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

Its lease has reported 1.18M barrels of oil and 13K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 94 wells, so these are lease totals, not this well alone.
