Abstract

This paper describes measurements of the complex conductivity of typical sandstones with different clay counterions. That the electrical conductivity of shaly sands is a complex quantity with a reactive as well as a resistive component is well known: the out-of-phase or quadrature conductivity at low frequencies is frequently referred to as induced polarization (IP). The effects of clay counterion type on complex conductivities of shaly sands were studied for the Na** plus , Li** plus , K** plus , Ca** plus ** plus and (C//2H//5)//4N** plus ions. The results are treated in terms of the Waxman-Smits in-phase conductivity equation and a new relation describing the quadrature conductivity.
