Assessing Weighting Coefficients in Seismic History Matching of the Norne Field
4D seismic data has become an important tool for oil and gas field operators. Reservoir characterization, evaluation and monitoring are all improved by including seismic data in the history matching routine.History matching is a process for improving the model by changing its parameters until it rep...
