Best-Huth Unit #1H
Karnes County · Eagleville (Eagle Ford-2) field · Temp Abandoned · Horizontal
Best-Huth Unit #1H (API 42-255-31890) is a horizontal well in Karnes County operated by Marathon Oil EF LLC, completed November 29, 2023 and listed as temp abandoned on the RRC schedule, shut in September 1, 2025.
The RRC has issued one drilling permit, issued March 9, 2011, permitted to 11,556 ft.
It was permitted by Hilcorp Energy Company and has since transferred to Marathon Oil EF LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.
Its 2 leases have reported 976K barrels of oil and 1.56M mcf of gas since June 2011, last reporting volume in April 2026. The leases carry 6 wells, so these are lease totals, not this well alone.
