Reserves
Many countries in the world have large deposits of oil sands, including the United States, Russia, and various countries in the Middle East.
However, the world's largest deposits occur in two countries: Canada and Venezuela, each of which has oil sand reserves approximately equal to the world's total reserves of conventional crude oil. As a result of the development of Canadian oil sands reserves, 44% of Canadian oil production in 2007 was from oil sands, with an additional 18% being heavy crude oil, while light oil and condensate had declined to 38% of the total.[8] Because growth of oil sands production has exceeded declines in conventional crude oil production, Canada has become the largest supplier of oil and refined products to the United States, ahead of Saudi Arabia and Mexico. Venezuelan production is also very large, but due to political problems within its national oil company,[9] estimates of its production data are not reliable. Outside analysts believe Venezuela's oil production has declined in recent years,[10] though there is much debate on whether this decline is depletion-related or not.
Oil sands may represent as much as two-thirds of the world's total petroleum resource, with
at least 1.7 trillion barrels (270×10^9 m3) in the Canadian Athabasca Oil Sands and perhaps 235 billion barrels (37×10^9 m3) of extra heavy crude in the Venezuelan Orinoco oil sands.[11] Between them, the Canadian and Venezuelan deposits contain about 3.6 trillion barrels (570×10^9 m3) of oil in place,
compared to 1.75 trillion barrels (280×10^9 m3) of conventional oil worldwide, most of it in Saudi Arabia and other Middle-Eastern countries.
