This approach ignores compositional effects on interfacial tension and the impact of pore-size distribution (PSD) with variable phase saturations on capillary pressure and phase behavior. In this paper, we...

... not to strongly affect the relative permeability, although the end point relative permeability to CO 2 decreased with temperature increase from 31.05°C to 38°C. This paper also describes the effects of pressure and temperature on the interfacial tension (IFT) between CO 2 and brine. The IFT was observed...

... emulsions can be formed. The viscosity difference between oil and water, and the reduction of interfacial tensions play important roles in in-situ formation of emulsions. The following is a discussion of the role of possible factors responsible for affecting oil-water interfaces in oil reservoirs. 1...

... was attributable to the polymer buffer used for mobility control. Polymer injection alone recovered 14.1% of the tertiary oil. Crude oil – aqueous phase interfacial tensions were reduced 58 to 92 percent with the MERCO fluids. This is not enough to significantly alter recovery. The MERCO type fluids were also...
