A New Model to Describe the Spectral Induced Polarization (SIP) of Sedimentary Rocks

P057 A NEW MODEL TO DESCRIBE THE SPECTRAL INDUCED POLARIZATION (SIP) OF SEDIMENTARY ROCKS Summary 1 The capillary network model (CNM) which describes the frequency dependent electrical resistivity of water saturated sedimentary rocks is introduced. The model enables us to calculate the spectral induced polarization (SIP) response from pore radius distributions and vice versa. Thus the model offers the possibility to obtain the pore radius distribution from SIP measurements. It seems to be possible to predict the hydraulic permeability using SIP measurements. Introduction Up to now the causes of the induced polarization (IP) of sedimentary rocks were mainly described qualitatively.
