Sau 18-4 #4 (API 42-383-35317) is a well in Reagan County operated by Apache Corporation, completed April 26, 2003 and listed as shut in on the RRC schedule, shut in December 1, 2022.

The RRC has issued 2 drilling permits between 1997 and 2003, permitted to 8,246 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 55.3K barrels of oil and 304K mcf of gas since April 2003, with no volume in the three years through April 2026. The lease carries 2 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.
