However, high boiling point compounds in shale oil can be used to produce middle distillates such as kerosene, diesel, jet fuel, etc. US shale was expected to grow by 650,000 barrels a day this year before the coronavirus outbreak wiped out forecasts for global oil demand, triggering one of the steepest oil … Compare the Difference Between Similar Terms. Oil shale is a type of sedimentary rock formation that is used to produce oil and gas.   Home » Science » Chemistry » Difference Between Crude Oil and Shale Oil. As a result, the United States became the world’s largest crude-oil producer, according to the Energy Information Administration. Petroleum is the most abundantly used source of energy, and it generally exists in the liquid state. CRC press: 2014. Unlike crude oil, this is not frequently used as a raw material for chemical products. Shale oil is mainly used as heating oil, marine fuel or chemical for railroad wood preservative, etc. These processes produce an unconventional oil which can be readily used as a fuel or can also be improved to achieve feedstock specifications by doing additional purification methods. It takes such a long time to produce crude oil by bacterial transformation of organic matter such as carbohydrates and proteins from plant and animal origin. So it should be refined to meet the required specifications of its end use applications. That means … However, the typical oil has a high proportion of volatile compounds and low sulfur content. Shale oil and crude oil are two types of energy sources.   Shale oil comprises more than a third of the onshore production of crude oil in the lower 48 states. The presence of low boiling point constituents makes the shale oil extremely explosive and highly flammable. Transportation fuels produced by shale oil is of low quality compared to higher grade conventional fuels. Petroleum ether (C5, C6), straight rum gasoline, Table 1. Hydraulic Fracturing: Do or Die for U.S. Oil. Their mineral composition varies with its origin, and generally, it contains clay minerals, dolomite, calcite, and carbonates, etc. They are naturally present in liquid form and can be obtained by natural gas by condensation or extraction. The shale oil is also known as “light tight oil” and is produced from oil shale rock fragments by the process of pyrolysis (Thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen (or any halogens). All rights reserved. Oil Shale vs. Shale Oil: What Investors Need to Know In a confusion of terms, oil shale and shale oil take on a whole new meaning for investors, with billions of barrels of oil at stake. Speight, J. G., Handbook of petroleum product analysis. In contrast to crude oil, Shale oil is a non-petroleum fuel, which naturally exist in a solid state as an oil shale rock or kerogen. ... shale oil production growth was already projected to slow sharply due to lower oil … The product obtained from these processes can be readily used as fuel or can be refined to remove impurities and to enhance its qualities. Shale Oil: The shale oil extraction is an unconventional oil production process. The commercially important oil shale reservoirs are located in Wyoming, Utah and Colorado states of northwestern United States. Speight, J. G., The chemistry and technology of petroleum. Although some of the largest oil companies are still trying to make the numbers work, the reality here is that the production process requires too much time, money, and water right now. The kerogen deposits on shale oil rocks gently convert into crude oil by natural processes. How much more attractive will developing the Green River oil shale be when a barrel of crude oil costs $200? The kerogen deposits on shale oil rocks gently convert into crude oil by … It involves the conversion of kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. There will be increased truck traffic, more rigs traveling to sites, and even more methane in the local atmosphere as the tight oil … The chemical composition and physical properties of crude oil such as color, odor, volatility, specific gravity, viscosity, etc. Most of the transportation fuels such as gasoline, diesel, and aviation fuels are fractional distillates of crude oil. Since 2014, U.S. shale oil has created a boom in domestic crude oil production. 1. The organic materials (kerogen) in sediments cannot be converted to shale oil without supplying high-temperature treatments such as pyrolysis, hydrogenation or thermal dissolution. That means shale producers must always be spending a great deal of money to drill new wells to replace the lost production. These oil shales are argillaceous, laminated sediments, generally with high organic content that can be thermally decomposed to produce oil which is known as shale oil. The dirtiest oil in the index, Suncor Energy’s Synthetic H blend, requires extensive amounts of energy to extract out of the Canadian oil sands. Shale oil has not to exposed to sufficient pressure and temperature to convert trapped hydrocarbons into crude oil. The key difference between shale oil and crude oil  is in its composition; Shale oil contains relatively large quantities of sulfur, nitrogen, and oxygen than that of crude oil. Shale oil has not to exposed to sufficient pressure and temperature to convert trapped hydrocarbons into crude oil. It is generally less economical than conventional crude oil. After mining the oil shale, it is treated providing other processing facilities. The following Table shows the fraction of typical distillation of crude oil. The tar-like crude must then be processed before it’s suitable for refining, another energy-intensive process. It is true that net crude oil imports have fallen by nearly 60% since President Obama took office. The extraction process is usually performed above the ground. Moreover, it can be used as raw material for many chemical products such as plastics, pharmaceuticals, fertilizers, pesticides, solvents, etc. 2008. vary with pressure, volume and temperature of the origin of the crude petroleum. OPEC vs. Shale: the Battle for Oil Price Supremacy Oil prices are in a tug of war between the huge increase in U.S. shale production and the cartel’s attempts to slash its own output Difference Between Hexane and Cyclohexane, Difference Between Ductility and Malleability, What is the Difference Between Aioli and Mayonnaise, What is the Difference Between Massage Oil and Body Oil, What is the Difference Between Chia and Basil Seeds, What is the Difference Between Soy and Paraffin Wax, What is the Difference Between Red and White Miso, What is the Difference Between Bamboo and Cotton Sheets. The oil in shale is typically found in smaller batches. According to the statistical evaluations, typical shale oil contains more nitrogenous compounds, more oxygenated compounds, and low sulfur content compared to conventional crude oil. Chemical composition of typical crude oil and shale oil by weight. Messel oil shale sideritic laminae By Gretarsson (Own work) [GFDL or CC BY-SA 3.0], via Wikimedia Commons, 2. The key difference between shale oil and crude oil is in its composition; Shale oil contains relatively large quantities of … If sulfur content is higher than 0.5% (w/w), they are called sour crude, and if it’s less than 0.5% (w/w), they are called sweet crude. Therefore, shale oil is also called as a synthetic crude oil. But, the cost of production of shale oil is comparatively low. This temperature and pressure vary with the depth of the reservoir. This has a low economic value compared to refined oil. John Wiley & Sons: 2015. And the truth is that nearly all of this was supplied through conventional drilling. It has high fluidity, and it’s pourable at a high-temperature range. Shale oil and crude oil are two types of energy sources. Shale oil, in fossil fuel production, either a synthetic crude oil that is extracted from oil shale by means of pyrolysis or a naturally occurring crude oil that is extracted from underground shale deposits by means of fracking (hydraulic fracturing). ], via Wikimedia Commons, 2 petroleum crude oil naturally occurs as a free lunch in the first to.
