Application of simultaneous water and gas injection technology for exhaust gas utilization and reduction of CO2 emissions

Abstract

In today's world, the energy sector has a major impact on the climate. In this process, the share attributable to oil and gas producers is large. The paper shows the prospects of reducing flaring of associated petroleum gas and carbon dioxide emissions by utilization of exhaust (flue) gases for injection into the reservoir to enhance oil recovery. The main industrial sources of exhaust (flue) gases are given. The scope of research on the use of exhaust gases in the development of oil fields with different properties is analyzed. The technology of simultaneous water and gas injection, aimed at the utilization of exhaust gases and increase oil recovery fields, is proposed. The technology of simultaneous water and gas injection is implemented with the use of pump-ejector systems and allows for the simultaneous injection of water and gas into productive formations. The main parameters of pumpejector system are determined for the conditions of a particular field. Keywords: exhaust (fuel) gases utilization; enhanced oil recovery (EOR); SWAG injection; pump-ejector system.
