Athabasca Oil Sands and a crude oil consumption scenario

According to statistics taken in 2006, The United States consumes 20,588 barrels of crude oil per day. Send to the USA, China consumes 7,274 barrels of crude oil per day. Japan consumes 5,222, Russia consumes 3,103, Germany consumes 2,630, India consumes 2,534, Canada consumes 2,218, Brazil consumes 2,183, South Korea consumes 2,157, Saudi Arabia (OPEC) consumes 2,068, Mexico consumes 2,030, France consumes 1,972, United Kingdom consumes 1,816, Italy consumes 1,709 and Iran (OPEC) consumes 1,627 barrels of crude oil per day. Together this equals 59,131 barrels of crude oil per day.

Newly highlighted extra heavy oil resources, such as the Orinoco oil belt north of the Orinoco River in eastern Venezuela, the Athabasca Oil Sands in Alberta Canada and Utah's Tar Sand Resource, have been gaining our attention. It is estimated that he Athabasca Oil Sands in Alberta Canada, the second largest tar sand oil reserve in the world has 175 billion barrels of crude oil.

Taking into account that the US, the worlds largest consumer of crude oil, consumes approximately 20 barrels of crude oil per day, 5 days times 20 barrels of crude oil equals 100 million barrels of oil, 50 days times 20 barrels of crude oil equals 1 billion barrels of oil and 50 days times 175 billion barrels of crude oil equals 8,750 days of crude oil if we continue to use up 20 barrels of crude oil per day, 1 year equals 365.242199 days this leaves us a 23.956706 year supply of crude oil and the situation can't possibly be as bad as it seems. Granted, this scenario only takes America's oil consumption into account, but this scenario also only takes into account that the only crude oil left on the planet is located in the Athabasca Oil Sands and the also that the only source of crude oil is extra heavy oil.

Taking into account that the entire world consumes more well over 60 million barrels of crude oil (at most 100 million taking the lack of statistic stated in this article) per day, it's fair to say that we can count the amount of years we have left, but does this mean that we only have 10-15 years of fuel left?
