This chapter describes the different methods and the application of gas injection in the oil and gas industry and environmental purposes. For this purpose, first the worldwide hydrocarbon distribution is studied which categorized as conventional and unconventional resources. Also, the graphical distribution is reported using the latest statistics of conventional and unconventional hydrocarbon resources. Second, the steps of recovery of oil reservoirs are studied which consist of primary, secondary and tertiary oil recovery. Gas injection is performed for improvement of oil recovery in the secondary and tertiary oil recovery. Environmental protection and reduction of greenhouse gases is another goal of gas injection. Third, various relevant aspects including, historical evolution, screening criteria, sources of gas and economic of gas injection are investigated. |
