CFD Simulation of the Oil Displacement in Micromodel for Enhanced Oil Recovery Application

Abstract Diminishing hydrocarbon reserves in oil reservoirs and the need to sustain continuous production have prompted researchers further investigate Enhanced Oil Recovery (EOR) techniques. Researchers also test run these processes before EOR fluid injection into reservoir maximise whilst minimising damage loss. This study aims simulate displacement during of two different types fluid, namely water polymer, using a commercial CFD software known as ANSYS Fluent. A heterogeneous 2D micromodel that has randomised pore network was selected basis flow system. By doing so, it is hoped replicate prototype an innovative approach geometry appropriately simplifies complex properties represented. Initially, fully saturated with crude oil. Then, polymer are injected separately on case-to-case at flowrate 0.8 mL/min. Visual inspection phase fraction contour results found flooded had smaller regions volume compared micromodel. Polymer more branched fingering front The analysis flooding better efficiency traditional due higher mobility ratio, reduced viscous lower residual saturation.
