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
Without ICD With ICD

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
Without ICD With ICD

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 inflow control device (ICD)– Oil Producers
• Coning due to heel-toe effects Sandstone• Fractured intervals Carbonate• Permeability/mobility differences Carbonate• Reservoir pressure variations• High oil viscosity wells• Thin oil columns
EquiFlow Inject system– Injectors
• Even distribution of injection fluid• Breakthrough of injected fluid into nearby producer

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
What info do you get from logging tools?
Will this info change your EquiFlow ICD configuration?
Provides greater configuration and supply flexibility

Pressure drop across tubes determined by:
Tube length (standard 4” length)
Tube ID (depending req. pressure drop)
Number of tubes (normally 3-5 tubes per ICD)

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
