in a positive revision of approximately 7,804 MBOE. This revision was the result of 8,177 MBOE of upward adjustments attributable to changes in the future drill schedule and offset by 373 MBOE of downward adjustments attributable to changes in natural gas shrink and NGL yield when comparing the Partnership’s reserves at December 31, 2022 to December 31, 2021.[3]In 2023, extensions, discoveries and other additions of 619 MBOE were primarily attributable to successful drilling by the Partnership’s primary operator of the Sanish Field Assets.[4]In 2022, extensions, discoveries and other additions of 1,614 MBOE were primarily attributable to successful drilling by the Partnership’s primary operator of the Sanish Field Assets.[5]The Partnership completed 6 new wells during 2023; therefore, the Partnership converted these 6 wells to proved developed reserves during 2023, which resulted in a downward adjustment to PUDs of 447 MBOE.[6]The Partnership completed 27 new wells during 2022; therefore, the Partnership converted these 27 wells to proved developed reserves during 2022, which resulted in a downward adjustment to PUDs of 5,523 MBOE.[7]In 2023, extensions, discoveries and other additions of 619 MBOE were primarily attributable to successful drilling by the Partnership’s primary operator of the Sanish Field Assets.[8]In 2022, extensions, discoveries and other additions of 1,614 MBOE were primarily attributable to successful drilling by the Partnership’s primary operator of the Sanish Field Assets.[9]Revisions to previous estimates decreased proved reserves by a net amount of 7,196 MBOE. These revisions result from 5,522 MBOE of downward adjustments attributable to changes in the future drill schedule and recovery projections, 1,373 MBOE of downward adjustments attributable to well performance, and 301 MBOE of downward adjustments caused by lower oil, natural gas and NGL prices when comparing the Partnership’s reserve estimates at December 31, 2023 to December 31, 2022.[10]Revisions to previous estimates increased proved reserves by a net amount of 5,857 MBOE. These revisions result from 8,177 MBOE of upward adjustments attributable to changes in the future drill schedule and 164 MBOE of upward adjustments attributable caused by higher oil, natural gas and NGL prices when comparing the Partnership’s reserve estimates at December 31, 2022 to December 31, 2021, offset by 2,484 MBOE of downward adjustments attributable to well performance when comparing the Partnership’s reserve estimates at December 31, 2022 to December 31, 2021.
