  Tar sands Summary
Tar sands, also referred to as oil sands or bituminous sands, are a combination of clay, sand, water, and bitumen.
Tar sands deposits are found in over 70 countries throughout the world, but three quarters of the world's reserves are in two regions, Venezuela and Alberta, Canada.
Venezuela prefers to call its tar sands "extra-heavy oil", and although distinction is somewhat academic, the extra-heavy crude oil deposit of the Orinoco Belt represent nearly 90% of the known global reserves of extra-heavy oil.

These sands consist of a mixture of crude bitumen, which is a semisolid form of crude oil (aka tar, because the hydrocarbons are more carbon and less hydrogen) that impregnates rocks that are composed primarily of sand and clay.
Hughes, the tar sands "are a complex resource, requiring much time, energy, capital, and other inputs to achieve deliverability." Yes, they are a significant hydrocarbon resource, but the issue is whether or not they are ultimately "deliverable" as a useable end product, at a total price that Canada and its customers can afford.
Tar sand bitumen needs a one-third blend of condensates or a half blend of synthetic light oil to move it through a pipeline.

 Tar sands - Wikipedia, the free encyclopedia
Oil sands are often referred to as non-conventional oil, in order to distinguish the bitumen and synthetic oil extracted from oil sands from the free-flowing hydrocarbon mixtures known as crude oil traditionally produced from oil wells.
The largest of these deposits, the Tar Sand Triangle as it is known, covers an area of 148,000 acres and is located in Wayne and Garfield Counties, between the Dirty Devil and Colorado Rivers.
Originally, the sands were mined with draglines and bucket-wheel excavators and moved to the processing plants by conveyor belts.

There are the vast Athabasca sands that surround this town of 50,000, the Peace River sands to the west and the Cold Lake sands to the southeast, north of the town of Lloydminster.
Tar sands production for many years had been considered cost-effective at $23 a barrel, and with improvements in exploration and extraction technologies, the price tipping point has fallen into the mid-teens, officials here say.
At their height, tar sands royalties were $549 million in 1997, about 16 percent of total $3.4 billion in royalties collected in Alberta, the report says.

 Tar Sands
Tar sands are impregnated sands that yield mixtures of liquid hydrocarbon and require further processing other than mechanical blending before becoming finished petroleum products.
Although tar sands occur in more than 70 countries, the two largest are Canada and Venezuela, with the bulk being found in four different regions of Alberta, Canada: areas of Athabasca, Wabasha, Cold Lake and Peace River.
Developers are required to restore oil sand mining sites to at least the equivalent of their previous biological productivity; which is to say that the region as a whole forms an ecosystem and landscape that is as least as healthy and productive as the one that existed before it.

Environmental challenges posed by massive operations that strip-mine forests and extract bitumen embedded in sand beneath are proving as vast as Alberta's tar sands region, an area the size of Florida.
The removal of the bitumen from the sands and the use of tailings as the base of the ponds and lakes means the chemistry underground will be very different from the region's normal state, raising questions about water flows and their effects on native plants and species, they say.
The Athabasca River rises from the Columbia Icefield in the Canadian Rockies and flows 956 miles north and east through mountains, prairies, forests and peat bogs into Lake Athabasca on the far northeast border between Alberta and Saskatchewan in Wood Buffalo National Park.

 Tar Sands • Hubbert Peak of Oil Production
Alberta's oil sands comprise one of the world's two largest sources of bitumen; the other is in Venezuela.
The Athabasca oil sands in northern Alberta contain an estimated 870 billion to 1.3 trillion barrels of oil -- an amount equal to or greater than all of the conventional oil extracted to date.
Residents of northern Alberta have engaged in activist campaigns to close down the oil sands plants because of devastating environmental problems, including displacement of native people, destruction of boreal forests, livestock deaths, and an increase in miscarriages.

Areas in which these sands are at or near the surface contain in excess of 40 billion barrels of recoverable oil, about the same amount as the proved crude oil reserves of North America.
In the Athabasca Project, the sands are put through a series of processes, which remove the oil and return clean white sand to the mined areas.
The sequence of operations is as follows: The bituminous sands are delivered by the belt conveyor from the bucket wheel to the extraction unit.

 Alexander's Gas & Oil Connections - Could Canada's tar sands prove the ultimate anti-OPEC resource?
For decades, they have been complaining that the official bean-counters have unfairly neglected the energy trapped in the Athabasca tar sands of Alberta-rock formations laced with hydrocarbons that can be mined and processed to yield barrels of oil.
An article declared recently that some 180 bn barrels of oil trapped in those tar sands should now be considered economically viable, and so classified as "conventional" oil.
If the country's tar sands are ever to yield their bounty to the world's consumers, producers must overcome technical obstacles in three areas: complexity, cleanliness and cost.

 Oil (Tar) Sands
Today these oil sands are recovered in open-pit mines by truck-and-shovel operations in which the world's largest Caterpillar 797 and 797B trucks have payloads of 380 tons.
Oil sand is transported to processing plants, where hot or warm water separates the bitumen from the sand, followed by dilution with lighter hydrocarbons and upgrading to synthetic crude oil (SCO).
About 20 percent of the oil sands reserves in Alberta are recoverable by surface mining; in-situ technologies (such as Steam Assisted Gravity Drainage, or SAGD, and Cyclic Steam Stimulation, or CSS) need to be used for the remaining 80 percent of the oil sands that are buried at depth (greater than 75 meters).

The Athabasca tar sands project in Alberta, coupled with the lack of a made-in-Canada energy strategy, could soon prove to be an albatross for the new Harper government.
The tar sands, however, could contain as much as 2.5 tn barrels of oil, but new and questionable technologies would be required to access these reserves at enormous financial and environmental costs.
Moreover, tar sands developments will require huge amounts of natural gas to extract the deeper reserves of oil from the bitumen and process it as crude oil.

Hot water and caustic soda (NaOH) is added to the sand, and the resulting slurry is piped to the extraction plant where it is agitated and the oil skimmed from the top.
Provided that the water chemistry is appropriate to allow bitumen to separate from sand and clay, the combination of hot water and agitation releases bitumen from the tar sand, and allows small air bubbles to attach to the bitumen droplets.
As traditional or conventional sources of oil suffer from depletion, new sources of oil such as tar sands will increasingly be relied upon to make up the difference in future global oil production.

In terms of the social costs, the dramatic expansion of the tar sands development has created labour shortages, exacerbated by infrastructure shortages in Fort McMurray, that increase the cost of living in the area.
As the tar sands consume the gas, the province is already returning to coal for power, and losing value-added jobs in the petrochemicals sector.
As that clean source of fuel expires, the tar sands are turning to non-conventional gas sources, all of which have higher social and environmental costs: the Mackenzie Valley pipeline, coal-bed methane, and in-situ (extraction of the gas from the bitumen).

 Oil Sands: Interesting Thing of the Day
Once separated from the sand and minerals, the crude oil is sometimes referred to as heavy oil, though that term is often used interchangeably with “oil sands” or “tar sands” as well.
Most of the oil sands are not on or near the surface of the ground; workers must sometimes dig 200 feet (61m) or more to reach the deposits.
Once the sand and water are removed, the bitumen must be processed further under high heat to remove impurities and break it down into a more useful and smoother-flowing oil.

To pick just one example among many, finding costs are essentially zero for the 3.5 trillion barrels of oil that soak the clay in the Orinoco basin in Venezuela, and the Athabasca tar sands in Alberta, Canada.
Tar sands, by contrast, are simply strip mined, like Western coal, and that's very cheap--but then you spend another $10, or maybe $15, separating the oil from the dirt.
To do that, oil or gas extracted from the site itself is burned to heat water, which is then used to "crack" the bitumen from the clay; the bitumen is then chemically split to produce lighter petroleum.
