The RRC has issued one drilling permit, issued June 5, 1990, permitted to 5,000 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 3.45M barrels of oil and 1.61M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 124 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
