Abstract: Homogeneous isotropic or vertically transverse isotropic rocks containing a single set of aligned, vertical fractures exhibits an effective long-wavelength horizontally transverse isotropy (HTI) or orthorhombic anisotropy. The estimation for properties of subsurface fractures has significant… read more here.
