The RRC has issued one drilling permit, issued February 21, 1990, permitted to 11,980 ft.
It was permitted by Four Star Oil And Gas Company and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its lease has reported 473K barrels of oil and 69.9K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
