The oil shale industry expanded immediately before World War I because of limited access to conventional petroleum resources and the mass production of automobiles and trucks, which accompanied an increase in gasoline consumption. [48] Oil shale production in Scotland peaked in 1910–1912 with more than three million tonnes. [14]
The history of the oil shale industry in the United States goes back to the 1850s; it dates back farther as a major enterprise than the petroleum industry. But although the United States contains the world's largest known resource of oil shale, the US has not been a significant producer of shale oil since 1861.
The oil shale industry is an industry of mining and processing of oil shale—a fine-grained sedimentary rock, containing significant amounts of kerogen (a solid mixture of organic chemical compounds), from which liquid hydrocarbons can be manufactured.
The global oil-shale industry began to revive at the beginning of the 21st century. In 2003, an oil-shale development program restarted in the United States. Authorities introduced a commercial leasing program permitting the extraction of oil shale and oil sands on federal lands in 2005, in accordance with the Energy Policy Act of 2005. [50] [51]
Other Tasmanian oil shale operations were carried out by the Railton-Latrobe Oil Shale Company, the Southern Cross Motor Fuels Company, and the Tasmanian Cement Company. [4] After the 1973 oil crisis, several companies explored the oil shale resources of Eastern Queensland; however, these activities diminished by 1986 after a drop in oil prices ...
Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution. The resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen ...
The Fushun oil-shale and coal deposit of Eocene age is located in north-eastern China, south of Fushun, Liaoning. Coal and oil shale are in a small outlier of Mesozoic and Tertiary sedimentary and volcanic rocks underlain by Precambrian granitic gneiss. The thickness of the layer of oil shale varies from 48 metres (157 ft) to 190 metres (620 ft ...
Outcrop of the Messel oil shale near the center of the pit. Brown coal and later oil shale was actively mined from 1859. The pit first became known for its wealth of fossils around 1900, but serious scientific excavation only started around the 1970s, when falling oil prices made mining the quarry uneconomical. Commercial oil shale mining ...
