^^My bro is a regional executive for an oil exploration company in Egypt. I should ask him what he knows (if anything) about what the industry thinks of Saudi Arabia.
Somewhere around half of Saudi production comes from the Ghawar field. Information is tightly controlled. So far its production is holding relatively stable around 5-5.3mmbpd. But there isn't any independent corroboration. Apparently the water cut has increased from 28% to 38%, based on possible faulty information. That could be an early indication of falling off the production plateau.
Pretty much impossible to get the full story.
