Mellenbruch Unit #11H (API 42-283-35227) is a horizontal well in La Salle County operated by Verdun Oil EF II LLC, completed January 15, 2016 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended 3 times), issued November 10, 2014, permitted to 10,139 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 488K barrels of oil and 1.6M mcf of gas since July 2015, last reporting volume in April 2026. The leases carry 9 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.
