Surface-related multiple removal with inverse scattering series method

Multiple removal is a key process in seismic data processing, the effect of multiple elimination directly affects the final imaging. In this paper, inverse scattering series method is based on wave equation and Born series, multiples are predicted and removed by constructing a subseries corresponding to surface-related multiples. This method does not need any subsurface information and is suitable for different kinds of complex structures. However, source wavelet and near offset traces information will be needed for applying this technique. Energy minimizing method and band-limited parabolic Radon transform is employed to meet the above two conditions. The examples of a synthetic data study and a marine data show that the free-surface multiple can be well attenuated in both prestack gathers and seismic section by implementation with inverse scattering series method.
