Tubb J. B. A/C 1 #239 (API 42-103-32424) is a well in Crane County operated by Formentera Operations LLC, completed January 22, 1981.
The RRC has issued 3 drilling permits between 1980 and 2007, permitted to 5,000 ft.
It was permitted by Apache Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Judkins, McKnight, San Angelo, Tubb.
Its 2 leases have reported 2.52M barrels of oil and 41.2M mcf of gas since January 1993, last reporting in July 2026. The leases carry 325 wells, so these are lease totals, not this well alone.
