What Is Wrong With Oil Shale?

WHAT is wrong with oil shale? The answer is of interest to the public, to the oil refiner, and to the engineer. Many people have invested in shale land or shale securities, and others would invest if early development of the industry were certain. In the face of increasing demands for oil products, oil refiners are threatened with inability to maintain present output unless the supply of domestic petroleum is supplemented. Development of the oil shale industry would open a new field for engineering services. The object of this paper is to suggest reasons why there is but one shale plant in operation in the United States, and to discuss the probable time when the business will be firmly established in Colorado. As the Colorado deposits are the richest and largest in the world, ample supply of material is assured, consequently, this discussion will be confined principally to technical problems and economic problems affecting shale development.
