Oil Shale Will Demand Efficient Materials Handling 690364
The state of the art for in situ methods is not sufficiently developed for commercial recovery of oil from shale, and therefore underground room and pillar mining will probably be the first methods used. However, this will involve equipment that is associated with large scale, open pit mining. Practically all investigations of commercial oil extraction have been confined to relatively thin strata in a small area held by private firms because the formations that range from 1000-2000 ft thickness lie within public lands and are not open to leasing. This paper describes present commercial resources, methods used in extracting oil from shale, and projected development.
