Southwest Andrews Unit #7 (API 42-003-37335) is a well in Andrews County operated by Morningstar Operating LLC, completed December 14, 1993 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued September 1, 1993, permitted to 9,714 ft.

It was permitted by Union Oil Company Of California and has since transferred to Morningstar Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Yates, Wolfcamp, Pennsylvanian.

Its 3 leases have reported 2.62M barrels of oil and 4.14M mcf of gas since December 1993, last reporting volume in April 2026. The leases carry 45 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
