Saint Andrews Unit #4
Andrews County · Saint Wilma (Strawn) field · Shut In · Vertical
Saint Andrews Unit #4 (API 42-003-42576) is a well in Andrews County operated by Sabalo II Operating LLC, completed October 20, 2011 and listed as shut in on the RRC schedule, shut in May 1, 2019.
The RRC has issued one drilling permit, issued February 2, 2011, permitted to 11,286 ft.
It was permitted by Exl Petroleum, LP and has since transferred to Sabalo II Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Wolfcamp, Strawn.
Its 2 leases have reported 2.1M barrels of oil and 4.82M mcf of gas since March 2009, last reporting volume in April 2026. The leases carry 110 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Oct 3, 2018. Cement bond. 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.
