Welch #1
Reagan County · Spraberry (Trend Area) field · Vertical
Welch #1 (API 42-383-31925) is a plugged well in Reagan County, plugged November 15, 2021, last operated by Pioneer Natural Res. USA Inc..
The RRC has issued 2 drilling permits between 1981 and 1995, permitted to 8,700 ft.
It was permitted by Mewbourne Oil CO. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 4 formation tops, including San Andres, Clear Fork, Spraberry, Dean.
Its 2 leases have reported 74.6K barrels of oil and 297K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 4 wells, so these are lease totals, not this well alone.
