Description

Raw Data File 2021-13, Qualitative assessment of composition and reservoir quality of Albian-Cenomanian Nanushuk Formation sandstones, measured outcrop sections, central North Slope, Alaska, presents a qualitative appraisal of thin sections collected from Nanushuk outcrops to ascertain their reservoir potential. The DGGS sample collection was searched for petrographic thin sections collected from stratigraphic sections of the Nanushuk Formation measured by David LePain working with various colleagues, including Russ Kirkham, Paul Decker, Dave Houseknecht, and Nina Harun over the past 22 years. The search yielded 264 thin sections of Nanushuk siltstone and sandstone. Three additional thin sections of the Seabee Formation mudstone, siltstone, and sandstone were collected from the upper portion of a measured section that straddles the Nanushuk - Seabee contact. These 267 samples were collected from 32 stations located in eight geographic areas on the North Slope, including Slope Mountain, May Creek, Arc Mountain, Rooftop Ridge, Big Bend of the Chandler River, Ninuluk Bluff on the Colville River, Killik Bend of the Colville River, and Horseshoe Bend of the Colville River. The thin sections were examined qualitatively to ascertain several petrographic properties, including grain size, detrital composition, cement and matrix content, the abundance of burrows and laminations, and porosity distribution. Sedimentary structures observed in the field were noted, as was the interpreted sedimentary facies association. The results are compiled in a spreadsheet along with information on geographic location, latitude, longitude, and measured petrophysical properties (porosity, permeability, and grain density) of the few samples where available.
