Andrews University 20 #1 (API 42-003-40497) is a well in Andrews County operated by Sabalo II Operating LLC, completed September 29, 2009 and listed as shut in on the RRC schedule, shut in April 1, 2025.
The RRC has issued one drilling permit (amended once), issued May 2, 2008, permitted to 11,504 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, Dean, Wolfcamp.
Its lease has reported 446K barrels of oil and 1.23M mcf of gas since July 2008, last reporting volume in April 2026. The lease carries 8 wells, so these are lease totals, not this well alone.

Well logs
3 logs loaded from the RRC's log index, the latest received Jun 27, 2011. Density, Neutron, Resistivity, Sonic. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
