<p>A method for the recovery of oil or other hydrocarbon deposits from a subterranean formation below a surficial formation, said method comprising the steps of: a) Providing production water, said production water having a first salinity; b) Processing said production water to form an aqueous fluid having a salinity lower than said first salinity; c) Injecting said processed aqueous fluid into the subterranean formation sequentially either prior to and / or subsequent to the injection of a second fluid into said formation; and, d) collecting hydrocarbons displaced by the injected fluids, wherein in said method, said second injected fluid comprises carbon dioxide.</p> |
