Crs-Prestm: Migração Pré-Empilhamento Em Tempo Usando O Operador Crs

The common-reflection-surface (CRS) stacking method produces stacked zero-offset (ZO) sections with a high signal-to-noise ratio, a good definition of the lateral continuity of seismic reflections as well as of reflections with steep dips. The stacking operator of the CRS method depends on three kinematic attributes that are determined through optimization algorithms from the prestack data. In spite of the good results obtained so far with this method, there are still problems to be bypassed, such as the correct simulation of events with conflicting dips and diffraction events. In this work we present one application of the CRS stacking operator in the prestack time migration, i.e., instead of simulating a ZO stacked section, the result is a time migrated section. To demonstrate the efficiency and robustness, we apply this new prestack time migration approach based on CRS method in a synthetic and real land dataset.
