Tubb J. B. A/C #2 #314 (API 42-103-35225) is a well in Crane County operated by Formentera Operations LLC, completed July 5, 2006 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 15, 2006, permitted to 3,700 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, San Angelo.
Its 2 leases have reported 1.34M barrels of oil and 23.3M mcf of gas since January 1993, last reporting in July 2026. The leases carry 179 wells, so these are lease totals, not this well alone.
