The RRC has issued 2 drilling permits (amended once) between 1987 and 1991, permitted to 7,313 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its 2 leases have reported 5.98K barrels of oil and 101K 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.
