Abstract Wormlike micelles, obtained in anionic surfactant sodium oleate (NaOA) solutions in the presence of sodium phosphate (Na 3 PO 4), were studied using the steady and dynamic rheological methods.The laboratory simulation flooding experiments were used to investigate the effects of flooding for the wormlike micelles system.The results show that the oil recovery is 32.7%.This flooding system is a new type and has high activity with a low cost.
