U.S. oil production grew more in 2012 than in any year in the history of domestic oil production which began back in 1859. Daily crude output averaged 6.4 million barrels a day hitting a 15 year high. The U.S. Energy Information Administration expects 2013 will be even greater with daily production expected to increase almost 1 million barrels a day. With the sluggish economy and fuel economy of vehicles increasing, oil demand fell to a 16 year low in 2012. Total oil imports to the U.S. also fell by 6.9% to a 15 year low. In a related development, ExxonMobil predicts that North America will become a net exporter of all energy by 2025 due to energy development in the U.S. and Canada.
