Contribution of stern layer and membrane polarization to the spectral induced polarization of porous media

Rossi, M. LU ; Brovelli, A. ; Cassiani, G. ; Johansson, S. LU and Dahlin, T. LU orcid (2017) 23rd European Meeting of Environmental and Engineering Geophysics
Abstract

Recently there is an increasing interest in the understanding of the Spectral Induced Polarization (SIP) phenomenon in porous media. The complex electrical conductivity of porous geological materials has a frequency dependent behavior than can be associated to three main mechanisms: Maxwell-Wagner (MW) polarization, Membrane polarization, Electrical double layer (EDL) polarization. This paper aims to develop a mechanistic model for induced polarization in frequency domain, that incorporates both grain and membrane polarization and uses a non-linear mixing rule to combine the contribution of water, air and solid grains. The model is tested on two different lab experimental datasets. Different spectra characteristics can be understood and... (More)

This paper aims to develop a mechanistic model for induced polarization in frequency domain, that incorporates both grain and membrane polarization and uses a non-linear mixing rule to combine the contribution of water, air and solid grains. The model is tested on two different lab experimental datasets. Different spectra characteristics can be understood and described by distinguished porous media behaviors.
