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 latest list with the sources beside the field. Is this all we know?

“This order [i.e. capitalism] is now bound to the technical and economic conditions of machine production which today determine the lives of all the individuals who are born into this mechanism, not only those directly concerned with the economic acquisition, with irresistible force. Perhaps it will so determine them until the last ton of fossilized coal is burnt.”

—Max Weber, 1905
