The Investigation of the Anionic and Cationic Surfactants effects on the enhanced oil recovery in Iran oil reservoir
Author(s): Elyas Golabi
Abstract: The oil recovery by water flooding from the carbonate reservoir is not effective because of the capillary forces in naturally fractured oil-wet carbonate formations. Alkaline/surfactant solution is recommended to enhance the spontaneous imbibition between the fractures and matrix by both wettability alteration and ultra-low interfacial tensions.
In this study the effects of anionic surfactant, from sulfate family, and a cationic surfactant, from CnTAB family, on the interfacial tension (IFT), wettability alteration and spontaneous imbibition of oil and outcrop rock samples obtained from Aghajari reservoir were investigated. The experimental results show the effectiveness of these surfactants to be used in this Enhanced Oil Recovery scenario at very dilute concentrations.
