  7. Abstract:
  8. In recent years, carbon dioxide is used for enhanced oil recovery of heavy oil. Steam Huff and Puff is one of the enhanced oil recovery methods used for heavy oil. In this study liquid CO2 was used as an injecting fluid instead of steam. In this paper a series of experiments were performed to demonstrate the effect of carbon dioxide injection pressure on huff and puff process. The experimental data are used in lab scale model simulated with commercial simulator Eclipse 300 to investigate the effect of soaking time, injection pore volume and rate of injection on the heavy oil recovery. Result of experiments showed that huff and puff process under miscible pressure condition gives the most recovery and injection under immiscible condition gives the lowest one. Simulation results illustrated that, there is an optimum value for soaking time that for soaking times less than this value, recovery increases, and for values greater than optimum the recovery decreases. Simulation study demonstrated that oil recovery increases with increasing volume of injected miscible fluid and recovery decreases with injection rate increase
