Pembrook Unit #405 (API 42-461-33078) is a plugged well in Upton County, plugged January 24, 2019, last operated by Pioneer Natural Res. USA Inc..

The RRC has issued one drilling permit, issued October 24, 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.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
