Abstract

Abstract: The theological behavior of the ASP (Alkaline-Polymer-Surfactant) system with different formulations was measured by rheomters (HAAKE RV-100 and TR-1). The results indicated that the Carrean is the beat model to describe the rheology of the ASP system. 1st Newtonian zone at low shear rate, sheaf thenning zone within medium shear rate, and 2nd Newtonian zone at high shear rate. The zero shearing viscosity decreased and shear thinning exponent increased with the increase of the concentrations of the con-
centrations of alkaline and surfactant.

Key words: Combination drive, Chemical flooding, Enhanced oil recovery, Rheological behavior
