Tubb-State J.B. #20 (API 42-103-33747) is a well in Crane County operated by Blackbeard Operating LLC, completed March 8, 2010 and listed as producing on the RRC schedule.

The RRC has issued 2 drilling permits between 1985 and 2010, permitted to 4,650 ft.

It was permitted by Cimarex Energy CO. Of Colorado and has since transferred to Blackbeard Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Judkins, McKnight, Tubb.

Its lease has reported 267K barrels of oil and 2.1M mcf of gas since January 1993, last reporting in July 2026. The lease carries 18 wells, so these are lease totals, not this well alone.
