East Keystone (San A Holt Unit) #1 (API 42-495-05254) is a plugged well in Winkler County, plugged July 25, 2019, last operated by Formentera Operations LLC.
The RRC has issued one drilling permit, issued March 28, 1995, permitted to 5,500 ft.
It was permitted by Hallwood Petroleum, Inc. and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 2 formation tops, including San Andres, Holt.
Its 4 leases have reported 1.68M barrels of oil and 2.16M mcf of gas since January 1993, last reporting in July 2026. The leases carry 167 wells, so these are lease totals, not this well alone.
