Oil sands extraction ppt

Oil sands extraction can affect the land , water and air. The land affect when the bitumen is initially mined. The water resources by its requirement for large quantities of water during separation of the oil and sand. The air due to the release of carbon dioxide and other emissions.

20 Dec 2011 Biodiesel-Assisted Ambient Aqueous Bitumen Extraction (BA3BE) from Athabasca Oil Sands. Energy & Fuels 2018, 32 (6) , 6565-6576. DOI:  One method is similar to coal extraction and involves underground, open-pit, or strip mining. Unlike coal production, however, this method of oil shale production   28 Aug 2019 In 2012 in situ production surpassed mining as the dominant extraction method and this trend is expected to continue, with in situ accounting for  The oil sands are then transported to extraction plants, where bitumen (heavy oil) is separated from the sand. A company might decide to sell its extracted

The current method for the recovery of bitumen from the oil sands via surface mining results in the accumulation of large volumes of fluid wastes (tailings—a  There are two primary extraction methods for tar sands: Mining: Open-pit mining is the most common form of tar sands extraction. This method requires the use  PETROTEQ'S PATENTED OIL SANDS EXTRACTION TECHNOLOGY IS A BREAKTHROUGH FOR THE OIL SANDS INDUSTRY. Petroteq Energy Inc. has  4 Nov 2014 Oil sands -- tar sands or bituminous sands -- are made up of sand, water, SAGD is the most common extraction method used in Canada but  12 Jan 2017 Strip-mining the boreal to extract the tar sands and processing the oil Fracking is a method of drilling that allowed energy companies to 

Because the oil sand found on Syncrude's leases is not deeply buried, surface mining is the most viable method of recovery. First, muskeg and overburden are 

Tar sands mining represents the most intensive and environmentally damaging method of oil extraction in Alberta, involving the drastic alteration of surface and  25 Sep 2014 Giant dump trucks haul raw tar sands at the Suncor tar sands mining operations near Fort McMurray, Alberta, on September 17, 2014. #. Tar sands are the dirtiest source of oil on Earth. This extreme from the sand. The in situ method, used Tar sands extraction is extremely water-intensive. it.

of SAGD, CHOPS and PPT have been the major directions of technical the Heavy Oil Belt and Oil Sands deposits in Alberta and. Saskatchewan (Figure 2). extraction technologies, and the definition of what is a resource may vary from  

as oil sands or tar sands) and the concerns of resident First Nations regarding the environmental effects of the development of this resource. As described in the student material this has become a major issue and could have significant impact on the plans for oil sands development. This review discusses briefly the history, principle and applications of extraction with supercritical gases, for example, removing vanadium from heavy oil, extracting oil from oil sands 2. Oil Sands Throughput. Each Extraction plant is designed for a certain oil sands throughput assuming an average ore grade. If an excessive amount of oil sands is processed through the Extraction plant (above the design capacity), the residence time within the gravity separation vessel is proportionally reduced and bitumen recovery rates may

This review discusses briefly the history, principle and applications of extraction with supercritical gases, for example, removing vanadium from heavy oil, extracting oil from oil sands

19 Feb 2016 This method requires the drilling of two horizontal wells, one slightly higher than the other, through the oil sands deposit. Steam is injected  9 Nov 2019 Advanced extraction techniques, such as oil sands mining and in situ This method pumps steam down a vertical well to soak or liquefy the  Although mining impacts are severe, from a land impact perspective, will be dwarfed by the impacts of deep oil sands development. ▫ Oil sands are composed of 

What are Oil Sands? Oil sands, also known as "tar sands," are sediments or sedimentary rocks composed of sand, clay minerals, water, and bitumen. The oil is in the form of bitumen, a very heavy liquid or sticky black solid with a low melting temperature. Bitumen typically makes up about 5 to 15% of the deposit. Many are being affected by the oil sands’ development, suffering consequences that range from land rights or health issues to loss of livelihood. One example is a legal challenge by the Beaver Lake Cree Nation that maintains the boom in tar sands extraction is destroying their hunting and fishing lands. They say that caribou, elk, moose, deer Environmental impacts of oil sands The environmental impact of the oil sands is an issue that has been extremely divisive. As with the extraction and use of any fossil fuel , negative environmental effects arise as a result of the extraction, upgrading , and processing of bitumen from the oil sands.
