The focus of this study is on shear wave splitting caused by preferential fractures and differential stress. Multicomponentmultisource offshore seismic data events recorded by arrays of three-component (3C) digital seismometers of Malay Basin provides valuable insight into the use of shear-wave splitting (SWS) measurements. The properties of shear wave splitting can be used to infer (1) the directional dependence of polarization (ø) in fractures medium, usually parallel to crack orientation; and (2) the measurement of delay time (δt) between the two split S-waves is proponational to the number of cracks per unit volume with splitting uncertainties. © 2015 SEG.
