East Keystone (San A Holt Unit) #2 (API 42-495-05256) is a plugged well in Winkler County, plugged November 13, 2018, last operated by Formentera Operations LLC.
The RRC has issued one drilling permit (amended once), issued August 18, 1994, 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 4 formation tops, including Queen, Colby, San Andres, Holt.
Its 3 leases have reported 1.65M barrels of oil and 2.13M mcf of gas since January 1993, last reporting in July 2026. The leases carry 163 wells, so these are lease totals, not this well alone.
