Pore-scale viscous fingering in porous media
WebRESUMO. Viscous fingering in porous media during CO 2 flooding is investigated experimentally as well as numerically in this study. Experiments were accomplished in real cores saturated with simulated oil in thermostat, and the effect of CO 2 flooding is studied in homogeneous cores with differing permeability and viscosity under various pressures. . … WebAug 18, 2011 · @article{osti_1024083, title = {Influence of Viscous and Capillary Forces on Immiscible Fluid Displacement: Pore-Scale Experimental Study in a Water-Wet Micromodel Demonstrating Viscous and Capillary Fingering}, author = {Zhang, Changyong and Oostrom, Martinus and Wietsma, Thomas W and Grate, Jay W and Warner, Marvin G}, abstractNote …
