The properties of raw shale oil vary depending on the composition of the parent oil shale and the extraction technology used. [29] Like conventional oil, shale oil is a complex mixture of hydrocarbons, and is characterized according to the bulk properties of the oil.
The properties of raw shale oil vary depending on the composition of the parent oil shale and the extraction technology used. [63] Like conventional oil, shale oil is a complex mixture of hydrocarbons, and it is characterized using bulk properties of the oil. Shale oil usually contains large quantities of olefinic and aromatic hydrocarbons
Tight oil formations include the Bakken Shale, the Niobrara Formation, Barnett Shale, and the Eagle Ford Shale in the United States, R'Mah Formation in Syria, Sargelu Formation in the northern Persian Gulf region, Athel Formation in Oman, Bazhenov Formation and Achimov Formation of West Siberia in Russia, Arckaringa Basin in Australia, Chicontepec Formation in Mexico, [1] and the Vaca Muerta ...
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]
The shale drilling techniques that led to a boom in oil and gas output have also spurred the development of geothermal, which in theory could provide a stable source of power equal to the demand ...
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 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 process heats sections of the vast oil shale field in situ, releasing the shale oil and oil shale gas from the rock so that it can be pumped to the surface and made into fuel. In this process, a freeze wall is first to be constructed to isolate the processing area from surrounding groundwater. [ 1 ]
