The RRC has issued 2 drilling permits between 1987 and 2014, permitted to 8,700 ft.
It was permitted by Hunt Oil Company and has since transferred to Union Pacific Resources Company on the wellbore schedule.

Its 3 leases have reported 54.8K barrels of oil and 705K mcf of gas since January 1993, last reporting in July 2026. The leases carry 19 wells, so these are lease totals, not this well alone.
