WELL · 42-185-30233 · DISTRICT 3
Tucker T.H. Unit #1
Grimes County · Carlton Speed (Wilcox 11800) field · Vertical
Tucker T.H. Unit #1 (API 42-185-30233) is a well in Grimes County operated by High Chapparal Oil Company, completed October 3, 1985.
The RRC has issued 4 drilling permits between 1979 and 2025, permitted to 21,000 ft.
It was permitted by Galloway Energy CO. and has since transferred to High Chapparal Oil Company on the wellbore schedule.
Completion filings report 3 formation tops, including Yegua, Cockfield, Wilcox.
Its 3 leases have reported 115 barrels of oil and 339K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
