FlowCAT retrofit wireless safety valve


Where the tubing retrievable safety valve or control line has failed, FlowCAT provides a more dependable alternative to ambient valves or storm chokes. Being retrofitted, surface controlled and fail-safe, FlowCAT provides a cost effective alternative to performing a well workover and enhances the integrity and safety of the well.

The CaTS™ wireless telemetry is also being used to control the FlowCAT retrofit downhole safety valve which can be deployed into the well using  slickline.  A signal is transmitted continuously from surface which keeps the valve open.  If the signal transmission is interrupted or an emergency shut down event occurs then the valve closes, providing a fail safe system which offers several  advantages over traditional ‘storm chokes’.

Features and benefits:

  • Retrofitted into the well using conventional wireline equipment and procedures
  • A fail-safe valve controlled from surface using Expro’s well proven CaTS
  • Resettable from surface by the application of pressure
  • Non-elastomeric sealing faces for enhanced sealing and well safety
  • Capable of withstanding high differential unloading across the sealing faces
  • Qualification testing completed in accordance with a modified ISO 10432 class 1 test procedure
  • No wellhead modifications or recertification required
  • Targeting 6 to12 months between battery change outs
     

Expro is proud to have won a Spotlight on New Technology Award at the 2010 Offshore Technology Conference with the FlowCAT™ Wireless Safety Valve System.
