World energy demand continues to increase, as they evolve, and developing countries consume more energy to keep their rising factories going. A significant portion of the energy demand is supplied by fossil fuels, especially crude oil. Therefore, in order to satisfy the world's energy demand, oil reserves and oil production capability must be increased. This objective can be accomplished by enhancing the recovery efficiency of the existing generating or mature reservoirs through the application of increased oil recovery. The injection of fluids into oil reservoirs has the purpose of supplementing natural energy and is used in some cases to engage with the reservoir's rock/oil system, standardizing for oil recovery, such as lower interfacial stress, oil swelling, reduction of oil viscosity and adjustment of wettability.
Subject to comprehensive studies, in heavy oil reservoirs, polymer injection is not dependent on large technological instruments, requiring only mixing and filtration equipment, except for those already used for traditional water injections. In addition, polymers are non-toxic and corrosive and can produce desirable mobility ratios. The implementation of this approach decreases the output ratio of water to oil, thus decreasing operating.
In the present work, thirty-five data points from experimental work had been investigated to develop a new correlation for viscosity of water by using the suitable program. It was analyzed the influence of the polymer additives on the mobility ratio, temperature and concentration effect on mobility ratio, and viscosity altering with the additives have been investigated. The results of the correlation showed acceptable agreement between the observed and predicted viscosity values. As a contrast to the polymer
additives approach, pure water was proposed.
