Using CSEM to Monitor the Production of a Complex 3D Gas Reservoir – A Synthetic Case Study

The marine CSEM method is currently being applied to the problem of detecting and characterizing hydrocarbons in a variety of settings for exploration purposes. Because of its physics it can on one hand, distinguish between fluids within formations. On the other hand, it can suffer from a poor resolution in positioning those bodies in the vertical plane. The purpose of this presentation is to highlight the possibilities and challenges the CSEM technique will have to face to successfully play a key role during monitoring phase of a hydrocarbon reservoir life cycle. This will be illustrated using synthetic data from a complex meandriform anticline channel charged with gas.
