The RRC has issued 5 drilling permits between 1993 and 2019, permitted to 7,500 ft.
It was permitted by T-C Oil Company, LLC and has since transferred to T - C Oil Company on the wellbore schedule.

Its 5 leases have reported 752K barrels of oil and 1.29M mcf of gas since January 1993, last reporting in July 2026. The leases carry 28 wells, so these are lease totals, not this well alone.
