Sau Mariner 20-1 #1
Reagan County · Spraberry (Trend Area) field · Shut In · Vertical
Sau Mariner 20-1 #1 (API 42-383-34933) is a well in Reagan County operated by Apache Corporation, completed July 30, 1998 and listed as shut in on the RRC schedule, shut in February 1, 2025.
The RRC has issued one drilling permit (amended once), issued April 30, 1998, permitted to 8,360 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 168K barrels of oil and 902K mcf of gas since July 1998, last reporting volume in April 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
