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 42.7M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 197 wells, so these are lease totals, not this well alone.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
