The RRC has issued one drilling permit, issued June 29, 1979, permitted to 4,515 ft.
It was permitted by Great Western Drlg. CO. and has since transferred to Basin Oil & Gas Operating LLC on the wellbore schedule.

Its lease has reported 2.29M barrels of oil and 488K mcf of gas since January 1993, last reporting in July 2026. The lease carries 29 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
