... al ., 2007 ; Newcombe et al ., 1955 ). This is not the case when oil viscosity is low. Also, this velocity-induced improvement in late time oil recovery is more pronounced in the more viscous oil systems, which could be a strong evidence proving the significance of imbibition phenomenon in viscous...

Abstract Dispersion of a solvent into heavy oil and bitumen in porous media has special significance in the context of solvent-based as well as solvent-aided versions of SAGD and CSS recovery processes. While solvent is injected with steam, the mixture...
