                    Oil Fields CFD 11-1/11-2 Came On Stream

(Hong Kong, July 20, 2004) - CNOOC Limited (together with its subsidiaries,
the "Company", NYSE: CEO, SEHK: 883) announced today that Caofeidian ("CFD")
11-1/11-2 have come on stream successfully ahead of schedule. It is expected
that gross production of these oil fields will reach 15,000 to 20,000 barrels
of oil per day within the next several months.

CFD 11-1/11-2 are located on block 04/36 in the western part of Bohai Bay and
have a water depth of 20 meters. The oil fields are operated by Kerr-McGee,
using the Hai Yang Shi You 112, a floating production, storage and offloading
facility (FPSO), as the main production platform. The FPSO can process up to
80,000 barrels of oil and 350,000 barrels of gross liquids a day. It can store
up to one million barrels of oil for offloading to shuttle tankers. The first
phase of the development of CFD 11-1/11-2 includes one 48-slot wellhead
gathering platform and one 24-slot wellhead platform.

The Company expects CFD 11-1/11-2 to reach their peak production by mid-2005,
producing 40,000 to 45,000 barrels of oil per day.

Mr. Zhou Shouwei, President of the Company commented, "Time and again, we and
our partners prove that we can continue to deliver results, no matter how
demanding the job may be. Let me congratulate our partners for a job well
done."

The Company owns a 51% interest in the oil fields. Kerr-McGee is the operator
with a 40% interest. Sino-American Energy Corp., a subsidiary of Ultra
Petroleum, owns the remaining 9% interest.
