Upton County · Spraberry (Trend Area) field · Shut IN · Vertical
Cowden D #4 (API 42-461-36929) is a well in Upton County operated by Apache Corporation, completed October 29, 2010 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued August 24, 2010, permitted to 11,000 ft.
It was permitted by Mariner Energy, Inc. and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 4 formation tops, including Spraberry, Dean, Wolfcamp, Cline.
Its lease has reported 137K barrels of oil and 328K mcf of gas since April 2010, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
