University 9-31 #1H (API 42-383-37374) is a horizontal well in Reagan County operated by Permian Resources Operating LLC, completed November 22, 2022 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued July 6, 2011, permitted to 8,310 ft.

It was permitted by Devon Energy Production CO, L.P. and has since transferred to Permian Resources Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.

Its 2 leases have reported 2.24M barrels of oil and 5.08M mcf of gas since October 2011, last reporting volume in April 2026. The leases carry 27 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.

Well logs

1 log loaded from the RRC's log index, the latest received Mar 11, 2013. Density, Neutron. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
