See Hubbert peak theory for detail on this decline curve with regard to petroleum.

The curve is the main component of Hubbert peak theory, which has led to the rise of peak oil concerns.

Basing his calculations on the peak of oil well discovery in 1948, Hubbert used his model in 1956 to create a curve which accurately predicted that oil production in the contiguous United States would peak around 1970.

Plot of the Hubbert curve

The prototypical Hubbert curve is a probability density function of a logistic distribution curve.

The density of a Hubbert curve approaches zero more slowly than a gaussian function:

The graph of a Hubbert curve consists of three key elements:

Using the curve, Hubbert modeled the rate of petroleum production for several regions, determined by the rate of new oil well discovery, and extrapolated a world production curve.

At least one researcher has attempted to create a Hubbert curve for the whaling industry and caviar, while another applied it to cod.

A bell-shaped production curve, as originally suggested by M. King Hubbert in 1956.

Because mitigation can reduce the use of traditional petroleum sources, it can also affect the timing of peak oil and the shape of the Hubbert curve.

He made several important contributions to geology, geophysics, and petroleum geology, most notably the Hubbert curve and Hubbert peak theory ( a basic component of Peak oil ), with important political ramifications.

The Hubbert peak theory says that for any given geographical area, from an individual oil-producing region to the planet as a whole, the rate of petroleum production tends to follow a bell-shaped curve.

The theory is named after American geophysicist M. King Hubbert, who created a method of modeling the production curve given an assumed ultimate recovery volume.

Their studies use the Hubbert curve, devised by M. King Hubbert, among many other methods to which predict future oil availability.

It is a common misunderstanding to believe that ASPO and peak oil only is about the Hubbert curve.

Hubbert curves predict that the production curves of non-renewing resources approximate a bell curve.

At natural rates, oil well production curves appear similar to a bell curve, a phenomenon known as the Hubbert curve.

San Saba is the birthplace of actor Tommy Lee Jones, geologist M. King Hubbert, opera singer Thomas Stewart, and Aaron Behrens, front man for Austin-based music group Ghostland Observatory.

According to Hubbert peak theory, peak oil is the date when the peak of the world's production of conventional petroleum ( crude oil ) is reached.

The Hubbert peak theory is based on the observation that the amount of oil under the ground in any region is finite, therefore the rate of discovery which initially increases quickly must reach a maximum and decline.

Kenneth S. Deffeyes is a geologist who worked with M. King Hubbert, the creator of the Hubbert peak theory, at the Shell Oil Company research laboratory in Houston, Texas.

The most famous peak oil petrogeologist is M. King Hubbert, who predicted in 1956 that oil production would peak in the United States between 1965 and 1970.

The Hubbert peak theory, also known as peak oil, is an influential theory concerning the long-term rate of production and depletion of conventional oil and other fossil fuels.

Hubbert models have been used to predict the production trends of various resources, such as natural gas ( Hubbert's attempt in the late 1970's resulted in an inaccurate prediction that natural gas production would fall dramatically in the 1980's ), Coal, fissionable materials, Helium, transition metals ( such as copper ), and water.

After Peak Oil, according to the Hubbert Peak Theory, the rate of oil production on Earth would enter a terminal decline.

On the basis of his theory, in a paper he presented to the American Petroleum Institute in 1956, Hubbert correctly predicted that production of oil from conventional sources would peak in the continental United States around 1965-1970.

In 1956, a Shell geophysicist named M. King Hubbert accurately predicted that U. S. oil production would peak in 1970.

* Hubbert peak theory, also known as peak oil – the theory that world oil production will peak ( or has peaked ), and will then rapidly decline, with a corresponding rapid increase in prices.

In 1967-69 he headed the Academy's " Committee on Resources and Man ", whose alarming report " Resources and Man " introduced to a wider public, among other things, the work on energy-resources of his friend M. King Hubbert, and the Hubbert peak theory of Peak oil production.

The Hubbert peak theory makes predictions of production rates based on prior discovery rates and anticipated production rates.
