If Stuart's analysis is correct, it seems very likely that production from the northern part of Ghawar must have already entered a period of sharp and irreversible decline, which would account for the otherwise unexplained drops in Saudi Arabian oil production over the last two years.
The Saudis have been deliberately concealing the data that could settle this speculation quite conclusively. And yet, accurate information about what is ahead is absolutely vital in order to help us all make the adjustments and adaptations necessary for what is to come.
After Stuart's monumental research, I really think the burden of proof is on those who claim that Saudi Arabian production can continue to increase. At this point, we need not the conclusions of experts nor the reassurances from Aramco, but hard data to support the claims.
If Saudi production is permanently on the way down, we have just entered a new phase of history.
