This paper describes numerically simulated reservoir performance during the injection of hot water and flue gas at North Sea reservoir conditions. Studies of hydrocarbon/water phase behaviour at elevated temperatures and reservoir simulations showed that a hot water flood in a light-oil reservoir could increase the recovery by 3-9 % of the- original oil in place. A theoretical study of flue gas injection concluded that minimum miscibility pressure (MMP) for this gas was equal to MMP for an oil/nitrogen system. A nitrogen displacement was estimated to be immiscible at initial reservoir pressure and temperature, but miscibility would be developed at a slightly higher temperature.
The results predict that the combination of hot water and flue gas injection has a substantial potential for increasing the recovery from light-oil reservoirs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
