http://www.commondreams.org/views05/0819-26.htm With the signing of the treaty last January, and the prospect of stability for most of war-torn Sudan, new seismographic studies were undertaken by foreign oil companies in April. These studies had the effect of doubling Sudan's estimated oil reserves, bringing them to at least 563 million barrels. They could yield substantially more. Khartoum claims the amount could total as much as 5 billion barrels. That's still a pittance compared to the 674 billion barrels of proven oil reserves possessed by the six Persian Gulf countries -- Saudi Arabia, Iraq, the United Arab Emirates, Kuwait, Iran, and Qatar. The very modesty of Sudan's reserves speaks volumes to the desperation with which industrial nations are grasping for alternative sources of oil.

production unless we are sure we have increased the reserves and
this is still in the air, but it looks promising," Tom said.
He put proven reserves at 650 million to 800 million barrels,
adding one billion barrels was a reasonable future target.
