Gonzales County · Eagleville (Eagle Ford-1) field · Shut In · Horizontal
Barnhart (EF) 2h Unit #4H (API 42-177-32148) is a horizontal well in Gonzales County operated by Ensign Natural Resources II LLC, completed January 29, 2011 and listed as shut in on the RRC schedule, shut in July 1, 2021.
The RRC has issued one drilling permit (amended once), issued December 14, 2010, permitted to 11,900 ft.
It was permitted by Hilcorp Energy Company and has since transferred to Ensign Natural Resources II LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Anacacho, Austin Chalk, Upper Ef, Eagle Ford.
Its 2 leases have reported 15.5M barrels of oil and 19.4M mcf of gas since July 2010, last reporting in July 2026. The leases carry 64 wells, so these are lease totals, not this well alone.
