Extraction process of oil sands

The first process to extract bitumen from oil sands on a commercial scale, developed in the 1920s by Dr Karl Clark, a scientist involved in hot water extraction, 

Feb 19, 2016 This method requires the drilling of two horizontal wells, one slightly higher than the other, through the oil sands deposit. Steam is injected  Suncor's oil sands business recovers bitumen through surface mining and steam injection technologies and upgrades it into refinery-ready crude oil products. Nov 9, 2019 The first efforts to tap the oil sands resource began in the mid 20th century using hot water to separate bitumen from sand. Since then the process  To process it into usable fuel requires complex upgrading and refining that is also The volume of tar sands oil, combined with the energy intensive extraction  Mining refers to the oil sands extraction process whereby large amounts of earth are removed, mixed with water and transported by pipeline to a plant, where the  Aug 16, 2012 The oil product extracted from Canada's tar sands isn't like Infographic: Explaining the process of processing / refining tar sands into oil. Dec 16, 2016 Bitumen is extracted from mined oil sands using a water intensive process known as hot water extraction [Clark, 1944]. First, at the slurry

Venezuela’s reserves of oil sands are actually referred to as “extra heavy oil”, because the microbial process that degraded the original crude oil is slightly less complete (the deposits are younger) than what occurred in Canada,

Oct 27, 2016 In both processes, bitumen is extracted from oil sands ore using the Clark Hot Water Extraction process, where hot water is mixed with crushed oil  Aug 31, 2016 abandoned the most explosive oilsands extraction ideas but major The process injects a combination of steam and solvent into an oilsands  PROCESS OVERVIEW. Petroleum products are produced from the oil sands through 3 basic steps: Extraction of the bitumen from the oil sands, where the solids and water are removed.; Upgrading of the heavy bitumen to a lighter, intermediate crude oil product.; Refining of the crude oil into final products such as gasoline, lubricants and diluents.; Traditionally, a majority of the bitumen produced Oil sands slurry produced in the Slurry Preparation Plant (SPP) contains about 50-55% sand and less than 10% bitumen. The purpose of Extraction is to recover the bitumen portion, while rejecting the heavy solids. This is achieved through a simple water-based gravity separation process, most of which Conditioning starts the process of separating sand and bitumen and breaks apart any large pieces of oil sands. The oil sand is mixed with warm water-- called a slurry-- and transported by pipeline to an extraction facility. Here, the slurry is put through a separation process where sand sinks to the bottom and impure bitumen froth rises to the

Oil sands, or tar sands, are sand and rock material which contains crude bitumen, a dense, viscous form of crude oil.Bitumen is too thick to flow on its own, so extraction methods are necessary. Our oil sands business recovers bitumen through surface mining and steam injection technologies and upgrades it into refinery-ready crude oil products. Suncor’s Upgrading operations process bitumen into higher-value synthetic crude oil and diesel fuel using two upgraders at its oil sands site in Fort McMurray. Oil sands extraction can affect the land when the bitumen is initially mined, water resources by its requirement for large quantities of water during separation of the oil and sand, and the air due to the release of carbon dioxide and other emissions. Learn about the process Suncor uses to extract bitumen from the oil sands: both surface mining as well as steam-assisted gravity drainage (SAGD) while trying to minimize our impact on the environment. Although this process is friendlier to the local habitat, the burning of natural gas to create steam increases the emission risk by another 10-15% over traditional crude extraction. The pros and cons of tar sands show us that short-term gains happen, but at the expense of long-term problems. Bitumen is too thick to flow on its own, so extraction methods are necessary. Oil sands are found primarily in the Athabasca, Cold Lake and Peace River regions of northern Alberta and Saskatchewan, Canada, and in areas of Venezuela, Kazakhstan, and Russia.

Recovering Oil Sands. Two different methods are used to produce oil from the oil sands – surface mining and in-situ – or producing in place.

The bitumen can be extracted and processed to produce an unconventional form of oil (so called to distinguish it from oil produced by the conventional method  The oil sands are strip-mined, and the bitumen is typically separated from sand and clays by an alkaline hot water extraction process.

Alberta is a hotbed of oil and gas innovation, a story that is seldom told but could change the conversation around climate and energy policy if Canadians were more familiar with them. Polymers have the potential to impact many aspects of oil sands production—from extraction to tailings management. Qi Liu serves as scientific director of the Institute for Oil Sands Innovation and is the Ron Nolan/Hatch Professor of Sustainable Energy and Mineral Process Technologies. Environmental concerns regarding oil sands mining focus on the toxic waste byproduct of the extraction process and land disturbance. After the sand is brought to an extraction plant, it undertakes a dilution process in which it is mixed with hot water and chemicals so that it may flow freely into pipelines. Before looking at the implications and drivers of this controversial practice, here is a breakdown of the complex process of extracting fuel from the oil sands. How oil is forced from the sands All wetlands in the area to be mined must first be drained, and any rivers diverted.
