LIBRA Extended Well Test: Getting Ready for First Oil Francisco Costa Joint Venture Operator
Slide 2 EXTENDED WELL TEST IN LIBRA Several Industry Firsts: � 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. .
