Abstract

Abstract:

Herein, viscosity reduction is achieved for four different kinds of heavy oil based on the "generalized" cationic/anionic surfactants dodecanoic acid and dodecylamine. Two methods are employed in this work to reduce the oil viscosity of the oil. The first involves emulsifying the common heavy oil with an aqueous solution of "generalized" cationic/anionic surfactants, which can lead to an oil-in-water emulsion. The other requires dispersing the heavy oil in a mineral oil solution of "generalized" cationic/anionic surfactants. 95%-95% reduction is achieved for all heavy oils investigated thus treated.

Key words: "Generalized" cationic/anionic surfactant, Heavy oil, Emulsification, Viscosity reduction
