Dynamic Cluster Analysis for Updating Simulation Model Using Time-lapse Seismic

4D Seismic data analysis is well established for reservoir characterization and improving reservoir development. Usually 4D seismic interpretation results are used in history matching, but here there are still some arguable considerations regarding its interpretation as well as direct use in such a procedure. The method proposed here avoids ambiguity in seismic interpretation, and thus facilitates the history match. It is especially effective for baffles and barrier location (i.e. reservoir connectivity), and also the identification of fluid pathways in the reservoir.
