  • Petrophysical method for predicting shear strength anisotropy in fine-grained rock formations
    Patent number: 9465140
    Abstract: Method and system is described for modeling one or more geophysical properties of a subsurface volume. In one example, a method for predicting strength anisotropy in subsurface formations along a wellpath comprises receiving a stress model of the subsurface formation in the area of the wellpath. Bulk strength properties of target rock are obtained and used to develop anisotropic failure criteria. The stress model may then be combined with the anisotropic failure criteria to develop an anisotropic wellbore stability model which is used to enhance hydrocarbon recovery.
    Type: Grant
