Colbert Jack #4 (API 42-331-35013) is a well in Milam County operated by Speckle Trout Operating LLC, completed March 21, 2018 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 18, 2018, permitted to 2,500 ft.

It was permitted by Dpm Operating and has since transferred to Speckle Trout Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Wilcox, Edwards, Navarro.

Its lease has reported 73.8K barrels of oil and 6.15K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
