Keep a close eye on your first line of defense, even if you have scale

Production tubing and casing need to connect reservoirs to surface safely and productively. Tracking the condition and wall thickness of primary tubulars is essential to maintaining a secure well.

Primary Tube provides the same accuracy advantages of Multi Tube tailored for the production tubing or primary casing barrier.


Powered by our True Integrity system and Pulse technology, Primary Tube delivers accurate wall thickness data – even if you have scale.


Primary Tube is used routinely to support your ongoing integrity management programme, or in a targeted fashion to investigate a specific integrity breach. And our ability to reveal actual wall thickness and external defects makes it the ideal complement to conventional caliper type investigations.

Primary Tube Integrity delivers true wall thickness data even if you have scale.

Challenges & applications

  1. Evaluate tube integrity of primary tubulars
  2. Managing integrity of primary tubulars
  3. Routine or targeted surveillance of primary tubular condition
  4. Time-lapse barrier condition monitoring
  5. Identifying internal and external defects
  6. Assessing tube condition in the presence of scale
  7. 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 tubing weakness before it fails
  4. Slickline deployment minimises disruption and cost
  5. Understand true wall thickness
  6. Identify internal vs. external defects in primary tubes [when used with caliper]
  7. Complement and improve multi finger caliper surveillance
  8. Understand true wall thickness behind scale
  9. Better remediation decisions, precisely targeted
  10. Maintain well system integrity
