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.
