Method for transportation of viscous hydrocarbons by pipeline

Patent ·
OSTI ID:5850154
A method of transporting viscous hydrocarbons is described, which involves introducing into a pipeline or well-bore with the viscous hydrocarbons a solution containing an oxyalkylated anionic surfactant such as sodium nonyl phenol polyoxyethylene sulfonate or a mixture of such surfactants and, optionally, with an alkalinity agent thereby forming a low-viscosity, salt-tolerant oil-in-water emulsion.
