According to the Energy Information Association, the US consumes over 20 million barrels/day, which means this whopping 4.3 billion barrels in the Barrak formation equates to barely half a year’s worth of oil for the US, and the 10.3 billion barrels in the Alaska Wildlife Refuge is just a little over a year’s supply.
