Abstract: In this paper,an efficient finite element method is presented for a two dimensional,two phase nonliear model of polymer flooding The associated computer program is designed and a simulation using some data of a "five point well pattern was carried out.It is shown that polymer flooding can increase the production efficiently and greatly as compared to water flooding.But proper polymer slug size should be selected in view of economy.It is demonstrated that finite elment method can be used in the simulation of polymer flooding.
