Welch Trust 8 #4411H (API 42-461-40250) is a horizontal well in Upton County operated by Pioneer Natural Res. USA Inc., completed February 15, 2016 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued November 20, 2015, permitted to 9,516 ft.
It was permitted by Parsley Energy Operations, LLC and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 9 formation tops, including San Andres, Spraberry, Wolfcamp, Devonian.
Its lease has reported 249K barrels of oil and 873K mcf of gas since November 2014, last reporting volume in April 2026. The lease carries 4 wells, so these are lease totals, not this well alone.

Completion filings
W-2 and G-1 reports on record in the RRC wellbore file, newest first. The suffix identifies the wellbore or completion event. The record date is the RRC's own date on the record, not the day the report was filed: 462,034 of the state's filings carry 1984-01-12. About these reports →

Well logs
1 log loaded from the RRC's log index, 1 of it with a digital LAS file, the latest received Feb 2, 2019. Gamma ray. 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.
