East Keystone (San A Holt Unit) #1 (API 42-495-32532) is a plugged well in Winkler County, plugged June 7, 2023, last operated by Formentera Operations LLC.

The RRC has issued 2 drilling permits (amended once) between 1996 and 1999, 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 1.59M barrels of oil and 2M mcf of gas since April 1996, last reporting in July 2026. The leases carry 158 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
