Company Press Release

CNOOC Signed Supplemental Development Agreement

(Hong Kong, September 6, 2002) - CNOOC Limited (the "Company", SEHK: 883;
NYSE: CEO) announced today that its parent company, China National Offshore
Oil Corporation ("CNOOC") had signed a supplemental development agreement
regarding the CFD 11-1/11-2 oil fields in 04/36 Block in Bohai Bay, with
Kerr-McGee China Petroleum Limited, a subsidiary of Kerr-McGee Corp. (NYSE:
KMG) and Sino-American Energy Corp., a wholly owned subsidiary of Ultra
Petroleum Corp. (AMEX: UPL). The agreement marks concurrence on major issues
of the oilfield development among the parties.

The CFD 11-1/11-2 oil fields are about 90 kilometers offshore southeast of
Tanggu. The contract covers an area of 91 square kilometers. These two oil
fields were discovered at the end of 1999 and in the middle of 2001,
respectively. Under the agreement, the Company and its partners will draw up an
overall development plan for the development of these two fields.

The CFD 11-1/11-2 oil fields will be developed in two phases. The first phase of
the project, consisting of a central platform, one wellhead platform, a single
point mooring system and an FPSO unit, is expected to come on-line in the second
half of 2004. The second phase will include an additional wellhead platform.

Subject to final government approval, the Company will have a 51% working
interest in these two oil fields. Kerr-McGee, as the operator, will have a 40.1%
working interest and Sino-American Energy will have an 8.9% working interest.

"The discovery and development of the CFD11-1/11-2 oil fields is the result of
the mutual cooperation between the Company and its partners. It also
demonstrates the exploration and development potential in Bohai Bay," commented
Mr. Zhou Shouwei, President and Executive Director of the Company. "The Bohai
area is the focus of our exploration and development program and a major part of
our production growth."
