CO2 Sequestrated EOR

1. Whether, light components in crude oil contribute to miscibility?

2. Whether, the light components in the crude oil are continuously vaporized into the gas phase during contact with CO2?

3. Whether, the oil components undergo mass transfer between phases?

4. Whether, the mass transfer of the primary component (C2–C6) promotes the mass transfer of the “next” primary component (C7–C15) and ultimately promotes the mass transfer of the heavy component (C16+)?

5. Whether, the C2–C6 components in crude oil remain to be the key components that determine the miscible phase?

6. Whether, C6–C15 remain to be an important component affecting the miscibility of oil–CO2?
