The RRC has issued 2 drilling permits between 1980 and 1983, permitted to 11,600 ft.
It was permitted by Gulf Oil Corp. and has since transferred to Mountainside Energy Operating L on the wellbore schedule.

Its 2 leases have reported 27.1K barrels of oil and 1.06M mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
