Time-Lapse CSEM Monitoring: Correlating the Anomalous Transverse Resistance with SoPhiH Maps

The CSEM method, which is frequently used as a risk-reduction tool in hydrocarbon exploration, finally moving to new frontier: reservoir monitoring and surveillance. In the present work, we time-lapse interpretation workflow. One essential aspect of our workflow demonstration linear relationship between anomalous transverse resistance, an attribute extracted from data inversion, SoPhiH attribute, estimated fluid-flow simulators. Consequently, it possible reliably estimate maps surveys using such relationship. We demonstrate workflow’s effectiveness mature Marlim oilfield by simulating response after 30 40 years seawater injection detecting remaining sweet spots reservoir. reservoirs are analogous several turbidite worldwide, can also be appraised with proposed prediction inversion significantly improve characterization.
