    Abstract:

    In this paper, gas injection will be studied in a gas condensate reservoir to increase the recovery factor, and moreover the capability of different injection gases (CO2, N2, CH4 and separator gas) will be compared through different injection schemes. The injection schemes that will be considered are: different injection rates, different injection pressures and different injection durations. We think that the response of the reservoir in different cases will be different but that injection of all of them can increase the condensate recovery. As many parameters can affect the decision of selecting the injection scheme, other than the gas and condensate recovery factor, doing an economical evaluation is inevitable to take them all into account and determine the best one.
    In this paper, the efficiency of different schemes of gas injection and gas recycling in condensate recovery from a gas condensate reservoir, through compositional simulation has been studied and compared. The effect of changing injection rate, injection pressure and injection duration have been investigated by three injection gases (N2, CO2, CH4) and gas recycling. The appropriate and optimum case can be selected considering the results of the simulation work and doing an economical evaluation, taking into account all the parameters such as: the price of the gas and condensate, the price of the injection gases and the cost of the facilities needed in each scheme with regard to the present level.
