Suncor extracts and upgrades bitumen using the following process: Hot water is used to separate the bitumen from the sands. This step is called extraction and is not required for in situ bitumen. Bitumen is heated and sent to drums where excess carbon (in the form of petroleum coke) is removed.
The majority of Alberta’s oil sands—about 90%—are too far below the surface to be quarried. Accessing the oil in these deposits requires a method of extraction that can work without having to remove the oil sands from the ground.
Getting Oil Sands Out of the Ground. Oil sands are recovered using two methods, depending on the depth of the reserves. Surface mining is used when bitumen is within 250 feet of the surface. In-situ recovery techniques are used to extract deep deposits of bitumen without removing the soil and materials above it.
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.
Oct 21, 2013 Oil sands are exploited by injecting high-pressure steam into the earth or by strip mining to extract the sticky bitumen, which is then washed away from clay and sand…

Oil Sands Upgrading Chair Asphaltenes in Bitumen Dilution of Alberta bitumens in n-pentane or n-heptane gives 10-20% of brown/black solid precipitate This fraction is called “asphaltene”, contains highest molecular weight (up to 5000) and most polar components in the oil Asphaltenes are very reactive during processing
sands) are being utilized. Oil sands contain bitumen, which can be processed into a synthetic crude oil. A region of boreal forest in Alberta, Canada, that covers a deposit of oil sands will be cut and removed during the process of bitumen extraction. It is estimated that the deposit contains 73 billion barrels of recoverable bitumen.
The Horizon Oil Sands include a surface oil sands mining and bitumen extraction plant, complemented by on-site bitumen upgrading with associated infrastructure to produce high quality SCO. In late 2017, the Phase 3 expansion was completed at Horizon, the final step in the Company's transition to a Long Life Low Decline asset base.
Dec 18, 2013 Common extraction methods include surface mining—where the extraction site is excavated—and “in-situ” mining, where steam is used to liquefy bitumen deep underground. The largest deposits of tar sands are found in Alberta, Canada.
The oil sands under discussion underlay a vast region of Alberta.To extract oil from these oil sands (also called tar sands, especially in the United States, because of the stuff's sticky-goo quality) typically requires mining the heavy, viscous, tar-like hydrocarbon locked up in these deposits la coal. Once extracted, the oil sands go through a separation process to get rid of the sand ...
Using the IL trioctylammonium oleate ([HN888][Oleate]) at a 1:3 IL:oil sand mass ratio, we were able to achieve bitumen extraction from high grade Alberta oil sands of ca. 100% with low solids ...
Surface mining is a technique used to obtain bitumen from oil sands where the oil sands deposits are located fairly close to the surface. If the reserves are shallow enough, earth moving equipment can dig out oil sand for processing. These deposits must be within 75 meters of the surface to be mined in this fashion. Resources recoverable by this type of extraction are estimated to be 65 ...
Apr 11, 2019 Instead, a huge area about the size of Florida or Wisconsin north and east of Edmonton, Alberta, contains a tarry bitumen mixed with sand that is mined from underneath the boreal forest.
The Alberta tar sands hold much of Canada’s oil wealth: the region contains an estimated 1.7 trillion barrels of bitumen oil. The size of this reserve makes it the third largest oil deposit in the world after Venezuela and Saudi Arabia. Yet despite this, the cost of extraction now …
It is composed of sand, claw, water, and bitumen, which is an oil that is black and viscous. These sands can be mined, and then processed, to remove the bitumen. Once processed, then bitumen can be then refined into oil. It is a complex process of extraction and separation that is often harvested through strip mining and underground heating.
Jul 09, 2014 The tar sand fields of Alberta, Canada is the third largest bitumen deposit in the world. Tar sands are a combination of clay, water, and bitumen, a heavy black toxic oil. The tar sands are being mined and processed to extract bitumen, which is then refined into oil. This particular tar sand deposit cannot be pumped from the ground, so it has ...
The Athabasca oil sands are the largest segment of the economy in Alberta, making up just over 30 percent of the gross domestic product. In the 2013–2014 fiscal year, the Alberta government reported that “synthetic crude oil and bitumen royalty [from oil companies] accounted for about $5.2 billion or almost 55 per cent of Alberta’s $9.6 ...
Water-based bitumen extraction technology from mineable oil sands faces major challenges of high water usage and tailings disposal. In the present study, a process for solvent extraction of bitumen from Athabasca oil sands was investigated. In this process, oil sand is mixed with light hydrocarbon solvents, and the solvent–bitumen solution is separated from the mineral solids by centrifugal ...
Sep 01, 2010 The overburden is used to build haul roads and tailings dikes, while the oil sands, thick and heavy with tarry bitumen, are piled high in long benches using hydraulic or electric rope shovels ...
Roughly 500 km 2 of the 140,000 km 2 oil sands deposit in Northern Alberta is currently undergoing surface mining activity. This is about 3% of total oil sands surface area or 20% of oil sands reserves. Surface mining uses truck and shovel technology to move sand saturated with bitumen from the mining area to an extraction facility.

Bitumen extraction. Syncrude separates the bitumen from the sand using a warm-water extraction process at the Mildred Lake facility, which processes oil sand together with oil sand slurry from the North mine and Aurora froth, which arrives via the hydrotransport system.
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 the bitumen from deep within the earth (OSDC 2008c).
Extraction of heavy oil called bitumen is an important component of Canada’s economy. Alberta provides over 15% of Canada’s GDP and almost a third of that is from resource extraction. Unfortunately Canadian oil resources are more difficult and expensive to extract, with higher environmental consequences than many other world crude oil ...
