... (1991) , which have been implemented in many commercial software packages, such as CMG/GEM and E300. Thus, we identify two clear mechanisms of oil recovery that may occur in near-miscible CO 2 (or other gas) injection which we denote as, M1 for oil stripping or compositional effects, and M2 for low-IFT...

... Figure 2 explains the changes in Kr curve during miscibility process. The immiscible Kr curve does not change but if it involves near or miscible gas injection, oil and gas compositions will vary and affect IFT and Kr. During this miscibility process the IFT will "progressively" reduce to zero, which...
