DefinitionSurfactant flooding is guessing of one or more liquid chemicals and bedwetters. The phase behaviour properties in the oil reservoir is effectively controlled by the surfactant, which then help to marshal the trapped crude oil by reducing interfacial tensity (IFT) between the injected liquid and the oil. So for the oil to move through the shockable capillary focalises a very low oil or irrigate IFT is needed. Surfactant flooding also increases the economic productivity. In order to break the properties of the surfactant solution, co-surfactants are being mixed up into the liquid surfactant solution. This co-surfactant actually acts as a promoter or as an active agent agent in the mixed surfactant solution. This is to provide optimal conditions with revere to temperature, pressure and salinity. Reservoir has a certain physical characteristic, thus delinquent to this characteristics e.g. adsorption the binding of molecules to the rock and trapping of the fluid in th e pore structure, considerable losses of the surfactant may occur. The stability of the surfactant constitution at reservoir cond...
