Heavy crude oil is one of the unconventional crude oil which is difficult to recovery from the reservoir formation. Chemical flooding is a non-thermal flooding method which uses synthetic chemical for the recovery of heavy oil. Anionic and non-ionic surfactants such as Sodium dodecyl sulphate, tween were performed in some of the heavy oil fields and found to be effective. Polymer flooding namely Arabic gum, polyacrylamide has potential in the recovery of heavy oil. In the laboratory scale, Alkaline-Surfactant-Polymer was tested in the core flooding apparatus and macro emulsion was formed with the heavy oil samples.
