Abstract

Complex conductivity in shaly sands is interpreted in terms of in-phase and quadrature elements. The model relates the in-phase conductivity of shaly sands to the brine conductivity, water saturation, and clay counterion concentration per unit volume of water present in the pores of the sandstone. The model has been extended to account for the effects of shaliness, brine conductivity and oil saturation on the reactive part of the electrical conductivity. Several aspects of the theory have been verified experimentally.
