Terry County · Prentice (6700) field · Producing · Vertical
Prentice Northeast Unit #558 (API 42-445-31983) is a well in Terry County operated by Highmark Energy Operating LLC, completed June 10, 2008 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 2002 and 2004, permitted to 8,401 ft.
It was permitted by Xto Energy Inc. and has since transferred to Highmark Energy Operating LLC on the wellbore schedule.
Completion filings report 7 formation tops, including Yates, San Andres, Grayburg, Glorieta.
Its 2 leases have reported 27.6M barrels of oil and 6.52M mcf of gas since January 1993, last reporting in July 2026. The leases carry 622 wells, so these are lease totals, not this well alone.
