The high oil price is leading oil companies to open up oil extracting operations in places where previously the cost of extraction has been deemed to be far too high. "There is also more money going into oil-sands operations in Alberta, Canada, home to vast reserves of a tar-like bitumen that is extracted using mining techniques. Industry officials estimate the region will yield as much as 175 billion barrels of oil, making Canada second only to Saudi Arabia in crude oil reserves."
