Chevron Awarded Cardon III License in Venezuela's Rafael Urdaneta Bid Round

SAN RAMON, Calif., Sep. 12, 2005 -- Chevron Corporation's (NYSE: CVX) local affiliate company in Venezuela has been awarded the exploration license for the Cardon III exploration block, located offshore western Venezuela. The Cardon III block was one of seven blocks offered by the Venezuelan Ministry of Energy and Mines in the Rafael Urdaneta bid round. The block is located in an offshore region with natural gas potential on trend to the north of the prolific Maracaibo producing region.

John Watson, president of Chevron International Exploration and Production Co., stated, "We are pleased with the results of this bid round and we look forward to starting exploration activities. The award of the Cardon III block is aligned with our company's global gas strategy to seek new opportunities that can provide gas to local or export markets." Watson also noted that the company has acquired an exploration block in each of the last three exploration bid rounds offered by Venezuela.

Ali Moshiri, president of Chevron Latin America Upstream, emphasized the possible regional implications of acquiring the new block. "The award of the Cardon III license supports our regional Caribbean gas strategy that includes gas resources in Trinidad and Tobago, Colombia, and Venezuela. We are committed to growing our business in Venezuela and developing the regional infrastructure for natural gas required for both local industrial and power demands."

Chevron previously acquired a 60 percent interest in Plataforma Deltana Block 2 and holds a 100 percent interest in Plataforma Deltana Block 3, where the company has drilled a series of successful gas exploration wells.
