Efficiency of oil sands extraction
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. 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. But tar sands oil is in a category all its own. Tar sands retrieved by surface mining has an EROI of only about 5:1, according to research released Tuesday. Tar sands retrieved from deeper beneath the earth, through steam injection, fares even worse, with a maximum average ratio of just 2.9 to 1. Energy efficiency is expected to improve to an average of 900 cubic feet (25 m 3) of natural gas or 0.945 gigajoules (262 kWh) of energy per barrel by 2015, giving an EROEI of about 6.5. Alternatives to natural gas exist and are available in the oil sands area. Alberta's oil sands contain on average about 10% bitumen, 5% water and 85% solids. Most of the solids are coarse silica sand. Oil sands also contain fine solids and clays, typically in the range of 10-30% by weight. Bitumen is a heavy complex hydrocarbon, contained within the oil sands deposit. 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. 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.

The Canadian Oil Sands Dialogue program is a calendar of member and A New Look Extracting economic value from the Canadian oil sands, November We campaign against the rapidly expanding Canadian tar sands industry, a carbon The volume of tar sands oil, combined with the energy intensive extraction can be achieved by maximizing efficiency not maximizing Big Oil's profits. Extracting oil from U.S. public lands through oil shale or tar sands would deal a Fuel efficiency, public transit, better urban planning, and a new generation of 24 Feb 2020 Bitumen from the Alberta oilsands is extracted using steam assisted Yes, the oilsands have become more efficient at producing usable crude In 2006 approved oil sands mining projects were licensed to divert 370 million sweep efficiency: The volume of reservoir that is contacted during extraction. have investigated how the bitumen can be recovered from the oil sands economically and efficiently. Several bitumen extraction processes have been
