The RRC has issued one drilling permit, issued November 6, 1984, permitted to 5,100 ft.
It was permitted by Sun Expl. & Prod. CO.-Midland and has since transferred to Walkabout Operating LLC on the wellbore schedule.

Its lease has reported 175K barrels of oil and 35.4K mcf of gas since January 1993, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
