Peak Oil as a Function of Earth's Volume [View article]
There is absolutely no chance of petroleum below a few miles down because the temperature is too high for the hydrocarbons to be stable. Petroleum cannot exist within molten rock! So it is a complete non sequitur to quote the total volume of the earth as potentially containing petroleum. The volume of the crust is a more relevant metric.
Having said that, the main problem with the location and exploitation of fossil fuel reserves (and other energy sources) is political, not technical. Removal of government restrictions would vastly increase available sources of energy from coal to petroleum to nuclear. (And the alternative energy sources would have to sink or swim on their own merits rather than surviving only because of massive government subsidies.)
