4D Seismic Modeling Integrated with the EnKF Method for History Matching of Reservoir Simulation Models

From a real Norwegian North Sea field case we show results from 4D seismic modeling using Eclipse simulated reservoir parameters in an Ensemble Kalman Filter framework, short EnKF. Seismic and geologic modeling is performed via the Compound model builder, our interface shared by geophysical and reservoir engineering data. The EnKF method is a Monte Carlo type sequential Bayesian inversion method suitable for history matching of reservoir simulation models and recently extended to incorporate seismic data.
