UL Montgomery 1003-21 #1H (API 42-495-34028) is a horizontal well in Winkler County operated by Wpx Energy Permian LLC, completed March 31, 2018 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 3, 2018, permitted to 14,000 ft.

It was permitted by Felix Energy Holdings II, LLC and has since transferred to Wpx Energy Permian LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Rustler, Delaware, Clear Fork, Colby-Queen.

Its lease has reported 1.79M barrels of oil and 2.22M mcf of gas since March 2018, last reporting in July 2026. The lease carries 6 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.
