King Hubbert's theory, is the point in time when the maximum rate of petroleum extraction is reached, after which the rate of production is expected to enter terminal decline.

Mostly due to the development of new production techniques and the exploitation of unconventional supplies, Hubbert's original predictions for world production proved premature. Peak oil is often confused with oil depletion; peak oil is the point of maximum production, while depletion refers to a period of falling reserves and supply.Some observers, such as petroleum industry experts Kenneth S.
