Parameterization of Biot–Willis Effective-Stress Coefficient for Deformation and Alteration of Porous Rocks

The effective stress coefficient is an essential geomechanical parameter required for estimation of the effective stress acting upon the subsurface reservoir porous rock formations and affecting their petrophysical properties. The values of the effective stress coefficient for various rock properties depend on the complex phenomena involving various types of rock deformation and alteration processes. This paper presents a discussion of the...
