Make sure your first line of defense is doing its job, and spot where it’s not

Primary barriers are the first line of defense in protecting well system integrity. Failures here need to be diagnosed quickly to avoid unsafe operations, lost production and the risk of escalation.

Primary Seal locates leaks and evaluates the seal performance of all primary barriers quickly and accurately, throughout the well system.

 

Delivered by our True Integrity system with Chorus technology, Primary Seal provides a clear diagnosis of leaks and unwanted flowpaths so the right corrective action can be taken, and barriers can be validated to confirm integrity.

 

Primary Seal is used in a targeted fashion to pinpoint a suspected integrity breach in the tubing or other primary barrier components. Following proper diagnosis, breaches can be fixed more reliably and efficiently.

 

Primary Seal Integrity provides a clear diagnosis of leaks and unwanted flowpaths so you can take the right action.

Challenges & applications

  1. Evaluate seal integrity of primary barriers
  2. Sustained pressure in A-annulus [SAP]
  3. Abnormal production or injection performance
  4. Primary barrier leaks
  5. Micro-leaks in primary barriers
  6. Leaks in completion components such as gas-lift valves and mandrels
  7. Tubing pressure test failure
  8. Validate sealing performance of primary barriers
  9. Workover or P&A planning
  10. Post-workover or P&A validation
