摘      要：Currently,the demand for using nanoparticles(NPs)in Enhanced Oil Recovery(EOR)is very *** use of NPs can drastically benefit EOR by changing the rock wettability,improving the mobility of oil phase and decreasing the interfacial tension(IFT)between oil/*** of the previous studies were experimentally conducted and limited to specific operating *** study contributes to the understanding of nanoparticle behaviour at altered operating *** this investigation,a 3-D numerical model of silica nanofluid proposed for EOR is presented.A numerical model of core-scale sandstone was developed using Computer Modelling Group(CMG)-STARS *** developed model was well validated against an experimental *** Silicon Dioxide(SiO_(2))and Sodium Dodecyl Sulphate(SDS)nano-surfactant mixture were injected with different *** optimum concentration of SiO_(2)eSDS solution was obtained at 0.15 wt%with the highest recovery factor of 71.86%***,SiO_(2)eSDS solution injection rate and temperature were investigated and it was found that the optimum operating conditions of injection rate and temperature were 2 cc/min and 60
C with the highest recovery *** addition,a heavy crude oil showed a significant increment of oil recovery compared with a light crude with 3.13%and 0.6%,*** intermediate viscosity of used crude oil had the highest oil recovery increment.
