Tri-D FacsFlux

Integrated Management for Sand, Inflow, and Injection

Tri-D FacsFlux™ optimizes well production with a combination of sand control and flow control for wells with down hole pressures below 1500 psi.

Tri-D FacsFlux allows operators to create multiple zones within a lateral, or well, and control the flow out of, or into each of those zones. The strategically sized and positioned nozzles are viscosity independent devices that improve the sweep efficiency along a lateral, aid clean up at the toe, and extend well life by delaying or preventing water breakthrough into the wellbore.

For very high temperature, high pressure wells above 1500 psi we recommend Tri-D FacsFlux HP, which has the addition of disc retention rings which take the burst pressure rating of the screen to 3000 psi.

Tri-D FacsFlux sand control sections have filtration discs made of Tri-D Weave™ media flush mounted into a robust outer sleeve of variable length which is mounted to the base pipe. The nozzles are positioned towards the end of the base pipe. The result is an exceptionally strong sand-flow control completion with outstanding open flow area and plugging resistance that includes configurable pressure profile control. Tri-D Weave is a new, next generation filter media with higher open flow area and higher plugging resistance than conventional square or Dutch weave laminates.

Nozzle Flow Control with Tri-D FacsRite or Standard FacsRite Sand Screen

The Challenge

Running conventional gap based sand control into long laterals can distort the gap structure of these sand control systems thus degrading sand control effectiveness. Gap based screens must be properly sized to be effective and highly variable formation characteristics and particle size distributions make detailed sand analysis for designing gap based screens costly. In addition, enhanced lift systems used to increase draw down tend to promote water coning, sand influx, and erosion – all of which increase operating costs and shorten well life.

The Solution

Tri-D FacsFlux is an all-in-one flexible flow control and superior sand control completion. The 3-D varied pore sizes of Tri-D FacsFlux stop sand while maintaining exceptional open flow area and retained permeability at the sand-screen interface. Sections with nozzles can be integrated with either screen or blank joints to tailor the completion to the formation requirements. Nozzles can be on each joint, or spaced out over several joints to optimize both the completion costs and the pressure profile.

Flow control nozzles are viscosity independent orifices that choke off water and enhance the flow of oil into producing wells. They are made of tungsten carbide and coated with titanium nitride for maximum erosion and corrosion resistance. Unlike static inflow control devices, the pressure profile control of a nozzle based flow control system can be tailored at the wellsite. The reservoir is modelled using simulation software and well log data to quickly and accurately design the optimum nozzle size and locations.

The robust construction makes Tri-DFacsFlux ideal for ultra-long reach laterals in consolidated reservoirs such as carbonates. Passive flow control devices are not adjustable post installation.

Why Is Understanding Sand Retention And Flow Behavior At The Sand-Screen Interface Important?

Tri-D FacsFlux Applications

FacsFlux offers a structurally stronger alternative to slotted liner to accommodate wider application stress limits. The integration of viscosity independent flow control is ideal for:

  • Wells were a large ID to OD ratio is desirable or liner OD is a critical factor
  • High pressure, high temperature, high corrosion environments
  • Horizontal and vertical Cyclic Steam Stimulation (CSS) wells
  • Long horizontal wells drilled into semi-consolidated and unconsolidated formations
  • Vertical/slanted wells commingling zones with different pressures and permeabilities
  • Horizontal and vertical SAGD and Cyclic Steam thermal wells for uniform toe-to-heel steam injection
  • In combination with swell packers to isolate problematic water, gas or thief zones
  • Vertical or horizontal gravel pack or frac-pack screen with flow control
  • High temperature steam and water injection wells.

Tri-D FacsFlux Options Available

Flow Control Options Available


  • Wells with instrumentation in the casing string that must be protected from risk of jetting
  • Wells with high pressure fluid production to reduce jetting velocity into the wellbore
  • Wells susceptible to velocity induced corrosion
  • Vertical wells in consolidated formations with commingled zones of different pressures


  • Thermal wells requiring uniform and high velocity, high temperature steam or water injection from toe-to-heel

Secure Flow Nozzles:

  • High temperature, pressure and flow rate production and injection applications

Standard Nozzles:

  • Moderate flow rate, temperature and pressure production and injection applications

Sand Control Options Available

Tri-D FacsRite sand control can be tailored to the formation production capability, open flow area, completion cost, and the harshness of the reservoir conditions by selecting:

Weave Density:

  • Fine, medium or coarse weave filter media

Material for discs and base pipe:

  • Standard 316L Stainless Steel, or corrosion resistant alloys: Hastelloy™, Inconel™, A20, or A625
  • 3/4 inch (190.5 mm)
  • 1 inch (254 mm) diameter discs
  • Filter elements can be installed in customer supplied base pipe

Standard sand control elements are made with sintered layers of woven metal mesh with the same torsion and collapse strength as Tri-D FacsRite. However, these conventional Premium media discs have lower open flow area and plugging resistance compared to the new, next generation Tri-D Weave filter media used in Tri-D FacsFlux, but have proven reliable in many applications around the world.

Extreme Environment Options Available

  • For very high temperature, high pressure wells above 1500 Psi we recommend which has the addition of disc retention rings which take the burst pressure rating of the screen to 3000PSI.
  • For operators completing wells in reservoirs where long productive well life for optimum reserve recovery with minimum remedial intervention is important we recommend , and which allows dynamic flow control over the life of the well.
