Two-for-one integrity diagnostics, reaches the parts others can’t

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 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 technology, Dual String Tube is the industry’s most accurate multi barrier diagnostic product for dual completions.

 

Dual String Tube is used routinely to 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.

Dual String Tube Integrity is the most accurate multi barrier diagnostic product for dual completions.

Challenges & applications

  1. Evaluate tube integrity of dual completions
  2. Managing integrity of dual completions
  3. Routine or targeted surveillance of tubulars in dual completions
  4. Time-lapse barrier condition monitoring
  5. Assessing maximum allowable annular surface pressure [MAASP]
  6. Identifying internal and external defects
  7. Assessing tube condition in the presence of scale
  8. Verifying completion design
  9. Pre-workover, pre-handover, or pre-abandonment assessment

Insights & benefits

  1. Proactive integrity management mitigates risk and maintains safe and productive operations
  2. Track and validate tube condition over time
  3. Spot tube weakness before it fails
  4. Through-tubing deployment minimises disruption and cost
  5. Comprehensive validation of barrier condition in a single run
  6. Understand true wall thickness
  7. Identify internal vs. external defects in primary tubes [when used with caliper]
  8. Better remediation decisions, precisely targeted
  9. Maintain regulatory compliance
  10. Maintain well system integrity
