WebAsphalt: In the asphalt, aggregates, bitumen, and additives are gathered together with the purpose of covering the surface of the road.The aggregates made up about 95% of the mass of asphalt and the rest 5% is bitumen which plays a role of a binder. Individual sheets of mod bit are typically between 120 mils (3.05 mm or 0.12 inches) and 180 mils (4.6 mm or 0.18 inches) thick. In 1787, fur trader and explorer Alexander MacKenzie on his way to the Arctic Ocean saw the Athabasca oil sands, and commented, "At about 24 miles from the fork (of the Athabasca and Clearwater Rivers) are some bituminous fountains into which a pole of 20 feet long may be inserted without the least resistance. Shell plc is a British multinational oil and gas company headquartered in London, England. In 2015, the Canadian Energy Research Institute (CERI) re-estimated the average plant gate costs (again including 10% profit margin) of SAGD to be $58.65/bbl, and 70.18/bbl for mining without upgrading. Presently, roads are mostly constructed using Bitumen. The International Energy Agency (IEA) lists the economically recoverable reserves, at 2007 prices and modern unconventional oil production technology, to be 178 billion barrels (28.310^9m3), or about 10% of these deposits. In the Athabasca sands there are very large amounts of bitumen covered by little overburden, making surface mining the most efficient method of extracting it. As you know it by now, bitumen is obtained from the distillation of crude oil. While much of Canada's oil sands are being produced using open-pit mining, approximately 90% of Canadian oil sands and all of Venezuela's oil sands are too far below the surface to use surface mining. [53] The Government of Alberta reported in 2013 that tailings ponds in the Alberta oil sands covered an area of about 77 square kilometres (30sqmi). The hydrodynamic conditions of oil transport were similar, source rocks buried deep by the rise of the mountains of the Sierra Orientale produced light oil that moved up-dip toward the south until it was gradually immobilized by the viscosity increase caused by biodgradation near the surface. As of late 2015, development of new oil sand projects were deterred by the price of WTI below US$50, which is barely enough to support production from existing operations. Examples include Japan Canada Oil Sands Ltd's (JACOS) project, Suncor's Firebag project, Nexen's Long Lake project, Suncor's (formerly Petro-Canada's) MacKay River project, Husky Energy's Tucker Lake and Sunrise projects, Shell Canada's Peace River project, Cenovus Energy's Foster Creek[58] and Christina Lake[59] developments, ConocoPhillips' Surmont project, Devon Canada's Jackfish project, and Derek Oil & Gas's LAK Ranch project. This study found that tailings ponds were an indirect pathway transporting uncontrolled releases of evaporative emissions of three representative polycyclic aromatic hydrocarbon (PAH)s (phenanthrene, pyrene, and benzo(a)pyrene) and that these emissions had been previously unreported. [129] In 2007, the Alberta government issued an environmental protection order to Suncor in response to numerous occasions when ground level concentration for H2S) exceeded standards. Yet they're completely different materials. per square foot. The result was that foreign companies left Venezuela, as did most of its elite heavy oil technical experts. The greater the temperature difference, the faster the heat flows to the colder area. The main differences is that the oil in the sands in Venezuela is less viscous than in Canada, allowing some of it to be produced by conventional drilling techniques, but none of it approaches the surface as in Canada, meaning none of it can be produced using surface mining. Although smaller than the Athabasca oil sands, the Cold Lake oil sands are important because some of the oil is fluid enough to be extracted by conventional methods. [105] During the 2020 RussiaSaudi Arabia oil price war, the price of Canadian heavy crude dipped below $5 per barrel.[106]. [48], Except for a fraction of the extra-heavy oil or bitumen which can be extracted by conventional oil well technology, oil sands must be produced by strip mining or the oil made to flow into wells using sophisticated in-situ techniques. Canada also has huge undeveloped shale gas deposits in addition to those of the US, so natural gas for future oil sands production does not seem to be a serious problem. Coal tar and mineral pitch materials though of similar basic [19] The word "tar" to describe these natural bitumen deposits is really a misnomer, since, chemically speaking, tar is a human-made substance produced by the destructive distillation of organic material, usually coal. The original Tar & Roses team of Don Lewis and Narelle King began their winemaking journey in Priorat, Spain, immersing themselves within the classic Mediterranean wine regions and varietals. Understand the difference between Asphalt and Varnish. [128] Prior to 2012, air monitoring showed significant increases in exceedances of hydrogen sulfide (H2S) both in the Fort McMurray area and near the oil sands upgraders. Proven reserves of bitumen contain approximately 100 billion barrels,[4] and total natural bitumen reserves are estimated at 249.67Gbbl (39.69410^9m3) worldwide, of which 176.8Gbbl (28.1110^9m3), or 70.8%, are in Alberta, Canada.[1]. Apart from the megagiant[38] oil sands deposits in Canada and Venezuela, numerous other countries hold smaller oil sands deposits. Despite that, one look at the two driveways, and you can see a big difference. Syncrude's second mine began operation in 1978 and is the biggest mine of any type in the world. However, governments have become concerned about the large volume and composition of oil spread on roads. To flow through oil pipelines, it must either be upgraded to lighter synthetic crude oil (SCO), blended with diluents to form dilbit, or heated to reduce its viscosity. [162][163][164], In November 2014, Fatih Birol, the chief economist of the International Energy Agency, described additional greenhouse gas emissions from Canada's oil sands as "extremely low". For the benefit of oil marketers, in 2004 Western Canadian producers created a new benchmark crude oil called Western Canadian Select, (WCS), a bitumen-derived heavy crude oil blend that is similar in its transportation and refining characteristics to California, Mexico Maya, or Venezuela heavy crude oils. [72] Since a barrel of oil equivalent is about 6.117 gigajoules (1,699kWh), its EROEI is 56. Of this, oil sands bitumen accounts for 90 per cent. The US resumed export of crude oil in 2016; as of early 2019, the US produced as much oil as it consumed, with shale oil displacing Canadian imports. The excess oil production from the oil sands could be exported. Following that, the government re-nationalized the Venezuelan oil industry and increased taxes on it. [39] In addition to being much smaller than the Canadian oil sands deposits, the US oil sands are hydrocarbon-wet, whereas the Canadian oil sands are water-wet. Low-cost production by OPEC continued at maximum capacity, efficiency of production from U.S. shales continued to improve, and Russian exports were mandated even below cost of production, as their only source of hard currency. Then in late 2014 the dramatic rise in U.S. production from shale formations, combined with a global economic malaise that reduced demand, caused the price of WTI to drop below $50, where it remained as of late 2015. Between them, they cover over 140,000 square kilometres (54,000sqmi)an area larger than Englandand contain approximately 1.75Tbbl (28010^9m3) of crude bitumen in them. Catalyst materials and pore size distributions are key parameters that need to be optimized to deal with this challenge and varies from place to place, depending on the kind of feedstock present. According to the Oil Climate Index, carbon emissions from oil-sand crude are 31% higher than from conventional oil. Sealant is a substance used to block the passage of fluids through openings in materials, a type of mechanical seal.In building construction sealant is sometimes synonymous with caulking and also serve the purposes of blocking dust, sound and heat transmission. [17], The name tar sands was applied to bituminous sands in the late 19th and early 20th century. [118] The environmental impact caused by oil sand extraction is frequently criticized by environmental groups such as Greenpeace, Climate Reality Project, Pembina Institute, 350.org, MoveOn.org, League of Conservation Voters, Patagonia, Sierra Club, and Energy Action Coalition. [45], By 2013 there were nine oil sands mining projects in the Athabasca oil sands deposit: Suncor Energy Inc. (Suncor), Syncrude Canada Limited (Syncrude)'s Mildred Lake and Aurora North, Shell Canada Limited (Shell)'s Muskeg River and Jackpine, Canadian Natural Resources Limited (CNRL)'s Horizon, Imperial Oil Resources Ventures Limited (Imperial), Kearl Oil Sands Project (KOSP), Total E&P Canada Ltd. Joslyn North Mine and Fort Hills Energy Corporation (FHEC). RAMP studies show that deformity rates are normal compared to historical data and the deformity rates in rivers upstream of the oil sands. [27], Together, these oil sand deposits lie under 141,000 square kilometres (54,000sqmi) of boreal forest and muskeg (peat bogs) and contain about 1.7 trillion barrels (27010^9m3) of bitumen in-place, comparable in magnitude to the world's total proven reserves of conventional petroleum. The area along the Tigris and Euphrates rivers was littered with hundreds of pure bitumen seepages. Instead of steam, hydrocarbon solvents are injected into an upper well to dilute bitumen and enables the diluted bitumen to flow into a lower well. If the entire oil-in-place of 1.8 trillion barrels were to be burnt, the predicted global mean temperature increase is 0.24 to 0.50C. Bitumen: A substance produced through the distillation of crude oil and known for its waterproofing and adhesive properties. The Athabasca deposit is the largest known reservoir of crude bitumen in the world and the largest of three major oil sands deposits in Alberta, along with the nearby Peace River and Cold Lake deposits (the latter stretching into Saskatchewan). The natural gas pipelines to the east and south are being converted to carry increasing oil sands production to these destinations instead of gas. which would make it the largest petroleum reserve in the world. Almost all of the remaining oil is found in the far north of Alberta, in Middle Cretaceous (115 million-year old) sand-silt-shale deposits overlain by thick shales, although large amounts of heavy oil lighter than bitumen are found in the Heavy Oil Belt along the Alberta-Saskatchewan border, extending into Saskatchewan and approaching the Montana border. At the much lower prices of 2015, the reserves are much smaller. [161] In July 2008, the Alberta government announced a C$2billion fund to support sequestration projects in Alberta power plants and oil sands extraction and upgrading facilities. Tar paper is a heavy-duty paper used in construction.Tar paper is made by impregnating paper or fiberglass mat with tar, producing a waterproof material useful for roof construction. The largest Canadian oil sands deposit, the Athabasca oil sands is in the McMurray Formation, centered on the city of Fort McMurray, Alberta. Canadian oil sands are much colder and more biodegraded, so bitumen recovery rates are usually only about 56%. The cyclic steam stimulation (CSS) "huff-and-puff" method is now widely used in heavy oil production worldwide due to its quick early production rates; however recovery factors are relatively low (1040% of oil in place) compared to SAGD (6070% of OIP). Significant bitumen deposits are reported in Canada,[1][2] Kazakhstan, Russia, and Venezuela. It is a petroleum product. Following that cycle, air is injected into the vertical wells, igniting the upper bitumen and mobilizing (through heating) the lower bitumen to flow into the production well. Canada has vast energy resources of all types and its oil and natural gas resource base would be large enough to meet Canadian needs for generations if demand was sustained. Architectural shingles are practically twice as thick as three-tab shingles. Note that, although adjacent to Alberta, Saskatchewan has no massive deposits of bitumen, only large reservoirs of heavy oil >10API.[6][26]. [98], A shortage of skilled workers in the Canadian oil sands developed during periods of rapid development of new projects. Further research disclosed that pumping out sand opened "wormholes" in the sand formation which allowed more oil to reach the wellbore. A tack coat is applied after the prime coat, to form an adhesive bond between the tack coat and the next layer of coating. There is sufficient heavy oil refinery capacity in China and India to refine the additional Canadian volume, possibly with some modifications to the refineries. [76][77]:9[78][79] No estimate of how much of the oil is economically recoverable was made.[37]. [176], In a report released in 2014, Alberta's Chief Medical Officer of Health, Dr. James Talbot, stated that "There isnt strong evidence for an association between any of these cancers and environmental exposure [to oil sands]." * Reason For Confusion Between Tar and Bitumen: Both have black color and both have very good Waterproofing and adhesion property. [100] Thus, all types of oil sands projects except new mining projects with integrated upgraders were expected to be consistently profitable from 2011 onward, provided that global oil prices remained favourable. [40] This requires somewhat different extraction techniques for the Utah oil sands from those used for the Alberta oil sands. Significant bitumen deposits are reported in Canada, Kazakhstan, Russia, As the demand for automobile fuel increased, however, so did the availability of bitumen and, hence, of good asphalt designed to the standards of de Smedt and Richardson. The main market for Canadian bitumen as well as Venezuelan extra-heavy oil was assumed to be the US. [74] Thus, it will produce syncrude without consuming natural gas, but the capital cost is very high. It is used in road making While its major component is bitumen, it also contains a combination of sweet synthetic and condensate diluents, and 25 existing streams of both conventional and unconventional oil[80] making it a syndilbit both a dilbit and a synbit. The largest, the Athabasca oil sands, are located to the east, the second largest the, Cold Lake oil sands deposit is south of Athabaska and the Wabasco oil sands are south of Athabaska and usually linked to it. In the absence of other constraints on further development, the oil and gas industry would need to fill tens of thousands of job openings in the next few years as a result of industry activity levels as well as age-related attrition. The estimated worldwide deposits of oil are more than 2 trillion barrels (320billion cubic metres);[3] the estimates include deposits that have not been discovered. [139], Between 2 and 4.5 volume units of water are used to produce each volume unit of synthetic crude oil in an ex-situ mining operation. Asphalt is still used today in a variety of applications while tarmac is only used for specialized projects. Heavy crude feedstock needs pre-processing before it is fit for conventional refineries, although heavy oil and bitumen refineries can do the pre-processing themselves. The collision compressed the Alberta plains and raised the Rockies above the plains, forming mountain ranges.

WebTar And Bitumen * Tar: No longer used for road construction because of its *Carcinogenic Effect and high temperature susceptibility. WebAnd a Tar is a dark, thick, flammable liquid distilled from wood or coal, consisting of a mixture of hydrocarbons, resins, alcohols, and other compounds. The oil sands themselves are typically 40 to 60 metres (130 to 200ft) thick deposits of crude bitumen embedded in unconsolidated sandstone, sitting on top of flat limestone rock. [62], Advocates of this method of extraction state that it uses less freshwater, produces 50% less greenhouse gases, and has a smaller footprint than other production techniques. It is preferable to lay AC layers over a bituminous base or binder route. Although oil sands exports to Europe are minimal, the issue has caused friction between the EU and Canada. "[8], There is conflicting research on the effects of the oil sands development on aquatic life. [25] They are too deep to surface mine. [49], Conventional crude oil is normally extracted from the ground by drilling oil wells into a petroleum reservoir, allowing oil to flow into them under natural reservoir pressures, although artificial lift and techniques such as horizontal drilling, water flooding and gas injection are often required to maintain production. Dr. Birol acknowledged that there is tremendous difference of opinion on the course of action regarding climate change, but added, "I hope all these reactions are based on scientific facts and sound analysis. On the other hand, tar is obtained from the combustion of coal in specific conditions of temperature and without oxygen. The 1973 and 1979 oil price increases, and development of improved extraction technology enabled profitable extraction and processing of the oil sands. Other deposits are located in the Timan-Pechora and Volga-Urals basins (in and around Tatarstan), which is an important but very mature province in terms of conventional oil, holds large amounts of oil sands in a shallow permian formation. [145] In addition, according to the Water Management Framework for the Lower Athabasca River, during periods of low river flow water consumption from the Athabasca River is limited to 1.3% of annual average flow. [33] In 2007 the World Energy Council estimated that these oil sands areas contained at least two-thirds of the world's discovered bitumen in place at the time,[34] with an original oil-in-place (OOIP) reserve of 260,000,000,000 cubic metres (9.21012cuft) (1.6 trn barrels), an amount comparable to the total world reserves of conventional oil. Bitumen Bitumen is actually the Liquid Binder that holds Asphalt together. The bitumen image was the drawings negative: the back is colored in the dark bitumen brown and the lines are represented by the raw metal. [104] [122] According to the California-based Jacobs Consultancy, the European Union used inaccurate and incomplete data in assigning a high greenhouse gas rating to gasoline derived from Alberta's oilsands. In an effort to identify the sources of the noxious odours in the Fort McKay community, a Fort McKay Air Quality Index was established, extending the provincial Air Quality Health Index to include possible contributors to the problem: SO2, TRS, and THC. The light oil migrated up-dip through hydro-dynamic transport from the Rockies in the southwest toward the Canadian Shield in the northeast following a complex pre-Cretaceous unconformity that exists in the formations under Alberta. The tack coat prevents slippage and may sometimes function as a more long-term sealer to protect the substrate from moisture and bacteria. The volume of both upgraded and non-upgraded bitumen is increasing yearly. Typically, blended bitumen contains about 30% natural gas condensate or other diluents and 70% bitumen. Catalytic purification and hydrocracking are together known as hydroprocessing. The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of bitumen or extremely heavy crude oil, located in northeastern Alberta, Canada roughly centred on the boomtown of Fort McMurray.These oil sands, hosted primarily in the McMurray Formation, consist of a mixture of crude bitumen (a semi-solid rock-like form of crude oil), silica sand, clay It has the advantage of much better energy efficiency over steam injection, and it does some partial upgrading of bitumen to oil right in the formation. The original oil sands upgraders were designed to produce a high-quality synthetic crude oil (SCO) with lower density and lower sulfur content. Most of the Canadian oil refining industry is foreign-owned. The National Energy Board (NEB) reported in 2013, that if oil prices are above US$100, Canada would have more than enough energy to meet its growing needs. David W. Schindler, a limnologist from the University of Alberta, co-authored a study on Alberta's oil sands' contribution of aromatic polycyclic compounds, some of which are known carcinogens, to the Athabasca River and its tributaries. Canadian refineries, outside of Alberta and Saskatchewan, were originally built for light and medium crude oil. WebThere's often a lot of confusion in the public's mind between bitumen and tar. Once it is back in the US, refineries separate the diluent and re-export it to Canada, which again bypasses US crude oil export laws since it is now a refinery product. Tar paper is distinguished from roofing felt, which is impregnated with asphalt instead of tar, but these two products are used the same way, and their names are sometimes used informally as synonyms. [174] However, John O'Connor, the doctor who initially reported the higher cancer rates and linked them to the oil sands development, was subsequently investigated by the Alberta College of Physicians and Surgeons. The demand from US refineries is increasingly for non-upgraded bitumen rather than SCO. [142] The average flow just downstream of Fort McMurray is 633m3/s (22,400cuft/s) with its highest daily average measuring 1,200m3/s (42,000cuft/s). It's a thick liquid that holds high carbon content. This mountain building process buried the sedimentary rock layers which underlie most of Alberta to a great depth, creating high subsurface temperatures, and producing a giant pressure cooker effect that converted the kerogen in the deeply buried organic-rich shales to light oil and natural gas. [6][26], The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of bitumen or extremely heavy crude oil, located in northeastern Alberta, Canada roughly centred on the boomtown of Fort McMurray. There are increasing political obstacles to building any new pipelines to deliver oil in Canada and the US. Since the larger and more sophisticated refineries preferred to buy raw bitumen and heavy oil rather than synthetic crude oil, new oil sands projects avoided the costs of building new upgraders. [14][a] The International Energy Agency made similar comparisons.[15]. By 2016, with the economy of Venezuela in a tailspin and the country experiencing widespread shortages of food, rolling power blackouts, rioting, and anti-government protests, it was unclear how much new oil sands production would occur in the near future. ", "Sand banks: If unconventional sources of oil, such as oil sands, could be transformed into crude we could still have a 300-year supply left. [134] Approximately 2.5 tons of oil sands are needed to produce one barrel of oil (roughly of a ton). Petro-Canada was also developing a $33 billion Fort Hills Project, in partnership with UTS Energy Corporation and Teck Cominco, which lost momentum after the 2009 merger of Petro-Canada into Suncor.
