Tieback liner

A tieback liner is a section of liner that is run from a liner hanger back to the wellhead after the initial liner and hanger system have been installed and cemented.

Tieback liner applications are:

to repair damaged or worn casing above the existing liner
to ensure casing integrity upon completion of drilling operations - Installing a tieback casing liner at completion of drilling operations provides a casing within the well that has not been exposed to rigorous of drilling operations
to provide added casing protection against corrosion or pressure anomalies

Utilizing the WEA for Tieback Liner provides a robust and reliable solution for tieback liner applications compared to traditional solutions. It enhances well integrity, reinforces the existing casing string, and ensures the stability and integrity of the wellbore, ultimately optimizing well performance.
