Permanent Reservoir Monitoring at Jubarte Field - 4D Results and Reservoir Characterization

At the end of 2012, Petrobras installed the first deep-water optical permanent reservoir monitoring (PRM) system over the Jubarte oilfield in the Campos basin offshore Brazil. The PRM pilot project covered approximately 9 sq. km with a fully fiberoptic 4-component (4C) sensor array. All topside optoeletronic equipment was installed on FPSO P-57. The primary objective was to validate the fiberoptic sensing technology to detect subtle impedance changes in the reservoir. This goal was achieved, allowing interpreters to apply an interpretation strategy to improve the understanding of flow patterns and to update the geological scenarios of the area based on very high quality 3D/4D images provided by the permanent system.
