Studley Cko West A 29-22 #4201H (API 42-383-41404) is a horizontal well in Reagan County operated by De Central Operating LLC, completed January 10, 2024 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued June 2, 2023, permitted to 10,605 ft.

It was permitted by De IV Operating, LLC and has since transferred to De Central Operating LLC on the wellbore schedule.

Completion filings report 8 formation tops, including Queen, Grayburg, San Andres, Clear Fork.

Its lease has reported 415K barrels of oil and 2.39M mcf of gas since August 2023, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
