Popis:	SummaryThis paper investigates pore-scale mechanisms of both wetting and nonwetting phase dropout and flow at low interfacial tensions (IFT's) (approximately 0.1 to < 0.01 mN/m) by use of transparent 2D micromodels with a partially miscible binary fluid system. Quantification is possible with this liquid system because it has uniquely defined physical properties at any given temperature. Phase dropout and flow behavior at phase saturations of < 10% are emphasized. Wettability effects are dominant, but the fluid/fluid interactions change as the IFT drops. The ramifications for the relative permeability curves are discussed.
