The RRC has issued 2 drilling permits in 1981, permitted to 8,800 ft.
It was permitted by Williams, Clayton W., JR. and has since transferred to Wildfire Energy Operating LLC on the wellbore schedule.
Its 4 leases have reported 99.1K barrels of oil and 1.39M mcf of gas since January 1993, last reporting in July 2026. The leases carry 8 wells, so these are lease totals, not this well alone.
