Finger Thickening during Extra-Heavy Oil Waterflooding: Simulation and Interpretation Using Pore-Scale Modelling
Fig 5
Comparison between (a) simulations and (b) experiments of Mercury (Black) displacing air (white) (viscosity ratio M = 0.0111). NCa is the Capillary Number and measures the ratio of viscous to capillary forces (see Eq (22)). Fig 5 is composed of images from Fig 10c in Lenormand et al [18].
