Abstract: This paper applies multi-cycle Hubbert model to estimate global peak oil production.By comparing the single-cycle Hubbert prediction results,as well as a large number of authors and institutions estimate,we confirm the global oil peak time will be delayed around 2037,and peak production will be more than 42Gb.Compared with the single-cycle Hubbert model,the decline rate of post peak time in accordance with multi-cycle Hubbert model is more sharply than the growth rate before the peak,in line with historical oil production data fluctuations,but also to a certain extent overcome exaggerated future peak production,so multi-cycle Hubbert model is more valuable than single-cycle model.
