Biggest Oil Company In The World

Bet you didn't know that Saudi Aramco (the state-owned oil company of Saudi Arabia) was the biggest oil company in the world (public or private)!  Apparently they have an estimated market cap of $10T or about 15x the size of Apple!!  Their biggest oil field also produces around 5MM barrels of oil per day and the company as a whole makes more then $1B per day in revenues.
