The author draws on information held in oil industrydatasets that are not widely available outside of the specialist literature,and describes a number of methods that have been successfully used to predictoil peaks. In contrast to the widely-held view that ‘all oil forecasts arewrong’, these methods correctly predicted the current peak in globalconventional oil production. Current oil forecasts are then compared toevaluate the expected dates for regional and global oil peaks for conven
