The Kukpowruk River cuts through folded Cretaceous rocks in the central North Slope. These rocks were assessed by the USGS in 2017 and lie above the rocks assessed in the USGS 2021 Western North Slope assessment.

Jurassic rocks exposed in thurst-faulted structures near the southern limit of Western North Slope. In the subsurface farther north, these rocks may be reservoir rocks for natural gas.

Bedding features in the core from the USGS Gulf Coast #4 Bonham borehole, in the Eagle Ford Group mudstones from a depth of about 401 feet, Fannin County, Texas. The Eagle Ford Group lies underneath the Austin Chalk and serves as the source rock for much of the Austin Chalk's petroleum.

Geologist examines f Faulted and folded petroleum source rocks in Jurassic and Cretaceous rocks (Kingak Shale, pebble shale unit, and gamma-ray zone of Hue Shale) in southern part of Western North Slope. Thermal maturity of these rocks is at the upper limit of oil preservations.
