Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying unaudited condensed consolidated financial statements are presented in accordance with U.S. generally accepted accounting principles (“GAAP”) and have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, certain information and footnote disclosures required by GAAP for complete financial statements have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the condensed consolidated financial statements have been included. For further information, refer to the consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on April 13, 2023. Our financial condition as of September 30, 2023, and operating results for the three and nine months ended September 30, 2023, are not necessarily indicative of the financial condition and results of operations that may be expected for any future interim period or for the year ending December 31, 2023.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates include the fair value of oil and gas properties acquired, oil and natural gas reserves that are used in the calculation of depreciation, depletion, amortization, and impairment of the carrying value of evaluated oil and natural gas properties; realizability of unevaluated properties; production and commodity price estimates used to record accrued oil and natural gas sales receivables; future prices of commodities used in the valuation of commodity derivative contracts; and the cost and timing of future asset retirement obligations. The Company evaluates its estimates on an on-going basis and bases its estimates on historical experience and on various other assumptions the Company believes to be reasonable. Due to inherent uncertainties, including the future prices of oil and natural gas, these estimates could change in the near term and such changes could be material.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted Accounting Standards On January 1, 2023, the Company adopted Accounting Standards Update (“ASU”) 2016-13 to Topic 326, Financial Instruments-Credit Losses, as amended by other related ASUs that provided targeted improvements. The standard changes the impairment model for trade receivables and other financial assets measured at amortized cost. This ASU requires the use of a new forward-looking “expected loss” model compared to the previous “incurred loss” model, resulting in accelerated recognition of credit losses. This ASU primarily applies to the Company’s accounts receivable balances, of which the majority are received within a short-term period of one to three months. The Company monitors the credit quality of its counterparties through review of collections, credit ratings, and other analyses. The Company develops its estimated allowance for credit losses primarily using an aging method and analyses of historical loss rates as well as consideration of current and future conditions that could impact its counterparties’ credit quality and liquidity. The adoption and implementation of this ASU did not have a material impact on the Company’s financial statements.
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The accompanying financial statements have been prepared in conformity with GAAP and include the accounts of U.S. Energy Corp. and its wholly-owned subsidiaries Energy One and New Horizon Resources. U.S. Energy Corp. accounts for its share of oil and gas exploration and production activities, in which it has a direct working interest, by reporting its proportionate share of assets, liabilities, revenues, costs, and cash flows within the relevant lines on the balance sheets, statements of operations, and statements of cash flows. All inter-company balances and transactions have been eliminated in consolidation.
Reclassification, Comparability Adjustment [Policy Text Block]	Reclassifications Certain prior year amounts are reclassified to conform to the current year presentation. Historically, the Company included gathering, transportation, and treating costs within lease operating expense on the condensed consolidated statement of operations. Effective July 1, 2023, the Company began classifying gathering, treating, and transportation costs in a separate line item, titled Gathering, transportation, and treating, on the condensed consolidated statement of operations and recast prior period results for this reclassification. This reclassification had no impact on the Company's net income, earnings per share, cash flows, or financial position. The Company revised historical periods to reflect this change in presentation.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Standards

On January 1, 2023, the Company adopted Accounting Standards Update (“ASU”) 2016-13 to Topic 326, Financial Instruments-Credit Losses, as amended by other related ASUs that provided targeted improvements. The standard changes the impairment model for trade receivables and other financial assets measured at amortized cost. This ASU requires the use of a new forward-looking “expected loss” model compared to the previous “incurred loss” model, resulting in accelerated recognition of credit losses. This ASU primarily applies to the Company’s accounts receivable balances, of which the majority are received within a short-term period of one to three months. The Company monitors the credit quality of its counterparties through review of collections, credit ratings, and other analyses. The Company develops its estimated allowance for credit losses primarily using an aging method and analyses of historical loss rates as well as consideration of current and future conditions that could impact its counterparties’ credit quality and liquidity. The adoption and implementation of this ASU did not have a material impact on the Company’s financial statements.

Consolidation, Policy [Policy Text Block]

Principles of Consolidation

The accompanying financial statements have been prepared in conformity with GAAP and include the accounts of U.S. Energy Corp. and its wholly-owned subsidiaries Energy One and New Horizon Resources. U.S. Energy Corp. accounts for its share of oil and gas exploration and production activities, in which it has a direct working interest, by reporting its proportionate share of assets, liabilities, revenues, costs, and cash flows within the relevant lines on the balance sheets, statements of operations, and statements of cash flows.

Reclassification, Comparability Adjustment [Policy Text Block]

Reclassifications

Certain prior year amounts are reclassified to conform to the current year presentation.

Historically, the Company included gathering, transportation, and treating costs within lease operating expense on the condensed consolidated statement of operations. Effective July 1, 2023, the Company began classifying gathering, treating, and transportation costs in a separate line item, titled Gathering, transportation, and treating, on the condensed consolidated statement of operations and recast prior period results for this reclassification. This reclassification had no impact on the Company's net income, earnings per share, cash flows, or financial position. The Company revised historical periods to reflect this change in presentation.
