SAN RAMON, Calif. -- October 25, 2013

Chevron Corporation (NYSE: CVX) today announced the successful conclusion of
the initial exploration phase by its Canadian subsidiary, Chevron Canada
Limited, in the Kaybob area of the Duvernay play, located in west-central
Alberta, Canada.

Chevron Canada Limited successfully concluded the initial twelve well
exploration drilling program in the liquids-rich portion of the Duvernay shale
play. Five wells have been completed and are tied into production facilities,
and an additional four wells are waiting on completion and tie-in. The
company’s acreage is well positioned in the condensate-rich and volatile-oil
portion of the play. Liquids yield for the completed wells range from 30 to 70
percent with initial production rates up to 7.5 million cubic feet of natural
gas per day and 1,300 barrels of condensate per day.

“Early results of our Duvernay exploration program are encouraging,” said
George Kirkland, vice chairman of Chevron Corporation. “This discovery creates
a foundation for future growth in Canada.”

“Well performance and condensate yields exceeded our expectation and
strengthen our plans going forward. Near term plans include transitioning to a
two-rig drilling program to optimize well and completion design, and full
field spacing requirements,” said Jeff Shellebarger, president of Chevron
North America Exploration and Production Company.

With the acquisition of Alta Energy Luxembourg S.à.r.l. and affiliates’
acreage announced earlier this year, Chevron now has approximately 325,000 net
acres in the Kaybob area of the Duvernay play.
