The RRC has issued 2 drilling permits between 1984 and 1988, permitted to 8,500 ft.
It was permitted by SW Operating, Inc. and has since transferred to Wildfire Energy Operating LLC on the wellbore schedule.

Its lease has reported 117K barrels of oil and 111K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
