In this post, I collaborate with Matt Mushalik from Sydney, Australia. Matt is a civil engineer, town and regional planner, peak oil advisor, and member of ASPO Australia. Most of the ideas in the post are Matt's. I have added a little to the analysis, particularly in the area of the Katrina impact.

In this post, we use a graphical approach for analyzing oil production since 2001. This analysis shows that more and more countries are showing declining oil production, and that this decline in production is not being offset by increases in production elsewhere. If this pattern continues, this analysis suggests that we may already be past the peak in world oil production.

We also look at the question of whether the impact of Hurricane Katrina may have hidden the real peak in world oil production. We find that if an adjustment is made for hurricane impacts, the peak month of production seems to be December 2005 on a crude and condensate basis, and September 2005 on an all liquids basis. The higher adjusted peaks, and greater declines since the adjusted peaks, further suggest that we may be post-peak.
