The RRC has issued 2 drilling permits between 1992 and 1995, permitted to 5,468 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 14.8M barrels of oil and 43M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 197 wells, so these are lease totals, not this well alone.
