Oil reserves in Saudi Arabia

"No one can set the price of oil. It's up to Allah," said Saudi Arabian Oil Minister Ali al-Naimi in May. But less devout people believe that Saudi Arabia has been trying very hard to set the price of oil - and to set it low. Moreover, it has been remarkably successful, because last week the price of oil was in the mid $40s per barrel, down from just over $100 last May.
