Cnb Trustees 360 #4H (API 42-295-33490) is a horizontal well in Lipscomb County operated by Highmark Energy Operating LLC, completed January 19, 2010 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued December 22, 2008, permitted to 9,000 ft.

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

Completion filings report 2 formation tops, including Checkerboard Ls, Cleveland.

Its lease has reported 209K barrels of oil and 2.2M mcf of gas since January 2004, last reporting in July 2026. The lease carries 4 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.
