CBW is the most key petrophysical parameter and commonly used to calibrate log porosity for shale formation evaluation (Coates et al., 1999).

Inverting for the elastic properties of this interparticle region indicates that its effective bulk modulus is like that of water. However, it has a nonzero effective shear modulus that is smaller by an order of magnitude, consistent with the expected shear modulus of clay-bound ... sick recovery benefit
