History matching of experimental and CMG‑STARS results
Abstract
At present, chemical fooding is one of essential enhanced oil recovery methods. In this study, three core fooding experiments (brine fooding, Alkaline, and Alkaline + Ionic Liquid slug fooding) were selected for history matching using CMG-STARS. Depending on the composition of the chemical slug, two pore volumes were injected into the porous medium to enhance the RF of heavy oil (14° API). We observed that the most challenging part of building up the model was relative permeability curves. So, the relative permeability values were tuned to end up with a successful match of cumulatively produced oil and water cut. Finally, history matching is signifcant to apply a wide range of assumptions and upscale the experimental results.
