Canadian oil sands produce about 1.2 million barrels a day, or about 9 percent of the imported oil consumed in the United States. Production was headed toward 3.5 million barrels a day by 2015 before the economic slowdown; with the vast reserves available, Canadian oil sands have the potential to produce the equivalent of 1.7 trillion barrels of oil. The oil sands companies, however, have been scaling back as falling oil prices and the general market turmoil create a significant economic challenge for the projects. The entire process adds up to the worldâs most capital-intensive method for extracting oil. A tiny example: each of the tires on the cartoonishly oversized dump trucks used in oil sands mining costs about $60,000." Tire change for 60K? No problemo!
