Abstract
Enhanced Oil Recovery, or better known as EOR, is an alternative that can be done to increase the recovery of oil production in a field. One of the EOR methods that can be done is the injection of chemicals in the form of polymers. Polymer injection can reduce the mobility ratio between oil and water, because by adding polymer the viscosity of water will increase and the efficiency of driving oil by water will also increase. One of the many polymers developed is biopolymer. The use of biopolymers is considered to have several advantages, such as easy to obtain in nature, environmentally friendly, resistant to salinity and high temperatures. One of the bipolymers developed is chitosan. Chitosan is one of the biopolymers obtained from the deasitellation process of chitin which is found in many animal shells such as shrimp, crabs, crabs and oysters and other shelled animals.
