Tar are usually mixture of clayand sand combined with water and varying amounts of a blackthick tar called bitumen.
Oil shale is a rock that contains a waxy mixture of hydrocarbons called kerogen.

∙ 12y ago"Tar sands" is a pejorative (negative) way of referring to heavy petroleum oil mixed with sand which is found in significant amounts in Canada. These deposits are a valuable source of oil for the nect period of time as conventional oil supplies dwindle and alternate energy resources are developed.

What is the method used to extract oil from underground?
This question cannot be properly answered unless the type of oil is specified. One assumption is that the question refers to petroleum.
What is unrefined petroleum called?
There are two possibilities here: crude oil or natural gas. It's possible that oil shale and tar sands could be thought of as unrefined petroleum sources as well.
What are some major disadvantages of the Oil and Tar Sands?
It is somewhat more energy intensive to recover oil from oil sands than it is from conventional oil wells. The "oil" in oil sands is closer to tar and will not flow unless heated or diluted with lighter hydrocarbons. Recovery is usually by either strip mining (where the oil sand is closer to the surface) or by injecting steam, solvents, and/or hot air into the sand (where the sands are deeper). Once the tar/oil is recovered, it must be further pre-processed to turn it into a form that can be handled by conventional oil refineries. This usually requires 3 steps:removal of water, sand, physical waste, and lighter products,catalytic purification to remove sulfur, metals, and nitrogen,hydrogenation - usually through hydro-cracking.These pre-processing steps take large amounts of energy and water, while emitting more carbon dioxide than conventional oil. Most of the oil sands that are currently used as sources of oil use processes that require quite a bit of water for the recovery process. For this reason 'sine' oil sand deposits are even more difficult to process. For example the large oil sand deposits in eastern Utah, which is quite arid, are not being mined.There are also political considerations:President Clinton, by executive order, placed most of the oil sand deposits in eastern Utah off limits for development (some have speculated that it was in retaliation for finishing 3rd in Utah in the Presidential election of 1992 behind Bush and Perot - Bush 43.36, Perot 27.34%, Clinton 24.65%). At the very least, order was driven by eco-politics rather than any issues with technology or economics.One of the largest oil sand deposits in the world is located in Venezuela which nationalized its oil industry in 1975-1976 placing it under the country's state-run oil and natural gas company but allowed for some private development. In 2001, Venezuelan president Hugo Chávez imposed a new Hydrocarbons Law that raised royalties paid by private companies from 1-17% to 20-30%. In 2007, Chávez announced the nationalization of the oil industry and required that all private companies hand over majority ownership to the government of Venezuela. Any company that refused to sign over the majority ownership simply had all their assets seized and turned over to the state-run oil company. This put a damper on oil sand development since the companies with expertise to develop it were no longer willing to risk losing their investment to another seizure by the Chávez government.
The best tar remover is?
Tar is a by product of refining crude oil, petrol will first soften, then given time, disolve the tar.
What is a mixture of clay and sand with bitumen could replace petroleum one day?
The mixture of clay, sand, and bitumen that you mention is normally known as tar sand, and there are large deposits of it in the Canadian province of Alberta, as well as a few other locations. The bitumen can be extracted from the mixture and can then be refined into petroleum products such as gasoline, etc. This is more expensive than using oil from oil wells, however, in a world of very high and ever increasing oil prices, the exploitation of tar sands has become economically viable.
What type of resources does tar sands come from?
Tar sands or oil sands are consist of clay, sand, water, and bitumen. Its bitumen content is extracted and separated to purify it into oil.
Would plants die in tar sands?
Tar sands, also known as oil sands or bituminous sands, consist of clay, sand, water and a form of petroleum known as bitreum. Wheatgrass is one plant which will grow in tar sands.
Where is tar sands produced?
Tar sands, also known as oil sands, are primarily produced in Canada, with the largest reserves located in the province of Alberta. Other countries, such as Venezuela and the United States, also have smaller deposits of tar sands.
Why might we have to start using tar sands instead of normal oil?
There are larger known US supplies of tar sands than petroleum.
What has the author Frederick W Camp written?
Frederick W. Camp has written: 'The Tar sands of Alberta' -- subject(s): Oil sands 'The tar sands of Alberta, Canada'
What are bituminous sands?
Bituminous sands are oil sands , tar sands and more tecnically they're an unconventional petroleum deposit . I hope I hlped you!!
Why are the tar sands a valuable resource?
The Canadian Tar Sands in the Athabaska Valley of Northern Alberta are the world's largest deposit of a heavy oil called bitumen. That's the stuff that is used in asphalt on our major highways and byways. This form of oil is much more expensive to extract from the earth but, as the price of crude oil increases with the diminishing supply of world reserves, the tar sands deposits become increasingly more important as a source of energy. If we could stop using oil altogether, then the tar sands would no longer be important to our lifestyle.
Why do we need tar sands?
Tar sands are needed for their potential to produce oil, which can be refined and used in various applications such as transportation fuels and petrochemical products. However, the extraction and processing of tar sands can have significant environmental impacts, including greenhouse gas emissions and habitat destruction. Alternative energy sources and technologies are being developed to reduce the reliance on tar sands and other fossil fuels.
What is the difference between oil sands and tar sands?
they are both the same. i dont think there is a difference because in wikipedia they have the same page for both.
What are the Athabasca Tar Sands?
The Athabasca Tar Sands, also known as the Athabasca oil sands, are deposits of bitumen in Alberta, Canada. They are a major source of unconventional oil production but are controversial due to environmental concerns surrounding their extraction process, which is energy-intensive and produces high levels of greenhouse gas emissions.
Why don't you use Tar Sands from Canada instead of Middle Eastern Oil?
Canadian tar sands are being used as an energy source, but it is a lot harder, and thus more expensive, to derive oil from the tar sands than to drill it direct from the ground. At the current price of oil, however, it make economic sense to do so. The Canadian Oil Sands are the largest deposit of recoverable oil in the western hemisphere but oil needs to be above $60 a barrel for it to be economically feasible. With oil prices only being above the $60 a barrel for the last 2 years or so, companies are only now moving into develop the sands. Unfortunately, the oil discovery and extraction process for the sands is a slow capital intensive process that will require more time to be fully be online. For a look at who is developing the oil sands, you might look at http://www.canadianoilsand.org. They have a number of articles on the oil sands.
What are some energy sources is nonrenewable?
coal, natural gas, oil, oil shale and tar sands, nuclear power
