The reduction of interfacial tension between acidic oils and floodwater is one of the most important mechanisms of enhanced oil recovery. An experimental study was conducted to elucidate the mechanisms of the interfacial tension behavior arising from the interaction between an acidified oil and a pure surfactant. A model oil system was used to examine the influence of acid and surfactant concentrations on interfacial tension. With sodium dodecyl sulfate as the added surfactant, the interfacial tension was lower than with either surfactant alone or acid alone and no minimum in interfacial tension was observed.
