Tubb J. B. A/C 1 #151L (API 42-103-31819) is a permitted well in Crane County filed by Exxon Corp.; no completion report is on file yet.
The RRC has issued 2 drilling permits (amended once) between 1978 and 1994, permitted to 4,490 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 Judkins, Tubb.
Its 2 leases have reported 1.26M barrels of oil and 18.7M 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.
Operator of record

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.
Wells nearby
Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
