Tubb J. B. A/C 1 #236 (API 42-103-32399) is a well in Crane County operated by Formentera Operations LLC, completed December 17, 1980 and listed as shut in on the RRC schedule, shut in November 1, 2018.

The RRC has issued 3 drilling permits between 1980 and 2006, permitted to 4,715 ft.

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

Its 2 leases have reported 2.52M barrels of oil and 41.2M mcf of gas since January 1993, last reporting volume in April 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.
