University East #4H (API 42-235-35069) is a horizontal well in Irion County operated by Rrp Operating LLC, completed February 1, 2017 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued May 29, 2012, permitted to 12,990 ft.

It was permitted by EP Energy E&P Company, L.P. and has since transferred to Rrp Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Dean, Wfmpb, Wolfcamp, Wfmpb1.

Its lease has reported 19.7M barrels of oil and 220M mcf of gas since October 2011, last reporting in July 2026. The lease carries 236 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.
