Segment Reporting, CODM, Profit (Loss) Measure, How Used, Description         The CODM uses net income (loss) as presented in the accompanying statements of operations to measure E&P Segment profit or loss, and to evaluate income generated from E&P Segment assets in deciding whether to reinvest profits into operational activities or to use profits for other purposes, such as debt reduction, acquisitions, or our Stock Repurchase Program. Additionally, net income (loss) is used in assessing budget versus actual results and in benchmarking to our competitors
