As of 2011, the oil sands reserves stand at around 169 billion barrels.

Alternatives to natural gas exist and are available in the oil sands area.

"In the oil sands, we may see overall emissions still increasing by 4 to 6 percent a year."

What that has to do with the oil sands is utterly unclear.

"So why are the Canadian oil sands going to be developed?

The name was derived from the fact that four paying oil sands were believed to be present in the area.

It is notable as the original home of oil sands mining.

Industry is the core force of oil sands development.

The Sunrise oil sands project entered the development phase in 2012.

Oil sands and mud volcanoes are especially common in this area.

Its oil sands output averaged 248,000 barrels a day last month.

He also worked to create stronger relationships between the oil sand operators and university researchers.

For all of these reasons, some groups have labeled the oil sands an environmental menace.

Shell Canada is making this technology available free of charge to other oil sands production companies.

Over all, oil sands production is scheduled to triple during this decade.

In fact, the problem with tar sands is not just the emissions.

Tar sands are awful (and I work for an oil company).

To process these tar sands into oil, will use vast amounts of energy and water.

He is trying to pass the dirty tar sands oil off, as clean energy.

The damage from the tar sands project, can never, ever be cleaned up.

Tar sands are about 2:1 which is also a bad investment of scarce energy.

Are we going to invade Canada for the tar sands?

But we have the facts on tar sands now, so I do not see any reason to delay.

Where are the tar sands proponents grandchildren going to live.

The production of tar sand is the main cause.

Yet many in the oil industry are betting that the tar sands moment really has arrived this time.

The tar sands represent just one example of incredible environmental destruction.

The tar sands are among the least efficient fuels on the planet.

Actually, there are pro's and cons of the tar sands.

That brings me to this question of tar sands and oil shale.

Canadian tar sands are not the solution to America's energy needs or economic woes.

Buy tar sand oil from a liberal, western democracy.

Tar sand deposits and all natural gas properties were in Alberta.

Who wants to hit the pipeline here and at the tar sands of Athabasca?

The tar sand is more toxic than crude oil.

Perhaps that is why you think tar sand extraction is a good idea.

The problem with this pipeline is that tar sands aren't a very nice way to get oil.

The second way is to look beyond conventional reserves to unconventional ones, like the tar sands.

The plan would also halt new tar sands development until emissions have been capped.

The tar sands spill will cost at least $700m to clean up.

In the Cold Lake area it contains bituminous sands.

Investment in the bituminous sands in northern Alberta - the world's last great oil field - totals approximately $200 billion.

The name tar sands was applied to bituminous sands in the late 19th and early 20th century.

Bituminous sands are a major source of unconventional oil, although only Canada has a large-scale commercial oil sands industry.

It was the first ever drilling for oil, but without much success: Meyn found only bituminous sands and oil pastels.

The Danish king later granted him the exploitation rights for the bituminous sands, which produced from 1858 bitumen, axle grease and petroleum.

Oil sands, tar sands or, more technically, bituminous sands, are a type of unconventional petroleum deposit.

(PL) Mr President, Commissioner, global reserves of bituminous sands are very extensive.

Companies which make profits from the processing of bituminous sands must allocate some of these profits to environmental protection, for example in the form of a deposit.

In Canada, BP is involved in the extraction of oil sands, also known as tar sands or bituminous sands.

The pipeline carried bituminous sands oil from Canada into the United States in a diluted bitumen (dilbit) formulation which separated upon spilling.

The 14 to 17% excess emissions are a full lifecycle figure (well to wheel, everything from digging the bituminous sand out of the ground to burning the fuel produced from it).

Historically known as bituminous sands or sometimes as "tar sands", the deposits were exposed as major rivers cut through the oil-bearing formations to reveal the bitumen in the river banks.

Jacob Owen Absher: In the mid-1920s, a remarkable and persistent experimenter named Jacob Owen Absher incorporated the Bituminous Sand Extraction Company.

People who saw the bituminous sands during this period were familiar with the large amounts of tar residue produced in urban areas as a by-product of the manufacture of coal gas for urban heating and lighting.

Part of the river at the Morrow Lake delta remained closed and other sections of the river remain restricted because of the ongoing cleanup of the bituminous sands oil product called diluted bitumen (dilbit) oil the pipeline had been transporting.

In 1978 he started a pioneer project based on the use of modelling in hydraulic fracturing, and in 1984 he focused his attention on a project aimed at investigating complex intercurrent processes in the in-situ thermal recovery of bituminous sand.

In 2013, in opining on the Keystone XL pipeline proposal, the EPA recommended to the State Department that pipelines that carry bituminous sands oil should no longer be treated just like pipelines that carry any other oil.

Despite the large reserves, the cost of extracting the oil from bituminous sands has historically made production of the oil sands unprofitable-the cost of selling the extracted crude would not cover the direct costs of recovery; labour to mine the sands and fuel to extract the crude.

The Athabasca oil sands first came to the attention of European fur traders in 1719 when Wa-pa-su, a Cree trader, brought a sample of bituminous sands to the Hudson's Bay Company post at York Factory on Hudson Bay where Henry Kelsey was the manager.
