Accounting Policies [Abstract]
Full Cost Accounting	Full Cost Accounting The Partnership follows the full-cost method of accounting for its oil and gas activities. Under the full-cost method, all productive and non-productive costs incurred in the acquisition, exploration and development of oil and gas properties are capitalized. Depreciation, depletion and amortization of oil and gas properties subject to amortization is computed on the units-of-production method based on the proved reserves underlying the oil and gas properties. At March 31, 2019 and 2018, all capitalized costs were subject to amortization. Proceeds from the sale or other disposition of properties are credited to the full cost pool. Gains and losses are not recognized unless such adjustments would significantly alter the relationship between capitalized costs and the proved oil and gas reserves. Capitalized costs are subject to a quarterly ceiling test that limits such costs to the aggregate of the present value of estimated future net cash flows of proved reserves, computed using the 12-month unweighted average of first-day-of-the-month oil and natural gas prices, discounted at 10%, and the lower of cost or fair value of unproved properties. If unamortized costs capitalized exceed the ceiling, the excess is charged to expense in the period the excess occurs. There were no cost ceiling write-downs for the three months ended March 31, 2019 or 2018.
Sale of Leasehold	Sale of Leasehold In the first quarter of 2019 the Partnership received $264,000 in sales proceeds from the sale of the Marathon Road leasehold prospect. No wells were included in this sale. Under the full cost method all oil and gas properties in each country are combined into a common pool. Conceptually, each property loses its separate identity, and sales and abandonments of properties are generally treated as adjustments of capitalized costs with no gains or losses recognized. Therefore, the $264,000 in sales proceeds were recorded as an adjustment to the full cost pool and no gain or loss was recognized.
Recent Accounting Developments	Recent Accounting Developments In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, “Leases.” ASU 2016-02 requires the recognition of lease assets and lease liabilities by lessees for those leases currently classified as operating leases and makes certain changes to the way lease expenses are accounted for. This update is effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. This update should be applied using a modified retrospective approach, and early adoption is permitted. In January 2018, the FASB issued ASU 2018-01, which permits an entity to elect an optional transition practical expedient to not evaluate land easements that exist or expire before the Partnership’s adoption of Topic 842 and that were not previously accounted for as leases under Topic 840. The Partnership adopted the new standard on the effective date of January 1, 2019. As the Partnership has no leases, this standard had no impact on its financial statements.
