The RRC has issued one drilling permit, issued July 18, 1997, permitted to 8,203 ft.

It was permitted by Bta Oil Producers and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Its 2 leases have reported 81.8K barrels of oil and 151K mcf of gas since September 1997, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
