Diffraction Imaging Based on Sliding Grouping the Dip-Angle Gathers From Inverse Scattering Prestack Depth Migration (opens in new tab)

We developed a novel diffraction imaging method based on dip-angle gather processing within the inverse scattering migration framework. The method generates a dip-angle domain common imaging point gather based on the inverse scattering prestack depth migration, utilizes the energy distribution difference between reflection and diffraction in the dip-angle gather, constructs an imaging waveform sequence of dip-angle traces, and slides and groups the gather along the dip-angle direction to dete...
