Ector County · Cowden South field · Shut In · Horizontal · Sidetrack
South Cowden Unit #623 (API 42-135-36941) is a horizontal well in Ector County operated by Conocophillips Company, completed April 21, 2000 and listed as shut in on the RRC schedule, shut in February 1, 2025.
The RRC has issued 3 drilling permits between 1994 and 2000, permitted to 4,900 ft.
It was permitted by Phillips Petroleum Company and has since transferred to Conocophillips Company on the wellbore schedule.
Completion filings report 4 formation tops, including Yates, Queen, Grayburg, San Andres.
Its lease has reported 3.52M barrels of oil and 11.8M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 118 wells, so these are lease totals, not this well alone.
