The Employment Of CMG-STARS To Simulate Alkaline/Ionic Liquid/Polymer (AILP) Flooding Results
Abstract: One of the most successful enhanced oil recovery techniques, nowadays, is chemical (Alkaline/Surfactant/Polymer) flooding and modeling the experimental results of these experiments is one of the most difficult challenges. For that, this study has been conducted to obtain the history matching of the laboratory scale results employing STARS. Some of the chemical flooding experiments have been done to get additional RF. We noticed that the most challenging factors throughout building up the models were the pure polymer viscosity and oil-water relative permeability curves. Also, a fair range of assumptions was made to address the unavailability of any information and adjust the particular values to end up with a successful match of cumulatively produced oil, water cut, oil cut, and pressure drop curves. Finally, understanding how to model the chemical flooding performance in laboratory scale will develop the possibility of simulating chemical floods in industrial scale.
