[STT17-01] Elastic imaging of subsurface Structure with Equivalent Offset Migration for multicomponent seismic data
Keywords:Equivalent Offset Migration, Seismic Exploration
In the conventional EOM, it is mainly to use the vertical component of received waveforms, not horizontal components. However, it is necessary to obtain S-wave velocity structure in order to establish the sub-surface model including petrophysical properties. We would like not to employ EOM to take the advantages of the processing efficiency but to extend it to use the horizontal components of waveforms for petrophysical analysis. 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.
