Abstract:
Gas injection in oil reservoirs causes the oil to be directed towards production wells and the amount of oil recovery in the reservoir increases by changing the thermodynamic properties of the reservoir fluid. In this paper, the effect of natural gas injection in a normal oil reservoir has been studied and the changes obtained on the fluid properties of the reservoir due to this injection have been investigated. For this purpose, first, the properties of primary reservoir fluid have been studied. Then, properties of current reservoir fluid which were achieved by PVT tests have been studied. Phase behavior of current reservoir fluid was compared with phase behavior of primary reservoir fluid. It was found that phase behavior of reservoir fluid has been changed due to gas injection into this reservoir.
