Wheeler C.O. #4
Winkler County · Wheeler (Wolfcamp) field · Shut In · Vertical
Wheeler C.O. #4 (API 42-495-05739) is a well in Winkler County operated by Formentera Operations LLC, completed May 22, 2017 and listed as shut in on the RRC schedule, shut in May 1, 2017.
The RRC has issued 2 drilling permits between 1980 and 2008, permitted to 9,320 ft.
It was permitted by Apache Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Devonian, Silurian (undifferentiated), Ellenburger.
Its 2 leases have reported 116K barrels of oil and 852K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
