The RRC has issued one drilling permit, issued May 10, 1979, permitted to 4,664 ft.
It was permitted by Tesoro Petroleum Corporation and has since transferred to White Marlin Operating CO LLC on the wellbore schedule.

Its lease has reported 194K barrels of oil and 22.5K mcf of gas since January 1993, last reporting in July 2026. The lease carries 42 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
