The RRC has issued one drilling permit, issued July 3, 1987, permitted to 8,180 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Western Energy Group LLC on the wellbore schedule.
Its lease has reported 232K barrels of oil and 631K mcf of gas since January 1993, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
