... 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...

...) and API Gravity (12°). Then, coreflood tests were conducted by coinjecting steam with an anionic, a cationic, or a nonionic surfactant. The performance of three anionic, three cationic, and three nonionic surfactants was tested. Each core flood result was evaluated in terms of the cumulative oil recovery...

... under waterflood as indicated in Figures 4 and 5 Beliveau (2009). To maximize waterflood oil recovery from a viscous oil reservoir, it is important to inject large volumes of water and to handle large volumes of produced water along with the oil. Normally, 50% or more of the ultimate oil recovery...
