The RRC has issued one drilling permit, issued January 22, 1985, permitted to 7,500 ft.
It was permitted by Hng Fossil Fuels Company and has since transferred to Houston Pipe Line Company on the wellbore schedule.

Its 2 leases have reported 28.8K barrels of oil and 8 mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
