BHP BILLITON ANNOUNCES OIL DISCOVERY WITH CHINOOK E-WELL IN DEEPWATER GULF OF   
MEXICO                                                                          
BHP Billiton today announced that it has made an oil discovery at its second    
exploratory well on the Chinook prospect in the ultra-deepwater Gulf of Mexico. 
Drilled in water depths of approximately 8,830 feet (2,684 meters), the well    
exceeded a total depth of 27,650 feet (8,406 meters), encountering a gross      
hydrocarbon column of 620 feet (188 meters) with 260 feet (79 meters) of net oil
pay.                                                                            
The Chinook discovery is located more than 300 kilometers (180 miles) from the  
Louisiana coast in Walker Ridge Block 469, approximately 30 kilometers (19      
miles) south of the previously announced Cascade discovery.                     
Steve Bell, President of Exploration and Business Development for BHP Billiton  
Petroleum, said today:  "This is a very encouraging result on a large structure.
Of course, it is early days and the result must be seen in perspective.  While  
this is the deepest penetration to date on Chinook, we must have more appraisal 
data before we can be definitive about the scale of resource. Importantly, this 
strengthens our inventory of BHP Billiton-operated discoveries in the area.     
With Shenzi, Cascade, Neptune, and Vortex, we have a full appraisal programme in
place to evaluate and, if successful, create more value by ultimately           
commercialising these hydrocarbon accumulations."                               
Drilling on Chinook-3 began January 13, 2003, using the BHP Billiton operated   
drillship C.R. Luigs.  BHP Billiton owns a 40 percent interest and is the       
designated operator of Chinook with Petrobras owning a 30 percent interest, and 
Total and Amerada Hess each holding a 15 percent interest.                      
BHP Billiton holds interests in more than 340 blocks in the Gulf of Mexico,     
where the company is actively exploring for oil and gas.  Deepwater projects    
sanctioned for development include the Atlantis and Mad Dog oil and gas fields, 
in addition to producing assets at Typhoon and Boris.  In the past year the     
company has announced discoveries at Cascade, Shenzi, and Vortex, all of which  
are located in deep- and ultra-deepwater blocks.
