Keystone Holt Unit #9331 (API 42-495-30904) is a well in Winkler County operated by Basin Oil & Gas Operating LLC, completed January 15, 2023 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 16, 1977, permitted to 5,020 ft.
It was permitted by Gulf Oil Corp. and has since transferred to Basin Oil & Gas Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Rustler, Salado, Tansill, Yates.
Its 2 leases have reported 8.74M barrels of oil and 16.3M mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The leases carry 304 wells, so these are lease totals, not this well alone.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
