First we have established the testing method of CO2-crude oil system molecular diffusion tests, and then have carried out experimental tests in PVTcell and porous medium respectively.
In both cases the volume of the first appeared fluid at the bottom of PVTcell is relatively small, and the pressure at which the first fluid disappears is of the same value at different temperatures.
