the Heavy Oil Belt and Oil Sands deposits in Alberta and. Saskatchewan (Figure 2). The term “unconsolidated” is used to describe the high porosity sandstone 8 Aug 2014 The market pressure for the oil industry in Canada to extract the tar sands is too great, and that crude oil will be burned and the resulting carbon Oil sands are also known as tar sands and bituminous sands. They are Excellent reviews have been published to describe the Alberta oil sands story. ( Clark 6 Oct 2011 Another option is to extract the oil is to heat it underground using steam. Two tons of tar sands and several barrels of water (used in extraction and 5 Oct 2006 Chapter 4 describes the regulatory requirements for several U.S. states Tar sands can be mined and processed to extract the oil-rich bitumen. 23 Feb 2017 It was shown that the second model describes the process kinetics better. M.S., Extraction of bitumen, crude oil and its products from tar sand Oil sands---a complex mix of sand, water and bitumen---look like dirt but smell like diesel fuel. The remaining 10 percent---the “tar” or “oil”--- a mixture of very heavy Describing the machine that digs up the earth, Ben Webster wrote in the For every three barrels of oil that is extracted one is needed for processing.

11 Jul 2008 How to extract oil from Canada's tar sands, destroying habitat, polluting water and increasing carbon emissions as you go.

Oil sands extraction can affect the land when the bitumen is initially mined, water resources by its requirement for large quantities of water during separation of the oil and sand, and the air due to the release of carbon dioxide and other emissions. Oil Sands is a form of heavy oil found in sand and rock primarily in the Athabasca region of Northern Alberta, Canada. Learn more about oil sands and all types of energy at www.studentenergy.org Mining tar sands is one of the most expensive ways to produce crude oil in the world, and with the International Energy Agency assessing 21st-century peak oil demand to be around the corner, it Although this process is friendlier to the local habitat, the burning of natural gas to create steam increases the emission risk by another 10-15% over traditional crude extraction. The pros and cons of tar sands show us that short-term gains happen, but at the expense of long-term problems.

Tar sands are extracted by either surface (open pit) mining or in-situ extraction. Oil sands in Alberta underlie an area of approximately 140,000 km2,

Further, tar sands is a vast resource – 314 billion barrels of technically recoverable bitumen lie below Alberta, Canada alone. The volume of tar sands oil, combined with the energy intensive extraction techniques, means that producing and burning all of this tar sands oil would mean assured climate catastrophe. Challenges Extracting petroleum from tar sands is much more complex than the traditional way of recovering oil. There are two processes that have to be completed to extract the bitumen (the desired oil) from Tar sand, also called bituminous sand, deposit of loose sand or partially consolidated sandstone that is saturated with highly viscous bitumen. Oil recovered from tar sands is commonly referred to as synthetic crude and is a potentially significant form of fossil fuel. A brief treatment of tar sands follows. How to Extract Tar Sands. Mined and processed to extract oil rich bitumen - then refined into oil/gas. Tar Sands Pros. Less than 5% has been produced. Large growing potential. Found in a stable country (rare compared to other fossil fuels). Alberta (10% pop., second largest oil field) → Jobs. Will keep oil prices low. Oil sands extraction can affect the land when the bitumen is initially mined, water resources by its requirement for large quantities of water during separation of the oil and sand, and the air due to the release of carbon dioxide and other emissions. Oil Sands is a form of heavy oil found in sand and rock primarily in the Athabasca region of Northern Alberta, Canada. Learn more about oil sands and all types of energy at www.studentenergy.org

31 Dec 2015 Knight was describing tar sands, a sludgy deposit of sand, clay, to look at the unique risks tar sands oil poses during extraction, refinement,

Oil sands are found worldwide, from Canada to Venezuela and, as you might imagine, in the Middle East. Alberta, Canada, has a booming oil-sand industry -- as many 1 million barrels of synthetic oil are produced there every day, 40 percent of which comes from oil sands [source: Oil Shale & Tar Sands Programmatic EIS Information Center]. As it stands, producing 1.8 million barrels per day of tar sands oil resulted in the emissions of some 47.1 million metric tons of CO2-equivalent in 2011, up nearly 2 percent from the year before Most bitumen is refined for use in gasoline, jet fuel and home heating oil, but petroleum also makes its way into more than 3,000 products you might not expect: ballpoint pens, lipstick, flying discs, even T-shirts.Before it can be used for anything, though, it first needs to be extracted from the sand and then processed. As you can see below oil sands cover an extremely large part of Alberta and that resource is going to be extracted. The question is how? The two most common ways of separate the oil from the sand in the Alberta Oil / Tar Sands is to boil it or put it under pressure while still in the ground. OIl Sands (called Tar sands by its detractors) is made up of natural deposits of sand, clay and bitumen ( this is a heavy black viscous oil) and are mined using strip mining in open pit mines or Further, tar sands is a vast resource – 314 billion barrels of technically recoverable bitumen lie below Alberta, Canada alone. The volume of tar sands oil, combined with the energy intensive extraction techniques, means that producing and burning all of this tar sands oil would mean assured climate catastrophe. Challenges

The Canadian oil sands are a place where tracts of remote forested land are the UN special advisor, Maude Barlow, to describe the landscape of the oil sand the boom in tar sands extraction is destroying their hunting and fishing lands.

Oil sands, tar sands, crude bitumen, or more technically bituminous sands, are a type of In Canada, oil sands production in general, and in-situ extraction, in particular, are The word "tar" to describe these natural bitumen deposits is really a 16 Aug 2012 The oil product extracted from Canada's tar sands isn't like conventional crude. Known as bitumen, it's sticky and so thick, it can't flow down a Tar sands is extreme oil in every way. Its extraction is particularly energy and water-intensive, polluting, and destructive. It is either strip mined or produced by 19 Feb 2016 Currently, 20% of oil sands reserves are accessible via mining techniques. Large shovels scoop the oil sand into trucks which then move it to
