Tubb J B A/C 1 #251 (API 42-103-32671) is a well in Crane County operated by Formentera Operations LLC, completed February 20, 1996 and listed as producing on the RRC schedule.

The RRC has issued 3 drilling permits between 1981 and 1995, permitted to 4,797 ft.

It was permitted by Exxon Corp. and has since transferred to Formentera Operations LLC on the wellbore schedule.

Its 2 leases have reported 1.26M barrels of oil and 19.4M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 172 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.
