In a finding that may speed efforts to conserve oil,scientists in Kuwait predict that world conventional crude oil production will peak in 2014.This prediction is almost a decade earlier than some other predictions. Their study is in ACSEnergyFuels1.
Ibrahim Nashawi and colleagues point out that rapid growth in global oil consumption has sparked a growing interest in predicting peak oil. Peak oil is the point where oil production reaches a maximum and then declines. Scientists have developed several models to forecast this point,and some put the date at 2020 or later. One of the most famous forecast models is called the Hubbert model2.It assumes that global oil production will follow a bell shaped curve3.A related concept is that4 of Peak Oil. The term Peak Oil indicates the moment in which world wide production will peak,afterwards to start on irreversible decline.
The Hubbert model accurately predicted that oil production would peak in the United States in 1970.The model has since gained in popularity and has been used to forecast oil production worldwide.
However,recent studies show that the model is insufficient to account for5 more complex oil production cycles of some countries. Those cycles can be heavily influenced by technology changes,politics,and other factors,the scientists say.
The new study describes development of a new version of the Hubbert model that provides a more realistic and accurate oil production forecast. Using the new model,the scientists evaluated the oil production trends of 47 major oil-producing countries,which supply most of the worlds conventional crude oil6.They estimated that worldwide conventional crude oil production will peak in 2014,years earlier than anticipated. The scientists also showed that the worlds oil reserves7 are being reduced at a rate of 2.1 percent a year. The new model could help inform energy-related decisions and public policy debate,they suggest.
