WELL · 42-461-35612 · DISTRICT 7
Thomas #1
Upton County · Spraberry (Trend Area) field · Shut IN · Vertical
Thomas #1 (API 42-461-35612) is a well in Upton County operated by Apache Corporation, completed March 28, 2008 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued December 20, 2007, permitted to 10,500 ft.
It was permitted by Mariner Energy, Inc. and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report one formation top, including Wolfcamp.
Its lease has reported 253K barrels of oil and 700K mcf of gas since March 2008, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
