Automating prestack migration analysis using common focal point gathers

CFP technology (Berkhout, 1996a,b) addresses these limitations in a novel way. By breaking the model determination process into two simpler, more easily solved problems, those of operator estimation and macro model estimation, the final solution will typically be more accurate. Moreover, by providing rapid local convergence to the correct travel-time operators, migration analysis can be automated, resulting in reduced manpower requirements and shorter time-to-solution.
