Well Construction | GoPort Interventionless Toe Sleeves

GoPort Interventionless Toe Sleeves

NCS Multistage GoPortTM sliding sleeves are a simple, sure way to achieve initial formation access for any completion. There are two versions:

  • GoPort SAT: Signal-actuated and testable; will not shift open until it receives a specific pressure-profile signal, allowing unlimited casing pressuretests without risking premature actuation. Forms a ball seat on opening to enable subsequent casing pressure tests using a dissolvable ball.
  • GoPort PAT: Pressure-actuated and testable; shifts at a preset pressure and forms a ball seat on opening to enable subsequent casing pressuretests using a dissolvable ball.
  • GoPort PA: Pressure-actuated; shifts at a preset pressure.

    .

All three versions are self-shifting without intervention, using well pressure acting against stored atmospheric pressure. After the sleeve opens, you can perform an injection fall-off test, flush the wellbore to avoid a cleanout run, pump perforating guns, plugs and other tools to the toe, or execute a first-stage fracture.

 

Features

  • Eliminate the need for a tubing-conveyed-perforating run
  • Work with all sleeve-type or plug-and-perf completions
  • Full ID with no restrictions and slim OD for easy run-in
  • Compatible with cemented or open-hole completions
  • Compatible with high-density cement
  • Do not interfere with cementing operations
  • Mandrel design matches or exceeds casing string yield and
    torque ratings
