In the former ,CO 2, or N 2 are used to increase oil recovery. As shown in Figure 3 a) the carbon dioxide is injected at 1200 psi and density 5 lb/gal, it mixes with oil trapped into pores forming a concentrated mixture that goes back to the surface. Then, ,CO 2, is removed from the mixture, recompressed and injected again in the reservoir .
