Permeability updating of the simulation model by use of 4D-seismic data

A method is presented for updating a reservoir-simulation model by incorporating permeability that is derived directly from time-lapse-seismic data. The proposed method builds new permeability distributions by integrating a previous 3D-simulation model with 2D-permeability maps from the timelapse-seismic results. These updates provide an alternative to use of a conventional gradient-based historymatching tool by itself. The largely uncertain petroelastic model can be avoided when history matching to the time-lapse-seismic data. Copyright 2009, International Petroleum Technology Conference.
