Bakken Reserve Largest Ever

The U.S. Geological Survey has called the Bakken the largest continuous oil accumulation it had ever assessed. The agency, which bases its data largely on information from oil company and state drilling records, said up to 7.4 billion barrels of oil could be recovered from the Bakken and the underlying Three Forks using current technology. http://news.yahoo.com/bakken-oil-fields-mark-billionth-164007099.html
