� Water depth around 2,200m (7,218ft)

� Environmental conditions worse than Campos Basin

� High CO2 and H2S content

� High Pressures (higher than Campos Basin fields)

� 300km from the coast

� Deep reservoirs (5,000m to 7,000m)

� High GOR ratio

� Flow assurance constraints (low temperatures & potential wax deposition)

Pre-salt Challenges

Pre-salt Challenges for Subsea Equipment

� Premises for up to 25% of CO2 and 200 ppmv of H2S

� Qualification of flexible risers for 2,200m WD considering CO2 & high pressures

� Qualification of flexible flowlines for high pressure gas injection (8,000psi)

� Coupled and uncoupled riser configurations

� Inspection and monitoring of subsea risers, flowlines and export pipelines

� Installation, operation and monitoring of uncoupled rigid risers

� Temperature management along the subsea lines

� Operation of water-alternated-gas (WAG) injection


Flexible Risers Steel Rigid Risers

Decoupled Hybrid Risers

Riser and Pipeline Alternatives


High GOR fields;

Long step out wells/fields;

Increase oil field ultimate recovery;

Development of compact subsea process equipment;

Simplified process plants in offshore production units – replace FPU´s;

Subsea to beach….or subsea to somewhere;

Enabler for brownfield and greenfield applications.

Subsea Processing Systems

MOTIVATIONS:


ESP in a dummy well (MOBO): Jubarte and Golfinho fields

Petrobras Subsea Processing

and Boosting Examples

ESP in a mudline skid (S-BCSS):

Espadarte (Brazil) and Cascade & Chinook (US) fields

Gas-Liquid Separation (VASPS):

Marimba field

Multiphase Pumps: Marlim and Barracuda fields

Raw Water Injection: Albacora field

Oil-Water Separation (SSAO): Marlim field

Subsea Electrical

Power Distribution

• Reduce FPU areas needed for Variable Frequency Drives (VFD) and power umbilicals;

• Power umbilical optimization (less total length & installation costs);

• Keen interest in:

Short term: Pressure compensated equipment (less weight) for 3 MW loads;

Long term: DC power transmission (real enabler for very long step outs);


Subsea Equipment

Integrity Management

Extending the life of mature fields populated with ageing equipment presents one of the biggest challenges for global subsea E&P in the 21st Century:

e.g.: Options that may be considered for subsea trees, manifolds and their control systems:

� Replace life expired equipment with a new one, or ...

� Retrieve, refurbish & reinstall, or ...

� Inspect, evaluate life extension and replace if necessary

The increased need for integrity management techniques and services offers extensive possibilities for partnerships with local companies, typically for:

� Inspection equipment (e.g. AUVs)

� Operational life extension evaluation

� Repair tools


Opportunities in Brazil for

Subsea Equipment Suppliers


Joint Development of an Innovative Concept: Shared Actuator Manifold

Outstanding Example of Cooperation

Between Brazil and UK Companies

• Subsea Manifold with “manual” valves actuated by a shared actuator (robotic) control system

• Shared Actuator System: Petrobras Concept developed by Subsea Offshore in UK and the former Consub (now Subsea 7) in Brazil

• Ten years of continuous operation without any production loss failure. Regarded as one of “The Best” subsea manifolds in Campos Basin

Robotic Tool: “Walk Actuator”


Conclusion: Petrobras Production Systems
