Experimental Study of Solvent Based Emulsion Injection to Enhance Heavy Oil Recovery
This study presents the results of nano-particle and surfactant-stabilized solvent-based emulsion core flooding studies under laboratory conditions that investigate the recovery mechanisms of chemical flooding in a heavy oil reservoir. In the study, bench tests, including the phase behavior test, rh...
