A change of operator of record is what the monthly reports show; it does not say why. Sales, mergers, renamed legal entities and new contract operators all look the same. Months link to that month's Pulse issue.
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.
