Economic Contribution. A strong energy sector is key to ensure Canada's prosperity for the future. Canada is falling behind. Competition for capital investment in the global market is fierce and if Canada wants its industry to be a major player internationally, a number of factors need to be considered.
The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of bitumen or extremely heavy crude oil, located in northeastern Alberta, Canada – roughly centred on the boomtown of Fort McMurray.These oil sands, hosted primarily in the McMurray Formation, consist of a mixture of crude bitumen (a semi-solid rock-like form of crude oil), silica sand, clay minerals, and water.
Oil Sands: Sand and rock material which contains crude bitumen (a heavy, viscous form of crude oil). Oil sands are found primarily in the Athabasca region of northern Alberta, Canada, and in areas ...
However, despite the extraction costs of oil from tar sands, in today's current market, with the purchase price of oil at $80 per barrel, the production of petroleum from tar sands is still an extremely profitable affair for companies mining Canadian tar sands. Yet, we are only addressing the question of economics.

The pros and cons of tar sands show us that short-term gains happen, but at the expense of long-term problems. We must work to find a solution that will limit emissions and habitat damage to benefit from this natural resource. If we cannot find this solution, we may run out of bitumen one day and leave a more polluted planet for future generations.
The average well now uses 5,500 tons of frac sand per well, up from 5,250 at the end of Q1 (this is contradictory evidence to Halliburton who stated that average sand per well dropped in Q2. After the Halliburton call, analysts speculated it was a temporary blip as operators had to cut back as sand was in such short supply).

The oil sands can be extracted using open mining at the surface. New methods of the 1990's improved the efficiency of the mining which reduces the cost. The systems use large hydraulic and electrically powered shovels to dig the sands up and load them into gigantic dump trucks. The trucks carry up to 320 tons of tar sand per load.
What are Oil Sands? Oil sands, also known as "tar sands," are sediments or sedimentary rocks composed of sand, clay minerals, water, and bitumen. The oil is in the form of bitumen, a very heavy liquid or sticky black solid with a low melting temperature.
The cost to produce oil in the oil sands is made up of the upfront capital cost required to first construct a facility, the cost to operate a facility once it is online, and the periodic cost to sustain production by replacing worn out equipment or parts or, in case of in situ projects to drill new wells pairs over time.
In order for mining to be economically feasible, the deposit must be located relatively close to the surface, typically no more than 50 meters deep. Once mined, oil sands is mixed with water to produce a pumpable slurry that can be gravity separated. Learn more about bitumen production from mined oil sands.
Today, about 59% of the oil consumed in the United States are imported. The deposits of oil sands (oil shale) in the United States are massive. The processing of oil shale has gone through cycles of development and commercialization, all without achieving a competitive cost of production. As well, tar sands are processed on a limited basis.

The Alberta government estimated that in 2012, the supply cost of oil sands new mining operations was $70 to $85 per barrel, whereas the cost of new SAGD projects was $50 to $80 per barrel. These costs included capital and operating costs, royalties and taxes, plus a reasonable profit to the investors.

A key area of controversy over mining in the boreal region is the exploitation of tar (or oil) sands, which are areas with sand or sandstone saturated with bitumen, a viscous form of petroleum, which can be mined and processed to produce oil. Tar sands are extracted by either surface (open pit) mining or in-situ extraction. For surface mining, areas are first cleared of trees, bogs are drained ...
Learn more at Oil sands and GHGs. Canada, with 0.5 per cent of the world's population, produces about two per cent of global CO 2 emissions. Oil sands account for 10 per cent of Canada's GHG emissions and about 0.15 per cent of global GHG emissions.
Tar sands also impact water supplies. For every gallon of gasoline produced by tar sands, about 5.9 gallons of freshwater are consumed during the extraction, upgrading, and refining process. That's roughly three times as much as used for conventional oil. Much of this water is polluted by toxic substances harmful to human health and the ...
