BHP BILLITON TO DEVELOP SHENZI OIL AND GAS FIELD IN GULF OF MEXICO              
BHP Billiton today announced that the Shenzi oil and gas field in the deepwater 
Gulf of Mexico has been approved for development.  The Shenzi facility will have
a design capacity to produce up to 100,000 barrels of oil and 50 million cubic  
feet of gas per day.  BHP Billiton is the operator of the field and has a 44 per
cent interest in the project.  The other co-venturers in the project are BP (28 
per cent) and Hess Corporation (28 per cent).                                   
The Shenzi field is located in the deepwater Gulf of Mexico approximately 120   
miles from the coast of Louisiana.  The field comprises Green Canyon Blocks 609,
610, 653, and 654, and water depths are approximately 4,300 feet.  The initial  
field development will consist of seven producing wells, and the full field     
development is expected to have up to 15 producing wells and possible water     
injection.  Gross costs for the full field development through 2015 are         
estimated at approximately US$4.4 billion (BHP Billiton share is US$1.94        
billion).  Recoverable reserves in the portion of the field covered by this     
approved expenditure will be assessed further during development drilling, but  
are currently estimated to be 350 - 400 million boe.  Additional potential      
reserves will be targeted for follow-up development.                            
"Shenzi will be BHP Billiton"s second operated, deepwater standalone facility in
the Gulf of Mexico," explained J. Michael Yeager, Group President Energy for BHP
Billiton.  "This project further demonstrates our transition to becoming a      
significant operator and producer in the deepwater Gulf of Mexico.  Shenzi joins
the development of the Neptune field as a BHP Billiton operated project, and    
together with our interests in Atlantis and Mad Dog, significantly expands our  
production base in the region."                                                 
A standalone, tension leg platform (TLP) has been selected for the production   
facility.  The proposed facilities, wells, and completions are proven designs   
that have been successfully implemented in the deepwater Gulf of Mexico.  All   
major contracts are in place to commence project execution.                     
First oil is expected by mid-year 2009 with seven initial pre-drilled subsea    
production wells being tied back to the TLP.  Shenzi oil will be exported via a 
new-build pipeline to Ship Shoal 332, with the gas going via a new-build lateral
into a connection in the Cleopatra trunk lines, then on to Ship Shoal 332.
