Acesso em:.https://repositorio.ufpa.br/handle/2011/11599Seismic Imagining is one of the manners to visualize on subsurface. To get at a reliable seismic imagining, a long way must be covered. The first stage is the seismic acquisition, its the planned evil its carries serious troubles. After the seismic acquisition we need to processes the data. Seismic data processing is alteration of seismic data to suppress noise, enhance signal and migrate seismic events to the appropriate location in space. Processing steps typically include analysis of velocities and frequencies, static corrections, deconvolution, normal moveout, dip moveout, stacking, and migration, which can be performed before or after stacking. In this work, our objective is a seismic migration from a Camamu basin 2D acquisition line. In this line we have many the dificulties arise from the factors free surface multiples e peg-lags. We are going to use as seismic processing methodology the common median point stack and the pos-stack migration by ProMax (Landmark Inc) software. To attenuate multiples we have used predictive deconvolution, radon filter and f - k filter techniques . The results are satisfactory when we compare to results without theses techniques.Acesso AbertoProspecção - Métodos geofísicos - BahiaProcessamento sísmico convencionalAtenuacão de múltiplasMigração pós-empilhamentoConventional seismic processingMutiple atenuationPos-stack migrationDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOFISICA::SISMOLOGIAMÉTODOS SÍSMICOS
