Pembrook Unit #8219 (API 42-461-33082) is a plugged well in Upton County, plugged December 17, 1997, last operated by Pioneer Natural Res. USA Inc..
The RRC has issued one drilling permit, issued November 5, 1990, permitted to 8,500 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.
