              CNOOC Ltd Finds New Oil Deposit in Bohai Bay Again

(Hong Kong, March 28, 2006) - CNOOC Limited (NYSE: CEO, SEHK: 883, "the
Company") announced today that it has made a new independent discovery,
Bozhong (BZ) 28-2S in the Bohai Bay with the completion of wildcat BZ28-2S-1.

The discovery well BZ28-2S-1 is located on Structure BZ28-2S in the Yellow
River Mouth Sag of central southern Bohai Bay. The well hit its target depth
of 2,125 meters, with water depth of about 22 meters.

The drilling activities commenced in February 2006. The well penetrated oil
pay zones with total thickness of 85 meters and gas sections with total
thickness of 8 meters.

Two drill stem tests were conducted over two intervals with a combined flow
rate of about 1,900 barrels of oil and 2 million cubic feet of gas per day via
7.94mm and 12.7mm chokes, respectively. Further appraisal work will be
conducted to evaluate the commercial value of the discovery.

Mr. Zhu Weilin, Vice President of the Company and General Manager of
exploration department commented, "I am pleased to declare the exciting
progress of our exploration in the Bohai Bay. It is initially estimated that
BZ28-2S is one of the largest discoveries among those made in the Bohai Bay in
recent years."
