FOR IMMEDIATE RELEASE

CNOOC MADE SIGNIFICANT NATURAL GAS DISCOVERIES IN EASTERN SOUTH CHINA SEA

(Hong Kong, July 28, 2003) CNOOC Limited (the "Company"; NYSE: CEO, SEHK: 883)
announced today that the Company made significant natural gas discoveries in
Eastern South China Sea. The preliminary appraisal results of Panyu 30-1 and
Panyu 34-1 discoveries made late last year have confirmed and delineated the
scope for recovery of natural gas reserves.

Total natural gas reserves in place from these fields are estimated to be
approximately 1.5 trillion cubic feet. "It represents the first major natural
gas discovery in the Pearl River Mouth of South China Sea, which opens new
exploration prospects in the area," commented Mr. Zhou Shouwei, president of
CNOOC Limited.

"These new discoveries will provide reliable and increased natural gas
supplies to a region with significant gas demand. The future gas supply will
help fuel the local economic growth and create a cleaner environment. They
will enhance the dominant gas supply business CNOOC has been developing,"
commented Mr. Wei Liucheng, Chairman and CEO of CNOOC Limited, "Natural gas
business is a new and increasingly visible growth engine for cash flow and
earnings of CNOOC Limited."

The preliminary development plan calls for an integrated design to add
productions from smaller reserves in the area to capture further economics. It
is targeting the fast growing Guangdong market. The initial capital
expenditure is estimated around US$500 million.

CNOOC Limited owns 100% of both Panyu 30-1 and Panyu 34-1.
