In the ASPO Newsletter 55 (July 2005), Dr. Campbell writes "It is significant that the first quarter production of most of the major oil companies is falling : ExxonMobil -3%; Chevron -6% ; Shell -8% ; Repsol YPF -7%., while Phillips-Conoco maintained its level with BP at least reporting a 2% increase. All the more reason that the public should heed the silent alarm sounded by the ExxonMobil report, which is more credible than other predictions for several reasons. First and foremost is that the source is ExxonMobil. No oil company, much less one with so much managerial, scientific, and engineering talent, has ever discussed peak oil production before. Given the profound implications of this forecast, it must have been published only after a thorough review."
