... the recovery of heavy oil reserves, such as those of Western Canada, has not been given enough attention due to immiscible nature of the mixture of CO 2 and these heavy oil resources. Many heavy oil reservoirs in Western Canada have been under waterflooding where oil is produced at very high water-oilratios...

... and swelling clays, such as kaolinite and montmorillonite(3,4). Due to the presence of these clays, the formation is sensitive to fresh water and this has hampered efforts to improve oil recovery by waterflooding. 2 Organic (waxes and/or asphaltenes) solid precipitation is another major factor hindering oil...

The results of these experiments show that high polymer concentrations, i.e. more than 5000 ppm, are required in order to improve oil recovery, beyond waterflooding, from a porous media with residual heavy oil saturation. Additionally...
