The Chemflood allows for various chemical flooding tests including polymer flooding, Alkaline-Surfactant flooding and foam injection. Those tertiary methods improve oil recovery. Polymers increase the viscosity of injected fluid and decrease the oil/water mobility ratio. Surfactant and alkali reduce the interfacial tension between oil and the injected aqueous formulation. Foam improves the sweep efficiency of surfactant injected into fractured reservoirs. The Chemflood device is ideal to understand the effects of chemical injection compatibility and assess the various chemicals to be injected at reservoir conditions. Change in permeability, displacement efficiency and incremental oil recovery due to polymer injection can be studied with this setup. Typical configuration of a chemflood system includes injection pump, four fluid transfer vessels, pressure tapped coreholder, forward and backward injection facilities, confining pump, back pressure regulator, airbath, pressure measurement system, PHmeter, fraction collector and data acquisition system.
