Maltsberger #25H (API 42-283-33255) is a horizontal well in La Salle County operated by Verdun Oil EF II LLC, completed January 3, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 22, 2012, permitted to 11,400 ft.

It was permitted by El Paso E & P Company, L. P. and has since transferred to Verdun Oil EF II LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Ancc, Astn, Egfd.

Its lease has reported 3.51M barrels of oil and 6.86M mcf of gas since December 2010, last reporting in July 2026. The lease carries 42 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.
