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 gas company focused on delivering a sustainable dividend yield to its stockholders through the ownership, management, and development of oil and gas properties. The Company's long-term goal is to build a diversified portfolio of oil and 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. Our producing assets consist of our interests in the Delhi Holt-Bryant Unit in the Delhi field in Northeast Louisiana, a CO2 enhanced oil recovery project, our interests in the Hamilton Dome field located in Hot Springs County, Wyoming, a secondary recovery field utilizing water injection wells to pressurize the reservoir, and overriding royalty interests in two 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 2020 Annual Report on Form 10-K for the fiscal year ended June 30, 2020, as filed with the SEC. The results of operations for interim periods are not necessarily indicative of results to be expected for a full fiscal year. Principles of Consolidation and Reporting. Our unaudited consolidated condensed financial statements include the accounts of EPM and its wholly owned subsidiaries (the "Company"). All significant intercompany transactions have been eliminated in consolidation. The unaudited consolidated condensed financial statements for the previous year may include certain reclassifications to conform to the current presentation. Any such reclassifications have no impact on previously reported net income or stockholders' equity. 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 and Hamilton Dome fields in which we hold non-operated interests. In 2020, primarily driven by the COVID-19 pandemic and actions taken by OPEC+, the benchmark price of WTI declined to levels that adversely impacted our earnings. The Company expects the price of crude oil to remain volatile as evidenced by the continued volatility in the futures market. We cannot predict the duration of such volatility nor the current supply-demand imbalance, but must be prepared for crude oil prices to remain depressed for an extended period and for its potential effects on our business, financial condition, results of operations, and cash flows. The nature of the COVID-19 pandemic makes it extremely difficult to predict the impact on the Company’s business and operations. However, the likely overall economic impact of the pandemic is viewed as highly negative to the general economy, especially the oil and natural gas industry. In 2020, primarily driven by the COVID-19 pandemic and actions taken by OPEC+, the benchmark price of WTI dropped significantly. The Company expects the price of crude oil to remain volatile as evidenced by the continued volatility in the futures market. Uncertainty regarding the future actions of foreign oil producers, such as Saudi Arabia and Russia, and the risk that they take actions that will prolong or exacerbate the current over-supply of crude oil is also contributing to the recent decline in oil prices. In addition, future legislative or regulatory changes as a result of the United States election in 2020 may result in increased costs and decreased revenues, cash flows and liquidity. New or changed laws and regulations could have a material adverse effect on our business. In response to the pandemic and the associated negative price impact, both of our operators have taken actions such as reducing operating and capital expenditures. At Hamilton Dome the operator had also temporarily shut-in some producing wells, some of which have subsequently been returned to production. The Company’s property interests are not operated by the Company and involve other third-party working interest owners. As a result, we have 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. The Company is focused on 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. The Company was able to transition the operation of its business with minimal disruption and to maintain 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, and (f) commitments and contingencies. We analyze our estimates based on historical experience and various other assumptions that we believe to be reasonable. While we believe that our estimates and assumptions used in preparation of the unaudited consolidated condensed financial statements are appropriate, actual results could differ from those estimates.
