Abstract
Utilizing the interrelationship between elastic anisotropy parameters, which is inherent in the common texture of clay-rich shales offers opportunities to apply anisotropic models to field studies where anisotropic input data are lacking.
This is of operational relevance for borehole stability, hydraulic fracturing and geomechanical modelling of overburden stress and pore pressure changes due to depletion or injection.
The level of sophistication can easily be increased: For instance, the non-clay component could be simulated by using a separate rock physics model. However, increased reliability also demands more and reliable input data.
