... emphasized that a new seismic inversion tool that can handle anisotropy should be developed. Although Ru¨ger (1997) proposed an AVO equation for P-wave reflection coefficients in a TI media, it can only provide an accurate es- timation based on the assumptions of weak contrast and weak anisotropy...

... Detection of faults especially subtle faults and fractures is a challenging task using conventional seismic data due to the low signal-to-noise ratio. Data conditioning is a first step to use structural attributes because each seismic volume has its own challenges and has different imaging. We...
