Barnhart (EF) C #3H (API 42-177-32763) is a horizontal well in Gonzales County operated by Ensign Natural Resources II LLC, completed May 10, 2014 and listed as producing on the RRC schedule, shut in December 1, 2024.

The RRC has issued one drilling permit (amended once), issued November 5, 2012, permitted to 11,761 ft.

It was permitted by Marathon Oil EF LLC and has since transferred to Ensign Natural Resources II LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.

Its lease has reported 1.21M barrels of oil and 2.21M mcf of gas since November 2012, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
