Barnhart (EF) #7H (API 42-177-32494) is a horizontal well in Gonzales County operated by Marathon Oil EF LLC, completed August 27, 2012 and listed as shut in on the RRC schedule.

The RRC has issued 2 drilling permits between 2012 and 2026, permitted to 14,800 ft.

It was permitted by Ensign Natural Resources II LLC 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 lease has reported 15M barrels of oil and 18.4M mcf of gas since November 2010, last reporting in July 2026. The lease carries 60 wells, so these are lease totals, not this well alone.
