Bob, your doing an amazing job here digging up all this stuff - heres the picture you posted. Does Lahererere indicate what the coluours mean here? I'll respond to your questions in a separate post

Any idea on the data source(s) for this impressive graphic ? Date of data ?

My guess is that this is an educated guess for today based on available information.

It may be worth noting that the most important thing I have learned so far from this extended discussion is NOT when Ghawar production will drop

A) Now
B) Very Soon
C) Soon

although that it is critically important.

The most important lesson is that it will be a very sudden and rapid collapse for each affected section, and the "at risk" sections (see multiple choice above) total an irreplacable ~4 million b/day !

Best Hopes,

Alan

Hello Euan,

Sorry, can't help with any more details on the graphic--I don't know French.

The TopToders have got to carry the ball forward. I have practically turned into a zombie trying to stay up with you guys. I have even been googling, then reading sponge coring links after F_F mentioned it---is that sick? =)
