Paper presented at the Annual Technical Meeting, June 13–17, 1999
Paper Number: PETSOC-99-35
... Abstract Viscous fingering takes place when the viscous forces of a displacing phase has greater momentum than that of the displaced phase. Viscous fingering is an extremely important phenomenon in many applications of enhanced oil recovery, underground liquid waste disposal, and geothermal...

Since emulsion flooding is a complex EOR process involving several mechanisms that occur at the same time during displacement, simulation of oil recovery by emulsion flooding requires an understanding of the flow mechanics of emulsions in porous media. With this end in view, the present study...

... Abstract Enhanced oil recovery operations often involve immiscible displacement of the more viscous oil by a less viscous fluid. This often leads to an unstable and inefficient displacement process because of fingering of the more mobile displacing fluid through the more viscous oil. Although...
