Flue Gas-Simultaneous Water and Gas (Flue Gas-SWAG) Injection for Enhancing Oil Recovery

This paper discusses the possibility of utilization of exhaust (flue) gases by injecting them into the reservoir. Currently, injection of flue gases into the reservoir is not a widely used method for increasing oil production compared to CO2 or N2 injection. Most of technologies for injecting water-gas mixture using flue gas as a gas provide for water-alternating-gas injection. Only a few studies discuss simultaneous water-alternating-gas injection using flue gases. Moreover, there are few studies on creating a mixture of water and exhaust gases for co-injection by means of pump-ejecting systems into the reservoir. Therefore, in this work we propose a new improved diagram of the laboratory bench using exhaust (flue) gases to create a water and gas mixture for flue gas-simultaneous water and gas injection by means of pump-ejecting system. © 2022 Institute of Physics Publishing.
