ABSTRACT
When the fluid inside of the reservoir has a high viscosity due to having a lower mobile ratio, therefore, water flooding is not suitable for oil recovery, and a system with a higher viscosity should be used. The emulsions have more viscosity, so in this system, in order to stabilize and optimize the viscosity of the system, chemical additives such as polymer and surfactant are used. These chemical additives damage the reservoir and the environment and lose their stability under high temperature, therefore, in this study; the emulsions stabilized with nanoparticles have been studied, and the effect of nonionic surfactant on wettability alteration was investigated, and various factors on the viscosity of this system have been determined.
