Wow - estimates of Saudi oil reserves are all over the place. Hard to know who's zoomin' whom. All things considered, this sounds more like a 'production capacity' issue than a 'proven reserves' issue. For now.

"Nevertheless, Saudi Aramco’s repeated statement about remaining recoverable oil reserves being 260 billion barrels (Gb) is still generally accepted." Interesting chart in there too showing the water content of Saudi oil rising since the 1940's. Makes one wonder how much of the reserves are actually capable of ignition!
