『Abstract
A logistic function is used to characterize peak and ultimate
production of global crude oil and petroleum-derived liquid fuels.
Annual oil production data were incrementally summed to construct
a logistic curve in its initial phase. Using a curve-fitting approach,
a population-growth logistic function was applied to complete
the cumulative production curve. The simulated curve was then
deconstructed into a set of annual oil production data producing
an “idealized” Hubbert curve. An idealized Hubbert curve (IHC)
is defined as having properties of production data resulting from
a constant growth-rate under fixed resource limits. An IHC represents
a potential production curve constructed from cumulative production
data and provides a new perspective for estimating peak production
periods and remaining resources. The IHC model data show that
idealized peak oil production occurred in 2009 at 83.2 Mb/d (30.4
Gb/y). IHC simulations of truncated historical oil production
data produced similar results and indicate that this methodology
can be useful as a prediction tool.
