Abstract: Complex surfactant systems are mixtures of long chain alkyl quaternary salts or long chain alkyl pyridine chloride with sodium salicylate; of anionic surfactants with cationic surfactants and of some zwitterionic surfactants with cosurfactants, anionic and cationic surfactants. The solution of the system takes on high viscosity, notable viscoelastical property and shear thinning behavior. The new type of rheology controller has its application potential in drilling, Enhanced Oil Recovery (EOR) and liquid tr...

Key words: surfactant, rheology controller, application
