                   CNOOC and BG Join Hands in Offshore China

(Hong Kong, June 7, 2006) - CNOOC Limited (NYSE: CEO, SEHK: 883, "the
Company") announced today that its parent company, China National Offshore Oil
Corporation (CNOOC) has inked two production sharing contracts (PSC) with BG
Group (BG) for deepwater blocks 64/11 and 53/16 in the Western South China
Sea. In the meantime, a Geophysical Survey Agreement (GSA) on block 41/06 in
the Eastern South China Sea has been signed between the two parties.


Both of the PSC blocks are located in the Qiong Dong Nan basin, and block
41/06 is in the Pearl River Mouth Basin. These three blocks are on the list of
12 blocks CNOOC offered for cooperation in 2002, covering a total area of
approximately 25,800 square kilometers in water depth ranging form 180 to 2100
meters.


This is the first step for CNOOC and BG to cooperate in offshore China.
Previously, four deepwater contracts have already been signed between CNOOC
and its foreign partners.


Under the terms of the contracts, BG will conduct 2D and 3D seismic in Block
64/11 and 53/16, and drill 1 exploration well during the first phase of the
exploration period on each block. BG will retain 100 percent interests during
the exploration phase and the Company has the right to participate up to 51%
working interest in any commercial discoveries in the blocks.


According to the GSA on Block 41/06, BG is committed to acquire 2D seismic
data and conduct processing and interpretation of current data.


Mr. Fu Chengyu, Chairman and CEO of the Company said, "We welcome BG's
decision to join us in exploring the deep water potential offshore China. I
expect a successful partnership, which would bring value to both companies. "
