The RRC has issued 2 drilling permits between 1987 and 1992, permitted to 8,700 ft.
It was permitted by Amoco Production Company and has since transferred to Endeavor Energy Resources L.P. on the wellbore schedule.

Its 5 leases have reported 36K barrels of oil and 129K mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.
