'..the Bakken formation, one of the main drivers of shale oil output, remains commercially viable at or below $42..'<blockquote>'Only about 4 percent of U.S. shale output needs $80 a barrel or more to be profitable, according to the International Energy Agency. Most production in the Bakken formation, one of the main drivers of shale oil output, remains commercially viable at or below $42, the Paris-based International Energy Agency estimates. It expects U.S. supply to rise by almost 1 million barrels a day next year, with increasing flows to international markets.'
