  2. Oil sands - Wikipedia

    en.wikipedia.org/wiki/Oil_sands

    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. [27]

    en.wikipedia.org/wiki/Environmental_issues_in_Canada

    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.

  4. Environmental issues in Alberta - Wikipedia

    en.wikipedia.org/wiki/Environmental_issues_in...

    Raw bitumen extracted from the oil sands in northern Alberta is shipped in Canada and to the United States through pipelines, railway, and trucks. Environmental concerns about the unintended consequences of the oil sands industry are linked to environmental issues in the rest of Canada. While pipelines are considered to be the most efficient ...

    This is the only reported instance of human remains found within tar pits. [25] For thousands of years, Native Americans used tar from the La Brea Tar Pits as an adhesive and binding agent. [1] They would use it as waterproof caulking to line their boats and baskets.

    Their carbon footprints, however, are radically different: conventional reservoirs use the natural energy in the environment to flow oil and gas to the surface unaided; unconventional reservoirs require putting energy into the ground for extraction, either as heat (e.g. tar sands and oil shales) or as pressure (e.g. shale gas and CBM).

  8. Tar - Wikipedia

    en.wikipedia.org/wiki/Tar

    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]
