Prentice Northeast Unit #510 (API 42-445-32012) is a well in Terry County operated by Highmark Energy Operating LLC, completed May 23, 2003 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued February 20, 2003, permitted to 7,387 ft.

It was permitted by Xto Energy Inc. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Rustler, San Andres, T. Glorieta, T. Clearfork.

Its lease has reported 27.7M barrels of oil and 6.55M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 621 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.
