The RRC has issued one drilling permit, issued October 12, 1977, permitted to 11,500 ft.
It was permitted by Superior Oil Company, The and has since transferred to Apache Corporation on the wellbore schedule.

Its lease has reported 134K barrels of oil and 164K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
