The RRC has issued one drilling permit, issued July 24, 1980, permitted to 3,200 ft.
It was permitted by Tahoe Oil & Cattle CO. and has since transferred to CM Oil CO. on the wellbore schedule.

Its lease has reported 42.7K barrels of oil and 4.09K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
