| Abstract | Many gas-condensate reservoirs contain adequate amount of condensate even when they are considered as depleted. Increasing the condensate production from gas-condensate reservoir is always seemed to be challenge for E&P companies. When the reservoir pressure drops below the dew point pressure condensate condenses into liquid. Small pores of reservoir has tendency to trap these valuable tiny drops of condensate. The tiny drops of condensate are not only loss of condensate production but also cause the blockage of gas flow. An alternative approach to solve this problem is CO2 injection. CO2 injection technique enhanced the condensate production by keeping the reservoir pressure above the dew point. This study investigated the different scenarios of CO2 injection to maximize the condensate production by using the compositional simulator. A simple hypothetical reservoir model is constructed and initial reservoir conditions, fluid composition and fluid properties are used in the simulation. Different production and injection strategies namely, production with natural depletion, production with CO2 injection, effect of CO2 injection time on condensate production, effect of reservoir thickness with CO2 injection on condensate production and effect of permeability with CO2 injection on condensate production are simulated. The study concluded that CO2 injection is an optimal strategy to enhance the condensate production from gas-condensate reservoir effectively. |
