Nitrogen Injection into Fractured Reservoir

A simulation study was conducted using Eclipse reservoir simulator for nitrogen injection into a naturally fractured reservoir. Both homogenized permeability and dual porosity models were used to represent the reservoir for the gas injection process. A comparison between the black oil and compositional gas was also performed to adequately represent the production conditions of the field. Other simulations included the impact of a mixture of gases such as reservoir gas and methane on recovery.
