LIBRA Extended Well Test: Getting Ready for First Oil Francisco Costa Joint Venture Operator

Slide 2 Several Industry Firsts: EXTENDED WELL TEST IN LIBRA First FPSO dedicated for EWT with gas injection First use of 8 production flexible line First Production line pre-laying with buoys Largest External Turret in Ultra Deep Waters Swivel operation with the highest gas injection pressure

EXTENDED WELL TEST IN LIBRA EWTs: Reduction of uncertainty by understanding dynamic behavior is crucial to optimize final production systems. Production Unit Oil Capacity: 50 mil bbl/d Gas Compression: 4.0 MM m 3 /d Wells Production Well NW-3 Wells Gas Injection Well NW-2

MAIN UNCERTAINTIES X INFORMATION ACQUIRED Long term dynamic performance of wells and reservoir. Minimum connected oil in place, reservoir boundaries and detection of sealing faults Detection of conductive fractures and/or super-k layers. Flow assurance issues and efficiency of mitigating actions. EWT MAIN IMPACTS Drainage plan - optimal number and location of wells & subsea design. Production and injection strategy. More reliability in the production forecasts.
