Peak oil is the theorized point in time when the maximum rate of extraction of petroleum is reached, after which it is expected to enter terminal decline.[2] Peak oil theory is based on the observed rise, peak, fall, and depletion of aggregate production rate in oil fields over time.

The concept of peak oil is often credited to geologist M. King Hubbert whose 1956 paper first presented a formal theory.
