Shale Technologies (company)
Shale Technologies, LLC is an American privately held oil shale company with headquarters in Rifle, Colorado. It is an owner of the proprietary information relating to the Paraho oil shale retorting technologies (Paraho Direct and Paraho Indirect). The Paraho Direct is an American version of a vertical shaft retort similar to the Kiviter and Fushun retorts. This technology is used in the company's pilot plant facility in Rifle. History On 28 June 2000, Shale Technologies purchased Paraho Development Corporation, a developer of shale oil extraction technology.

Oil Shale
Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced. In addition to kerogen, general composition of oil shales constitutes inorganic substance and bitumens. Based on their deposition environment, oil shales are classified as marine, lacustrine and terrestrial oil shales. Oil shales differ from oil-''bearing'' shales, shale deposits that contain petroleum (tight oil) that is sometimes produced from drilled wells. Examples of oil-''bearing'' shales are the Bakken Formation, Pierre Shale, Niobrara Formation, and Eagle Ford Formation. Accordingly, shale oil produced from oil shale should not be confused with tight oil, which is also frequently called shale oil. Deposits of oil shale occur around the world, including major deposits in the United States. A 2016 estimate of global deposits set the total world resources of oil shale equivalent of of oil in place. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifle, Colorado
Rifle is a List of municipalities in Colorado#Home rule municipality, home rule municipality in and the most populous community of Garfield County, Colorado, Garfield County, Colorado, United States. The population was 10,437 at the 2020 United States Census, 2020 census. Rifle is a regional center of the Ranch, cattle ranching industry located along Interstate 70 in Colorado, Interstate 70 and the Colorado River just east of the Roan Plateau, which dominates the western skyline of the town. The town was founded in 1882 by Abram Maxfield, and was incorporated in 1905 along Rifle Creek, near its mouth on the Colorado. The community takes its name from the creek.''Rifle Shots: The Story of Rifle, Colorado'', compiled by the Reading Club of Rifle, Colorado, 1973. History The land that Rifle resides on was once in the heart of the Ute people, Ute Nation, a classification of the Indigenous peoples of the Great Basin. The most common tribe in the area were the Tabagauche, who hunted a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraho Process
The Paraho process is an above ground retorting technology for shale oil extraction. The name "Paraho" is delivered from the words "''para homem''", which means in Portuguese "for mankind". History The Paraho process was invented by John B. Jones, Jr., later president of the Paraho Development Corporation, and developed by Development Engineering, Inc., in the late 1960s. Its design was based on a gas combustion retort developed by the United States Bureau of Mines and the earlier Nevada–Texas–Utah Retort. In the late 1940s, these retorts were tested in the Oil Shale Experiment Station at Anvil Points in Rifle, Colorado. In 1971, the Standard Oil of Ohio started to cooperate with Mr. John B. Jones providing financial support for obtaining an oil shale lease at Anvil Points. In May 1972, the lease was approved. Before leasing a track at Anvil Points, a test of using the Paraho Direct process for limestone calcination in cement kilns was carried out. The consortium fo ...

Kiviter Process
The Kiviter process is an above ground retorting technology for shale oil extraction. History The Kiviter process is based on the earlier vertical retort technology (Pintsch's generator). This technology underwent a long process of development. The early concept of central inlet of the heat carrier was later replaced by a concept of heat carrier gas cross flow in the retort. The Kiviter technology has been used in Estonia since 1921, when first experimental Kiviter retorts were built. The first commercial scale oil plant based on the Kiviter technology was built in 1924. From 1955 to 2003, Kiviter technology was used for oil shale processing also in Slantsy, Russia. Technology The Kiviter process is classified as an internal combustion technology. The Kiviter retort is a vertical cylindrical vessel that heats coarse oil shale with recycled gases, steam, and air. To supply heat, gases (including produced oil shale gas) and carbonaceous spent residue are burnt wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fushun Process
The Fushun process is an above-ground retorting technology for shale oil extraction. It is named after the main production site of Fushun, Liaoning province in northeastern China. History The Fushun process was developed and utilized for the extraction of shale oil in China during the mid-1920s. The commercial-scale utilization of the process began in 1930 with the construction of "Refinery No. 1". After World War II, the shale oil production was ceased, but 100 Fushun-type oil shale retorts were restored in 1949. In 1950, total 266 retorts were in operation, each with the capacity of 100–200 tons of shale oil per day. With the discovery of Daqing oil field in the 1960s, the shale oil production declined and Sinopec, an operator of shale oil production these times, shut down its oil shale operations in the beginning of the 1990s. At the same time, the Fushun Oil Shale Retorting Plant, using Fushun process technology, was established as a part of the Fushu ...

Shale Oil Extraction
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 impurities. Shale oil extraction is usually performed above ground (''ex situ'' processing) by mining the oil shale and then treating it in processing facilities. Other modern technologies perform the processing underground (on-site or ''in situ'' processing) by applying heat and extracting the oil via oil wells. The earliest description of the process dates to the 10th century. In 1684, Great Britain granted the first formal extraction process patent. Extraction industries and innovations became widespread during the 19th century. The industry shrank in the mid-20th century following the discovery of large reserves of conventional oil, ...
