It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Southwest Royalties Inc. on the wellbore schedule.

Its lease has reported 7.38K barrels of oil and 21 mcf of gas since January 1993, last reporting in May 2017. The lease carries 4 wells, so these are lease totals, not this well alone.
