')To be fair, we don't know why production is down, but it might well have to do with relative costs vs. a major geological trend change......Perhaps (and this is just speculation based on economics, not oil production know-how), they found it cheaper to let Ghawar decline naturally in the short run and ramp up other prospects.
KSA has been extremely tight with information on their oil production. Thats why the data releases in the ARAMCO bond prospectus are so important----they provide the first independent assessment of the current status of Ghawar and other Saudi oilfields.
The revelation that Ghawar oil production is down over 20% from its peak has attracted a lot of attention. Since I am a scientist I tend to put a lot of weight on the actual data, and the data shows production has recently dropped. I find it interesting how many people don't accept that data at face value.
As far as your suggestion that Aramco might have shifted oil production elsewhere because it is cheaper for Aramco to produce oil elsewhere, I personally doubt thats the reason because Ghawar is KSA's main field and its well known that oil production at Ghawar can be done very very cheaply. In fact, for decades oil at Ghawar has been among the least expensive to produce in the entire world.
The Saudis know the geology and reservoir characteristics at Ghawar extremely well, the access is excellent and the infrastructure is already in place to do more drilling, to store the oil, and to transport it to market. Theres no evidence the Saudis have stopped or slowed the drilling they do there all the time to keep production up....but production is falling nonetheless.
Almost certainly it would be more expensive for Aramco to explore for oil in new areas, work up the data and find new fields, drill test wells in remote new areas and then develop new infrastructure to produce any oil found there, and even more new infrastructure to store the oil and more infrastructure to transport new oil to market. NOPE....IMHO its unlikely they shifted their attention away from Ghawar in order to produce oil more cheaply.... There might be a strategic or political reason for it, but it probably doesn't save them any money.
Given the fact that oilcos have a well known tendency to produce their best prospects first, in order to maximize their profits, my suspicion is production at Ghawar is dropping because some areas of the field just aren't producing much oil anymore---the water cut is getting higher and higher, to the point that its now up to 98% in at least one of the sub-fields.
CHEERS!
