Introduction The global demand of energy is undergoing significant growth with the increase in world population technological advancement and industrial revolution over last years renewable energy have undergone significant development and been considered a candidate to replace fossil fuel energy Even though there has been more focus on renewable energy over the last years yet oil is still the main source of energy worldwide according to the international energy agency IEA Thus therefore there is a need to discover or recover more hydrocarbon to meet the world energy demand the application of different EOR method recover more oil from reservoirs by various mechanisms such as viscosity and IFT reduction wettability alteration enhancement of mobility ratio and sweep efficiency EOR application involve the injection of material and substances that change of physical and chemical properties of hydrocarbon and provide gravity drainage However throughout the years the traditional EOR processes have faced some challenges and limitation For example gas methods the injected gas often quickly penetrates through reservoirs from injection wells to producing wells resulting in a large amount of residual oil remaining uncovered in the application Chemical processes and agent are often limited by the high cost formation damages caused by injected chemical and losses of chemicals eg adsorption of surfactant into the reservoir rock
