Acesso em:.https://repositorio.ufpa.br/handle/2011/11569The seismic record in 2D linear events are common features in the seismograms. These events are overlap with interesting reflections (early reflections) complicating the stages of seismic processing and identification of possible subsurface geological horizons. It possible highlight multiple surface that distinguished from others by a low frequency, high amplitude and low velocity of propagation. The identification and removal of multiple reflflections in seismic data is a real step of great importance in seismic processing, because the attenuation can prevent many of these errors in the interpretation of geological images seismic. This study is the determination of a processing flow for multiple attenuation free surface. Methods of elimination of multiple surface (SRME, Radon filtering, predictive deconvolution domain τ - p and fk filltering) applied to a real data 2D were used in different combinations. These are analyzed and presented the results are the best combinations.Acesso AbertoEliminação de múltiplas de superfícieMétodos de reflexão sísmicaSRMEFiltragem RadonDeconvolução preditiva no domínio tau-pFiltragem f-kProcessamento de dado marinho real 2DSeismic reflection methodAttenuation multiple free surfaceRadon filteringPredictive deconvolution τ - p domainSurvey of mariner real data 2DSurvey of mariner real data 2DDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOFISICAMÉTODOS SÍSMICOS
