Prentice Northeast Unit #148 (API 42-445-30846) is a well in Terry County operated by Highmark Energy Operating LLC, completed February 17, 2007.

The RRC has issued 2 drilling permits between 1980 and 2007, permitted to 7,500 ft.

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

Completion filings report 2 formation tops, including Glorieta, Clear Fork.

Its lease has reported 27.6M barrels of oil and 6.52M mcf of gas since January 1993, last reporting in July 2026. The lease carries 621 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 160K barrels injected in the 12 months reported through November 2025.

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