Equivalent Offset Migration (EOM) was proposed to have both advantages of the conventional post-stack processing and velocity analysis as an alternative method to partial prestack migration, and draw attention in exploration geophysics for its computational efficiency and imaging accuracy. In the conventional EOM, it is mainly to use the vertical component of received waveforms, not horizontal components. However, it is necessary to get S-wave velocity structure in order to establish the sub-surface model including petrophysical properties. Thus, we conduct numerical experiments to verify the possibility of extracting information about S-wave velocity structure using EOM with the horizontal components. Our numerical results show that EOM based on the horizontal components can increase the amount of information of S-wave velocity whereas some unique difficulties to the horizontal components should be addressed.
