GOMES, Moab Praxedes; VITAL, Helenice  and  MACEDO, José Wilson de Paiva. Fluxo de processamento aplicado a dados de sísmica de alta resolução em ambiente de Plataforma Continental: exemplo: Macau-RN. Rev. Bras. Geof. [online]. 2011, vol.29, n.1, pp.173-186. ISSN 0102-261X.

This paper presents a proposal for a processing flow applied to high-resolution seismic data. It is organized in the implementation steps of operations and takes in account different factors in the flow organization. Usually used as raw data, the high resolution seismic processing is little discussed in literature. It differentiates in many aspects of processing used in conventional seismic data. The application of the processing flow to shallow seismic data was based on key criteria such as: behavior of a wave of high frequency, properties of the environmental, operation of the filters, gain, which allowed to obtaining a result with a better quality than the raw data. The flow defaults a logical sequence of procedures (header edition, filter, gain, deconvolution) for this kind of data, with basic steps, necessary for a general flow, and some additional processes, revealing potential problems and their solutions.

Keywords : shallow seismic; seismic processing; continuous acoustic profiling.
