Enhanced Oil Recovery by Polymer Flooding

Chemical flooding is relies on the addition of one or more chemical compounds to aninjected fluid either to reduce interfacial tension between the reservoir oil and injectedfluid or to improve the sweep efficiency of the mobility ratio . Both mechanism aredesigned to increase the capillary number . In this article investigated the effect ofpolymer concentration in injection stream on some parameters such as : Polymeradsorption concentration , Polymer in solution , Water-Oil capillary pressure , Oilproduction total .
