Optimal Salinity of Polymer Solution in Surfactant-Polymer Flooding Process

A systematic study of the effects of the salinity of connate water and polymer solution on oil-displacement by aqueous and oleic surfactant formulations was carried out. For both types of surfactant formulations, the maximum oil recovery was observed when the salinity of the polymer solution was at the optimal salinity of the preceding surfactant formulation. It is shown that the processes occurring at the surfactant slug-polymer solution mixing zone dominate the oil recovery efficiency. Polymer solution having the optimal salinity of the preceding surfactant formulation assures that the interfacial tension of oil ganglia or middle phase micro-emulsions with polymer solution will remain low. The low inter-facial tension together with adequate mobility control displaces the surfactant slug in a piston-like manner.
