WebPore-Water Salinity: The induced polarization within a rock depends on having a mechanism for accumulating ionic charges. It also depends on the salinity of the pore water; i.e. the concentration of ions within the pore water. As the pore-water salinity increases, so does the capacity of the rock to support a build-up of ionic charges. WebPore throat sizes for a rock can be measured using capillary pressure–mercury injection tests, which can be converted to a distribution or profile of pore throat sizes for a sample. …
