... that viscosity (or mobility) ratio primarily controls oil recovery response, and that the recovery is lower at higher viscosity ratios. Further, viscous fingers dominate high viscosity ratio floods, and mobile water can significantly reduce recovery. Field-scale simulation results indicate that heterogeneity...

... in heterogeneous flow systems where crossflow occurs. In any real miscible floods the flow will be anything other than one-dimensional, as reservoir heterogeneity and viscous instability produce faster flow in some zones than in others. Therefore better understanding of the scaling of those interactions...

... for the field-scale simulation. This step takes into account heterogeneity of the facies as well as gravity effects, and is based on steady-state upscaling technique. The upscaled flow functions resulting from the second step depend both on the flow direction and on the flow rate (or pressure gradient...

Mechanisms to leave current remaining oil patterns were investigated in light of areal and vertical characteristics, indicating potentials of improved waterflooding of the remained oil in the reservoirs. delta front sheet sand channel sand structural geology reservoir heterogeneity upstream oil...

... sensitivity analysis. In addition, the effects of rock heterogeneities on the oil recovery and asphaltene precipitation were investigated. A good match with the oil recovery was obtained. Results indicate that higher the degree of heterogeneities, the higher is the asphaltene accumulation in the core...

... Abstract In heterogeneous reservoir containing 2 liquid phases, e.g., oil and water, the flow rate in combination with small to medium scale heterogeneities in both absolute permeability and capillarity defines dynamic capillary entrapment of oil and water. Since those effects involving both...

In regard to the effective longitudinal dispersion coefficient, it is believed that the contribution due to dispersive mixing in small scale heterogeneities will usually dominate any influences due to molecular diffusion. We illustrate this by studying rectilinear displacement in finely gridded...

In the late developing period of such high water-bearing layers, in order to study results of polymer flooding, polymer flooding field test has been conducted in the central part of Xing-Five area of south of oil field...
