(Hong Kong, August 30, 2004) - CNOOC Limited (the "Company", NYSE: CEO, SEHK:
883) announced today that it had completed the drilling of Weizhou (WZ) 11-1N-2,

With a total depth of 2,272 meters, WZ11-1N-2 is located about 44 kilometers
southwest of the Weizhou Island and approximately three kilometers northwest of
WZ11-1. The well was drilled on the WZ11-1N structure with water depth at 40
meters. WZ11-1N-2 was tested to flow over 3,000 barrels of oil and 340 thousand
cubic feet of gas per day on 17.46 mm choke during the drill stem test.

Mr. Zhang Guohua, Senior Vice President of the Company, commented, "WZ11-1N's
proximity to WZ11-1 makes it a very attractive discovery."

The Company is the operator and owns a 100 percent interest in the WZ11-1N
discovery.
