A Presentation of Two Technologies

• Inflow Control Devices

– Horizontal wells: permeability contrasts, fractures, frictional losses, thin oil columns, mobility variations

• Intelligent Completions

– Multiple horizons, horizontal wells: zonal heterogeneity, critical production management


Passive ICD System – viscosity “independent”

• Pressure drop a function of density and rate squared


Autonomous ICD – “A levitator” ??

• Bernoulli – “Sum of Static Pressure, Dynamic Pressure and Friction loss along a streamline is constant”

• Low viscosity - reduces friction pressure, causes high velocity thereby “sucking” the disc against the seat restricting flow

• High viscosity - increases friction pressure – pushing the disc away from the seat and thereby increasing flow

TR7 Characteristics - Oil, Gas and Water

Low viscosity -High DP !!

High viscosity - Low DP !!

Gas Control with Choked Flow !!

High viscosity - Valve is open

AICD – viscosity dependency in “reverse”
