Oil Gravity Profile
Main Offshore Production Locations
• Reservoir Characteristics• Mild Environmental Conditions• Early Production Unit as a Field-scale
Lab for Definitive Systems• Extended Well Testing & Phased
Development• Lower Capital Exposure & Early Cash
Flow• Anticipation of First Oil & High Level of
Flexibility• Field-proven & Reliable Technology• Partnerships with the Main Suppliers

Production and Target
Conclusion
• Technology development provides importanttools to face the challenging scenario ofdeepwater oil production
• Equipment are available, but to be able tospecify and correctly use them is an importantlesson from the experience
• Field development in phases allow moreflexibility and the use of information fromprevious phases on calibration of the next ones
