East Keystone (San A Holt Unit) #317 (API 42-495-30399) is a plugged well in Winkler County, plugged July 20, 2019, last operated by Formentera Operations LLC.
The RRC has issued one drilling permit, issued December 22, 1995, permitted to 5,600 ft.
It was permitted by Vista Resources, Inc. (A) and has since transferred to Formentera Operations LLC on the wellbore schedule.
Its 3 leases have reported 2.05M barrels of oil and 3.05M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 187 wells, so these are lease totals, not this well alone.
