The Largest Offshore China Oilfield Start Production

(Hong Kong, December 31, 2002) - CNOOC Limited (the "Company", SEHK: 883;
NYSE: CEO) announced today that the largest offshore oilfield, Penglai 19-3,
began to pump oil. The first phase of Penglai 19-3 in central Bohai Bay was
scheduled to come on stream before year-end.

Penglai 19-3 field was discovered in Block 11/05. It is the largest oilfield
discovered in offshore China ever. It is estimated to hold approximately 2.6
billion barrels of oil in place with further appraisal upside. Phillips China
Inc., a prior company of ConocoPhillips, made the discovery in 1999. The
development is designed in phases. The first phase is designed to have a
maximum production capacity of 40,000 barrels of equivalent per day.

The project is a joint venture between Phillips China Inc. ("PCI"), a
ConocoPhillips company, and the Company. PCI is the operator. The Company owns
51% of participating interests in the project.

Zhou Shouwei, President of the Company commented, "We are happy to see the
first oil flowing from the field. The largest offshore oilfield is expected to
contribute cash-flow and earnings for both CNOOC Limited and ConocoPhillips in
many years to come."
