Notes
The operator of record is the company named on the state's monthly report rows; parent companies and ownership are not shown. Volumes are those printed for its wells, as first reported: confidential wells are withheld, and before May 2015 wells in unitized pools appear only inside unit totals. Status codes are the Industrial Commission's, as its wells layer lists them; they are not a judgement of compliance. Nothing here is a financial, legal or engineering assessment.
Built November 8, 2026 from reports through August 2026 and the wells layer of November 6, 2026. Corrections: see contact.
