SAN RAMON, Calif. -- December 27, 2012

Chevron Corporation (NYSE: CVX) today announced further drilling success by
its Australian subsidiary in the Exmouth Plateau area of the Carnarvon Basin,
a premier hydrocarbon basin.

The Pinhoe-1 exploration discovery well encountered approximately 197 feet (60
meters) of net gas pay in the Barrow and Mungaroo Sands. Pinhoe-1 is located
in the WA-383-P permit area, located approximately 124 miles (200 kilometers)
north of Exmouth off the Western Australia coast. The well was drilled in
3,048 feet (929 meters) of water to a total depth of 13,396 feet (4,083

The Arnhem-1 exploration discovery well confirmedapproximately 149 feet (45.5
meters) of net gas pay in the upper Mungaroo Sands. Arnhem-1 is in the
WA-364-P permit area, located approximately 180 miles (290 kilometres) north
of Exmouth off the Western Australia coast. The well was drilledin 3,963 feet
(1,208 meters) of water to a total depth of 9,557 feet (2913 meters).

“Chevron Australia’s ongoing success offshore of Western Australia is a result
of our long-term commitment to exploring and developing the region. The
Carnarvon Basin is a world-class hydrocarbon basin, and these discoveries
underscore the quality of our Australian portfolio and our technical
competence,” said George Kirkland, vice chairman, Chevron Corporation.

Melody Meyer, president, Chevron Asia Pacific Exploration and Production
Company, said the two discoveries expand Chevron’s discovered gas portfolio in
Australia. Chevron has now announced a total of 19 discoveries in Australia
since mid-2009.

“These discoveries in the Exmouth area are significant as they are located
farther out from other discoveries in the greater Gorgon and Wheatstone
development in the Carnarvon basin and indicates development potential in the
broader region,” said Meyer.

Chevron Australia is the operator of both the WA-383-P and WA-364-P permit
areas and has a 50 percent interest with Shell Development (Australia) Pty Ltd
holding the remaining 50 percent.
