ABSTRACT Vast amounts of world oil reservoirs are in natural fractured reservoirs. There are different methods for increasing recovery from fractured reservoirs. Miscible injection of water alternating CO 2 is a good choice among EOR methods. In this method, water and CO 2 slugs are injected alternatively in reservoir as miscible agent into reservoir. This paper studies water injection scenario and miscible injection of water and CO 2 in a two dimensional, inhomogeneous fractured reservoir. The results show that miscible water alternating CO 2 gas injection leads to 3.95% increase in final oil ...
