Cowden 10 #4H (API 42-103-36295) is a horizontal well in Crane County operated by Formentera Operations LLC, completed March 8, 2015 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 27, 2014, permitted to 3,500 ft.

It was permitted by Apache Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Permian (undifferentiated), Rustler, Yates, Queen.

Its lease has reported 245K barrels of oil and 557K mcf of gas since August 2013, last reporting in July 2026. The lease carries 3 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.
