Chevron Granted 10-Year Production Period Extension for Concessions in the Gulf of Thailand

Milestone agreement with Thai government is a boost for future energy supplies to the country

SAN RAMON, Calif., and BANGKOK, Thailand, Oct. 29, 2007 - Chevron Corporation (NYSE: CVX) today announced that its subsidiary Chevron Thailand Exploration and Production, Ltd, its co-concessionaires and the Thai Ministry of Energy have signed an agreement to extend the production period of four offshore blocks in the Gulf of Thailand for an additional 10 years, from 2012 to 2022.

The extension of these leases in block numbers 10, 11, 12 and 13 facilitates Chevron's long-range plans to boost production from this area to more than 1 billion cubic feet of natural gas per day. The offshore blocks encompass Erawan, Satun, Funan, Banpot, Plamuk, Yala, Pla Daeng, and Platong operating areas in the Gulf of Thailand. Chevron has working interests in the operating areas within these blocks ranging from 60 percent to 80 percent.

Speaking at the signing ceremony in Bangkok today, Dave O'Reilly, Chevron's chairman and CEO said, "We extend our gratitude to the Kingdom of Thailand for its ongoing support and express our commitment to assisting with the long-term expansion of Thailand's energy resources. We consider the Gulf of Thailand to be an exploration and production focus area for the company, and we look forward to working in partnership with the Kingdom to continue to grow our activities here."

Khun Tara Tiradnakorn, president of Chevron Thailand Exploration and Production, said: "The signing of this production period extension is the first of its kind in the history of the Thai energy industry and is testimony to our long-term commitment to Thailand. As the leading producer with more than 45 years of oil and gas experience in the Gulf of Thailand, Chevron is dedicated to working with the Kingdom to meet its growing energy needs and to provide a reliable supply of energy for the future."

He added, "The development plan for this area calls for significant investments to create opportunities for further offshore development, boost recoverable reserves and production, and develop the energy resources of the Thai people to assist with long-term economic growth and prosperity."

Chevron's co-concessionaires in the blocks include Mitsui Oil Exploration Co., Ltd, and PTT Exploration and Production Public Company Limited.
