Modal analyses and routine core analyses were performed on Tertiary and Mesozoic siltstones and sandstones collected during the 2007-2010 field seasons from six geographic areas in upper and lower Cook Inlet. The reservoir quality of Cook Inlet sandstones varies widely depending on their mineralogy, geologic age, burial depth, and depositional environment. Tuxedni and Naknek sandstones have poor reservoir quality and are likely to be of equally poor quality down dip. West Foreland sandstones examined have poor reservoir quality and are negatively influenced by their immature volcanic mineralogy. The Hemlock and Tyonek sandstones have good to excellent reservoir quality, largely resulting from their quartzose-feldspathic mineralogy that is physically and chemically stable and burial depths generally less than 3,000 m. It should be emphasized that our observations are based on a limited number of outcrop samples collected from widely dispersed localities. Purpose: The State of Alaska Division of Geological & Geophysical Surveys (DGGS) and Division of Oil & Gas (DOG) are currently engaged in a multi-year study of the hydrocarbon potential of the Tertiary and Mesozoic strata in Cook Inlet basin. This report presents petrographic and routine core-analysis data and provides preliminary interpretations of rock samples. The samples were collected from Tertiary sections on the Kenai Peninsula from Homer northward to Clam Gulch, Tertiary sections on the west side of Cook Inlet from Lewis River westward to Straight Creek, and sections of Mesozoic strata in lower Cook Inlet along the shores of Tuxedni Bay and the Iniskin Peninsula. Supplemental_Information: The DGGS metadata standard extends the FGDC standard to include elements that are required to facilitate our internal data management.

Lineage: Process_Step: Process_Description: Sample collection and geologic formation assignment - Tertiary and Mesozoic siltstones and sandstones from six geographic areas in the upper and lower Cook Inlet were collected during the 2007-2010 field seasons. Initial formation assignment for each sample was based on previously published maps and ongoing DGGS/DOG fieldwork in the area. In some cases assignments were modified after the modal data were analyzed to ensure petrographically similar samples were included in the same unit. After much experimentation a procedure was developed to acquire usable samples that could be plugged for analysis. This entailed excavating large "bread-loaf" sized samples that were immediately wrapped in several layers of plastic wrap and secured in canvas bags with duct tape. These samples were later placed in plastic bags and covered with a thin coating of epoxy resin prior to shipping. Process_Date: 2007-2010 Process_Step: Process_Description: Modal analysis - Samples were submitted to Michael D. Wilson, a geological consultant in Lakewood, CO, for modal analysis. He counted a minimum of 300 grains via the traditional point-counting method (Decker and Helmold, 1985) to determine the composition of the framework (detrital grains) and intergranular components (matrix, cement, porosity). A second count of 200 grains (including matrix) was conducted for grain size. Process_Date: 2011 Process_Step: Process_Description: Routine core analysis - Samples were submitted to Weatherford Labs, Inc. for routine core analysis to determine porosity and permeability. Process_Date: 2011 Process_Step: Process_Description: Data interpretation - Modal analysis and porosity and permeability datasets were plotted and examined to provide a preliminary interpretation of the petrology and reservoir potential of the rock units. See manuscript for more information about the interpretive process and results. The manuscript also provides a detailed list of pertinent references.
