Mellenbruch Unit #10H
LA Salle County · Eagleville (Eagle Ford-1) field · Horizontal
Mellenbruch Unit #10H (API 42-283-35226) is a horizontal well in La Salle County operated by Verdun Oil EF II LLC, completed January 15, 2016.
The RRC has issued one drilling permit (amended 3 times), issued November 10, 2014, permitted to 11,000 ft.
It was permitted by Carrizo (Eagle Ford) LLC and has since transferred to Verdun Oil EF II LLC on the wellbore schedule.
Completion filings report 11 formation tops, including Midway, Escondido, Olmos, Austin Chalk.
Its 2 leases have reported 435K barrels of oil and 1.83M mcf of gas since July 2015, last reporting in July 2026. The leases carry 9 wells, so these are lease totals, not this well alone.
