Hildreth Jack -B- #4 (API 42-337-31941) is a well in Montague County operated by Crest Operating Company, completed December 24, 2014 and listed as injection on the RRC schedule.
The RRC has issued 2 drilling permits between 1982 and 2014, permitted to 7,450 ft.
It was permitted by Clearfork Production, LLC and has since transferred to Crest Operating Company on the wellbore schedule.

Its lease has reported 61.3K barrels of oil and 123 mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 553K barrels injected in the 12 months reported through July 2025.
