Don't know if this is what you are looking for but here is a title: Geostatistical Model for the Arab-D Reservoir, North 'Ain Dar Pilot, Ghawar Field, Saudi Arabia: An Improved Reservoir Simulation Model.

This one has lots of pretty pictures.

Sorry, I just posted the Greg Croft URL before realizing you already had it.

Hello SS,

Jean Laherrere has an excellent, next generation 3D rendering of Ghawar looking from the SW --> NE [opposite direction of garyp's post]:

This might come in handy later, maybe Jean has original software.

F_F & Euan: I am fascinated with Uthmaniyah's far eastern ridgeline. If you look at GaryP's cross-sections and compare with Ghawar Oil Sat graphic--hasn't the waterfront rolled over the crest? How is the fractional flow skewed, watercut ratio best managed, and reservoir sweep best accomplished with pressurized water going downhill? I have no idea, hope you can help SS out.

Where do garyp's slices go on the Laherrere 3D and on this Uthmaniyah Graph [scroll down inside website please]:

http://home.entouch.net/dmd/ghawar.htm

Notice this above graphic from Alexander was in 1996-- has Uthmaniyah had a lot worse waterfront problems since then? We can't see the Western side of the Eastern Crest

My guess is the thick green rollover about halfway down Uthmaniyah Eastern ridge, but on the unseen western side in the Ghawar Oil Sat is where those slices best match up--but you guys might have better ideas!

From Greg Croft website:
--------------------------------
The fact that the Ghawar oil-water contact is substantially higher on the west flank than on the east indicates a hydrodynamic gradient to the east, which may explain the much larger volume of oil in Ghawar than in Khurais.

The oil-water contact at Ghawar dips to the northeast, dipping more than 660 feet between the southwest end of Haradh and the Fazran area.
-------------------------------------

This suggests to me that Aramco should have put Uthmaniyah's water injection more heavily on the west side to drive the oil east and upcrest--they did the opposite [eastside injection wells watered over the crest in a western direction instead]. Could you explain?

Another thing from Ghawar Oil Sat graphic: why is the Southern lower half of Abqaiq orange instead of yellow--what is the significance? Major reservoir sweep problems compared to Northern lower half, which is solid yellow?

One last thing:

When I blow up the PDF of the Ghawar Oil Sat graphic with the magnifying tool to 1600%--you get much more detail--for example the Shedgum to Uthmaniyah thin connection looks all blue at normal resolution but shows green breakthrough at high magnification. Farzan is only 3 miles wide at its max [approx. 3 cells wide at 1600%]--can this be a tool to generate our own cells for our own Ghawar graphics?
