"..Saudi reserves are not as bountiful as sometimes described .."

Sadad al-Husseini, a geologist and former head of exploration at the Saudi Arabian oil monopoly Aramco, has warned that his country may have far less oil than experts previously thought. Also, the U.S. consul in Saudi Arabia has warned America that it should take that warning seriously. Those warnings were revealed when secret cables were released by WikiLeaks to the London Guardian newspaper.
"According to al-Husseini, the crux of the issue is twofold," the text of one cable read. "First, it is possible that Saudi reserves are not as bountiful as sometimes described, and the timeline for their production not as unrestrained as Aramco and energy optimists would like to portray." Other experts agree with al-Husseini's warning.
