Tri-DFlux

Tri-D Flux™ integrates nozzle based downhole flow control with Tri-DPro™, sand control for an advanced flow control – sand control solution that solves the challenges of the most demanding reservoir environments.

Tri-D Flux is configured with viscosity independent flow control nozzles that choke off water influx and enhance the inflow of oil. Nozzle style, size and placement are tailored at the wellsite prior to install using reservoir modelling and well log data to design an optimum flow control profile.

Tri-DPro is formed by fusion bonding Tri-D Weave™ media to stainless steel perforated shroud material. The rolled sintered shroud forms a cylinder with the Tri-D Weave media on the inside. Only the shroud seam is welded to close the cylinder. The cylinder is installed over the perforated base pipe with shroud ends welded to the base pipe. The filter media is never exposed to the risks of burn through, pin holes or faulty welds and it offers high open flow area plus high strength against load forces in horizontal wells.

The Challenge

Drilling long laterals is expensive and adds complexity to completion decisions.  Formation characteristics and particle size distributions vary which makes optimizing production at every lateral section difficult. Completion engineers face three significant challenges:

  • Enhanced lift systems that increase draw down also tend to promote water coning, sand influx, and screen erosion – all of which increase operating costs and shorten well life.
  • Accurate sand sampling and analysis for sizing conventional gap based screens is difficult and costly.
  • Running conventional gap based screens into long laterals can distort the gap structure making the screen ineffective in controlling sand.

The Solution

Tri-D Flux is an all-in-one completion delivering flexible flow control with weldless, next generation Premium sand control.  Sections with nozzles can be integrated with either screen, or blank joints.  Nozzles can be on each joint, or spaced out over several joints to optimize both the completion costs and the pressure profile. No gap sizing is required because Tri-DPro’s varied three dimensional pores stop sand while maintaining exceptional retained permeability at the sand-screen interface.

  • Tailored pressure profile control
  • Exceptional open flow area
  • Retained permeability
  • Plugging resistance
  • Erosion resistance
  • Strength

Tri-DFlux Performance

Tri-DFlux maximizes well productivity by equalizing the drawdown and influx from toe-to-heel of the well to delay water influx and by  controlling a wide range of sand particles.

  • Nozzles and screen are engineered for the most severe installation and operational conditions using corrosion resistant alloys
  • The Tri-D Weave filter media exceeds both the initial and retained permeability of conventional Premium screens and is ideal for controlling sands with widely varying particle sizes
  • High initial open flow area and high plugging resistance ensure high retained permeability in the critical near wellbore area

Tri-DFlux offers high strength for deployment into long laterals with tight trajectories.

Viscosity Independant Flow Control Equalizes Drawdown from Toe-to-heel

Unlike Channel or Tube-based inflow control devices, nozzles are viscosity independent as shown below.

Tri-DFlux Applications

  • A structurally stronger alternative to slotted liner and wire wrap screens to accommodate wider application stress limits
  • High pressure, high-temperature, high-corrosion environments
  • 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.

Benefits

Tri-DFlux flow control integrated with Tri-DPro sand control extends well life and increases reserve recovery by:

  • Facilitating uniform sweep efficiency across the horizontal well
  • Equalizing draw down from toe-to- heel of well
  • Preventing or delaying gas and water coning
  • Choking off hi-permeability water zones
  • Removing filter cake, especially at the toe for added production
  • Avoiding formation damage from drilling and completion fluids or operations
  • Allowing versatile completion geometries due to the strength to withstand load forces during deployment and operation

Tri-DFlux Options Available

Tri-D Flux flow control can be tailored to the formation by selecting the style, size, number and location of the nozzles:

CrossFlow nozzle production and injection applications:

  • Wells with instrumentation deployed within the casing string that must be protected from any risk of jetting
  • Wells with high pressure fluid production to reduce the 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

SecureFlow Nozzle – Cyclic steam, SAGD heavy oil, high pressure gas production and high pressure steam or water injection

StandardFlow Nozzle – Moderate flow rate, moderate pressure wells that do not have instrumentation deployed downhole

CrossFlow, SecureFlow and StandardFlow Nozzles

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

  • Fine, medium or coarse weave filter media
  • Standard 316L Stainless Steel, or corrosion resistant alloys: HastelloyTM, InconelTM, A20, or A625

Circulate in to Save Rig Time and Costs

During manufacture, the sand control joints can be coated with a formation specific wax or other impermeable, but soluble material to seal the media.  Once deployed, the temporary coating is removed using heat or solvent to open the flow area for production. Sealing the screen with a removable substance allows screens to be circulated through difficult hole conditions and to target depth in long horizontals.
