Sau Mariner 31-2 #2B (API 42-383-36012) is a well in Reagan County operated by Apache Corporation, completed September 6, 2007 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued July 12, 2007, permitted to 8,550 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 64.4K barrels of oil and 586K mcf of gas since March 2005, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
