This acquisition strategy enables not only to optimize the illumination of complex structures, but the reservoir characterization with analysis of seismic attributes variations as a function of offset, and azimuth. However the processing of those surveys requires the application of specific workflow, different from the conventional one used for data with narrows azimuths. In 2009, Petrobras acquired a new orthogonal, wide azimuth 3D survey covering Araçás, Fazenda Boa Esperança and Mandacaru onshore fields (Figure 1), where a previous slant 3D was already available. Despite the good result obtained by new acquisition, it needed to be submitted to an appropriate workflow for wide azimuth data, known as COV - Common Offset Vector, to evaluate if such a technique could further improve the results already obtained by the new 3D. With that purpose Petrobras contracted third services to reprocess the new 3D using the COV technique. The obtained improvements confirmed the effectiveness and importance of COV workflow for wide azimuth data. The company is now preparing to internally develop the codes and expertize to extend the wide azimuth processing technology to other areas.
