“…However, the lack of data in the crossline direction makes 3D ISS prediction difficult for conventional streamer data. We overcome this difficulty by constructing high-density and wide-azimuth data from the existing streamer geometry, the same approach that was used in 3D SRME (Lin et al, 2004) and 3D internal multiple attenuation (Hung et al, 2013). In this paper, we discuss the implementation of 3D ISS internal multiple attenuation and apply the method on synthetic and real seismic datasets.…”
