... variation, viscosity reduction, asphaltene and resin precipitation. These variations during TEOR impact relative permeability to each fluid phase in the reservoirs. Therefore, available models like the Corey model and Stone's model for estimating the relative permeability cannot be directly used...

Thus, the heat-scavenging effects of water buildup around the injection well and low relative permeabilities of oil traveling through the high water saturation interval are avoided. The estimated SOR during the CSS process depends on the oil viscosities...

... into small water-wet pores. Thus the larger pores regain a higher oil saturation as well as higher oil relative permeability which contribute to a better early production. However, this model might not be valid because if small pores are filled with oil, the wettability of small pores are more prone...

... composition on the relative permeability is commonly neglected in both experiments and models and may lead to erroneous predictions of reservoir performance. Therefore, we have developed a general framework to calculate aqueous-composition- dependent relative permeability. The expected relative permeability...

... The Stone I model suggests that, in a water-wet medium, relative permeabilities of gas and water (non-wetting and wetting phases) are the same as their two-phase counterparts as observed in gas-oil and oil-water displacements, respectively.
