Not one formation; the well must be completed in one of them, and no target formation is stated. The district's wildcat field is also on the permit.

Prentice Northeast Unit #731 (API 42-445-32113) is a well in Terry County operated by Highmark Energy Operating LLC, completed March 27, 2006 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued February 8, 2006, permitted to 7,386 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 27.7M barrels of oil and 6.55M mcf of gas since the record begins in January 1993, last reporting volume in August 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.

1 log loaded from the RRC's log index, the latest received Jul 12, 2007. Density, Neutron. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
