Tubb J. B. A/C 1 #243 (API 42-103-32487) is a plugged well in Crane County, plugged March 12, 1993, last operated by Formentera Operations LLC.

The RRC has issued 2 drilling permits in 1981, permitted to 4,800 ft.

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

Completion filings report 2 formation tops, including McKnight, Tubb.

Its 2 leases have reported 2.52M barrels of oil and 41.2M mcf of gas since the record begins in 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.

Well logs

1 log loaded from the RRC's log index, the latest received Jul 30, 2012. Neutron. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
