PRESS RELEASE

    CNOOC Limited Successfully Commenced Its Largest Independent Gas Field

(Hong Kong, September 23, 2003) CNOOC Limited (the "Company"; NYSE: CEO, SEHK:
883) today announced the successful commencement of Dongfang (DF) 1-1 Phase I,
the Company's largest independent gas field.

About 110 kilometers offshore from Dongfang City of Hainan Province, DF 1-1
field is located in Yinggehai of Beibu Gulf in the Western South China Sea.
The average water depth is about 70 meters.

DF1-1 is scheduled to be developed in two phases. Phase I consists of a
central platform, a production platform and an onshore processing terminal.
With 12 production wells, the designed production capacity of Phase I is about
154.8 million cubic feet per day. Phase II, however, is expected to increase
the production capacity of the field to 232 million cubic feet per day upon
its completion. Phase II development is currently subject to acceleration and
is expected to be completed in 2006, rather than 2008 as originally
contemplated.

Natural gas from DF 1-1 Phase I will be piped to Hainan Province for customers
including fertilizer plant, power plant and city gas.

Mr. Wei Liucheng, Chairman and CEO of CNOOC Limited commented, "The startup of
gas field DF1-1 represents another milestone in the successful execution of
our gas strategy. The field will provide feedstock and clean energy to Hainan
while adding production and cash flow to shareholders."

"It's a positive development for the Company. It helps us make up production
shortfall from the other gas field we own," commented Mr. Zhou Shouwei,
President of the Company.

CNOOC Limited is the operator and has a 100% interest in the field.
