  • oil shale | National Geographic Society

    04.03.2013· Extracting and processing shale oil is an expensive and difficult process. Coal, petroleum, and natural gas are less expensive to extract. Australia, Brazil, Switzerland, Sweden, Spain, and South Africa began mining oil shale in the 19th and 20th centuries, but they all stopped production by the 1960s. The U.S. ceased production in the early 1980s.

    The Eocene Green River Formation of Colorado, Utah, and Wyoming contains the largest oil shale deposits in the world. Oil shale, despite the name, does not actually contain oil, but rather a type of organic matter called kerogen, a precursor of oil that is converted to a type of crude oil when heated to about 450 – 500° C.

    The extraction of oil shale through surface mining causes the general eco-impacts of open-pit mining. Meanwhile, the thermal processing generate harmful atmospheric emissions (such as carbon dioxide, a major greenhouse gas). It also results in combustion waste material, which requires proper disposal. Carbon capture, experimental in-situ conversion processes, and new storage technologies may

    History. Oil shale mining has not been around for a long time. In the 1970s the U.S. was already researching oil shale. However, oil shale production did not increase until later. The Energy Policy of 2005 directed the Bureau of Land Management (BLM) to lease its land for oil shale research and development. The leases were good for 10 years and could expand depending on whether the
