The RRC has issued 2 drilling permits between 1991 and 2004, permitted to 10,550 ft.
It was permitted by Texas American Resources Company and has since transferred to Trinity Operating (Usg) LLC on the wellbore schedule.

Its lease has reported 252K barrels of oil and 628K mcf of gas since January 1993, last reporting in July 2021. The lease carries 2 wells, so these are lease totals, not this well alone.
