Pre-SaltDevelopment
Source: HAYASHI, M.Y.,“Brazilian Pre-salt Update May 2015”, presented at Citi Global Energy & Utilities Conference (http://www.investidorpetrobras.com.br/en/presentations/general-presentations)
Pre-Salt• Huge reservoirs (carbonates) of oil and natural gas (recoverable reserves of 8.3 to 12 billion BOE);• Between 5,000 and 7,000 m below sea level;• ~ 300 km off the coast;• Water depth ~ 2,000 m;• Salt layer with more than 2,000 m thick, in some areas;• Light oil (30° API), high GOR (> 200), and variable CO2 content (between 1 and 20%)

From Pos-Salt to Pre-Salt
CO2 Management
Motivation:
• High (8 to 20%) CO2 content in the gas phase in some wells;• Although it doesn't have target obligations to reduce its emissions, Brazil is
committed with climate change control;• Accordingly, Petrobras and partners in the pre-salt blocks do not consider to
vent the CO2 associated to the produced gas.
Questions raised:
• What is the best way to capture the CO2 in an offshore ultra-deep waterenvironment (2,100 m WD), 300 km from shore?
• What is the best option for sequestrating the captured CO2?
Handling of CO2 in the Pre-Salt Hydrocarbon Fluids

- Size & Footprint- Weight- Efficiency
CO2 content in the fluids address challenges:
Membranes:
- Better for medium or high CO2 content- Smaller footprint- Simple to operate and easy to maintain- Process a wide range of CO2 in the inlet stream.
Natural Gas Processing
