When will oil, natural gas, and coal peak?
In this paper, a predictive model based on a variant of the multi-cyclic Hubbert approach is applied toforecast future trend in world fossil fuel production.Starting from historical data on oil (crude and NGL), natural gas, and coal production, and taking intoconsideration three possible scenarios for the global Ultimate (i.e. cumulative production plus remainingreserves plus undiscovered […]
A variant of the Hubbert curve for world oil production forecasts
In this paper, a model that attempts to contribute in this regard is presented; it is based on a variantof the well-known Hubbert curve. In addition, the sum of multiple-Hubbert curves (two cycles) is usedto provide a better fit for the historical data on oil production (crude and natural gas liquid (NGL)).
