... flow simulation. The key contribution here is the addition of compressibility, which additionally makes possible the study of the effect of external boundaries. Absent compressibility, the necessary condition for the growth of a viscous finger is simply the mobility ratio, M>1. It is the objective...

... and optimization. Heavy oil waterfloods introduce challenges to the application of CRM due to the high mobility ratio and its rapid variation as a function of waterflood maturity. Using conceptual reservoir models and sensitivity studies, we provide guidelines for application of CRM in heavy oil waterfloods. We...

Crump (1988) applied modified T-L model using mobility ratio dependent mixing model along with Koval heterogeneity factor H k determined from...

... is by the synergistic effect of polymer to improve mobility (slow down the movement of water to match that of the oil, i.e., mobility ratio of 1) and surfactant (with or without alkaline) to reduce the interfacial tension between oil and water to displace the discontinuous trapped oil remained in reservoir after...

... effluent salinity profiles across floods, qualitative understanding of dispersion and macroscopic stability is developed. Plots show a reduction in dispersion for LTG flooding versus surfactant flooding, which indicates improvement in mobility ratios across the displacement fronts. Macroscopic stability...

The new index is able to rank reservoirs, both accurately and quickly, based on performance for both miscible and immiscible fluids at a range of different mobility ratios. In contrast both the Dykstra-Parsons coefficient and the dynamic Lorenz coefficient...

... of which is associated with an adverse mobility ratio. The adverse mobility ratio across this shock is not very large, about 1.5 to 3.75 in the cases considered. As the viscosity ratio increases, the width of the oil bank decreases and one of the shocks disappears at high viscosity ratio (>10...
