Segment Reporting, CODM, Profit (Loss) Measure, How Used, Description             The CODM uses net income 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 is used to assess budget versus actual results and to benchmark against our competitors
