The RRC has issued 2 drilling permits between 1990 and 1995, permitted to 5,018 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its lease has reported 25.1M barrels of oil and 40.1M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 352 wells, so these are lease totals, not this well alone.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
