Abstract
This paper reports a laboratory study on the use of natural polymers to in-crease oil recovery. The natural polymers used are shrimp chitosan, crab chi-tosan, Cyclea barbata Miers, Mesonapalustris, and seaweed. The aqueous solution stability test showed that all polymer solution samples were clear for various concentrations and salinities. Except for the solutions of Cyclea barbata Miers and Masona palustris which are greenish and blackish respec-tively. Transmittance for shrimp and crab chitosan solutions shows a value of more than 80%. This shows that natural polymers are compatible with brine. Flooding tests were carried out to measure oil recovery related to the use of natural polymers. The experimental results showed that the best ad-ditional oil recovery was 10.3% using crab chitosan solution injection. The chitosan solution used had a concentration of 15,000 ppm and a viscosity of 1,729 cp.
