The RRC has issued one drilling permit, issued October 25, 1985, permitted to 3,600 ft.
It was permitted by Leonard, J. A. and has since transferred to Rusk Energy Operating LLC on the wellbore schedule.

Its lease has reported 34.4K barrels of oil and 51.8K mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
