Colbert Jack #1 (API 42-331-32531) is a plugged well in Milam County, plugged May 29, 2002, last operated by Speckle Trout Operating LLC.

The RRC has issued one drilling permit, issued March 2, 1984, permitted to 3,250 ft.

It was permitted by Heartland Resources, Inc. and has since transferred to Speckle Trout Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Base Of The Wilcox, Wilcox, 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.
