Nevertheless, U.S. production of shale oil has increased significantly since 2010, driven by technological improvements that have reduced drilling costs and improved drilling efficiency in major shale producing areas, such as the Bakken, Eagle Ford, and the Permian Basin. Depositsof oil shale occur around the … George P. Mitchell pioneered modern shale drilling, which combined the decades-old technologies of hydraulic fracturing, or fracking, and horizontal drilling to crack open shale rock and tap into previously inaccessible reservoirs of crude and natural gas. Crude oil production in the U.S. shale patch is set to decline by 68,000 bpd next month, with every play registering declines in output except the Permian ‘The targets are oil, coal, shale oil, and, if you believe the oil industry's press releases, the largest trove of natural gas on the continent.’ ‘The first oil refinery in Australia to contain a catalytic cracking unit was at Glen Davis, producing 160000 barrels a day of crude shale oil.’ Fracking is a slang term for hydraulic fracturing. 54–56.

The resulting oil can be used immediately as a fuel or upgraded to meet refinery feedstock specifications by adding hydrogen and removing impurities such as sulfur and nitrogen. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. The differing properties of the raw oils call for correspondingly various pre-treatments before it can be sent to a conventional oil refinery. Shale oil is made possible thanks to advances in horizontal drilling and fracking. What does oil shale mean? It is generally less economical than conventional crude oil. The offers that appear in this table are from partnerships from which Investopedia receives compensation.

Decomposition takes place most quickly at a temperature between 480 and 520 °C (900 and 970 °F). [29] Like conventional oil, shale oil is a complex mixture of hydrocarbons, and it is characterized using bulk properties of the oil. These processes convert the organic matter within the rock (kerogen) into synthetic oil and gas. See more. This has allowed companies to start extracting oil and gas from less-permeable rocks such as shale, opening up vast new fields collectively called unconventional reservoirs. [7] Shale oil was used to light the streets of Modena, Italy at the turn of the 18th century. (Ten US gal/ton is approximately 3.4 tons of oil per 100 tons of shale.) Sulfur and nitrogen, along with the arsenic and iron that may be present, also destroy the catalysts used in refining.

Although shale-oil plays with oil stored in open-fractured shale have been pursued for more than 100 yr, organic-rich and low-permeability shales and hybrid shale-oil systems are now being pursued based on knowledge and technologies gained from production of shale-gas resource systems and likely hold the largest untapped oil resource potential. Definition of oil shale. What does shale oil mean? "[23][24], The amount of oil that can be recovered during retorting varies with the oil shale and the technology used. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Definition - What does Oil Shale mean?

Deep spending cuts that came with the collapse in fuel demand and oil prices due to the COVID-19 pandemic have ended an era that put the U.S. atop the ranks of the world's biggest producers. U.S. oil and gas shares and drilling activity are edging higher, but a disastrous year for the energy industry means the go-go days of the shale boom may be gone for good. Mineral particles and metals are often present as well. Shale definition is - a fissile rock that is formed by the consolidation of clay, mud, or silt, has a finely stratified or laminated structure, and is composed of minerals essentially unaltered since deposition. [4] In the 10th century, the Arabic physician Masawaih al-Mardini (Mesue the Younger) first described a method of extracting oil from "some kind of bituminous shale". humic shale - shale that is rich in humic acids. Shale definition: Shale is smooth soft rock that breaks easily into thin layers. Another 20% will teeter on the edge. This website contains assessments and geologic reports , as well as spatial and tabular datasets, fischer assays and well logs from USGS oil shale research studies. Fracturing shallow, hard rock wells to extract oil dates back to the 1860s. [37][38] Olefins form insoluble sediments and cause instability. half shark, half whale. Shale oil is a substitute for conventional crude oil; however, extracting shale oil from oil shale is more costly than the production of conventional crude oil both financially and in terms of its environmental impact. shale gas definition: 1. natural gas that is found in shale (= a type of soft, grey rock): 2. natural gas that is found…. Oil shale definition: a fine-grained shale containing oil , which can be extracted by heating | Meaning, pronunciation, translations and examples It consists mainly of hydrocarbons of the paraffin, olefine, and crotonylen series, and yields as the principal commercial products illuminating- … "[10] Modern shale oil extraction industries were established in France during the 1830s and in Scotland during the 1840s. Definition of shale oil. : a crude dark oil obtained from oil shale by heating. The refined products can be used for the same purposes as those derived from crude oil. Eagle Ford Shale. [11] The oil was used as fuel, as a lubricant and lamp oil; the Industrial Revolution had created additional demand for lighting. WordSense.eu Dictionary: shale oil - meaning, definition, anagrams. Oil shale is a type of sedimentary rock formation that is used to produce oil and gas. Shale oil is one of the unconventional oils; it is produced from oil shale rock fragments by hydrogenation, pyrolysis, or thermal dissolution. The term "shale oil" is also used for crude oil produced from shales of other very low permeability formations. Numerous oil rigs set up in Texas in 2016. In The History of On-Shore Hydrocarbon Use in the UK", "Studies of the Scottish oil shale industry. Up to 1/3 of the rock can be solid kerogen. [36], Shale oil's concentration of high-boiling point compounds is suited for the production of middle distillates such as kerosene, jet fuel and diesel fuel. Shale oil is the oil that is produced in an informal way from the oil shale rock formations by using different techniques. [40] Upgrading shale oil into transport fuels requires adjusting hydrogen–carbon ratios by adding hydrogen (hydrocracking) or removing carbon (coking). A 1984 study estimated the EROEI of the various known oil-shale deposits as varying between 0.7–13.3. Many people get confused by the terms Oil Shale and Shale Oil; however, both are completely different. [15] About one sixth of the oil shales in the Green River Formation have a relatively high yield of 25 to 100 US gallons (95 to 379 l; 21 to 83 imp gal) of shale oil per ton of oil shale; about one third yield from 10 to 25 US gallons (38 to 95 l; 8.3 to 20.8 imp gal) per ton. Shale oil is an unconventional oil that is extracted from shale rock. Shale oil is also different than oil shale, which is a type of sedimentary rock that has low permeability and bituminous-like (consisting mainly of hydrocarbons) solids that can be liquefied during the extraction process. [31][41][42] Additional cracking can create the lighter hydrocarbons used in gasoline. Oil Shale. The temperature at which the kerogen decomposes into usable hydrocarbons varies with the time-scale of the process; in the above-ground retorting process decomposition begins at 300 °C (570 °F), but proceeds more rapidly and completely at higher temperatures. Shale oil is an unconventional oil produced from oil shale rock fragments by pyrolysis, hydrogenation, or thermal dissolution.
