Who said big oil was a dying business? Fortune has released its Global 500, their "annual ranking of the world's largest corporations," and topping the charts is Royal Dutch Shell (NYSE: RDS.A), which, much like a Mariah Carey song, bumped up into the coveted number-one slot after some time at number three. The Netherlands-based oil company trumped its U.S. rival, Exxon Mobil (NYSE: XOM) by $15 billion in sales and saw its revenue spike nearly 29% from 2007.
Speaking of Exxon, the company once again had a tiger in its tank, ranking number two in the world as oil futures bounced around in a nearly $100-dollar range, hitting $146 per barrel at its heights.
