Peak oil analyzed with a logistic function and idealized Hubbert curve

►Global oil production data were analyzed by a simple curve fitting method. ►Best fit-curve results were obtained using two logistic functions on select data. ►A broad potential oil production peak is forecast for the years from 2004 to 2014. ►Similar results were obtained using historical data from about 10 to 30 years ago. ►Two potential oil production decline scenarios were presented and compared.
