“…The post-salt reservoir is characterized by clean, high-porosity turbiditic sandstones (from the Maastrichtian age), saturated by heavy oil (17 • API). The average water column is 1355 m, and the average depth of the reservoir is 2800 m. More details on the geological setting of the Jubarte field and the acquisition and processing of the permanent reservoir monitoring (PRM) seismic data can be found in Ramos Filho et al (2017), Thedy et al (2015) and Dariva et al (2016). The focus of these publications is on the description of the seismic data and on the qualitative interpretation of the 4D anomalies observed between the Jubarte PRM seismic vintages.…”

The added value of the joint pre‐stack inversion of PP (incident P‐wave and reflected P‐wave) and PS (incident P‐wave and reflected S‐wave) seismic data for the time‐lapse application is shown. We focus on the application of this technique to the time‐lapse (four‐dimensional) multicomponent Jubarte field permanent reservoir monitoring seismic data. The joint inversion results are less sensitive to noise in the input data and show a better match with the rock physics models calibrated for the field. Further, joint inversion improves S‐impedance estimates and provides a more robust quantitative interpretation, allowing enhanced differentiation between pore pressure and fluid saturation changes, which will be extremely useful for reservoir management. Small changes in reservoir properties are expected in the short time between the time‐lapse seismic acquisitions used in the Jubarte project (only 1 year apart). The attempt to recover subtle fourth‐dimensional effects via elastic inversion is recurrent in reservoir characterization projects, either due to the small sensitivity of the reservoirs to fluid and pressure changes or the short interval between the acquisitions. Therefore, looking for methodologies that minimize the uncertainty of fourth‐dimensional inversion outputs is of fundamental importance. Here, we also show the differences between PP only and joint PP–PS inversion workflows and parameterizations that can be applied in other projects. We show the impact of using multicomponent data as input for elastic seismic inversions in the analysis of the time‐lapse differences of the elastic properties. The larger investment in the acquisition and processing of multicomponent seismic data is shown to be justified by the improved results from the fourth‐dimensional joint inversion.

“…The Jubarte experiment (JE) [41][42][43] was the first attempt to develop an understanding and assess the sensitivity of the CSEM method to water flooding associated with oil production in a complex and heterogeneous deep-water Brazilian turbiditic reservoir. The Jubarte Reservoir was chosen because it hosted the first fully optical deep-water permanent reservoir monitoring (PRM) seismic system installed in Brazil [44].…”

The controlled source electromagnetic (CSEM) method is frequently used as a risk reduction tool in hydrocarbon exploration. This paper aims to provide a comprehensive historical review of the CSEM method’s twenty-year history in the Brazilian continental margin. Since 2003, we have significantly improved our understanding of CSEM resistivity data across various geological scenarios. This review presents a roadmap of the technical advancements in acquisition design and interpretation techniques. As a result, our understanding of the methodology has broadened from traditional to more general use, such as salt imaging, gas hydrates, geohazard mapping, and reservoir characterization. Finally, we indicate the potential upcoming CSEM applications in new energy resources and carbon capture and storage.
