· Tar sands are deposits of about 90 percent sand or sandstone, ... The process uses a lot of water and energy in the form of natural gas and oil.

Alberta's tar sands alone could yield 300 billion barrels of oil using current processing methods more than the reserves of conventional oil in Saudi Arabia. It seems likely, in view of continuing requirements for oil as an energy source and raw organic material, that at least some of the decline in conventional production will be replaced by increasing production from oil sands and shales.

Tar Sands Tar sands are grains of sand or, in some cases, porous carbonate rocks that are intimately mixed with a very heavy, asphaltlike crude oil called bitumen. The bitumen is much too viscous to be recovered by traditional petroleum recovery techniques. Tar sands contain about 1015% bitumen, the remainder being sand or other inorganic ...

 · Alberta Tar Sands is a egory limited to the loion and production of tar sand bitumen, an area the size of the state of Florida in northern Alberta province. The giant processing plants near Fort McMurray where the land itself is strip mined as well as the primarily "in situ" inground steam separation/production and extraction plants in the Peace and Cold Lake Regions, all in Alberta ...

Tar sand pretreatment with diluent J. Hupka and Miller Abstract — Important aspects of kerosene penetration into tar sand have been investigated. The natural tar sand porosity was measured and used to analyze the performance of the hot water process. Subsequently, pretreatment experi­ ments, using 20kg tar sand samples (Asphalt Ridge and

Tar sands (also called oil sands) are a mixture of sand, clay, water, and bitumen.[1] Bitumen is a thick, sticky, black oil that can form naturally in a variety of ways, usually when lighter oil is degraded by bacteria.[2] Bitumen has long been used in waterproofing materials for buildings, and is most familiar today as the binding agent in road asphalt.

Tar sands, which can produce 20 percent more greenhouse gas emissions in total than even conventional oil resources, should be "one of the first fuel sources we avoid," the group wrote. And yet, even now, with an oversupply of oil and natural gas—and with the consequences of global warming increasingly glaring—it appears we simply can't help ourselves.

 · Tar sands mining in Fort McMurray, Alberta. (Source: iStock, Credit: Dan Barnes Photography) Oil sands (or tar sands as they are sometimes inaccurately referred to) represent a vast resource of recoverable oil quantities of oil sands are loed around the world, particularly in Canada, eastern Venezuela and Saudia Arabia 314 billion barrels of .

Because of fracking natural gas the main source of energy for extracting and processing tar sands may remain cheap for years to come. This cushions the cost of producing transport fuel from this low quality oil. If natural gas prices remained at levels seen in 2007/8 tar sands production and processing would be far less profitable.

The Tar Sands are one of the most environmentally and socially destructive projects on the face of the planet. From whatever way you look at them they only conclusion is that they need to be stopped. Here are just some of the issues: Tar Sands and Global Warming Tar Sands and Water Tar Sands and.

Tar Sands. Tar sands oil is the worst type of oil for the climate, producing three times the greenhouse gas emissions of conventionally produced oil because of the energy required to extract and process tar sands oil. Tar sands consist of heavy crude oil mixed with sand, clay and bitumen. Extraction entails burning natural gas to generate ...

Natural bitumen accumulations in the United States are generally known as "tar sands," a generic term that has been used for several decades to describe petroleumbearing rocks exposed on the Earth's surface (fig. 1). Other terms for such accumulations include oil sand, oilimpregnated sand, asphaltic sand, rock asphalt, bitumi

Facts about these impacts are available at Oil Sands Reality Check. Refining Tar Sands. This site focuses on the refineries that process tar sands crude in the USA and Canada. The refining of tar sands crude is a particularly intensive and polluting process and has increased dramatically in recent years.
