Keystone Holt Unit #9337 (API 42-495-31097) is a well in Winkler County operated by Basin Oil & Gas Operating LLC, completed September 18, 2024 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued September 11, 1979, permitted to 5,040 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 12 formation tops, including Rustler, Salado, Yates, Seven Rivers.

Its 3 leases have reported 8.74M barrels of oil and 17.8M mcf of gas since January 1993, last reporting in July 2026. The leases carry 305 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.
