Brief Research Statement : Today, the energy demand across the globe is increasing at a rapid rate and to maintain the supply, the production of crude oil from reservoirs has to be enhanced, as majority of the energy demands are fulfilled by crude oil. During the production of crude oil, the natural pressure inside the reservoir declines which causes more than two third of the original oil in place resides in the pores of the reservoir rock. Therefore to recovery this enormous amount of crude oil advanced techniques is required. Chemical enhanced oil recovery (EOR) is one of the advanced techniques which came up with great potential in reducing the amount of residual oil saturation thus ultimately improving the oil recovery factor. However, the success of chemical EOR depends on several parameters which are highly complex and because of which no direct correlations are available. The mechanisms which are responsible for efficient residual oil recovery are the reduction in interfacial tension, emulsification, creaming index, wettability alteration, rheology and sweep efficiency. Chemical has adsorption characteristics which not only dilutes the optimum slug formation but also affects the economy of the process. Therefore nanoparticles are induced in the chemical slug not only to reduce the adsorption behavior but simultaneously improves the mechanisms responsible for higher oil recovery.
