The application of (CO2) miscible gas displacement at a minimum miscible pressure causes the reduction of fluid viscosity and lowers the interfacial tension between the reservoir fluid and injected gas thereby enhancing maximum fluid recovery at the time when the reservoir energy is stunted. There are usually parameters that affect the minimum miscibility pressure (MMP) in such way that gas and reservoir fluids are mixed together in single homogeneous phase. These parametersas discussed herein are analyzed using PVTi, Eclipse 300 simulation software. The software utilized Peng-Robinson equation of state model (PR3) to create an injection environment and analyze necessary parameters that affect MMP. The simulation results showed that MMP increases as temperature increases and decreases as reservoir fluid composition moves from light to heavy fluid. Observations also showed that MMP increases with increase in mole percent of injected gas (CO2). It is therefore important to effectively analyze and control parameters affecting MMP in order to achieve maximum recovery of reservoir fluid, dependent on operators’ discretions.
