For the first quarter of 2006, crude oil and liquids production of CNOOC
Limited reached 383,519 barrels per day and gas production 390 million cubic
feet per day. The Company also reported net production 415,144 BOE per day for
offshore China, an 11% increase from the same period last year. Strong
production growth in Bohai Bay contributed most to the increase of the
Company`s total production offshore China. The net production in Bohai Bay
increased 23.4% for crude oil and 28.2% for natural gas.

Total unaudited revenue amounted to RMB 16.66 billion for the first quarter of

a 43.8% increase from the same period last year.

The Company also made great progresses in overseas activities. In the first
quarter, the Company acquired a 45% interest in OML 130 and a 35% interest in
OPL 229 Block in Nigeria. The above acquisitions have laid solid foundation
for the Company's medium to long term overseas growth, and indicated the

growth, CNOOC Ltd achieved a great quarter."

exploration prospect offshore China.

production targets for 2006. " Commented Mr. Zhou Shouwei, President of the
Company.
