Tubb J. B. A/C 1 #233 (API 42-103-32375) is a plugged well in Crane County, plugged March 21, 2001, last operated by Formentera Operations LLC.

The RRC has issued 2 drilling permits in 1980, permitted to 4,775 ft.

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

Its 2 leases have reported 2.52M barrels of oil and 41.3M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The leases carry 325 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.

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