Oil Shales under Dynamic Stress
The Los Alamos Scientific Laboratory has recently begun development of techniques to fracture oil-shale beds, hundreds of meters beneath the earth’s surface. The resulting shale fragment sizes must permit efficient in-place retorting of organic material from the shale. The initial phase of the program requires the determination of the properties of the shales under dynamic compression. These properties, and those of the proposed explosives, form the base for computer modeling of field events. The dynamic properties of oil shales and the experimental techniques used to determine them are discussed herein.
