... with relatively high partition coefficients were shown to be better foam and emulsion breakers compared to agents with low partition coefficients. The effectiveness of a partitioning agent in breaking foam and emulsions can vary depending on both temperature and salinity. Partitioning agents such as aryl-based...

... for different heterogeneities, tracer reaction rate, partition coefficients and tracer soak time. Analysis of the synthetic SWCTT result shows that our analytical approach correctly estimates oil saturation. The calculated residual oil from our analytical model was consistently within ±0.02 saturation units...

..., ABS, L, and S type hydrophobes is variable. The B and A type hydrophobes correspond to only the oleyl alcohol and tristyrylphenol hydrophobes, respectively. The partition coefficients, K OW,k and K PW,k , are a measure of the relative affinity of the co-solvent for the oil, water, and surfactant...

...-solvents between phases to better understand their behavior and how to select the best co-solvent for chemical EOR. There is an optimal co-solvent partition coefficient for microemulsion systems. Commercial co-solvents used for chemical EOR are actually mixtures of different components. We used HPLC...

... Taylor-like series ( Zissimos et al. 2002 ). Based on this, sigma moments have been used to predict properties of molecular ensembles such as partition coefficients and adsorption enthalpy using linear equations ( Mehler et al. 2002 ): μ ≅ c 0 + ∑ c i M i where c 0...
