Innershield™ screens

Long Life in Severe Service

InnerShield™ sand-control screens provide long life and optimized production in wells with harsh downhole conditions. They resist erosion and abrasion with a patent-pending design that directs and disperses fluid flow to avoid localized hot spots and maintain the integrity of the filter media.

Designed for Durability

In sand screens, erosion occurs from the inside out and initiates at perforations. InnerShield™ screens are designed to neutralize these factors.

InnerShield™ screens are built using a patented process that combines base pipe, support core, filter media, and protective shrouds into a single, unitized joint with layers locked tightly in place.

The inner shroud is manufactured so its hole pattern is offset from the base pipe perforations, effectively diffusing the incoming fluid over the entire screen surface and preventing damaging localized erosive conditions. Furthermore, standoff is optimized to minimize pressure drop and maximize the effective filter area.

The result is a sand screen that lasts longer in the toughest downhole conditions.


  • Erosion and abrasion resistance
  • Mechanical strength
  • Reliable filtration
  • Unitized cartridge design
  • Simple, fast installation
  • Compatible with sintered mesh construction
  • Design and production flexibility
  • Meets the toughest producer and service company testing requirements


Innershield™ screens perform reliably in your most challenging applications:

    • Wells with severe downhole conditions
    • Open-hole and cased-hole completions
    • Stand-alone completions
    • Gravel-pack and frac-pack completions
    • Vertical, deviated and horizontal completions
    • High flow-rate producers
    • Long and extreme-reservoir-contact wells
    • High GOR wells

    Flow Distribution

    Testing confirms improved flow distribution through the screen by the addition of the inner shroud. The InnerShield® screen exhibits significantly reduced exit velocity of fluids underneath the screen compared to a conventional screen design, thereby protecting the screen against erosion (after SPE 208817).
