　　World Crude Oil Production May Peak a Decade Earlier Than Some Predict

　　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 2023 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.

　　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.
