In 1997 year 6 mines and 3 opencasts mined in total 22 Mtons of oil shale. After partial enrichment 14.4 Mtons of oil shale was sold to make electricity (2 power plants), shale oil and gas (3 processing plants), and heat. Oil shale mining imparts a variety of impacts on the environment.
John R. Dyni, in Encyclopedia of Energy, 2004 1 Introduction. Oil shale is a low-unit-cost energy commodity that requires mining and retorting thousands of tons of oil shale per year to achieve profitability. For example, one short ton of a commercial grade oil shale from the Green River formation in Colorado assays about 35 U.S. gallons of shale oil per short ton of rock (approximately 145 ...
Utah oil shale mining claims, to be discussed later, were settled in 2009. Today the federal government contends that all pre-1920 unpatented oil shale mining claims are no longer valid. Development Activities Shortly after 1915, developers began building small pilot plants to process oil shale, believing that eventually this

Maoming oil shale mine started operation in the 1960s, and stopped in the 1990s due to the shutting down of the Maoming retorting plant. TE SS In Brazil, open pit mining has been carried out for producing oil shale, about several thousand tons daily, for Petrosix retorting. S R In USA, oil shale was exploited, but only used for pilot plant or ...
The main idea of this article is to substantiate the expediency of revival of the oil shale industry in Russia. Data on the UTT-3000 plants' advantages, shale oils, and gas properties is provided. Information on investments in an UTT-3000 plant and estimated cost of Leningrad oil shale mining at the Mezhdurechensk Strip Mine is given.
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 oil shale industry is an industry of mining and processing of oil shale—a fine-grained sedimentary rock, containing significant amounts of kerogen, from which liquid hydrocarbons can be manufactured. The industry has developed in Brazil, China, Estonia and …
In addition, it results in increasing oil yield, decreasing CO2 pollution, decreasing ash amount, decreasing oil shale losses, avoiding vibration caused by blasting, avoiding ground surface subsidence (in the case of longwall mining), increasing drifting and extracting productivity compared with current room-and-pillar mining and increasing ...
Unlike conventional oil, shale oil cannot be recovered by drilling; it requires heating for oil to be released 3. There are two methods of recovering shale oil – ex-situ and in-situ processing. In ex-situ processing, shale oil is mined with conventional mining methods, like open pit, strip or underground mining.
Enefit will run the oil shale it mines through its processing plant and pipe the resulting synthetic crude to petroleum refineries in Salt Lake City and beyond. In the long term, Enefit aims to expand its mining operations onto federal public lands next-door by vastly expanding its current oil shale lease from the Bureau of Land Management (BLM).
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.
The facility is located on the Naval Oil Shale Reserve near Rifle, Colorado. A $9 million, 34 month, mining, retorting and disposal program is scheduled for completion by mid 1976. A large pilot plant and a semi-works scale plant were erected and put into operation in 1974. Two modes of operation, direct and indirect heating, have been ...
Graham's and White River beardtongues are found only in oil shale outcroppings in northeastern Utah's Uinta Basin and northwestern Colorado's Piceance Basin. This badland region is home to dozens of rare plants found nowhere else in the world and supports a complex ecosystem, including mule deer, elk, antelope, mountain lions and black bears.
Shale oil is the product of the thermal reaction and decomposition of kerogen present in oil shales. Any technology to produce shale oil includes mining, heat treatment—also known as retorting—to extract the oil, and oil upgrading. Mining oil shale can be either surface mining or in situ retorting.
Oil Shale It's important to distinguish between oil sands and oil shale. Both are present in the Uinta Basin, but of the two, oil shale is by far more plentiful. The US Geological Survey estimates that, if fully exploited, there is enough oil shale in the basin to yield 1.32 trillion barrels of oil.
A range of geological parameters relevant to mining oil shale have been examined for the Mahogany zone of the Green River Formation in the Piceance Basin, Colorado, and Uinta Basin, Utah, using information available in the U.S. Geological Survey Oil Shale Assessment database.

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.
Knowing the accurate production of material flows and collections one can draw a final layout for the separation plant. Results In the case of non-selective mining, oil shale has to be processed in a concentration plant to achieve the desired quality for customers. Oil shale is concentrated in heavy media separation drums.
