Parameter Study of Polymer-Flooding-Oil-Recovery Method With the Use of CMG

Injecting polymer into the reservoir is a commonly used method to enhance oil recovery in the oilfield. It is usually used when there is a large amount of residual oil in the reservoir after first or secondary oil recovery process. Different reservoir properties like permeability and reservoir heterogeneity can affect the polymer flooding process. This research is mainly focused on how parameters of reservoir will affect the polymer flooding efficiency. The CMG program is used to simulate reservoir and polymer flooding in the reservoir and then help to generate results. CMG is a commercial software package designed for reservoir simulation, and it applies the principles of finite difference method
