The former energy advisor of US President George W Bush, Matthew Simmons, predicts oil prices could reach as much as 250 US dollars per barrel over the coming years. He cited an imminent shortage of oil supply and a growing global demand, especially in China and India, for the sharp rise in oil prices.
Simmons who heads the American energy investment firm Simmons & Co, pointed also to a worldwide decline in conventional oil discoveries in new fields. He anticipated global oil output could drop from the current 75 million to 65 million barrels per day by 2012.
