Oil Shale. Not to be confused with shale oil, which is oil produced via horizontal wells and hydraulic fracturing, oil shale must be heated to high temperatures to convert the organic matter (kerogen) into usable oil.. Shale is a fine-grained sedimentary rock composed of mud containing clays and silt-size particles of other minerals.
At present, only the oil shales with the higher oil yields are used to obtain shale oil, about 25% of the total world oil shales mined. The remaining 75% is mainly used as a solid fuel in the generation of electricity and heat (69%) and for the production of synthetic domestic .
Oil shale shouldn't be confused with "shale oil," also called "tight oil," a more commonly produced type of unconventional oil that's found trapped in limestone or sandstone rocks. Because oil shale requires mining and energy-intensive refining processes, it's a substantially dirtier .
5 Shale Oil Companies With Best Prospects. ... The Eagle Ford region is of significant interest to energy companies, due to the fact that the area has more oil than other traditional shale plays ...

-Other Mineral Resources. Both minerals are commingled with high-grade oil shale in the deep northern part of the basin. Dyni (1974) estimated the total nahcolite resource at 29 billion tons. Beard and others (1974) estimated nearly the same amount of nahcolite and 17 billion tons of dawsonite.
What is 'Oil Shale'. Oil shale is a sedimentary rock formation containing kerogen. Kerogen is a type of organic matter that yields oil and gas and will burn when exposed to flame. The term shale covers a variety of sedimentary rock formations containing a combination of clay and other minerals.

Proposals to develop oil shale deposits. The Queensland Government considers that the moratorium on the McFarlane oil shale deposit should remain, given the potential impact on the Whitsunday region, key infrastructure, and proximity to the Great Barrier Reef World Heritage Area and the Goorganga Wetlands.
Oil shale may contain between 60 and 90% mineral matter (non-organic), while coal will contain, by definition, less than 40%. The kerogen within oil shale is also of different organic composition than coal, which enjoys a more matured organic makeup that is lower in .
Shale oil and gas are exactly the same products as oil and natural gas from conventional extraction. Oil and gas are chemicals made just of two elements: carbon and hydrogen. The microscopic plants and animals that lived in the ocean millions of years ago sank to the bottom of the sea.
In both of thesemining areas, research will be carried on to develop new and improved practicesfor mining oil shale. Introduction. Oil shale is a sedimentary rock containing a solid mineraloid of indefinitecomposition known as kerogen. On heating oil shale, the kerogen undergoesthermal decomposition and some of the vapor products of the decomposition canbe condensed as shale oil.
The USGS Energy Resources Program has studied oil shale resources of the United States, with a significant effort on the Eocene Green River Formation of Colorado, Utah, and Wyoming. This formation contains the largest oil shale deposits in the world.
Oil shale - Oil shale - Environmental issues: The production of oil from shales has a potentially serious impact on the environment. Four specific areas of concern dominate discussion regarding development of the resource: greenhouse gas output, water consumption and pollution, surface disturbance, and socioeconomic effects.
Oil Shale Resources. Shale is a fine-grained sedimentary rock composed of mud containing clays and silt-size particles of other minerals. Some shale can also contain significant amounts (5% or more) of organic matter—the fossil remains of protozoans, microscopic animals, or plants—called kerogen.

One of oil shale mining by-products is limestone waste. To prepare a trade product of oil shale, the separation of limestone from mined rock in special mills is necessary. As a result there are 32 waste piles near oil shale separation mills, which consist mainly 82-94 % limestone and 6-18 % residual oil shale 7.
Shale-focused peer Pioneer Natural Resources (NYSE:PXD), ranked as Texas' second-largest oil producer in 2016, pulling 167,006 barrels per day from the Eagle Ford and Permian formations -- 6.3% of Texas' production. It was also the tenth-largest natural gas producer in .
Oil shale mining in Estonia Selective mining improves quality in oil shale extraction. Oil shale is a type of rock consisting of both organic carbon and mineral constituents. Oil shale resources are estimated to amount to some 10 quintillion tonnes worldwide.
Oil shale - Oil shale - Surface processing: Four basic steps are involved in the aboveground processing of oil shale: mining the ore (either through underground or surface mining), crushing the ore to a size that can be handled by the retort, retorting (heating) the crushed shale to pyrolysis temperatures, and upgrading the oil obtained by pyrolysis of the organic content of the shale.
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.
Shale oil and gas are exactly the same products as oil and natural gas from conventional extraction. Oil and gas are chemicals made just of two elements: carbon and hydrogen. The microscopic plants and animals that lived in the ocean millions of years ago sank to the bottom of the sea.
There have been a few energy booms in the United States over the years and many of them have been associated with the oil shale industry. Unlike other fossil fuels, oil shale creates petroleum products by extracting oil out of shale deposits that are buried relatively close to the soil surface. With improving technology and [.]
Oil shale is a type of rock that consists of organic carbon and minerals. It is generally a sedimentary rock that contains solid kerogen. Surface mining is one of the main methods of recovering this oil shale. Surface mining is when the areas of kerogen rock are stripped away using heavy equipment and carried to a refinery as shown in Fig. 3.5. Blasting or cutting is used to break up the rock surface, and then the .
Oil shales range widely in organic content and oil yield. Commercial grades of oil shale, as determined by their yield of shale oil, ranges from about 100 to 200 liters per metric ton (l/t) of rock. The U.S. Geological Survey has used a lower limit of about 40 l/t for classification of Federal oil-shale lands.
Oil shale or liquid-rich shale generally refers to any sedimentary rock that contains solid bituminous material called kerogen that is released as a petroleum-like liquid when the rock is heated in the chemical process of pyrolysis. Oil shale has been used as an energy source for centuries.
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 Scottish shale oil industry has a remarkable and important history. Bathgate Chemical Works, established in 1851, was perhaps the first site in the world where mineral oils .

Oil shale must be mined using either underground- or surface-mining methods. After excavation, the oil shale must undergo retorting. This is when the mined rock is exposed to the process of pyrolysis -- applying extreme heat without the presence of oxygen to a substance, and producing a chemical change.
Oil suppliers and OPEC play a large role in the production and price of oil. Oil shale can be used to make diesel fuel, gasoline, and liquid petroleum gas. These energy sources can be used to power machines such as cars, lawnmowers, generators, etc. Mining process. .
