East Keystone (San A Holt Unit) #1 (API 42-495-32575) is a well in Winkler County operated by Formentera Operations LLC, completed July 31, 2002 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued September 4, 1996, permitted to 5,350 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 2.05M mcf of gas since October 1996, 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 107K barrels injected in the 12 months reported through August 2025.

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