"Don't forget about Energy Input required to achieve Energy Output. When that ratio approaches 1.0 there will be no additional oil extracted for the obvious reason that if you expend as much energy as you can recover there is zero gain for the energy and work involved. A lot of oil in the ground will never be extracted."

If the input energy comes from less costly sources the ratio could go past 1.0 and oil output could increase.

I agree with Bob, Edward, but will add another point.

Oil's appeal is as a transportation fuel, as we know.
It is energy dense, stable and easily moved around.

If the energy to produce transportation fuel from crude is 1:1, it is still a cost effective method of moving us around this planet.

Your point is well taken, but I think that your threshold number is a bit higher than 1:1.

Cheers,
S&P
