Title:
Mercury Injection Capillary Pressure results from outcrop samples in the Homer area of Cook Inlet
Abstract:
The Alaska Division of Geological & Geological Surveys (DGGS) personnel collected rock samples while conducting stratigraphic studies in the Beluga and Sterling Fomrations in the Homer area of Cook Inlet.Funding for this stratigraphic work was provided by Benchmark Oil and Gas, Pioneer Natural Resources, Chevron North American Exploration and production Company, and the State of Alaska.This data set conveys information about samples collected during fieldwork in the Homer area of Cook Inlet.Samples were collected from outcrops for Mercury Injection Capillary Pressure (MICP) analyses.Analytical data from these rock samples are tabulated in this publication.
Supplemental_Information:
The data are available in tabular format as comma delimited ASCII files organized into four entities as described in this metadata file under the "Entity_and_Attribute_Information" section.The tables are as follows: 
Table_1		summarizes sample name, formation from which the samples were collected, coordinates of sample location, and brief description of MICP samples
Table_2		summary of pore system and capillary properties for Mercury Injection Capillary Pressure analyses
Table_3		summary height data for Mercury Injection Capillary Pressure analyses.
MICP_Raw_Data	summarizes the raw data for Mercury Injection Capillary Pressure samples, composed of tables 4-17.
