Those high prices also spurred companies to mine the oil sands of Alberta — leading to a similar boom up in Canada.
But in 2014, oil prices have been crashing, with the price for West Texas Intermediate crude falling from $100 per barrel in July to below $70 in early December. That’s partly because there’s so much new oil coming out of the US and Canada, and partly because demand in Europe and Asia is weakening.
So now everyone’s asking: If high prices helped create the oil boom in the US and Canada, will falling prices throttle it?
