Compositional Modeling of Surfactant Adsorption in Chemical Flooding with Verification with Laboratory Data, M.Sc. Thesis Sharif University of Technology ; Jamshidi, Saeed (Supervisor) ; Ghazanfari, Mohammad Hossein (Supervisor)
Abstract
One of the most important EOR methods in oil reservoirs is surfactant and polymer flooding. Surfactants cause decreasing in interfacial tension between oleic and aqueous phases. However, polymers give us efficient mobility control in displacing oil by increasing the viscosity of aqueous phase. Therefore, oil is displaced in aqueous phase by viscous forces.
One of the most important challenges in surfactant flooding is adsorption. The net surface charge distributed on the rock surface depends strongly on pH. When we inject surfactant in reservoir, electrostatic charge on rock surface causes the first-layer adsorption. After that we have had second-layer adsorption. In this thesis we...
