In this study, the dual-chamber pressure decay method and magnetic resonance imaging (MRI) were used to
dynamically visualize the CO2 diffusion process in n-decane, and the relations of concentration-distance for CO2 diffusing into oil at different times for CO2-oil system were obtained by quantitative analysis. A noniterative finite volume method was successfully applied to calculate the diffusion coefficient of CO2 in oil.
The results agreed very well with the conventional pressure decay method. According to the experimental
and calculating results, the relationship between the diffusion coefficients of CO2 in oil and CO2 concentration, diffusion distance, diffusion time and pressure during the process of CO2 diffusion in oil were discussed in detail.
