Tubb J. B. -D- #15 (API 42-103-35557) is a well in Crane County operated by Formentera Operations LLC, completed September 12, 2008 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued March 28, 2008, permitted to 6,000 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 lease has reported 95.2K barrels of oil and 1M mcf of gas since January 1993, last reporting in July 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
