The RRC has issued 2 drilling permits between 1985 and 2006, permitted to 6,300 ft.
It was permitted by Texas American Resources Company and has since transferred to Trinity Operating (Usg) LLC on the wellbore schedule.

Its 2 leases have reported 385K barrels of oil and 45K mcf of gas since January 1993, last reporting in July 2026. The leases carry 55 wells, so these are lease totals, not this well alone.
