Midland County · Spraberry (Trend Area) field · Shut IN · Vertical
Peck 21 #4 (API 42-329-35519) is a well in Midland County operated by Apache Corporation, completed September 29, 2006 and listed as shut in on the RRC schedule.
The RRC has issued 2 drilling permits between 2006 and 2018, permitted to 12,000 ft.
It was permitted by Endeavor Energy Resources L.P. and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 7 formation tops, including Yates, San Andres, Spraberry, Dean.
Its lease has reported 187K barrels of oil and 531K mcf of gas since May 2004, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
