ExxonMobil Ups Reserves 105 Percent of Production

Exxon Mobil Corporation announced today that additions to its worldwide proved oil and gas reserves totaled 1.7 billion oil-equivalent barrels in 2003, replacing 105 percent of production, including property sales.

Exxon Mobil Corporation Chairman Lee Raymond said, "This marks the tenth year in a row that proved reserves additions have more than replaced our produced volumes".

The 2003 results were led by significant reserve additions from ExxonMobil's growth areas in the Caspian Region developments including the Kashagan field and expansions to the Tengiz and Azeri-Chirag-Guneshli fields, in Qatar from ExxonMobil's participation in the development of the North Field gas resource, in West Africa from developments in Nigeria and Chad and from new developments and established operations in Europe.
