Acesso em:.http://bdm.ufpa.br/jspui/handle/prefix/1219The processing of seismic data acquired in the 80´s has as main problem the reduced fold coverage and a low signal-to-noise ratio. This kind of difficult directly interferes in the final quality of the seismic sections, impacting in the evaluation of the exploration potential of some sedimentary basins. Dozens of seismic lines acquired over the Tacutu Basin belong to this context of failure of the exploratory process, in which the seismic processing techniques applied at the time were unable to provide high-quality seismic images to characterize non-conventional oil accumulations, for example, in fractured basalt. This work compares the results of the conventional CMP stacking technique and the non-conventional CRS stacking technique applied on the lines 204-RL-239 and 204-RL-247, acquired over the Tacutu Basin. The main objective is to show the effectiveness of the CRS stacking technique in generating seismic images displaying a more representative local geology using low coverage data. The significant gain in quality of the final sections processed using the CRS method was sufficient to complete this work successfully.Acesso AbertoProcessamento sísmicoEmpilhamento CRSRio Tacutu - RRCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOFISICATrabalho de Curso - Graduação - Monografia
