2. Peregrino – an offshore heavy
oil field with large IOR potential
• High IOR potential:
− Large in-place resources
− Low recovery vs. conventional oilfields
• Already doubled recovery factor by
implementing Statoil technology Statoil operator
Statoil partner
• Ambition to further increase recovery: Key Peregrino facts
− Further leverage our technological know-how Oil density 14º API
Oil in place 2,3 billion barrels
− Evaluate Enhanced Oil Recovery methods
Gross reserves 300-600 million barrels
Development • High reservoir exposure: horizontal oil
strategy producers with geo-steering
• Flow assurance: electrical submersible pumps
• Produced water re-injection

3. Leveraging our technological know-how
Multi-lateral wells Advanced Autonomous inflow
geosteering control valves • Build on key areas of Statoil
expertise to improve oil
recovery at Peregrino
Objective: higher reservoir Objective: improved well Objective: reduced inflow
exposure and reduced cost placement of water in oil producers
Concept: branched wells Concept: advanced Concept: self-adjusting
logging-while-drilling tools valves
Infill wells Optimised water
injection strategy
Polymer injection
• Technology development
can benefit other heavy oil
assets in our portfolio
Objective: higher reservoir Objective: improved Objective: improved
exposure sweep in the reservoir sweep in the reservoir
Concept: identify new Concept: optimise number Concept: inject polymer to
drilling targets and placement of injectors increase water viscosity
