Cutler Cleveland of Boston University has reported that the EROI of oil and gas extraction in the U.S. has decreased from 100:1 in the 1930’s to 30:1 in the 1970’s to roughly 11:1 as of 2000 (Figure 1). But beyond the fact that society receives currently around 11 barrels of oil for every 1 barrel that it spends getting that oil, What does this mean?

In this post last month, I described how the recent storage build might serve as a good proxy for describing a well supplied oil market. I also presented data suggesting that actual physical oil consumption may have been running 2 - 3 Mb/d beneath supplies.

In this post, I will present further evidence that oil markets have for some time been well supplied. Furthermore, it appears to me that both the run up last summer and the more recent run up in oil prices bear the hallmarks of an oil market now being heavily influenced by speculative forces.

As a result of these forces, I believe that there is a substantial chance that oil prices may again experience a rapid drop to perhaps as low as $30 barrel before Christmas. One reason I believe this is likely is based on my research with respect to US Oil Fund USO. In February USO held 100 000 WTI contracts (1 contract = 1 000 bbls), but this had dropped to 50 000 WTI contracts recently, as ETF purchasers increasingly switched to Natural Gas. Strange as it may seem, the sale of these USO contracts may be part of what is holding WTI prices up, and natural gas prices down. As the number of WTI contracts reaches a minimum, this influence may turn around the other way.

This post is a summary of a conference call for bloggers hosted by the American Petroleum Institute (API) on Friday, May 15th, 2009, from 12 to 1 pm. The conference call was set up as a Q & A session where questions from numerous bloggers were fielded by Robert Ryan, the Vice President of Global Exploration at Chevron. Other participants that fielded some questions were Justin Higgs, News Media Advisor (Chevron), Mark Kibbe, Federal Relations Director (API), and John Felmy, Chief Economist (API). The following is an abridged version of the transcript, focusing on some of the more interesting questions and answers. A complete transcript of the conference call and recording of the call can be found here.
