East Keystone (San A Holt Unit) #1 (API 42-495-05299) is a plugged well in Winkler County, plugged July 28, 2020, last operated by Formentera Operations LLC.
The RRC has issued one drilling permit, issued November 7, 1984, permitted to 8,110 ft.
It was permitted by Amoco Production CO.-Andrews and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 3 formation tops, including San Andres, Holt, Devonian.
Its 3 leases have reported 1.61M barrels of oil and 2.03M mcf of gas since January 1993, last reporting in July 2026. The leases carry 161 wells, so these are lease totals, not this well alone.
