Enhanced Oil Recovery by Polymer Flooding

چکیده مقاله

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