America’s public lands and Federal waters provide resources that are critical to the nation’s energy security. To encourage robust exploration and development of the nation’s resources, the Administration has offered millions of acres of public land and Federal waters for oil and gas leasing over the last two years. Oil production from the Outer Continental Shelf increased more than a third – from 446 million barrels in 2008 to more than 600 million barrels of estimated production in 2010. Responsible oil production from onshore public lands also increased over the past year – from 109 million barrels.
