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

EWT MAIN IMPACTS
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
� Drainage plan - optimal number and location of wells & subsea design.
� Production and injection strategy.
� More reliability in the production forecasts..
