... potential for oil and gas recovery. In this study, a special type of polysilicon nanoparticle (HLP, Hydrophobic and Lipophilic Polysilicon) is investigated as an EOR agent during different water injection scenarios. The water-wet sandstone core samples are employed. Injection of HLP nanoparticle dispersed...

..., 2010 ). In this study we plan to find the dominant mechanism in Nano-fluid injection in case of EOR processes. To do such, water and Nano-fluid are injected through the core sample saturated with a light crude oil. Then by obtaining the production results and use of relative permeability methods...

... phase were investigated. Then, several coreflood experiments were conducted to study their impacts directly on recoveries. Furthermore, optimum pore-volume injection of each Nano-fluid was determined according the pressure drop across the core samples. The results show a change toward less water-wet...
