While out walking the other the day, I got this crazy idea that by using Google earth we could have a good look at Ghawar and see how much drilling is really going on in that part of the woods.

It may at least give us some idea as to how intensive Saudi drilling is.

Any takers?

Google Earth doesn't use anything approaching real-time satellite images. As far as I know, most of the images used are years old.
Taking a quick look at SPOT satellite image prices, it might take about $20,000 to buy current and archival images for several thousand square kilometers of the Middle East. You could compare the images taken at different times to estimate activity.
