This paper presents measurements of interfacial tension (IFT) and tertiary oil recovery (TOR) of triglyceride microemulsion flooding over a wide range of aqueous phase compositions. Based on 160experimental data sets, two empirical correlations were established. Both the power-law and logarithmic models were validated statistically. Power-law and logarithmic models are predicted to perform best at ultralow IFT range (<0.001 mN/m) and high IFT range (>2 mN/m), respectively. The valid models indicate that IFT is the sole parameter affecting the cumulative TOR in a triglyceride microemulsion flooding. This phenomenon, however, does not apply in hydrocarbon-based microemulsions.

This paper presents the application of response surface methodology to predict the optimum aqueous phase composition of a triglyceride microemulsion for enhanced oil recovery. The two models capturing the relationships between interfacial tension and tertiary oil recovery data with the aqueous phase composition were validated prior to optimization. It was predicted that the optimum aqueous phase contains 3 wt% sodium chloride, 0.98 wt% alkyl polyglycosides, and 2.98 wt% glyceryl monooleate. At this composition the corresponding interfacial tension is minimum (0.000229451 mN/m) and the tertiary oil recovery is maximum (71.7865%). The predicted optimum aqueous phase composition using historical-data design is close to the experimental value.
