Prentice Northeast Unit #42 (API 42-445-00517) is a plugged well in Terry County, plugged November 26, 1997, last operated by Highmark Energy Operating LLC.
The RRC has issued one drilling permit, issued May 10, 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.
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 184K barrels injected in the 12 months reported through November 2025.
