Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We file a consolidated federal income tax return in the United States and various combined and separate filings in several state and local jurisdictions. There were no unrecognized tax benefits, nor any accrued interest or penalties associated with unrecognized tax benefits during any periods presented in these unaudited consolidated condensed financial statements. We believe that we have appropriate support for the income tax positions taken and to be taken on the Company's tax returns and that the accruals for tax liabilities are adequate for all open years based on our assessment of many factors including past experience and interpretations of tax law applied to the facts of each matter. The Company’s federal and state income tax returns are open to audit under the statute of limitations for the fiscal years ended June 30, 2016 through June 30, 2019 for federal tax purposes and for the fiscal years ended June 30, 2015 through June 30, 2019 for state tax purposes. To the extent we utilize net operating losses generated in earlier years, such earlier years may also be subject to audit. At September 30, 2020, the Company had a $3.1 million receivable for remaining income tax refunds related to amended federal and state tax returns for the years ended June 30, 2017, and 2018 filed in late fiscal 2020 for Enhanced Oil Recovery credits related to our Delhi field interests. For the three months ended September 30, 2020, we recognized income tax benefit of $2.3 million and had an effective tax rate of 24.4% compared to income tax expense of $0.5 million and an effective tax rate of 15.6% for the three months ended September 30, 2019. During the three months ended September 30, 2020, we recognized a $0.5 million federal net operating loss carryback (Note 6 – Other Assets) and intend to request its refund when we file our fiscal 2021 Federal return. Our effective tax rate will typically differ from the statutory federal rate as a result of state income taxes, primarily in the State of Louisiana, and differences related to percentage depletion in excess of basis, stock-based compensation, and other permanent differences. For both periods, our respective statutory federal tax rate was 21%.
