Tri-DPort

Tri-DPort combines the advantages of PremiumPort™, a dynamically configurable nozzle based downhole inflow and injection control tool, with Tri-DPro™ sand control that is more effective and more economical than conventional premium screens for unconsolidated formations with non-uniform sands.

Tri-DPort™ is configured at the well site with flow control or injection control nozzles installed within the PremiumPort tool.

Following deployment, the multi-position valve within PremiumPort can be shifted to close or open nozzles as required, which gives operators the flexibility to change the pressure profile along a lateral repeatedly over the life of the well. Multiple PremiumPort units can be installed with either screen or blank joints between them. Being able to tailor flow control aids in removing formation damage from drilling and completion fluids, delaying water influx over time, and optimizing toe-to-heel inflow. Screen sections are made with Tri-D Weave without welding the media thus avoiding any risk of burn through, pin holes or faulty welds. This next generation premium screen has high open flow area plus high strength and resilience against load forces in horizontal wells.

The Challenge

Well completion decisions must deliver optimum productivity and long well life to recover reserves. Operators are recognizing that all the intervals along laterals do not contribute production equally. They need effective ways to better manage the pressure profile from toe-to-heel of the well in order to clean up drilling fluids and to delay water influx as the well ages. Also, sand entering the wellbore over time is another operational concern, as this can reduce well productivity, damage surface facilities, or worse, cause expensive remediation and catastrophic well failure.

The Solution

Tri-DPort combines the most flexible flow control technology in the market with the top performing filter media for oil and gas reservoirs. Nozzles are viscosity independent which leads to delayed water influx.

  • The flow control capability integrated into Tri-DPort can also be tailored to reservoir potential at each interval based on the style and orifice size in the nozzles.
  • The flow control capability can be modified over the life of the well by activating a multi-position valve downhole to close or expose nozzles.
  • Unlike gap based screens, Tri-DPort screen sections are made with Tri-DPro media and have 40% open flow area, high plugging and erosion resistance and do not require detailed and expensive particle size analysis.

Advanced Flow Control for Enhanced Well Productivity

Tri-DPro screen integrated into Tri-DPort stops harmful sand from entering the wellbore. Fluid flows through the filter media, along grooves in the base pipe to the nozzles. Unlike channel or tube-based inflow control devices (ICDs), nozzles are viscosity independent flow control devices that inhibit water influx.

The chart below shows the measured pressure drop for various fluid viscosities passing through a 4.00 mm nozzle.

A large flow area between the screen media and the base pipe prevents erosion and any undesirable pressure losses.

Tri-DPort Applications

Tri-DPort is best suited for unconsolidated, non-uniform sands and reservoirs with corrosive conditions. The nozzles are configured for inflow or injection control at the wellsite prior to deployment.

  • Horizontal producer or injector wells requiring pressure profile control and sand control along the entire wellbore
  • Vertical wells with commingled zones of different pressures
  • Thermal wells that require uniform toe-to-heel steam injection
  • In combination with external/swell packers to isolate zones and minimize annular flow

Benefits

After deploying Tri-DPort, the multi-position valve can be shifted to expose ports which can be plugged, left as open ports, or fitted with nozzles for injection or inflow flow control. The valve can be reliably re-positioned down hole to select ports in any order, and as many times are required using the Harrier shifting tool on coil tubing. Ports/nozzles are opened or closed to change the pressure profile along the lateral, shut off intervals, or stimulate the well.

  • To facilitate uniform toe-to-heel sweep of reservoir
  • To delay the onset of water/gas/steam coning for increased reserve recovery and net present value
  • To choke off water zones and isolates shale zones

A number of factors influence proper completion design for injection, inflow and sand control across a lateral. Absolute’s Technical Application Managers are available to assist you in achieving optimal well performance through:

  • Down hole flow control design and configuration options
  • Screen options that balance long term well productivity and effective sand control with cost considerations

Tri-DPort Options Available

Tri-DPort can be tailored to the reservoir profile by selecting the style and location of nozzles:

  • CrossFlow nozzles direct flow horizontally and are used to reduce flow velocity into the liner and to eliminate any concern of eroding coil tubing instrument lines, or erosion induced corrosion

  • SecureFlow nozzles are used for high temperature applications such as thermal heavy oil production or steam injection

image015

  • Standard nozzles direct flow vertically through the nozzle and are used for conventional oil and low flow velocity applications

Flow control strength can be tailored by selecting from various orifice size options:

  • 0.157 inch (4.00 mm) standard
  • 0.098 inch (2.50 mm)
  • 0.063 inch (1.60 mm)

Customized screen lengths can be supplied. Typical Tri-D screen assemblies have:

  • 32 feet of screen on 38 feet of base pipe
  • 24 feet of screen on 30 feet of base pip
