A Study about Diffusion Coefficient of Carbon Dioxide in Heavy Oil

Abstract:

CO₂ injection into oil reservoirs can both enhance oil recovery and realize CO₂ geological sequestration. The gas diffusion coefficient of CO₂ in oil and water is a very important factor for EOR. This paper developed a simple experimental technique for measuring the CO₂diffusion coefficient in heavy oil. In this paper, we find the relationship between initial pressure and diffusion coefficient and equilibrium pressure at the same temperature.
