Tubb J. B. -D- #11 (API 42-103-35032) is a well in Crane County operated by Formentera Operations LLC, completed May 2, 2005 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued September 23, 2004, permitted to 4,700 ft.

It was permitted by Aspen Operating Company, L.L.C. and has since transferred to Formentera Operations LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Judkins, McKnight, Mcnight, Tubb.

Its 2 leases have reported 95.2K barrels of oil and 1.04M mcf of gas since January 1993, last reporting in July 2026. The leases carry 11 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
