Abstract

Flexi binning technique can some time be used to get the most out of irregularly acquired 3D land surveys, but cannot be ignored in marine 3D seismic data processing. This paper clearly shows how this technique can help in filling the gaps or holes in subsurface coverage providing a constant fold and uniform distribution of the offsets within each bin of 3D seismic volume. Though there are interpolation techniques which can fill the holes in coverage by reconstructing the missing traces, but the complexity of the structure effects the quality of the output from these interpolation algorithms. Further in prestack mode the flexi gathers can handle the multiples, noise and velocity analysis with greater confidence.
