Abstract

Summary

In this study, the effective mechanisms of fluid flow for improve oil recovery using alkaline and cationic surfactant flooding process had been investigated in a five-spot glass-micromodel system. The Alkaline-Surfactant (A.S) solutions were used in different concentrations where they constituted of C19TAB as a cationic surfactant and NaOH as an alkaline. Alkaline reacts chemically with acidic components of crude oil and generates Sodium naphthenate (soap) in situ. Therefore, soap is a kind of anionic surfactant. Also we measured recovery factor for different concentrations of surfactant and A.S solutions using two methods of flooding as the secondary and the tertiary chemical flooding methods and then we compared the sweep efficiency of surfactant and A.S solutions together in the both methods of chemical flooding.
