South Keystone /Ellen/ Unit #1064 (API 42-495-01144) is a plugged well in Winkler County, plugged October 9, 2014, last operated by Basin Oil & Gas Operating LLC.
The RRC has issued one drilling permit, issued December 9, 1993, permitted to 10,062 ft.
It was permitted by Pennzoil Petroleum Company and has since transferred to Basin Oil & Gas Operating LLC on the wellbore schedule.
Its 2 leases have reported 1.81M barrels of oil and 13.7M mcf of gas since January 1993, last reporting in July 2026. The leases carry 79 wells, so these are lease totals, not this well alone.
