The name tar sands was applied to bituminous sands in the late 19th and early 20th century. [18] 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. [19]
The Athabasca oil sands, also known as the Athabasca tar sands, are large deposits of oil sands rich in bitumen, a heavy and viscous form of petroleum, in northeastern Alberta, Canada. These reserves are one of the largest sources of unconventional oil in the world, making Canada a significant player in the global energy market.
Oil sands, often pejoratively referred to as tar sands, are a phenomenon unique to the tundra environment and are profitable and plentiful in the Athabasca region of the Alberta sands. [16] Oil sands consist of bitumen, which contains petroleum, found in a natural state combined with clays, sands, and water. [ 16 ]
The Melville Island oil sands are a large deposit of oil sands (sometimes referred to as tar sands) on Melville Island in the Canadian Arctic Archipelago. [ 1 ] [ 2 ] Exploration for petroleum deposits in the Canadian Arctic Archipelago began, on Melville Island, in 1961. [ 3 ]
The use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. [1] The value of a resource is a direct result of its availability in nature and the cost of extracting the resource. The more a resource is depleted the more the value of the resource increases. [2]
The agreement called for mining 45,000 tonnes of sands in 1937 and 90,000 tonnes each year after 1938. The 1,555- hectare lease carried a rental of $2.47 per hectare per year. There was to be royalties of $0.063 per cubic metre on production for the first five years, and $0.31 per cubic metre thereafter.
One can produce a tar-like substance from corn stalks by heating them in a microwave oven. This process is known as pyrolysis. Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat. [1]
Tar sands can be described as areas on land containing an unconventional mixture of sand, clay, water, and a petroleum based residue called bitumen, that is useful to produce crude oil. [48] In the NDRC article it mentions that Canada is currently one of the largest depositors of crude oil in the world.
