Abstract
A new theoretical model has been developed for transient controlled-source electromagnetic (CSEM) exploration of multi-layer aquifers. The method is applicable to fractured rock and other types of lithology which exhibit length-scale dependent heterogenity. A roughness parameter β is used, in the present paper, as a proxy for fracture density.
