Coffield H.H. Estate #3T (API 42-331-32507) is a plugged well in Milam County, plugged July 20, 2005, last operated by Sierra Minerals Inc..
The RRC has issued one drilling permit, issued January 5, 1984, permitted to 1,600 ft.
It was permitted by Triple-S Ventures, Inc. and has since transferred to Sierra Minerals Inc. on the wellbore schedule.
Completion filings report one formation top, including Navarro.
Its lease has reported 55 barrels of oil and 21 mcf of gas since January 1993, last reporting in March 2008. The lease carries 2 wells, so these are lease totals, not this well alone.
