Southwest Mcelroy Unit #38 (API 42-461-10599) is a well in Upton County operated by United Oil & Shale LLC, completed November 17, 2011 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued November 17, 2011, permitted to 3,250 ft.

It was permitted by Walsh & Watts, Inc. and has since transferred to United Oil & Shale LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Red Bed, Rustler, Grayburg.

Its lease has reported 703K barrels of oil and 127K mcf of gas since January 1993, last reporting in July 2026. The lease carries 54 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.
