Oil shale is a highly ash-rich sedimentary rock enriched with combustible organic matter [1], [2].The majority of the organic matter in oil shale is kerogen [3], [4], which is insoluble in common organic solvents [5], [6].The kerogen component is about 3% to 15% in oil shale, and consist of complex organic compound in high molecular weight [7], [8], that is rich in aliphatic …
Conversely, China faces challenges in oil shale mining due to a considerable portion of its resources being located at great depths, making the extraction process difficult and costly. For instance, operating costs range from 2400 yuan per ton in ore-bearing areas with shallow buried depths like in Huadian and Jilin, to 3600 yuan per ton in ...
Mining for oil shale can have damaging effects on the environment. When shale oil is combusted (heated), it releases carbon dioxide into the atmosphere. Carbon dioxide is a greenhouse gas; it absorbs and retains heat …
A novel method called oil shale in-situ mining technology is efficient and environmentally friendly. This technology can exploit deep oil shale while reducing pollution and greenhouse effect. Based on the data collected, this paper summarizes the development of global underground in-situ oil shale mining technology, introduces four

Piceance Creek runs through lands that are part of the Oldland Spur Ranch… No place in the world has more oil shale – an amount large enough to dwarf the proven oil reserves of Saudi Arabia – than the American West's Shale Country, the region that straddles the T-shaped border of Colorado, Utah, and Wyoming. And although daunting technical, economic, environmental, …
As the world's largest commercial oil shale reserve, the Estonian Oil Shale Deposit has been exploited since 1916. As a result of mining, storing of solid wastes from the oil shale separation, combustion in the power plants and its thermal processing, the landscape in northeastern Estonia has been essentially changed and the man-made landforms have …
The Oil-Shale Project . In . Pictures . PLANT NESTLES AT FOOT OF 'MOUNTJUN OF OIL' An aerial view (p. 7) shows the Oil-Shale Mine and Engineering Experiment Station of the Bureau of Mines, approximately 7 miles west of Rifle, Colo. From mines at the base of the cliffs, high above the juniper-clad slopes, oil shale is carried in trucks 5 %
Oil shale - Pollution, Mining, Energy: 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. Because oil and gas are produced by heating oil shale …
The Oil shale mining technology can be divided into traditional surface distillation technology and underground in-situ mining technology [8]. The primary way to develop oil shale is surface distillation. This method is to mine, transport, process, and refine oil shale from the surface or underground. However, this mode is only applicable to ...
Oil shale refers to sedimentary rock formations containing organic compounds known as kerogen, which can be processed to extract oil and gas. Despite its potential as an …
Natural oil shale's permeability and porosity is extremely low. When temperature is raised, its porosity will increase [2]. The oil shale resource in the world is tremendous. As the statistics published by the《Oil and Gas》showed, the reserve of the oil shale in the world is nearly trillion tons [3], which is far more than that of the ...
Shale Oil Processing and Extraction Technologies. Sohrab Zendehboudi PhD, Alireza Bahadori PhD, CEng, in Shale Oil and Gas Handbook, 2017. 2 Description of Oil Shale Processing. Shale oil processing is defined as an industrial process to which raw shale oil is subjected to extract oil from it—basically a process to produce unconventional oil [1].Because shale oil exists as solid …
A novel method called oil shale in-situ mining technology is efficient and environmentally friendly. This technology can exploit deep oil shale while reducing pollution and greenhouse effect. …
Oil Shale can only be found by Mining in the Desert biome. Oil Shale is placed into your Inventory when mining Oil Deposits. It has a purple hue and is somewhat shiny on higher graphic settings, with a brushed appearance as seen here as a Surface Node. Oil Shale is found in the Desert by digging down at about 20 blocks, where the stone layer begins. It is in the stone layer under …
Oil Shale and Tar Sands The United States holds more than half the world's oil shale, a fine-grained sedimentary rock containing organic matter from which petroleum products may be distilled. Although it has long been seen as a potential source of secure, reliable, and affordable energy, the technology to produce oil from oil shale in commercial quantities has been elusive.
Oil shale mining area is divided by two main mining methods, surface and underground methods. The reason for choosing underground or surface mining technology is overburden thickness, but historically and in the future other factors have strong influence as well (Valgma 2000).These are technology being used, economical situation, mining traditions and …
Oil shale is a type of sedimentary rock formation that can be used to produce oil and gas. Oil shale can produce oil and gas because of the presence of kerogen, a type of organic matter that...

The research results show that Maoming oil shale open-pit mine area has gone through four main stages: pre-exploitation stage, large-scale utilization stage, restoration stage, and green ...
The Rifle, Colorado, oil-shale project of the Bureau of Mines included three major divisions: (1) mining, (2) retorting, and (3) refining. The major functions of the mining program were to supply oil shale to the retorts, to devise mining procedures, and to develop an underground-mining method by which oil shale could be produced safely at an unusually low cost per ton.
oil shale, any sedimentary rock containing various amounts of solid organic material that yields petroleum products, along with a variety of solid by-products, when subjected to pyrolysis—a treatment that consists of heating the rock to …
There are now many proposed in-situ oil shale mining methods, but the principles of different in-situ oil shale mining technologies are similar. The general mining steps are as follows: First, the oil shale is fractured by injection of liquids at high pressure or high-temperature gas (Peng et al., 2018). This process not only increases the ...
According to our research, although the mining area has been restored, the environmental problems caused by years of large-scale oil shale mining are still continuing, coupled with the intensive distribution of the surrounding petrochemical industry, posing a serious threat to the local ecological environment (Ma et al., 2021).
The Esso Oil Company made a US$5 billion investment in a room-and-pillar type oil shale mine and a pilot-scale shale oil plant with the capacity to process 1000 tons of oil shale per day near Parachute Creek in the Piceance Basin in Colorado (Fig. 12). The "Colony Oil Project" began in 1964 and was operated by a consortium of different ...
