| Disclosure Text Block [Abstract] | |
| Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | Note 1. Partnership Organization Energy Resources 12, L.P. (the “Partnership”) was formed as a Delaware limited partnership. The initial capitalization of the Partnership of $1,000 occurred on December 30, 2016. The Partnership is offering common units of limited partner interest (the “common units”) on a best-efforts basis with the intention of raising up to $350,000,001 of capital, consisting of 17,631,579 common units. The Partnership’s offering was declared effective by the Securities and Exchange Commission (“SEC”) on May 17, 2017. Upon raising a minimum of $25,000,010, which was completed on July 25, 2017, the subscribers to the common units were admitted, the common units were issued and the Partnership commenced operations (“Minimum Offering”). The Partnership’s primary investment objectives are to (i) acquire producing and non-producing oil and gas properties with development potential to be operated by third-party operators, and to enhance the value of the properties through drilling and other development activities, (ii) make distributions to the holders of the common units, (iii) engage in a liquidity transaction after five to seven years, in which all properties are sold and the sales proceeds are distributed to the partners, merge with another entity, or list the common units on a national securities exchange, and (iv) permit holders of common units to invest in oil and gas properties in a tax efficient basis. The proceeds from the sale of the common units primarily will be used to acquire producing and non-producing oil and natural gas properties onshore in the United States, and to develop those properties. The general partner of the Partnership is Energy Resources 12 GP, LLC (the “General Partner”). The organizational limited partner is DMOG, LLC. The General Partner manages and controls the business affairs of the Partnership. David Lerner Associates, Inc. (the “Managing Dealer”), is acting as the dealer manager for the offering of the common units. 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 unaudited financial statements have been prepared in accordance with the instructions for Article 10 of SEC Regulation S-X. Accordingly, they do not include all of the information required by generally accepted accounting principles (“GAAP”) in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. These unaudited financial statements should be read in conjunction with the Partnership’s audited December 31, 2016 financial statements. Operating results for the three and six months ended June 30, 2017 are not necessarily indicative of the results that may be expected for the twelve-month period ending December 31, 2017. 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. Offering Costs Offering costs will be deferred and recorded as deferred offering costs until the Partnership’s Minimum Offering is completed. Upon reaching the Minimum Offering, these costs will be recorded as a reduction to Partners’ equity. Use of Estimates The preparation of financial statements in conformity with United States GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Recently Adopted Accounting Standards In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2017-01, Business Combinations (Topic 805), which amends the existing accounting standards to clarify the definition of a business and assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. For public entities, the guidance is effective for reporting periods beginning after December 15, 2017, including interim periods within those periods, and should be applied prospectively on or after the effective date. The Partnership has adopted this standard effective January 1, 2017. |

| Partners' Capital Notes [Abstract] | |
| Partners' Capital Notes Disclosure [Text Block] | Note 3. Capital Contribution and Partners’ Equity The General Partner and organizational limited partner have made initial capital contributions totaling $1,000 to the Partnership. Upon closing of the Minimum Offering, the organizational limited partner will withdraw, its initial capital contribution of $990 will be returned, the General Partner will receive Incentive Distribution Rights (defined below), and will be reimbursed for its documented third party out-of-pocket expenses incurred in organizing the Partnership and offering the common units. As of June 30, 2017, subscriptions totaling approximately $21.2 million had been received in the escrow account. As of July 25, 2017, the Partnership completed its Minimum Offering and received gross proceeds of approximately $25.3 million and proceeds net of the Managing Dealer’s selling commission and marketing expenses of approximately $23.8 million for the sale of approximately 1.3 million common units. The Partnership intends to continue to raise capital through a best-efforts offering of common units by the Managing Dealer at $19.00 until it raises gross proceeds of $50.0 million, at which time the price per common unit will increase to $20.00. Under the agreement with the Managing Dealer, the Managing Dealer receives a total of 6% in selling commissions and a marketing expense allowance based on gross proceeds of the common units sold. The Managing Dealer will also have Dealer Manager Incentive Fees (defined below) where the Managing Dealer could also receive distributions up to an additional 4% of gross proceeds of the common units sold in the Partnership’s best-efforts offering as outlined in the prospectus based on the performance of the Partnership. 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 with respect to the Incentive Distribution Rights and will not pay the Dealer Manager Incentive Fees to the Managing Dealer, until Payout occurs. The Agreement of Limited Partnership of the Partnership (the “Partnership Agreement”) provides that “Payout”, which is defined below, 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, 30%; (ii) to the Managing Dealer, the “Dealer Manager Incentive Fees”, 30%, until such time as the Managing Dealer receives 4% of the gross proceeds of the common units sold; and (iii) to the Record Holders of outstanding common units, 40%, pro rata based on their percentage interest. · Thereafter, (i) to the Record Holders of the Incentive Distribution Rights, 60%; and (ii) to the Record Holders of outstanding common units, 40%, pro rata based on their percentage interest. 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. |

| Debt Disclosure [Text Block] | Note 4. Note Payable In February 2017, the Partnership obtained an unsecured line of credit with Bank of America in the principal amount of $500,000 to fund some of its offering and operating costs. As of June 30, 2017, the outstanding balance on the line of credit was $229,000, which approximated its fair value. The Partnership repaid the line of credit, which bore interest at a variable rate based on the London InterBank Offered Rate (LIBOR), using proceeds from the sale of common units on July 25, 2017 without a prepayment premium or penalty. Glade M. Knight, the General Partner’s Chief Executive Officer, and David S. McKenney, the General Partner’s Chief Financial Officer, had guaranteed repayment of the line of credit and did not receive any consideration in exchange for providing this guarantee. |

| Related Party Transactions Disclosure [Text Block] | Note 5. Related Parties 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. The Partnership has agreed to pay the general partner an advisory fee to manage the day-to-day affairs of the Partnership, including serving as an investment advisor and consultant in connection with the acquisition, development, operation and disposition of oil and gas properties and other assets of the Partnership. Subsequent to the Partnership’s first asset purchase, the Partnership will pay quarterly an annual fee of 0.5% of the total gross equity proceeds raised by the Partnership in its offering as outlined in the prospectus, in addition to certain reimbursable expenses. The fees paid to the general partner will be expensed as incurred. The Partnership will also reimburse the General Partner for any costs incurred by the General Partner in organizing the Partnership or incurred in the offering of the common units. For the three and six months ended June 30, 2017, a member of the General Partner has incurred approximately $19,000 in expenses to be reimbursed by the Partnership. The Chief Executive Officer and Chief Financial Officer of the Partnership’s general partner are also the Chief Executive Officer and Chief Financial Officer of Energy 11 GP, LLC, the general partner of Energy 11, L.P. The general partner anticipates that it will share accounting and administrative resources, including personnel, with Energy 11, L.P. to ensure effective staffing of the Partnership. The cost of these accounting and administrative resources will be shared between the partnerships. Other than through the Partnership’s Chief Executive Officer and Chief Financial Officer and the shared accounting and administrative resources, there is no affiliation between the Partnership and Energy 11, L.P. |
