Agenda


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

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

Without ICD With ICD

EquiFlow Inflow Control Device


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 Inject System


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

EquiFlow Systems - Applications


EquiFlow ICD – Flow Path


Sandstone formation - ICD with Mesh screen

Sandstone formation – ICD with Wrap-on-Pipe screen

Carbonate formation - ICD with Strainer (Wire-Wrap)

EquiFlow ICD – Common Assemblies


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)

EquiFlow Systems Configuration


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
