Search Britannica is the by-product of extracting oil from oil sands Tar Sands Extraction. Alberta’s Athabasca tar sands lie under about 142,000 square kilometers of land, much of which is locked deep underground, making it hard to extract (CAPP, 2017). Tar sands are known as one of the dirtiest forms of fossil fuel because of the vast economic and environmental costs that are associated with its extraction. Oil sands are actually found all over the world, and are sometimes referred to as tar sands or bituminous sands. A typical oil sands deposit in Alberta contains on average about 10% bitumen, 5% water and 85% solids, mostly in the form of coarse silica sand. Oil sands also contain fine solids and clays, typically in the range of 10 to 30% by weight. A hot water extraction process for extracting bitumen from tar sands is taught wherein the tar sand is conditioned using an alkali metal bicarbonate, an alkali metal carbonate and a liquid hydrocarbon. A source of calcium and/or magnesium ions can also be added. The conditioning step replaces the step of conditioning using caustic soda previously used in tar sand extraction. Dr. Karl Clark, chemist and oil sands researcher, perfected and patented a hot water separation process while working for the Research Council of Alberta and the University of Alberta in 1926. It became the basis of today's thermal extraction process. In the early days of discovery, oil sands were incorrectly referred to as tar sands.
9 Nov 2019 Oil is produced (extracted) using different methods depending on several fields in Alberta including Cardium and Viking; and the Montney and Oil recovery in the oil sands uses two main methods: mining or in situ, 18 Dec 2013 Extracting bitumen from tar sands—and refining it into products like gasoline—is The largest deposits of tar sands are found in Alberta, Canada. While tar to the energy intensive extraction, upgrading, and refining process.

These are spread under about 4,800 km2 of the Athabasca oil Tar sands, which can produce 20 percent more greenhouse gas emissions in total the expense of extracting and refining that oil (and the pollution the process Keystone XL pipeline, which would carry Alberta's tar sands oil to the States).
26 Apr 2014 An oil tar sands plant in Fort McMurray, Alberta, Canada Particularly energy intensive to process, tar sands oil was found in one Stanford operations that they began to question the extraction of oil near their property. 12 Feb 2020 Oil has made Alberta one of the wealthiest regions in North America, but the process of extracting petroleum from oil sands releases an PETROTEQ'S PATENTED OIL SANDS EXTRACTION TECHNOLOGY IS A ( such as the oil sands projects in Alberta, Canada) or the "oil-wet" deposits such as the Petroteq's extraction technology utilizes no water in the extraction process, 14 Apr 2018 Surface mining is a technique used to obtain bitumen from oil sands where by this type of extraction are estimated to be 65 billion barrels in Alberta. Process. To excavate the oil sand, large trucks use scoops (some with process. While Alberta's oil sands proven reserves are currently stated to be extraction method utilized – surface mining or in-situ – companies proposing a. tional oil, the water-based extraction process produces ex- tremely large volumes ated with Alberta oil sands and gives direction on which streams would most major bitumen producers using primarily surface mining methods with in situ methods on the rise.

Karl Clark’s work for the Research Council of Alberta concentrated on developing the hot water method of separating the oil sands into its component parts.When mixed with hot water, the oil sands separates into layers, with the most dense—the sand—sinking to the bottom, and the least dense—the water—rising to the top.
