Not one formation; the well must be completed in one of them, and no target formation is stated. The district's wildcat field is also on the permit.

Cowden Clyde #178 (API 42-135-36128) is a well in Ector County operated by Maverick Permian LLC, completed May 29, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued September 7, 1989, permitted to 6,680 ft.

It was permitted by Phillips Petroleum Company and has since transferred to Maverick Permian LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Yates, San Andres, Glorieta, Clear Fork.

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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
