Andrews University 21 #10 (API 42-003-41708) is a well in Andrews County operated by Sabalo II Operating LLC, completed July 20, 2011 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued June 23, 2010, permitted to 11,402 ft.

It was permitted by Williams, Clayton Energy, Inc. and has since transferred to Sabalo II Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Clear Fork, Spraberry, Wolfcamp, Strawn.

Its lease has reported 518K barrels of oil and 1.53M mcf of gas since February 2008, last reporting in July 2026. The lease carries 12 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.
