A comparison of two typical multicyclic models used to forecast the world's conventional oil production

This paper introduces two typical multicyclic models: the Hubbert model and the Generalized Weng model. The model-solving process of the two is expounded, and it provides the basis for an empirical analysis of the world's conventional oil production. The results for both show that the world's conventional oil (crude+NGLs) production will reach its peak in 2011 with a production of 30 billion barrels (Gb). In addition, the forecasting effects of these two models, given the same URR are compared, and the intrinsic characteristics of these two models are analyzed. This demonstrates that for specific criteria the multicyclic Generalized Weng model is an improvement on the multicyclic Hubbert model. Finally, based upon the resultant forecast for the world's conventional oil, some suggestions are proposed for China's policy makers.

► Hubbert model and Generalized Weng model are introduced and compared in this article. ► We conclude each model's characteristic and scopes and conditions of applicable. ► We get the same peak production and time of world's oil by applying two models. ► Multicyclic Generalized Weng model is proven slightly better than Hubbert model.
