Ector County · Goldsmith (Clear Fork) field · Shut In · Vertical
Cowden Clyde #128 (API 42-135-02584) is a well in Ector County operated by Maverick Permian LLC, completed October 12, 2011 and listed as shut in on the RRC schedule, shut in March 1, 2023.
The RRC has issued one drilling permit, issued November 3, 1989, permitted to 5,902 ft.
It was permitted by Phillips Petroleum Company and has since transferred to Maverick Permian LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Rustler, Yates, San Andres, Holt.
Its 2 leases have reported 7.38M barrels of oil and 11.9M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 261 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
