ABSTRACT:
A method for transporting viscous hydrocarbons which involves introducing into a pipeline or well-bore with the viscous hydrocarbons a solution containing (1) an anionic surfactant such as sodium tridecyl sulfate, sodium oleate, etc., or an oxyalkylated anionic surfactant of the sulfonate or sulfate type, and mixtures of the surfactants mentioned and (2) an alkalinity agent such as sodium hydroxide, thereby forming a low viscosity, salt-tolerant, oil-in-water emulsion. Optionally, the solution may contain a small amount of a guanidine salt or a water-soluble oxyalkylated, nitrogen-containing aromatic compound such as ethoxylated-8-hydroxy quinoline.
