We regularly see oil production figures of varying reliability. But a lot of energy is used by the oil industry itself. Has anyone collected figures for the amount of output sold by oil companies? is the amount of gasoline etc produced by and not consumed by oil companies been calculated?
I gather that EO/EI is a decreasing number and that oil production is at best rising slowly. Is it not possible that EO-EI is actually declining?

Despite the sloppy way people post on PO.com EROEI has to be above 1:1 for there to be any profit in the system. At below 1:1 you are putting in more energy than you are getting out and the only way that will be done is if A someone is subsidizing you to do so or B the end product is far more useful than the beginning product. Ethanol fills the A slot in the opinion of many, for B you would need to input something like Coal and electrolysis produced Hydrogen and get out Methane. You can do that with the proper equipment and the Methane can be very useful for heating or combined cycle gast turbine electric plants, but the energy of the coal and energy needed to produce the hydrogen will exceed the raw energy in the methane.
$this->bbcode_second_pass_quote('Alfred Tennyson', 'W')e are not now that strength which in old days
Moved earth and heaven, that which we are, we are;
One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.
Moved earth and heaven, that which we are, we are;
One equal temper of heroic hearts,
