Polymer Flooding for Enhanced Oil Recovery

Polymer flooding has been used for more than 40 years to effectively recover the remaining oil from the reservoir, up to 30% of the original oil in place. Due to decreased water production and enhanced oil production, the total cost of using the polymer flooding technique is less than that of water flooding.
