oil and bitumen deposits in Canada

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. The Athabasca deposit is the largest known reservoir of crude bitumen in the world and the largest of three major oil sands deposits in Alberta, along with the nearby Peace River and Cold Lake deposits (the latter stretching into Saskatchewan).Together, these oil sand deposits lie under 141,000 square kilometres (54,000 sq mi) of boreal forest and muskeg (peat bogs) and contain about 1.7 trillion barrels (270×10^9 m3) of bitumen in-place, comparable in magnitude to the world's total proven reserves of conventional petroleum. The International Energy Agency (IEA) lists the economically recoverable reserves, at 2007 prices and modern unconventional oil production technology, to be 178 billion barrels (28.3×10^9 m3), or about 10% of these deposits. These contribute to Canada's total proven reserves being the third largest in the world, after Saudi Arabia and Venezuela's Orinoco Belt.By 2009, the two extraction methods used were in situ extraction, when the bitumen occurs deeper within the ground, (which will account for 80 percent of oil sands development) and surface or open-pit mining, when the bitumen is closer to the surface. Only 20 percent of bitumen can be extracted using open pit mining methods, which involves large scale excavation of the land with huge hydraulic power shovels and 400-ton heavy hauler trucks. Surface mining leaves toxic tailings ponds. In contrast, in situ uses more specialized techniques such as steam-assisted gravity drainage (SAGD). "Eighty percent of the oil sands will be developed in situ which accounts for 97.5 percent of the total surface area of the oil sands region in Alberta." In 2006 the Athabasca deposit was the only large oil sands reservoir in the world which was suitable for large-scale surface mining, although most of this reservoir can only be produced using more recently developed in-situ technology. ....

Transportation in Athabasca oil sands

Canada is the largest source of oil imported by the United States, supplying nearly 1 million barrels per day (160,000 m3/d) from oil sand sources. Keystone XL, a pipeline from Alberta to Gulf coast refineries, is under consideration, as is the North Gateway project to Kitimat, British Columbia, which would be built by Enbridge, operator of the Enbridge Pipeline System which also serves the area. Industry observers believe there may be excess pipeline capacity. Kinder Morgan has made another proposal for a west coast pipeline while Enbridge also proposes Eastern Access, a pipeline to refineries in Montreal and possibly to a terminal in Portland, Maine, as well as expansion of an existing pipeline to Chicago. Environmental and First Nations opposition to all these projects is anticipated, and planned.
