ABSTRACT
Overlay: The availability of oil is critical to the economies of the world. It is an essential ingredient for maintaining or increasing the standards of living for not only the 3 billion new persons coming in the next decades, but the existing 7 billion as well. The concern is the supply constraint that exists, and the rate of depletion of the world’s supply that may cause serious price instability and increases. The recent use of fracking of oil shale postpones for only a short time the problems of supply limitations.
