Advanced extraction techniques, such as oil sands mining and in situ development, are used to recover heavier oil that does not flow on its own. Oil found in geological formations that make it more difficult to extract, such as light tight oil (LTO), is also called unconventional oil because non-traditional techniques are needed to extract the oil from the underground reservoir. In Situ Methods used in the Oil Sands. In situ methods are used to recover bitumen that lies too deep beneath the surface for mining (about 80% of the oil sands in Alberta). The success of in situ methods depends on the resolution of two major issues: 1) reducing the viscosity of bitumen so that it will flow, and 2) recovering Oil Sands Extraction The Corporation continues to review several potential extraction techniques for development of its resources. These range from the widely-used methods of Steam Assisted Gravity Drainage ("SAGD") and Cyclic Steam Stimulation ("CSS") and more experimental solvent techniques. Tar sands are primarily, aggregates of sands, clay that is rich in minerals, heavy oil and Extraction techniques involved heating of the tar sand samples to a temperature of 140 oF in order to reduce the apparent viscosity of the tar sand. This method of extraction makes use of a coupling agent known as sulphunated fatty acid, alkali metal Suppose we drill horizontals across this field (sideline to sideline) such that after full combustion and extraction has been completed, each chalked 5 yard line or five meter line as the case may be, represents a solid existing barrier of undisturbed oil sand all the way to the bottom of the reservoir.

NIST/SEMATECH e-Handbook of Statistical Methods, 2012. 20 Aug 2019 Canadian researchers have developed a large-scale economical method to extract hydrogen from oil sands (natural bitumen) and oil fields. Tar sands can be mined and processed to extract the oil-rich bitumen, which is As a result of this difference, extraction techniques for the tar sands in Utah will 24 Jan 2017 to include details about in situ extraction, which is different from the mining method and makes up about half of Canada oil sands production. 7 Jan 2015 The oil sands are a mixture of sand, clay, water and extra heavy oil. Extraction is, however, a complex operation that raises environmental issues. is the case for 80% of Canada's oil sands, thermal methods are used. 29 Aug 2016 Canada's oil sands are notoriously dirty, but in situ extraction—which of this extraction method could be damaging, the Alberta government 27 Nov 2012 Extracting underground or “in situ” oil sands is especially energy stop was to see an example of one of the two main extraction techniques
