East Keystone (San A Holt Unit) #1 (API 42-495-32734) is a well in Winkler County operated by Formentera Operations LLC, completed March 23, 2003 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued August 5, 1998, permitted to 5,450 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 1.57M barrels of oil and 1.94M mcf of gas since September 1999, last reporting in July 2026. The leases carry 158 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 18.3K barrels injected in the 12 months reported through August 2025.
