Tubb J. B. A/C #1 #263 (API 42-103-32897) is a well in Crane County operated by Formentera Operations LLC, completed May 16, 2007 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits (amended once) between 1982 and 2007, permitted to 4,836 ft.
It was permitted by Apache Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Judkins, McKnight, Tubb.
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.

Well logs
1 log loaded from the RRC's log index, the latest received Aug 13, 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.
