If you think that some magic price point suddenly makes things better then you don't understand the EROEI cliff.

I'm not sure I understand. By EROEI cliff do you mean that below some figure greater than one, profit disappears because expense of production rises so high that no price can be had that will make it profitable? If you mean that, then it's almost a tautology. It is true that ultimately oil and NG will, at some point, remain in the ground because there will no longer be an economy or society that can afford to lift it. But are we there yet?

If the EROI is less than one and you use natural gas to produce natural gas you have to buy more gas than you sell.
