Exxon Mobil Corp. v. Wyo. Oil & Gas Conservation Comm'nAnnotate this Case
The Wyoming Oil and Gas Conservation Commission approved Cimarex Energy Company's plan to reinject waste carbon dioxide and hydrogen sulfide into a producing natural gas formation in southwest Wyoming over the objection of Exxon Mobil Corporation. Exxon appealed. The district court affirmed the Commission's decision. The Supreme Court affirmed in part and reversed and remanded in part, holding (1) the Commission properly denied Exxon's petition for a rehearing; but (2) the Commission failed to provide sufficient findings of fact as to whether Cimarex's plan to reinject carbon dioxide and hydrogen sulfide would result in waste of natural gas and improperly interfere with Exxon's correlative rights. Remanded to the Commission to make appropriate findings of both basic and ultimate facts.
