Company Press Release

                CNOOC Limited Made Record Interim Results Again

      (Hong Kong, August 29, 2006) CNOOC Limited (the "Company" or "CNOOC
Ltd."; NYSE "CEO", SEHK "883") announced today, its financial and operating
results in the first half of 2006 hit the highest record since its listing,
with total revenues, net profits and net production all increased steadily.
The total revenue of the Company amounted to RMB 48.34 billion, a year on year
(yoy) increase of 47.2%. The net profit reached RMB 16.28 billion, a yoy
increase of 37.6%, and net oil and gas production 81.7 million BOE, a yoy
increase of 7.4%.

      For the first half of 2006, the Company has generated RMB 35.48 billion
from oil and gas sales, representing an increase of 43.4% over the same period
last year. The stable growth of oil and gas production, together with rise in
average realized oil prices, are the main driving forces for the notable
increase in revenue from oil and gas sales. Our average realized oil price
reached US$62.39 per barrel, up 42.1% from the same period last year.

      Meanwhile, the Company produced 68.3 million barrels of crude oil and
77.6 billion cubic feet of natural gas. The net oil and gas production from
offshore China was 74.4 million BOE, up 7.2% from the same period last year.

      Mr. Fu Chengyu, Chairman and Chief Executive Officer of the Company,
commented " Benefiting from favorable external operating environment, as well
as our solid and healthy operational performance, we have achieved exciting
operating results in the first half of this year."

      In the past six months, all of our operations proceeded smoothly. As of
June 30 2006, we have made 6 new oil and gas discoveries and appraised 2
structures successfully. Moreover, 4 oil and gas projects have commenced
production as scheduled.

      Meanwhile, our natural gas business made encouraging progress. Our
partner, Husky, has made the first deepwater gas discovery, Liwan 3-1, in
South China Sea. In addition, the first shipment of liquefied natural gas from
the Australian Northwest Shelf gas project successfully arrived at Guangdong
LNG terminal.

      We have also achieved new breakthroughs in our overseas business
development. In the first half, we completed the acquisition of a 45% interest
in Nigerian OML 130 block, and further extended our exploration activities to
Equatorial Guinea, Australia, Kenya, etc.

      Our earnings per share in the first half of 2006 are RMB 0.39. The board
of directors has approved the payment of an interim dividend of HK$ 0.12 per
share, to share the stable growth of the Company with our shareholders.

                                     -End-
