It was applied a seismic processing flow for high-resolution 2D marine data, related to a survey realized with the Chirp Sub-Bottom Profiler in the Campos Basin. The processing this data is fundamental to improve their low signal-to-noise ratio, characterized primarily by the presence of multiple reflections of seafloor and strong seismic signal attenuation, which becomes difficult the identification of geological information in the section. The application of processing flow was based according to the characteristics of shallow seismic data presents such as: the type of acquisition (single-channel), the behavior of the high-frequency signal, type of gain and filter type, being composed of basic steps necessary for a general flow and some supplementary processes, in which stand out the application of Predictive Deconvolution that allowed to obtain satisfactory results in multiple attenuation of seafloor.
