The Effect of Nanoparticles Crystallite Size on the Recovery Efficiency in Dielectric Nanofluid Flooding

Application of nanotechnology in enhanced oil recovery(EOR) has been increasing in recent years. After secondary flooding, more than 60% of the original oil in place (OOIP)remains in the reservoir due to trapping of oil in the reservoir rock pores. One of the promising EOR methods is surfactant floo...
