Don't get used to cheap oil, analysts say
Some analysts say oil could eventually eclipse $150 a barrel, maybe even on its way to $200. In such a scenario, gasoline would easily cost more than the record high of $4.11 a gallon set last summer. Oil trades at about $50 today.
No one knows for sure, but some analysts say the spike could happen as soon as next year, perhaps in 2011 or 2012.

"I think those supply limits will come back to bite with a vengeance," said Sean Brodrick, a natural resources analyst at Weiss Research Inc.

"Demand will start growing, supply will start coming down, and you'll have that intersect again where prices will take off dramatically," Vincent said. "(But) it's not healthy for the economy. It's not healthy for the industry."
