Recently, nano-EOR has emerged as a new frontier for improved and enhanced oil recovery (IOR & EOR). Despite their benefits, the nanoparticles tend to agglomerate at reservoir conditions which cause detachment from oil/water interface, are consequently retained rather than transported through porous medium. Dielectric including ZnO have been proposed be good replacement EOR due high melting point thermal properties. But more importantly, these particles can polarized under electromagnetic...
