چکیده

Recovery Factor is an important parameter in determining commercial viability of the oil Reservoirs. Wettability is a major factor that affects oil Recovery. Therefore, changing rock wettability may enhance oil recovery. In this paper, the effect of polysilicon nanoparticles on wettability change of Iranian carbonate reservoir is investigated. To assess this, hydrophilic changes of carbonate rocks are studied by using the contact angle test. Our results show that with increasing nanoparticle concentration, the contact angle decreases. In the next stage, the effect of adding nanoparticles on water flooding is studied. Our experimental results demonstrated that increasing the nanoparticle concentration up to 0.1 percent increases the recovery but further increase to 0.5 reduces the effect on recovery.
