United States carbon dioxide injection

In the contiguous United States, the main emphasis is on miscible CO2 flooding. Carbon dioxide is relatively inexpensive since it has no value as a fuel and is available in large amounts from natural deposits or as a waste product of industrial processes. Table I shows major natural deposits of CO2, their approximate amounts, and their locations with respect to oil fields ( 1). With (or even without) partial recycling of CO2, there is no foreseeable shortage of this injection fluid.
