Andrews University 28 #11 (API 42-003-41887) is a well in Andrews County operated by Sabalo II Operating LLC, completed December 19, 2010 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued August 17, 2010, permitted to 11,500 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 522K barrels of oil and 1.81M mcf of gas since June 2008, last reporting in July 2026. The lease carries 16 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.
