This model allows the three key variables: the volume fractions of dispersed clay ( X d...

Thus, the modeled dielectric dispersion is controlled by a few key petrophysical parameters: the water-filled porosity, the brine salinity, the water phase tortuosity exponents, and the trapped water fraction. Within our model construction, the trapped...
