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]
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.
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 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 ]
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]
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).
Apparently as of October 2013 "Tar Sands" is the colloquial and common term in the USA, as evidenced by Dick Cheney's use of it when actually promoting Tar Sands development and Keystone XL. The article makes note of "Oil Sands" as a term used only within Canada, and only by promoters of these projects.
Small tar pit. La Brea Tar Pits is an active paleontological research site in urban Los Angeles. Hancock Park was formed around a group of tar pits where natural asphalt (also called asphaltum, bitumen, or pitch; brea in Spanish) has seeped up from the ground for tens of thousands of years. Over many centuries, the bones of trapped animals have ...
