Barnhart (EF) J #2H (API 42-177-33148) is a horizontal well in Gonzales County operated by Ensign Natural Resources II LLC, completed January 9, 2021 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued September 27, 2013, permitted to 12,021 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 1.27M barrels of oil and 2.63M mcf of gas since November 2013, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
