EquiFlow Inflow Control Device Homogenous reservoirs  Horizontal wells provide  Greater reservoir contact  Higher production than vertical wells with lower drawdown

 Frictional forces in the tubing can be significant  Early water and/or gas breakthrough in the heel

With ICD 3

EquiFlow Inflow Control Device Heterogeneous reservoirs  Equalizes the pressure drop along the interval for a more efficient completion  Longer producing life due to delay of water/gas coning  Production per unit length improved

 Decreased flow rate of high mobility fluids  Better sweep efficiency

With ICD 4

EquiFlow Inject System  Similar design to the EquiFlow ICD, but takes injected fluid properties into consideration  Allows for a more homogeneous placement of the injection fluid  Application – Avoids breakthrough of injected fluid into producers – Better placement of injection fluid into different formation layers – Evens out effects of permeability differences and fractures

EquiFlow Adjustable ICD  Adjustable EquiFlow systems  Pre-configured with a set of tubes  Re-configure tubes on rig to change the pressure drop

 Updated info from LWD/MWD

EquiFlow Adjustable ICD Slide housing for flow tube access

 What info do you get from logging tools?  Will this info change your EquiFlow ICD configuration?

 Provides greater configuration and supply flexibility Fixed EquiFlow system

EquiFlow – Why Choose a Tube?  Halliburton’s tube ICD technology bridges the nozzle/helix performance gap 30% less sensitive than a nozzle to a change in pressure drop from erosion 60% less sensitive than a helix to a change in flow rate with water breakthrough © 2009 Halliburton.
