Acesso em:.http://bdm.ufpa.br/jspui/handle/prefix/1891The simulation of a zero-offset (ZO) seismic section from multi-coverage seismic data is a standard imaging method widely used in seismic processing to reduce the amount of data and increases the signal-to-noise ratio. In the last years, have appeared diverse stacking methods as an extension of the conventional imaging method, the Commonmidpoint (CMP) stacking, to simulate ZO sections. Examples of such methods are the well-known Common-Reflection-Surface (CRS) stack, Multifocusing stack and Non-Hyperbolic CRS stack. The accuracy of these methods differs and depends not only on distance but also the reflector curvature and do not consider the seismic anisotropy. Recently an implicit traveltime approximation for monotypic waves in anisotropic media was proposed to simulate ZO sections, called implicit Common-Reflection- Surface (i-CRS). This new approximation depends on the same three parameters as the conventional CRS method. In this work, we tested the performance of this approximation to simulate ZO seismic sections by considering primary and symmetric multiple reflections.Acesso AbertoMétodo de reflexão sísmica - Processamento de dadosProspecção SísmicaCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOFISICA::SISMOLOGIATrabalho de Curso - Graduação - Monografia
