The book Plan B 3.0 goes into great detail to emphasize the coming decline of oil:

“discoveries of conventional oil total roughly 2 trillion barrels, of which 1 trillion barrels have been extracted so far”

“The whole world has now been seismically searched and picked over,’ says independent geologist Colin Campbell ‘Geological knowledge has improved enormously in the past 30 years and it is almost inconceivable now that major fields remain to be found.”

But this is just a myth according to Richard Pike, chief executive of the Royal Society of Chemistry. The oil companies have just not disclosed how much is really available.

“the published estimates of proven global reserves are less than half the true amount”
