Modelling The Electrical Properties Of Porous Rocks And Soils Containing Immiscible Contaminants

Inclusion-based models are used to describe porous rocks and soils containing<br>immiscible contaminants. The results of modelling show that the functional relationship<br>between dielectric properties and the level of fluid saturation can vary significantly as the<br>pore-scale fluid distribution changes in terms of both the geometrical configuration and the<br>choice of wetting phase. The magnitude of these variations increases with decreasing<br>measurement frequency, indicating that the location of the conductive water phase is<br>important. The low frequency electrical conductivity depends on the connectivity of the<br>water phase. An inclusion-based model is used to compute the electrical stratigraphy of an<br>immiscible contaminant pooled at the water table interface.
