It consists mainly of hydrocarbons of the paraffin, olefine, and crotonylen series, and yields as the principal commercial products illuminating- … Oil shale is a rock that contains significant amounts of organic material in the form of kerogen. oil shale - shale from which oil can be obtained by heating. : a rock (such as shale) from which oil can be recovered by distillation. [44][45] Worldwide production of shale oil was estimated at 17,700 barrels per day (2,810 m3/d) in 2008. 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. "[10] Modern shale oil extraction industries were established in France during the 1830s and in Scotland during the 1840s. Natural gas liquids are components of natural gas that are separated from the gas state in the form of liquids. Oil Shale is a sedimentary rock that has naturally occurring mixture of organic chemical compounds called as “Kerogen” which when heated yields crude oil. Shale oil outpaced OPEC in terms of production increase in the past decade—between 2008 and 2018, OPEC added 2.05 mb/d or 17.6 percent of the global supply increase, while the United States supplied 8.53 mb/d of new oil, accounting for 73.2 percent of the increase. A typical shale oil composition includes 0.5–1% of oxygen, 1.5–2% of nitrogen and 0.15–1% of sulfur, and some deposits contain more heteroatoms. Definition of oil shale in the AudioEnglish.org Dictionary. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Oil shale is a rock that contains significant amounts of organic material in the form of kerogen. Information about oil shale in the AudioEnglish.org dictionary, synonyms and antonyms. [40] Upgrading shale oil into transport fuels requires adjusting hydrogen–carbon ratios by adding hydrogen (hydrocracking) or removing carbon (coking). The Marcellus Shale lies under the Appalachian Basin, and spreads across New York, Pennsylvania, Ohio, West Virginia, Maryland, Tennessee, Virginia and Kentucky. Essentially, it is oil trapped in solid form inside various rock formations. Another 20% will teeter on the edge. Meaning of oil shale. 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. The differing properties of the raw oils call for correspondingly various pre-treatments before it can be sent to a conventional oil refinery. Shale definition, a rock of fissile or laminated structure formed by the consolidation of clay or argillaceous material. [36], Particulates in the raw oil clog downstream processes; sulfur and nitrogen create air pollution. The “Shale Revolution” refers to the combination of hydraulic fracturing and horizontal drilling that enabled the United States to significantly increase its production of oil and natural gas, particularly from tight oil formations, which now account for 36% of total U.S. crude oil production. It is used in heating oil, marine fuels, and the production of various chemicals. Difference Between Crude Oil and Shale Oil Occurrence. Up to 1/3 of the rock can be solid kerogen. Shale oil has not to exposed to sufficient pressure and temperature to convert trapped hydrocarbons into crude oil. Unconventional oil is crude oil that has been identified or extracted using novel methods. [11] The oil was used as fuel, as a lubricant and lamp oil; the Industrial Revolution had created additional demand for lighting. 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. The offers that appear in this table are from partnerships from which Investopedia receives compensation. In addition, the process is sometimes criticized for the destructive impact on the environment. In the aftermath of the 2014 oil crash, U.S. shale learned a painful lesson: Not all hedging strategies pay off. ‘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.’ 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. You can also find multiple synonyms or similar words of Shale Oil. [1] The International Energy Agency recommends to use the term "light tight oil" and World Energy Resources 2013 report by the World Energy Council uses the term "tight oil" for crude oil in oil-bearing shales. Shale oil is an unconventional oil produced from oil shale rock fragments by pyrolysis, hydrogenation, or thermal dissolution. shale - a sedimentary rock formed by the deposition of successive layers of clay. A 1984 study estimated the EROEI of the various known oil-shale deposits as varying between 0.7–13.3. Definition of shale oil. Shale oil can, in fact, refer to two types of oil: crude oil that is found within shale formations or oil that is extracted from oil shale. Different methods produce shale oil with different properties. Since 2014, U.S. shale oil has created a boom in domestic crude oil production. 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. [29] Like conventional oil, shale oil is a complex mixture of hydrocarbons, and it is characterized using bulk properties of the oil. [15], Shale oil is extracted by pyrolysis, hydrogenation, or thermal dissolution of oil shale. The shale revolution, which kicked off in 2006 with natural gas and later shifted to crude oil in 2010, propelled the United States into the world’s top producer and a net exporter of oil and gas, weaning the country from its dependence on foreign oil. Exploring Types of Natural Gas Liquids – NGL, U.S. Energy Information Administration (EIA), Shale oil is also different than oil shale. Shale drilling r… Shale oil is a high-quality crude oil that lies between layers of shale rock, impermeable mudstone, or siltstone. [46] In March 2011, the United States Bureau of Land Management called into question proposals in the U.S. for commercial operations, stating that "(t)here are no economically viable ways yet known to extract and process oil shale for commercial purposes". shale oil synonyms, shale oil pronunciation, shale oil translation, English dictionary definition of shale oil. Mineral particles and metals are often present as well. That is, oil shale is the sedimentary rock formation containing a type of organic matter called kerogen that yields oil and gas. [7] The British Crown granted a patent in 1694 to three persons who had "found a way to extract and make great quantities of pitch, tarr and oyle out of a sort of stone. It has been described that raw shale oil has a mild carcinogenic potential which is comparable to some intermediate refinery products, while upgraded shale oil has lower carcinogenic potential as most of the polycyclic aromatics are believed to broken down by hydrogenation. The refined products can be used for the same purposes as those derived from crude oil. 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. The discovery of crude oil in the Middle East during mid-century brought most of these industries to a halt, although Estonia and Northeast China maintained their extraction industries into the early 21st century. Petroleum and natural gas are probably the most familiar hydrocarbons. Oil shale definition: a fine-grained shale containing oil , which can be extracted by heating | Meaning, pronunciation, translations and examples The shale play is one of the largest in terms of geographic area, and the United States Geological Survey (USGS) estimates the formation’s total area to be around 95,000 square miles, ranging in … Many people get confused by the terms Oil Shale and Shale Oil; however, both are completely different. [34] The World Health Organization classifies shale oil as Group 1 carcinogens to humans. The “Shale Revolution” refers to the combination of hydraulic fracturing and horizontal drilling that enabled the United States to significantly increase its production of oil and natural gas, particularly from tight oil formations, which now account for 36% of total U.S. crude oil production. Shale Region. 1,144,000 bpd States. As of 2008, most oil shale industries perform the shale oil extraction process after the rock is mined, crushed and transported to a retorting facility, although several experimental technologies perform the process in place (in-situ). See more. 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. [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. a sedimentary rock containing kerogen from which petroleum-like shale oil can be produced by pyrolysis, hydrogenation, or thermal dissolution.. oil shale … 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. Fracturing shallow, hard rock wells to extract oil dates back to the 1860s. Producing shale oil from shale rock has been traditionally more expensive than conventional crude oil. [31][43], Global technically recoverable oil shale reserves have recently been estimated at about 2.8 to 3.3 trillion barrels (450×10^9 to 520×10^9 m3) of shale oil, with the largest reserves in the United States, which is thought to have 1.5–2.6 trillion barrels (240×10^9–410×10^9 m3). Liquid and gaseous hydrocarbons can be extracted from oil shale, but the rock must be heated and/or treated with solvents. What does shale mean? Oil shale is a type of sedimentary rock formation that is used to produce oil and gas. The page not only provides Urdu meaning of Shale Oil but also gives extensive definition in English language. HOUSTON/NEW YORK (Reuters) - 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 … shale meaning: 1. a type of soft, grey rock, usually formed from clay that has become hard, that breaks easily…. 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. The kerogen deposits on shale oil rocks gently convert into crude oil by natural processes. The richest oil shale ranges from brown to black in colour. In the United States, the largest formations providing shale oil are found in the Permian, Eagle Ford, and Bakken Basins. Depositsof oil shale occur around the … Oil Shale. [37][38] Olefins form insoluble sediments and cause instability. Proper usage and audio pronunciation (plus IPA phonetic transcription) of the word shale oil. The hydrocarbons in oil shale can be used as an alternative to petroleum or natural gas. [6] In 1596, the personal physician of Frederick I, Duke of Württemberg wrote of its healing properties. [5] It was also reported to have been used in Switzerland and Austria in the early 14th century. Through these processes, we take the organic matter within the rock (kerogen) and convert into synthetic oil and gas. [22] Royal Dutch Shell reported an EROEI of three to four in 2006 on its in situ development in the "Mahogany Research Project. The shale industry will be the greatest short and medium-term contributor to the supply destruction that the current oil price environment is inflicting on the global oil industry. Shale oil is also often referred to as synthetic oil and gas or Kerogen. WordSense.eu Dictionary: shale oil - meaning, definition, anagrams. ‘Carbonaceous shale, including oil shale, occurs in beds of clayey to silty mudrock from 0.3 to 3 m thick.’ ‘The term ‘fossil fuels’ is commonly used for the materials tar sands, oil, gas condensates, natural gas, coal, and oil shale and their products.’ Distillate oils from the Kiviter process can also be used as diluents for petroleum-originated heavy oils and as an adhesive-enhancing additive in bituminous materials such as asphalt. Numerous oil rigs set up in Texas in 2016. The U.S. Energy Information Administration (EIA) estimates that more than 300 billion barrels of shale oil might be technically recoverable, making up approximately 10% of total crude oil resources. Scientific Investigations Report 2005–5294", "Using neoteric solvents in oil shale studies", "Energy and the U.S. Economy: A Biophysical Perspective", "Oil Shale Test Project. Meanwhile, the development of fracking techniques has grown rapidly since the 1950s, with the discovery and exploitation of shale formations in the United States throughout the 1970s and 1980s. Zero cash takeovers for Permian producers is a very bad signal for the rest of the industry. [11][14][15] In response to rising petroleum costs at the turn of the 21st century, extraction operations have commenced, been explored, or been renewed in the United States, China, Australia and Jordan. Eagle Ford Shale. About half of the oil shales in the Green River Formation yield less than 10 US gal/ton. [17][18][19][20], A critical measure of the viability of extraction of shale oil lies in the ratio of the energy produced by the oil shale to the energy used in its mining and processing, a ratio known as "Energy Returned on Energy Invested" (EROEI). Video shows what oil shale means. The term "shale oil" is also used for crude oil produced from shales of other very low permeability formations. [7] Shale oil was used to light the streets of Modena, Italy at the turn of the 18th century. Shale oil refers to hydrocarbons that are trapped in formations of shale rock. Oil shale, despite the name, does not actually contain oil, but is a precursor of oil that is converted to crude oil when heated.
