Segment Reporting [Abstract]

Business Segment Information

Business Segment Information    

    The Company reports financial results for four segments: Exploration and Production, Pipeline and Storage, Gathering and Utility.  The division of the Company’s operations into reportable segments is based upon a combination of factors including differences in products and services, regulatory environment and geographic factors.

    The data presented in the tables below reflect financial information for the segments and reconcile to consolidated amounts.  As stated in the 2022 Form 10-K, the Company evaluates segment performance based on income before discontinued operations (when applicable).  When this is not applicable, the Company evaluates performance based on net income.  There have not been any changes in the basis of segmentation nor in the basis of measuring segment profit or loss from those used in the Company’s 2022 Form 10-K.  A listing of segment assets at June 30, 2023 and September 30, 2022 is shown in the tables below.
