Improved Multiple Attenuation through 5D Near-Offset Extrapolation for Convolutional 3D SRME and Optimized Adaptive Subtraction

THE authors present a workflow that uses a 5D interpolation scheme to reconstruct near-offsets beyond what is originally recorded in the legacy azimuth to improve multiple modelling. Combined with an optimized adaptive subtraction flow that separates multiples into fast and slow components, the final data show significant improvements in multiple attenuation compared to legacy data sets in the area.
