Cnb G 345 #11H (API 42-295-33082) is a horizontal well in Lipscomb County operated by Highmark Energy Operating LLC, completed October 24, 2006 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 18, 2006, permitted to 8,359 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 Checkboard, Cleveland.

Its lease has reported 143K barrels of oil and 931K mcf of gas since July 2006, last reporting volume in April 2026. The lease carries 3 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.
