Welch Trust 8-7-E #4309H (API 42-383-40357) is a horizontal well in Reagan County operated by Pioneer Natural Res. USA Inc., completed March 6, 2019 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued July 23, 2018, permitted to 8,935 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 10 formation tops, including San Andres, Clear Fork, Spraberry, Dean.

Its lease has reported 852K barrels of oil and 3.83M mcf of gas since March 2019, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
