Estimating porosity of partially saturated sediments
Abstract The electrical resistivity of an unconsolidated sediment, depends, among other factors, on the fraction of the pore space that is filled with fluid. An empirical relation can be formed that relates measured resistivity and fluid content to the percent saturation. The formula is applied to a core taken from a freshwater lake, and the volume of gas in the sediment is estimated to a depth of 6 m into the lake bottom. The procedures described can lead to improved estimates of porosity and bulk density.
