Dave that O(16mbpd) of new capacity is stuff that will have first oil by 2010 - lots of it will not have reached plateau by then.  You can probably roughly approximate it as a wedge from zero at the beginning of 05 to 16mbpd at about the end of 2012 - that won't be too far wrong.
I take your point.

For new production 2006 to 2010, out of convenience, I simply took Skrebowski' mbd numbers for each year from the Megaprojects document (e.g. 3.1/mbd in 2006), multiplied them out over the year and added each year together. Then I just doubled the total for new natural gas production boe. That's how I got the number and I'm sure it is a generous estimate.
