McMullen County · Eagleville (Eagle Ford-1) field · Producing · Horizontal
Frost Bank Unit #104H (API 42-311-36863) is a horizontal well in Mcmullen County operated by Verdun Oil EF II LLC, completed November 28, 2018 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 17, 2018, permitted to 11,000 ft.
It was permitted by EP Energy E&P Company, L.P. and has since transferred to Verdun Oil EF II LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Yegua, Wilcox, Escondido, Olmos.
Its lease has reported 1.04M barrels of oil and 753K mcf of gas since July 2014, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.
