East Keystone (San A Holt Unit) #1 (API 42-495-30294) is a well in Winkler County operated by Formentera Operations LLC, completed January 20, 1998 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 11, 1997, permitted to 5,240 ft.

It was permitted by Hallwood Petroleum, Inc. and has since transferred to Formentera Operations LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Yates, Colby, Queen, Grayburg.

Its 4 leases have reported 1.61M barrels of oil and 2.02M mcf of gas since January 1993, last reporting in July 2026. The leases carry 161 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.
