I think Hawiyah NGL production was similarly affected by lower numbers in the past due to completion dates on facilities being recent. That's from memory, I can't lay hands on the link, but it should be out there.

Obviously we've been over the difficulty in getting good production numbers from these fields in the past; let alone future figures. Still, I'd bet that Shedgum will go before Uthmaniyah and old fields will be progressively shut in to yield surge capacity as newer fields come on line - putting a cap on production and confusing that graph mightily.
