Abstract

The minimum miscibility pressure (MMP) determines the main mechanism of CO 2 flooding, which is either an immiscible or miscible process. This paper examines the recovery improvements of CO 2 flooding in terms of both the injection temperature and solvent composition. The results show that a lower temperature injection and LPG (liquefied petroleum gas) mixture can considerably improve oil recovery due to the reduced MMP in the swept area caused by the injected solvent. For the pure CO 2 injection at the reservoir temperature, oil recovery is 59% after 1.0 PV CO 2 injection. The oil recoveries by CO 2 -LPG mixtures are improved to 73% with 0.1 mole fractions of LPG and 81% with 0.2 mole fractions of LPG. The recovery factor from low-temperature CO 2 injection is 78%, which is 32% higher compared to the isothermal case. The recoveries obtained by low-temperature CO 2 -LPG injection increase up to 87% of the initial oil. Heat transfer between the reservoir and the formation of over/underburden should be considered in order to describe the process more accurately. Additionally, the recovery factors from the heat transfer models are decreased by 4–12% in comparison with the original nonisothermal models.
