The degree of absorption is applied to calculating the material's physical properties such as density, porosity, and also the material's shear strength values at varying depths in terms of cohesion and internal friction angle. Dielectric permittivity is also used to calculate the moisture...

.... However, in the geomechanics and petroleum literature, the permeability change of reservoir formation subjected to deformation changes is usually assumed as a function of porosity or volumetric strain, which is a scalar variable. Thus, the changes in permeability are equal in all directions even though...
