The enhance oil recovery (EOR), nanotechnology, nanotechnology is emphasized due to cost effective and environmental aspects. Nano particle size for EOR is defined as 1- 1000 nm that would be differed compared to various international organizations. Comparing to same fine or bulk molecules, nano particles show different properties because of high concentration of surface atoms and ultra small size. One of the significant properties is creating massive diffusion driving force due to large surface area at high temperature. Based on previous studies, nanoparticles enhances oil recovery with shift reservoir wet ability toward more water- wet and reduction of interfacial tension. It is necessary to say potential of nanoparticles to reduce oil viscosity, increase of mobility rate and change permeability are areas that should be evaluated. Considering operational condition of EOR process, some nanoparticle performance is more effective they may be lead to various levels of enhancement recovery. In this research, we want to provide sum may about market nanoparticles and optimal operational condition. We categorized them to 3 groups of metal oxide, organic and inorganic particle.
