Winkler County · Keystone (Consolidated) field · Temp Abandoned · Horizontal · Sidetrack
Keystone Holt Unit #662 (API 42-495-03938) is a horizontal well in Winkler County operated by Basin Oil & Gas Operating LLC, completed December 13, 1998 and listed as temp abandoned on the RRC schedule, shut in July 1, 2020.
The RRC has issued one drilling permit, issued November 30, 1998, permitted to 10,333 ft.
It was permitted by Bass Enterprises Production CO. and has since transferred to Basin Oil & Gas Operating LLC on the wellbore schedule.
Completion filings report 7 formation tops, including Holt, Clear Fork, San Angelo, Wolfcamp.
Its 3 leases have reported 6.68M barrels of oil and 16.3M mcf of gas since January 1993, last reporting in July 2026. The leases carry 206 wells, so these are lease totals, not this well alone.
