Prentice Northeast Unit #35 (API 42-445-00299) is a well in Terry County operated by Highmark Energy Operating LLC, completed November 10, 1985.

The RRC has issued one drilling permit, issued August 12, 2002, permitted to 6,750 ft.

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

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.

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