The USA is still in the grip of one of its biggest oil booms in generations and is one of the top producers in the world with more than 11 million barrels of oil a day. That boom is driven in large part by soaring extractions in Texas: the Permian Basin in West Texas and the Eagle Ford formation in South Texas. Texas production topped 3 million barrels a day this year for the first time since the late 1970s, according to the Energy Information Administration.
