Mitchell County · Coleman Ranch field · Producing · Vertical
Coleman Ranch Unit #503 (API 42-335-31407) is a well in Mitchell County operated by Americo Energy Resources LLC, completed January 24, 1979 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 25, 1978, permitted to 3,384 ft.
It was permitted by American Petrofina CO. Of Tex. and has since transferred to Americo Energy Resources LLC on the wellbore schedule.
Its lease has reported 3.81M barrels of oil and 126K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 145 wells, so these are lease totals, not this well alone.
