The purpose of this study is to evaluate energy return on investment and predict future trends of this indicator. to achieve the aims, we study and evaluate the energy return on investment trend,then predict oil and gas production by Weng model and Hubbert model under ultimate recoverable resource scenario, also predict energy return investment by Weng model with linear extrapolation. In addition to comparison predictive power of Weng and Hubbert models, we used R, Rms, Mae, Mape indicators. In study of the past trend of energy return on investment in periods of 1989-2007, we reached the conclution that at least the equivalent of 4.9 in 2002 and the maximum amount is equal to 60.2 in 2007. Hubbert production forecast model were calculated under the average scienario show the peak of crude oil and natural gas equal to 1070.17million tonnes in 2067, however the peak of them based on Weng model will be 1122.82 million tonnes in 2087. In comparing Weng and Hubbert models, we conclude that the Weng model has the better predictive power than Hubbert model.
