... 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...

... is produced at water cuts of 90% or greater. Waterflood recovery is reduced for higher oil viscosities, but this can be partially compensated by means of larger volumes of injection water and reduced well spacing.

... production, while in solvent-diluted oil, if solvent comes out of solution as pressure drops, oil viscosity will increase again and one of the main benefits of the solvent will be lost. Solvent selection in CSI needs to consider which solvents have non-equilibrium properties, specifically delayed release...
