Oil extraction from sand
Extracting oil from U.S. public lands through oil shale or tar sands would deal a The BLM's 2013 decision to open these public lands to oil shale and tar sand Canada's oil sands deposits are mainly located in northern Alberta, and at Water use has been and will continue to be reduced in the extraction process. 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 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 12 Jan 2017 If all the oil sands were extracted in Alberta, the emissions would be equivalent to burning all the oil in Saudi Arabia — the world's largest oil
In Canada extraction of oil from oil sand is conducted thus: 1. In the open (career) way at localisation of oil sand to 100 metres depth; 2. Drilling of chinks at
Large shovels scoop the oil sand into trucks which then move it to crushers where the large clumps of earth are processed. Once the oil sand is crushed, hot water is added so it can be pumped to the extraction plant. At the extraction plant more hot water is added to this mixture of sand, clay, bitumen, 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, These features make it possible for hydrocarbon extraction from oil sands feedstock at mild temperatures of 50-60 C degrees with no vacuum or pressure applied. There's no need for tailings ponds because the only elements that leave the closed-loop system are the extracted crude oil and the cleaned sands, which can be placed back in the earth or sold as clean sand for construction or fracking purposes. Tar sands take 3 barrels of water to process every barrel of oil extracted. Ninety percent of this water becomes so toxic that it must be stored in tailing ponds. Unfortunately these ponds Water Impacts : The extraction of bitumen from oil sands requires a large amount of water, and thus water use is a concern when looking at oil sands extraction. Water used in the oil sands can be recycled, but only small amounts of this water are returned to the natural cycle. Large shovels scoop oil sand into haul trucks that transport it to crushers where large clumps are broken down. The oil sand is then mixed with hot water and pumped by pipeline to a plant called an upgrader, where the bitumen (oil) is separated from the other components such as sand, clay and water.
The method used to extract bitumen from an oil sand depends upon how deeply to the surface, it will be mined and hauled to a processing plant for extraction.
Extraction separation cell. Suncor's primary extraction plants separate raw bitumen from the sand in giant separation cells. Truck and shovel mining

20 Mar 2011 The process can also be used to extract oil and tar from beach sand after oil spills , such as the Exxon Valdez and Deepwater Horizon incidents. 25 Sep 2014 Most of the current extraction process takes place in open-pit mines, with Oil at the first phase of separation from the sand at the Suncor tar 22 Sep 2009 This unconventional oil is currently extracted using surface mining or in situ (in place) drilling methods, depending on the depth of the deposit. 1 Dec 2008 Falling energy prices could squeeze oil-extraction research. The huge run-up in oil prices over the last several years, reaching a peak of close

10 Dec 2012 More and more petroleum is flowing from Alberta's vast oil sands deposits roughly 12 barrels of water to separate one barrel of it from the sand, be all the energy required to extract the oil from the tar sands—the burning of 19 Feb 2013 Thanks to high global oil prices, industry can afford the large amount of energy needed to extract the oil and turn it into a usable fuel. 4 Nov 2014 Shallow deposits can be extracted using open pit mining but most oil sand reserves are located too far underground and require unconventional extra heavy sour crude oil extracted from tar sands will result in higher air emissions of The consequences of tar sand oil extraction (as opposed to refinement)
