In addition to the reliability of static and dynamic data integration，the proposed method can reduce the number of dynamic simulations drastically compared to the ensemblebased methods（Table 8）.The ES requires simulated WOPR for each initial model to compare with the true WOPR during history matching.After that，dynamic simulation for each updated model is needed to predict future productions.Therefore，the number of forward simulations from the ES is 400 in total.The EnKF demands many more forward simulations for history matching because it assimilates model parameters every dynamic data acquisition time.In this case，the EnKF requires 9000 ECLIPSE runs for history matching，which is the product of totalmodels（200）and the number of dynamic data acquisitions（45）.
