Frost Bank Unit #22H (API 42-311-35933) is a horizontal well in Mcmullen County operated by Verdun Oil EF II LLC, completed September 8, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued March 31, 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 12 formation tops, including Carrizo, Austin Chalk, Eagle Ford, Anacacho.

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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
