I note that the price to recover oil in Saudi Arabia and Iraq is between $2 and $3 a barrel if memory serves.

I think that's a bit on the low end, if my memory serves me that would be the cost to lift the oil, then there are additional costs to actually get the oil anywhere

Improving the effeciency and cost of current technologies that utilize oil will tend to reduce the demand for oil due to less consumption.

Do you have any proof of this? Because everything I've read on the issue has stated otherwise. The whole Jevons "paradox " thing. The more efficient we become in using a certain energy source the more of it we use.
