Prentice Northeast Unit #546 (API 42-445-31816) is a plugged well in Terry County, plugged April 11, 2025, last operated by Highmark Energy Operating LLC.
The RRC has issued one drilling permit, issued May 9, 1997, permitted to 7,400 ft.
It was permitted by Cross Timbers Operating Company and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including Rustler, Yates, San Andres, Glorieta.
Its lease has reported 27.6M barrels of oil and 6.52M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 621 wells, so these are lease totals, not this well alone.

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