According to Petroleum Economist, "Although tar sands occur in more than 70 countries, the bulk is found in Canada in four regions: Athabasca, Wabasca, Cold Lake, Peace River; together covering an area of some 77,000 km2".(1) In fact, the reserve considered to be technically recoverable is estimated at 280-300 Gb (billions of barrels), larger than the Saudi Arabia oil reserves [optimistically] estimated at 240 Gb. The total reserves for Alberta, including oil not recoverable using current technology, are estimated at 1,700-2,500 Gb.
Alberta's oil sands comprise one of the world's two largest sources of bitumen; the other is in Venezuela.

"Bitumen makes up about 10-12 per cent of the actual oil sands found in Alberta. The remainder is 80-85 per cent mineral matter - including sand and clays - and 4-6 per cent water."In other words, Alberta is fast creating an environmental disaster with the 88+% of water and minerals being exposed to the biosphere in the refining process.
Canada Pays Environmentally for U.S. Oil Thirst, Huge Mines Rapidly Draining Rivers, Cutting Into Forests, Boosting Emissions, by Doug Struck, Washington Post Foreign Service, Page A01 [2006 May 31]
"FORT MCMURRAY, Alberta -- Huge mines here turning tarry sand into cash for Canada and oil for the United States are taking an unexpectedly high environmental toll, sucking water from rivers and natural gas from wells and producing large amounts of gases linked to global warming.

"The primary purpose of the report is to provide an objective assessment of the current state of the oil sands industry and of the potential for growth. In addition, it identifies and discusses the major issues and challenges associated with further development and, in this regard, the report is intended to further the public dialogue."
The end of the oil age, by Richard Heinberg [2003 Fall]
" Oil sands are likewise reputed to be potential substitutes for conventional oil. The Athabasca oil sands in northern Alberta contain an estimated 870 billion to 1.3 trillion barrels of oil -- an amount equal to or greater than all of the conventional oil extracted to date. Currently, Syncrude (a consortium of companies) and Suncor (a division of Sun Oil Company) operate oil sands plants in Alberta. Syncrude now produces over 200,000 barrels of oil a day. The extraction process involves using hot-water flotation to remove a thin coating of oil from grains of sand, then adding naphtha to the resulting tar-like material to thin it so that it can be pumped. Currently, two tons of sand must be mined in order to yield one barrel of oil. As with oil shale, the net-energy figures for oil sands are discouraging. Geologist Walter Youngquist notes "it takes the equivalent of two out of each three barrels of oil recovered to pay for all the energy and other costs involved in getting the oil from the oil sands.See also Oil Shale.
