Dual String Tube Integrity

Evaluate tube integrity of dual completions

Assessing the integrity of dual completions is challenging. Access below the short string is often blocked, and the geometry can be too complex for ordinary electromagnetic inspection systems.


Dual String Tube Integrity brings all the accuracy benefits of Multi Tube to dual completions, assessing up to four concentric tubulars from a single through-tubing deployment.


Powered by our True Integrity system and Pulse (electromagnetic) platform; Dual String Tube Integrity is the industry’s most accurate multi barrier diagnostic product for dual completions.


Dual String Tube Integrity, if used routinely, can support your ongoing integrity management programme, or in a targeted fashion to investigate a specific integrity breach.


Our ability to assess up to four concentric tubulars simultaneously means that most of the well can be evaluated in a single deployment, without pulling the tubing.



  • Managing tube integrity of dual completions
  • Routine or targeted surveillance of tubulars in dual completions
  • Time-lapse barrier condition monitoring
  • Assessing maximum allowable annular surface pressure (MAASP)
  • Assessing tube condition in the presence of scale
  • Verifying completion design


  • Track and validate tube condition over time and spot tube weakness before it fails
  • Through-tubing deployment minimises disruption and cost
  • Comprehensive validation of barrier condition in a single run
  • Understand true wall thickness
  • Identify internal vs. external defects in primary tubes (when used with caliper)
  • Better remediation decisions, precisely targeted
