Validate sealing performance of completion packers

Completion packers are an essential part of the integrity envelope, but their sealing performance can degrade over time. Rapid diagnosis is essential to restore safe and productive operations.

 

Packer Seal Integrity evaluates the seal performance of packers, locating leaks quickly and with precision.

 

Delivered by our True Integrity system using the Chorus (acoustic) platform; Packer Seal Integrity provides a clear and convenient diagnosis of packer integrity so the right corrective action can be taken.

 

Packer Seal Integrity is used in a targeted fashion to diagnose suspected packer leaks, and proactively to ensure correct operation. With proper diagnosis, the well can be restored to normal operations.
