Temperature effect on performance of nanoparticle/surfactant flooding in enhanced heavy oil recovery

Abstract Recently, nanoparticles have been used along with surfactants for enhancing oil recovery. Although the recent studies show that oil recovery is enhanced using nanoparticle/surfactant solutions, some effective parameters and mechanisms involved in the oil recovery have not yet been investiga...
