Cnb Trustees 360 #3H (API 42-295-33312) is a plugged horizontal well in Lipscomb County, plugged April 4, 2014, last operated by Highmark Energy Operating LLC.

The RRC has issued one drilling permit, issued April 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 Limestone, Cleveland.

Its 2 leases have reported 209K barrels of oil and 2.2M mcf of gas since January 2004, last reporting in July 2026. The leases carry 5 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.
