Testing Hubbert
نویسنده
چکیده
The Hubbert theory of oil depletion, which states that oil production in large regions follows a bell-shaped curve over time, has been cited as a method to predict the future of global oil production. However, the assumptions of the Hubbert method have never been rigourously tested with a large dataset. In this paper, the Hubbert theory of depletion is tested against five alternative models, using a set of 139 oil production curves. These curves are sub-national (United States state-level, United States regional-level), national, and multinational (subcontinental and continental) in scale. Best-fitting curves are generated for each region using the six models, and the quality of fit is compared across models. We also test two assertions that have been made with respect to oil depletion: that production over time in a region tends to be symmetric, and that production is more bell-shaped in larger regions than in smaller regions. ∗I would like to gratefully acknowledge the assistance of Anand Patil, Alex Farrell, and Jim Kirchner in the preparation and revision of this paper.

A Study on Hubbert Peak for Natural Gas of Bangladesh: A System Dynamics Approach
M. King Hubbert, an American geophysicist, in 1956 introduced a logistic equation for the estimation of USA peak and lifetime. As a case study, this paper investigates the Hubbert peak for Natural Gas production of Bangladesh. In this work, the authors have adopted system dynamics methodology to examine the Hubbert peak for Bangladesh's Gas production. Results show that the peak will occur in t...
متن کاملNorth American Natural Gas Supply Forecast: The Hubbert Method Including the Effects of Institutions
In this article, the U.S. and southern Canadian natural gas supply market is considered. An important model for oil and natural gas supply is the Hubbert curve. Not all regions of the world are producing oil or natural gas following a Hubbert curve, even when price and market conditions are accounted for. One reason is that institutions are affecting supply. We investigate the possible effects ...
متن کاملEnergy Prices and Resource Depletion: Lessons from the Case of Whaling in the Nineteenth Century
The Hubbert model assumes that the worldwide production of crude oil will follow a bell-shaped curve. Oil prices are expected to increase, or even to spike up, at or after the production peak. However, the Hubbert model provides no description of price trends. We also lack historical data that can be used as a guide, since so far there have been no cases of a complete, worldwide depletion of a ...
