Pieces of rock in each sample were examined using a reflected light microscope (magnifications of 5X to 50X) and a brief description of the rock properties was made (see below). A representative portion of the bulk sample was selected for capillary pressure analysis and trimmed to a size that would fit the sample holder. The sample was then placed in a low temperature convection oven and dried to a constant weight. The high-pressure, mercury injection capillary pressure (MICP) analysis was carried out using a Micromeritics 9420 mercury porosimeter. Penetrometers with 15 cc sample chambers were used for all analyses. Each test utilized a pressure table containing 118 separate pressure points from 1.5 to 59,500 psia, and the volume of mercury injected was measured at each point. The collected data were corrected for closure; that is, intrusion related only to the mercury conforming to the sample surface. Porosity and permeability values were generated for each of the samples using the MICP data. The porosity was measured using an Archimedes bulk volume and the pore volume based on the closure corrected volume of mercury injected. Permeability was calculated using the Swanson Equation (Swanson, 1981).\r\n Swanson (1981)\r\n\t\tVarva and others (1992)\r\n\t\t2009\r\n \r\n \r\n \r\n \r\n Point\r\n \r\n \r\n \r\n \r\n 0.00001\r\n 0.00001\r\n Decimal degrees\r\n \r\n \r\n North American Datum of 1927\r\n Clarke 1866\r\n 6378137\r\n 298.25722210088\r\n \r\n \r\n \r\n \r\n \r\n \r\n sample locations\r\n Table_1.csv\r\n Table 1 is a summary of samples collected in the Homer area of Cook Inlet for Mercury Injection Capillary Pressure analysis.
