11 CO 2 Management

12 Handling of CO2 in the Pre-Salt Hydrocarbon Fluids Motivation: High (8 to 20%) CO 2 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 CO 2 associated to the produced gas. Questions raised: What is the best way to capture the CO 2 in an offshore ultra-deep water environment (2,100 m WD), 300 km from shore? What is the best option for sequestrating the captured CO 2?

17 Final Remarks

18 Final Remarks 7 production system (FPSOs) at Santos Basin; Natural gas pre-treatment and the CO 2 separation using membranes are running with success; Around 7 million tonnes of CO2 injected (December 2017); Technology is the key factor to address the changing energy environment.
