ExxonMobil Adds 2 Billion boe of Total Resources in 2007

The ExxonMobil's total oil and gas resource base stands at 72 billion oil-equivalent barrels at year-end 2007.

During 2007, ExxonMobil added 2.0 billion oil-equivalent barrels of total resources, which more than replaced production. Significant resource additions were made from successful drilling programs in the United States, West Africa and the Asia Pacific region.

Overall, the resource base was reduced by 1.8 billion oil-equivalent barrels in 2007, primarily driven by the effects of the Venezuelan expropriation of 1.6 billion oil-equivalent barrels.

The Corporation's resource base of 72 billion oil-equivalent barrels includes proved and probable reserves, plus other discovered resources that are expected to be ultimately recovered.
