There are some really good fields off the coast of Africa.

However, note that when Hubbert did his model for the Lower 48, a one-third increase in his URR estimate only extended the peak date by 5 years, from 1966 to 1971.

If we date the modern oil industry in the US from the Spindletop discovery in 1901, this one-third increase in the URR estimate and the five year period of additional growth in oil production extended the modern petroleum growth phase in the Lower 48 by about 8%--70 years instead of 65 years.

I'm sure that the math is very similar for the world.

The question is when, not if, an exponential growth rate in consumption versus a finite resource base proves impossible to sustain.

How good are these West African fields? Do you have any data on them? Can we get an article? How much time would they buy us?
