Jeffery Est. B #1B (API 42-503-39945) is a well in Young County operated by Four Corners Energy LLC, completed March 29, 1989 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued January 25, 1989, permitted to 4,999 ft.

It was permitted by Chital Petroleum Corp. and has since transferred to Four Corners Energy LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Caddo, Barnett, Mississippian.

Its lease has reported 14.2K barrels of oil and 19 mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
