Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation. The consolidated financial statements include the accounts of Mexco Energy Corporation and its wholly owned subsidiaries. All significant intercompany balances and transactions associated with the consolidated operations have been eliminated.
Estimates and Assumptions	Estimates and Assumptions. In preparing financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”), management is required to make informed judgments, estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and affect the reported amounts of revenues and expenses during the reporting period. In addition, significant estimates are used in determining proved oil and gas reserves. Although management believes its estimates and assumptions are reasonable, actual results may differ materially from those estimates. The estimate of the Company’s oil and natural gas reserves, which is used to compute depreciation, depletion, amortization and impairment of oil and gas properties, is the most significant of the estimates and assumptions that affect these reported results.
Interim Financial Statements	Interim Financial Statements. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting only of normal recurring accruals) necessary to present fairly the financial position of the Company as of June 30, 2019, and the results of its operations and cash flows for the interim periods ended June 30, 2019 and 2018. The consolidated financial statements as of June 30, 2019 and for the three month periods ended June 30, 2019 and 2018 are unaudited. The consolidated balance sheet as of March 31, 2019 was derived from the audited balance sheet filed in the Company’s 2019 annual report on Form 10-K filed with the Securities and Exchange Commission (“SEC”). The results of operations for the periods presented are not necessarily indicative of the results to be expected for a full year. The accounting policies followed by the Company are set forth in more detail in Note 2 of the “Notes to Consolidated Financial Statements” in the Form 10-K. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted in this Form 10-Q pursuant to the rules and regulations of the SEC. However, the disclosures herein are adequate to make the information presented not misleading. It is suggested that these consolidated financial statements be read in conjunction with the consolidated financial statements and notes thereto included in the Form 10-K.

Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements. In February 2016, the FASB issued ASU 2016-02, Topic 842 Leases and subsequent amendments to the initial guidance: ASU 2018-10, ASU 2018-11, ASU 2018-20 and ASU 2019-01 (collectively, Topic 842). The standard establishes a right-of-use (“ROU”) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term greater than one year. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The Company has determined that it has only one operating lease. The Company adopted Topic 842 on April 1, 2019 using the modified retrospective approach and the impact of the adoption resulted in the recognition of a ROU asset and liability on the Company’s consolidated balance sheets of $141,385. The current portion of the operating lease liability is included in Total current liabilities and the noncurrent portion of the operating lease liability is included in Total long-term liabilities on the Company’s consolidated balance sheets. Prior periods have not been adjusted. See Note 5 – Leases for additional discussion.
