The RRC has issued 3 drilling permits between 1982 and 2006, permitted to 6,000 ft.

It was permitted by T - C Oil Company and has since transferred to T-C Oil Company LLC on the wellbore schedule.

Its 3 leases have reported 6.52M barrels of oil and 31.8M mcf of gas since January 1993, last reporting in July 2026. The leases carry 116 wells, so these are lease totals, not this well alone.
