             BHP BILLITON'S Typhoon OILFIELD Commences Production

                         in Deepwater Gulf of Mexico





BHP Billiton today announced the first oil and gas production from the Typhoon
                  oilfield in the deepwater Gulf of Mexico.

The field started production on July 29 2001 with gross production expected to
increase to 40,000 barrels per day of oil (bopd) and 60 million standard cubic
feet (mmscfd) of gas over the coming months, although actual oil and gas
production rates will depend on well performance. (BHP Billiton's share is
50 per cent.) The estimated commercial field life is between five to eight
years.

The Typhoon project has set a new standard for rapid development of deepwater
Gulf of Mexico fields. The project was completed in just over three years,
following its discovery in June 1998. The time from project sanction to
commissioning was approximately 18 months. Typhoon was also completed safely,
under the budgeted expenditure of US$128 million (BHP Billiton share), and on
schedule.

The Typhoon project represents BHP Billiton's first commercial development
resulting from its decision to focus exploration activities in potential high
margin areas in the deepwater Gulf of Mexico. The development delivers early
production and revenues, as well as technical expertise that is being used to
expedite the commercialisation of larger resources in the ultra-deepwater
Atwater Foldbelt.

The field is located in 640 metres of water in Green Canyon blocks 236 and
237, 160 kilometres off the coast of Louisiana. This area has been actively
explored and has established production and pipeline infrastructure. BHP
Billiton's equity share of the Typhoon development is 50 per cent with Chevron
U.S.A. Production Co. (operator) 50 per cent.

President and CEO BHP Billiton Petroleum Philip Aiken said: 'This is a
tremendous achievement and marks another important step in the delivery of our
deepwater exploration strategy. Typhoon fits well into BHP Billiton's broader
Gulf of Mexico objectives and the early cash flows generated will supplement
longer term, higher value potential activities.'

The Typhoon development consists of subsea completion and tieback of the four
existing appraisal wells to a local host facility, based on the Atlantia
SeaStar mini tension leg platform (TLP). El Paso, through its oil and gas
pipeline subsidiaries, will transport the oil and gas to local markets via
connections to local infrastructure.

The Typhoon field was granted Deepwater Royalty Relief in December 2000 by the
U.S. Minerals Management Service, which allows for royalty exemption on the
first 87.5 million barrels oil equivalent (mmboe) from the Typhoon field under
certain oil pricing market conditions.

The Typhoon facilities offer the potential to act as a production 'hub' for
the area. BHP Billiton has in excess of 30 blocks within a 40-kilometer radius
and a discovery in any of these blocks could potentially be tied back to the
Typhoon facility.

BHP Billiton has interests in existing producing assets in the Gulf of Mexico
in Green Canyon/Ewing Bank/West Cameron (FY2000 BHP production share was 4,655
bpd liquid and 40 mmscfd gas). The Company also completed the purchase of 4.95
per cent of the Chevron-operated Genesis field in January 2000. Genesis is
located in Green Canyon block 205 and is currently producing at rate of
approximately 73,000 barrels of oil equivalent per day (boepd) gross, with
approximately 3,600 boepd net to BHP Billiton.

The Atwater Foldbelt appraisal of the Mad Dog and Atlantis discoveries is
continuing as are plans for progressing BHP Billiton's exploration potential
in the Atwater Valley, Walker Ridge and Mississippi Canyon lease areas. Mad
Dog is on schedule for sanction during calendar year 2001. The Atlantis 3
appraisal well is currently being drilled and a Mad Dog 4 appraisal well is to
spud in the third quarter of 2001.
