Pembrook Unit #8305
Upton County · Spraberry (Trend Area) field · Shut In · Vertical
Pembrook Unit #8305 (API 42-461-33074) is a well in Upton County operated by Pioneer Natural Res. USA Inc., completed April 15, 1991 and listed as shut in on the RRC schedule, shut in February 1, 2025.
The RRC has issued one drilling permit, issued October 22, 1990, permitted to 8,115 ft.
It was permitted by Exxon Corp. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 2 formation tops, including Clear Fork, Spraberry.
Its lease has reported 21.6M barrels of oil and 42.8M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 334 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
