Fracture basement is one of the potential targets for hydrocarbon traps. The properties of the fractures are hardly known in complex geological setting. The emphasis of this study is on the possible use of shear wave splitting in fractured or anisotropic media to obtain the most significant parameters. To perform this technique, cross-correlation method is employed in the three-component (3C) seismic data. This approach estimates the (1) time delay (dt) between the slow and fast waves which gives the crack density in the medium, (2) fast polarization direction (?), offering the fracture orientation and correlation between slow and fast component. Here, we present three case studies on shear wave measurements and the results conclude that shear wave splitting is a reliable method to determine the fracture orientation and density.
