Through the past early years, reservoir simulation has evolved from a research area into one of the most practical and powerful tools in reservoir engineering. Usage of reservoir simulation has been grown very fast because of its ability to predict the future performance of oil and gas reservoirs over a wide range of operating conditions. Reservoir simulation is normally used as an important reservoir management tool and play a very important role for production optimization from oil and gas resources. History matching is the most challenging and critical task during the reservoir simulation study, in order to have a reliable prediction of reservoir behavior in future
