Pros and cons of tar sand and oil shale
Oil shale and tar sands occur in dozens of countries around the world. With in- place pros and cons to each, but at the moment there is insuffi- cient diluent to 31 Aug 2009 Pollution is one argument against the oil sands development. Global News takes a look at the pros and cons involved in developing the oil sands. forest, but such a move could also fuel further development of the tar sands. What is tar sand , or oil sand , and how is it extracted and converted to heavy oil? and disadvantages of using heavy oils produced from tar sand and shale oil high pressure, the tar cannot be pro duced from Two basic approaches have been con crude oil. One involves mining the sand and somehow washing the tar from it. OIL SHALE deposits of the U.S. are concentrated in high plateaus.
Both involve 'immature' hydrocarbons (kerogen or semisolid tar) contained in sedimentary rocks such as shale, sandstone, or limestone Pros of Oil Shales, Tar Sands Large deposits occur in North America (oil shale in western U.S.; tar sands in Alberta, Canada)
Tar sands are mined and processed to generate oil similar to oil pumped from conventional oil wells, but extracting oil from tar sands is more complex than conventional oil recovery. Oil sands recovery processes include extraction and separation systems to separate the bitumen from the clay, sand, and water that make up the tar sands. Cons: - The cost of processing, refining and upgrading the bitumen from the tar sands is extremely expensive and harmful to the environment in almost every way - Even though we have large amounts of the oil, majority of it gets sent to the United States, even when the prices of gasoline are continually rising in Canada - If the price of crude oil were to ever drop a great deal, Canada’s economy as a whole will plummet. Shale Gas, Pros & Cons. Shale gas requires an aggressive method of collection since it is buried deep in the earth under many layers of shale. The most popular method of collecting shale gas is hydraulic fracking, a relatively new technology, which has become quite controversial. Tar sands and shale can provide oil as well. Because it is a fossil fuel, however, oil is a finite resource. There is the possibility that we may run out of it one day or be forced to ration how we use it. Global News takes a look at the pros and cons involved in developing the oil sands. A scientific panel said Tuesday that weaknesses in measuring pollution from the Alberta oil sands must be corrected. Heavy Oils from oil shale and Oil sand. Pros: Large potential supplies; Easily transported within and between countries; efficient distribution system in place. Heavy Oils from oil shale and Oil sand. Cons: Low Energy Yield; Releases CO2 and other pollutants when burned; Severe land disruption and high water use. This makes tar sands a game changer, in a playing field where oil companies have dominated for a long time.-A large part of the Alberta oil sands mining operations involves clearing trees, brush, topsoil, sand and clay that sit on top of the oil sands deposit. But steps are being taken to mitigate the effect this has on local animal species.

Shale oil is a high-quality crude oil that lies between layers of shale rock, impermeable mudstone, or siltstone. Oil companies produce shale oil by fracturing the layers of rock that contain the layers of oil. Don't confuse shale oil with oil shale. Pros & Cons of Oil Sands Summarized by Walter Sorochan, Posted 2009 Updated February 10, 2011. There is controversy about the development of oil sand regions in the Canadian province of Alberta. Tar sands and shale can provide oil as well. Because it is a fossil fuel, however, oil is a finite resource. There is the possibility that we may run out of it one day or be forced to ration how we use it. Tar sands, for example, are considered a potential energy source that is economically feasible at its current prices, but with major trade offs. The oil sands in Alberta, for instance, produce toxic sludge that can have catastrophic environmental impact, as it can contaminate Alberta’s groundwater.
4 Mar 2013 Oil shale is a type of rock that can be burned for energy or fuel. Calcite helps form the shells and hard exteriors of oysters, sea stars, and sand dollars. Another environmental disadvantage to extracting shale oil is the enormous must weigh the cost of extraction with the benefits of an oil resource.
Oil sands, tar sands, crude bitumen, or more technically bituminous sands, are a type of These source rocks were similar to the American so-called oil shales, except the latter have never been buried 10% versus 5–6% with sand filters in place) and the disadvantage that disposing of the produced sand is a problem. 11 Mar 2020 The Canadian government has invested heavily in the use of Carbon Capture and Storage for the tar sands recovery process, but this The Pros of Tar Sands. 1. It provides a localized economic benefit. Tar sands that were found in Alberta have helped Canada become the #1 foreign supplier of oil 12 Apr 2013 General Reference (not clearly pro or con) the following on their 2012 Oil Shale & Tar Sands Programmatic EIS website, Tar sands can be mined and processed to extract the oil-rich bitumen, which is then refined into oil.
Shale Oil and the Pros and Cons of Fracking. Shale oil is a high-quality crude oil that lies between layers of shale rock, impermeable mudstone, or siltstone. Oil companies produce shale oil by fracturing the layers of rock that contain the layers of oil. Don't confuse shale oil with oil shale.
mostly of Cambrian age, and lenticular beds of barren siltstones and shales. [I]. Athabasca tar-sand oil is also high - in the range of 4 4 % - and contains tar sands. The pros and cons of Arctic and eastern Canada offshore areas have been. 20 Mar 2018 Some of the unconventional resources include tar sand, shale oil, they cannot be exploited with the available technologies used in exploiting the “con- ( benefits and implications) of exploiting Nigerian Tar sand using hot. 4 Mar 2013 Oil shale is a type of rock that can be burned for energy or fuel. Calcite helps form the shells and hard exteriors of oysters, sea stars, and sand dollars. Another environmental disadvantage to extracting shale oil is the enormous must weigh the cost of extraction with the benefits of an oil resource. 27 May 2015 Pros and cons of fracking: 5 key issues.
