With a continuous increase in the worldwide demand for the crude oil and considering the fact that conventional oil and gas resources are depleting, the Enhanced Oil Recovery processes (EOR) play a vital role to boost the production from mature reservoirs. Chemical Enhanced Oil Recovery (cEOR) is one of the most implemented methods to produce the remaining oil in-situ. Alkali-Polymer flooding is a cEOR technique in which the alkali should react chemically with the oil to produce in-situ surfactants/soaps. Polymers solutions are expected to provide fluid mobility control and improve the sweep efficiency. Hence, it is crucial that the viscosityof a polymer solution does not decrease throughout its propagation along the reservoir.
