We present Alkyl polyglycoside (APG)/1-naphthol formulations which show ultra-low interfacial tensions (IFT) against n-octane. We demonstrate that 1-naphthol is very efficient as a cosolvent in terms of reducing IFT. These formulations are therefore potentially suitable as agents for enhanced oil recovery (EOR). an increasing APG concentration strongly increased viscosity, and the formulations showed shear-thinning behavior. in a core flood EOR test we showed that this type of formulation significantly increased oil production. © 2010, European Association of Geoscientists and Engineers.
