... Abstract For a thin oil rim reservoir with a large gas cap on top and a strong aquifer below, the art of optimizing the oil recovery is to keep the oil rim in continuous contact with the producing wells in the oil rim. Therefore, the management of gas-oil contact and water-oil contact movement...
