The Top Twenty Fields: Are They in Decline?

Taking the lead from this thread over at peakoil.com, I thought a discussion of whether or not the top 20 fields were in decline, and then consolidating that into a reference resource would be a good idea.  Under the fold is the list they put together.
(click here to see the peakoil.com thread for the resources they have used to this point.  I will update as we make progress in the comment threads.)
