Oil sands before oil extraction. Once extracted, bitumen itself is a thick, black fluid of extremely high  Oil sands operations have become significantly more energy efficient over the history of the industry. • Oil sands production is largely fueled with energy from the bitumen resource itself, making external energy returns high. • Oil sands production is still significantly less efficient than conventional oil production. Oil sands operations have become significantly more energy efficient over the history of the industry. Oil sands production is largely fueled with energy from the bitumen resource itself, making external energy returns high. Oil sands production is still significantly less efficient than conventional oil production.

Currently, 20% of oil sands reserves are accessible via mining techniques. 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.

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. There are four commercial plants producing bitumen from surface minable oil sands, using some version of the Clark Hot Water Extraction (CHWE) process, which was developed in the 1930s by Dr. K.A

Meanwhile, the location and size of Saudi's oil fields also help keep its production costs down. While it's not the cheapest in the world, as several nations have production costs around $2 per barrel, it's still a fraction of the production costs of a country like Canada, which pays $11.56 to produce a barrel of oil.

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.
