Tar sands have affected over 75% of the habitat in the Alberta taiga forest due to the clearing of the forests and the oil ponds that come from the extraction. These tar sands also create awful toxic oil ponds that affect wildlife and surrounding vegetation. Oil extraction also affects the forest soil, which harms tree and plant growth.
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]
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).
Tar sands get a lot of bad press, much of it to do with the fact that the extraction and processing of tar sands bitumen creates a lot more pollution than other fuel sources. A few companies are ...
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]
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 ...
In 1977 Strausz published his article on the chemistry of the oil sands, then also known as the tar sands attending the conference that year entitled the Symposium on Tar Sand and Oil Shale. [ 6 ] By 2003 with the rising price of oil , and the improvement of enhanced recovery techniques such as thermal in-situ methods, the Peace River oil sands ...
