Abstract

The interfacial tension that exists amid crude oil and brine can be lowered by chemical surfactant flooding as a result of the mobilization of trapped oil. The influence of surfactants on the interfacial tension (IFT) that exists in a heavy crude oil/ brine system was examined experimentally. The influence of surfactant concentration was observed. The laboratory experiments were performed at ambient and reservoir temperatures. Five different surfactants were made use of; two industrial surfactants (Alpha Olefin Sulfonate and Methyl Ester Sulfonate) and three formulated surfactants from vegetable oils (surfactants from Jatropha, Castor, and Palm kernel oils). The heavy crude oil was acquired from a field X in the Niger Delta, and the brine used was prepared in the laboratory. IFT between brine and heavy crude oil was measured by means of the Du NOUY ring. From the results, it was found that the Castor oil derived surfactant performs best at both ambient and reservoir temperatures.
