Sau 8 #4C (API 42-383-35895) is a well in Reagan County operated by Apache Corporation, completed March 12, 2007 and listed as shut in on the RRC schedule, shut in October 1, 2020.

The RRC has issued one drilling permit, issued January 5, 2007, permitted to 8,073 ft.

It was permitted by Mariner Energy, Inc. and has since transferred to Apache Corporation on the wellbore schedule.

Completion filings report 2 formation tops, including Spraberry, Dean.

Its lease has reported 765K barrels of oil and 5.07M mcf of gas since January 1993, last reporting volume in June 2023. The lease carries 23 wells, so these are lease totals, not this well alone.

Well logs

1 log loaded from the RRC's log index, the latest received Aug 18, 2008. Neutron. 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.
