I voted for two. I'm not a cornucopian but I've come to believe that oil won't peak untill around 2015 or maybe later. First, the famous megaprojects report at
ODAC. It states that despite the lack of megaprojects due to come online in 2008/9/10 there are enough known potential developments to plug the gap. This suggests that the lack of scheduled projects is not for geological reasons. According to the report there is a 5.2 billion barrel field in Siberia, 2.5-3.5 billion barrel field in Iran, and many others not yet scheduled. Perhaps they are not needed? This report only considers takes into account megafields with hundreds of millions of barrels. According to the ASPO feburary 2005 newsletter, less than half the oil in 2004 was found in fields of over 100 million barrels. This ratio has probably been similar over the last 10 years or so. If this is true then the production from many smaller fields should at least equal the production from the fewer large fields. OPEC seems to intend on keeping oil in the $40-50 region, this should put the brakes on growth somewhat and ensure that the more expensive projects (Caspian Sea) are fasttracked.
Also read this report posted on the front page today:

$this->bbcode_second_pass_quote('', 'W')orld oil production capacity could jump by more than 16 million b/d to 101.5 million b/d by 2010, with the addition split "fairly evenly" between members of the Organization of Petroleum Exporting Countries and non-OPEC producers, said an executive of Cambridge Energy Research Associates, a subsidiary of IHS Inc.
In a Feb. 15 briefing at the weeklong CERA executive conference in Houston, Peter Jackson, director of oil industry activity, said 7.6 million b/d of the projected increased total liquids production capacity would be from non-OPEC producers, with OPEC supplying 8.9 million b/d. World production of crude liquids is not expected to peak before 2020, he said.
Campbell has been wrong before and will probably be wrong again. I often find that when I use an older peak oil article to introduce a newbie to the subject there will be a graph from Campbell/Laherrere showing something going into decline that hasn't actually happened yet etc. Even after he switched to using the private database.
