Cotulla East Unit #10H (API 42-283-35393) is a horizontal well in La Salle County operated by Verdun Oil EF II LLC, completed August 18, 2015 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued March 6, 2015, permitted to 8,226 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 Wilcox, Escondido, Olmos, Austin Chalk.
Its lease has reported 500K barrels of oil and 1.4M mcf of gas since June 2015, last reporting volume in April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
