Sau 33-4 #4 (API 42-383-34782) is a plugged well in Reagan County, plugged March 16, 2022, last operated by Apache Corporation.

The RRC has issued one drilling permit, issued June 3, 1997, permitted to 8,500 ft.

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

Completion filings report 3 formation tops, including Upr. Sprby, Lwr. Sprby, Dean.

Its lease has reported 107K barrels of oil and 1.09M mcf of gas since April 1998, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
