Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Preparation	Organization and Basis of Preparation Nature of Operations. Evolution Petroleum Corporation is an oil and natural gas company focused on delivering a sustainable dividend yield to its stockholders through the ownership, management, and development of producing oil and natural gas properties. The Company's long-term goal is to build a diversified portfolio of oil and natural gas assets primarily through acquisitions while seeking opportunities to maintain and increase production through selective development, production enhancement, and other exploitation efforts on its properties. The Company’s producing assets consist of interests in the Delhi Holt-Bryant Unit in the Delhi field in Northeast Louisiana, a CO2 enhanced oil recovery (“EOR”) project, interests in the Hamilton Dome field located in Hot Springs County, Wyoming, a secondary recovery field utilizing water injection wells to pressurize the reservoir, interests in the Barnett Shale located in North Texas, a natural gas producing shale reservoir, and minimal overriding royalty interests in four onshore Texas wells. Interim Financial Statements. The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and the appropriate rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. All adjustments (consisting of normal recurring accruals) which are, in the opinion of management, necessary for a fair presentation of the financial position and results of operations for the interim periods presented have been included. The interim financial information and notes hereto should be read in conjunction with the Company’s 2021 Annual Report on Form 10-K for the fiscal year ended June 30, 2021, as filed with the SEC on September 14, 2021. The results of operations for interim periods are not necessarily indicative of results to be expected for a full fiscal year. The Company has evaluated events and transactions through the date of issuance of these unaudited consolidated condensed financial statements. Principles of Consolidation and Reporting. The Company’s unaudited consolidated condensed financial statements include the accounts of Evolution Petroleum Corporation and its wholly-owned subsidiaries (the “Company”). All significant intercompany transactions have been eliminated in consolidation. Risk and Uncertainties. The Company is continuously monitoring the current and potential impacts of the COVID-19 pandemic on its business, including how it has and may continue to impact its financial results, liquidity, employees, and the operations of the Delhi field, Hamilton Dome field, and its Barnett Shale assets in which it holds non-operated interests. All of the Company’s property interests are not operated by the Company and involve other third-party working interest owners. As a result, the Company has limited ability to influence or control the operation or future development of such properties. However, the Company has been proactive with its third-party operators to review spending and alter plans as appropriate. In response to the COVID-19 pandemic, the Company has focused on putting long-term measures in place to prevent future disruptions, maintaining its operations and system of controls remotely, and has implemented its business continuity plans in order to allow its employees to securely work from home or in the corporate office. The Company has been able to transition the operation of its business with minimal disruption and has maintained its system of internal controls and procedures. Use of Estimates. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include (a) reserve quantities and estimated future cash flows associated with proved reserves, which may significantly impact depletion expense and potential impairments of oil and natural gas properties, (b) asset retirement obligations, (c) stock-based compensation, (d) fair values of derivative assets and liabilities, (e) income taxes and the valuation of deferred tax assets, (f) commitments and contingencies, and (g) oil, natural gas, and natural gas liquids (“NGL”) revenues. The Company analyzes estimates based on historical experience and various other assumptions that are believed to be reasonable. While the Company believes that the estimates and assumptions used in preparation of the unaudited consolidated condensed financial statements are appropriate, actual results could differ from those estimates.
