Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Resources is an energy services company primarily engaged in the sale and distribution of natural gas. The condensed consolidated financial statements include the accounts of Resources and its wholly owned subsidiaries: Roanoke Gas and Midstream. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of only normal recurring accruals) necessary to fairly present Resources' financial position as of March 31, 2025, cash flows for the six months ended March 31, 2025 and 2024, and the results of its operations, comprehensive income, and changes in stockholders' equity for the three and six months ended March 31, 2025 and 2024. The results of operations for the three and six months ended March 31, 2025 are not indicative of the results to be expected for the fiscal year ending September 30, 2025 as quarterly earnings are affected by the highly seasonal nature of the business and weather conditions generally result in greater earnings during the winter months. The unaudited condensed consolidated financial statements and related notes are presented under the rules and regulations of the SEC. Pursuant to those rules, certain information and note disclosures normally included in the annual financial statements prepared in accordance with GAAP have been condensed or omitted. Although the Company believes that the disclosures are adequate, the unaudited condensed consolidated financial statements and the related notes should be read in conjunction with the financial statements and notes contained in the Company’s Form 10-K for the year ended September 30, 2024. The September 30, 2024 consolidated balance sheet was included in the Company’s audited financial statements included in Form 10-K. Midstream has $35.6 million of current maturities of long-term debt due in the 12 months following the filing date of this Form 10-Q. This amount exceeds the liquidity available to the Company through currently executed agreements and anticipated operating cash flows over this period. Management expects it will refinance $26.6 million prior to December 31, 2025 and $9 million prior to May 2, 2026. The Company has refinanced this debt in the past and is currently in discussions with lenders concerning refinancing the debt. Management believes discussions to date have been positive and that MVP's successful operation supports the likelihood of refinancing. Such refinancing cannot be completed without taking additional actions involving a third party. As a result, under ASU 2014-15, substantial doubt exists about the Company's ability to continue as a going concern. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. Actual results could differ from those estimates. The Company’s significant accounting policies are described in Note 1 to the consolidated financial statements contained in the Company's Form 10-K for the year ended September 30, 2024. Certain amounts previously disclosed have been reclassified to conform to current year presentations.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued or Adopted Accounting Standards In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. The new guidance is designed to provide users of financial statements with improved reportable segment disclosures, primarily through enhanced disclosures about significant segment expenses, other segment items and measures of segment profit or loss used by the chief operating decision maker (CODM). Additionally, the new guidance requires a public entity to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually, which the Company currently discloses on an interim basis. The new guidance is effective for the Company for fiscal year beginning October 1, 2024 and interim periods within fiscal year beginning October 1, 2025. The Company is currently assessing the impact of the new guidance on its financial statement disclosures, and expects the adoption of this standard will result in expanded disclosures within the segment reporting footnote, specifically regarding the information provided to the CODM and how the CODM uses the information in assessing the performance of each segment. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The new guidance requires that on an annual basis public business entities disclose specific categories in the rate reconciliation table and provide additional information for reconciling items that meet a quantitative threshold (items equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory rate). The required disclosures will provide more granularity regarding the payment of income taxes to federal, state and foreign entities. The Company does not expect certain requirements of this ASU to have a significant impact to its current disclosures as all of its operations are domestic and reside in two states. Changes to the rate reconciliation table will result in additional disclosure. The new guidance is effective for the Company for annual periods beginning October 1, 2025. In November 2024, the SEC issued ASU 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. The new guidance requires public business entities to disclose certain additional detail about expenses including, among other items, purchases of inventory, employee compensation, depreciation and intangible asset amortization included within each income statement expense line items within continuing operations. The guidance also requires disclosure of the total amount of selling expenses and the Company’s definition of selling expenses. Such disclosures must be made on an annual and interim basis and integrated with existing disclosure requirements in a tabular format in the footnotes to the financial statements. Further, in January 2025, the SEC issued ASU 2025-01, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures: Clarifying the Effective Date, which clarified the effective date of ASU 2024-03. The new guidance is effective for the Company for fiscal year beginning October 1, 2027 and interim periods within fiscal year beginning October 1, 2028. The Company is currently assessing the impacts of the new guidance on its financial statement disclosures. Other accounting standards that have been issued by the FASB, SEC or other standard-setting bodies are not currently applicable to the Company or are not expected to have a material impact on the Company’s financial position, results of operations or cash flows.
