The RRC has issued one drilling permit, issued December 15, 1981, permitted to 5,350 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 878K barrels of oil and 12K mcf of gas since January 1993, last reporting in July 2026. The lease carries 15 wells, so these are lease totals, not this well alone.
