Southwest Andrews Unit #9 (API 42-003-04871) is a plugged well in Andrews County, plugged December 17, 2002, last operated by Morningstar Operating LLC.
The RRC has issued 2 drilling permits between 1993 and 1994, permitted to 9,570 ft.
It was permitted by Union Oil Company Of California and has since transferred to Morningstar Operating LLC on the wellbore schedule.
Its 6 leases have reported 2.9M barrels of oil and 4.63M mcf of gas since January 1993, last reporting in July 2026. The leases carry 55 wells, so these are lease totals, not this well alone.
