The effect of cationic surfactants on polymer viscosity at different temperatures was investigated. The compatibility of the mixtures of the cationic surfactants and the anionic polymers...

... performance is demonstrated. Viscosities of polymer solutions prepared with surfactant S1 are slightly higher (than viscosities with surfactant S2) and decrease with increasing surfactant concentration at constant polymer content. Besides, RRF values as a measure for injectivity behavior strongly decrease...
