The RRC has issued one drilling permit, issued November 6, 1985, permitted to 8,200 ft.
It was permitted by Diamond Shamrock Exploration CO. and has since transferred to Endeavor Energy Resources L.P. on the wellbore schedule.

Its 2 leases have reported 324K barrels of oil and 788K mcf of gas since January 1993, last reporting in August 2024. The leases carry 7 wells, so these are lease totals, not this well alone.
