... mechanism. The conduction mechanism, in turn, is determined by pore geometry as well as nongeometric factors such as wettability and the presence of conductive or surface conductive minerals. In general, the measured (Resistivity Index) RI curves cannot be described by an Archie's law and the measurements...
