Resumo:
The seismic stacking has as objective to obtain a final product of seismic imagem more realistic in the subsurface. In the last years, has been used several seismic stacking methods in order to overcome constraints of stacking commom midpoint gathers (CMP). Among these methods, stands out the Stacking Common-Reflection-Surface (CRS), in which the traveltime aproximattion is hyperbolic. Recentlly, it has been pruposed the non-hyperbolic traveltime approximation to simulate ZO sections . This work, we tested the performance of the non-hyperbolic CRS approximation to simulate primary reflections and symmetrical multiple events. The results shown to be an important alternative in seismic stacking, obtaining a good performance in simulating seismic sections with ZO with reflections primary and symmetrical multiple events.
