Among those technologies such as shear wave exploration, P-S converted waves, multi-component seismic, VSP, P-wave AVA, AVO, AVOZ and VVA, the most effective method in detecting fractures is shear-wave splitting.

First model brings three component syn-thetic seismograms which show obvious shear wave splitting and clear P-SH wavein Y component.

Themodel offers definite physical background and mathematic description in multicomponent data processing under anisotropy medium condition,and it unifies most ex-isting ordinary shear wave splitting algorithms which are used to compute both po-larizing angle of shear wave splitting and moveouts between fast wave and slowwave.
