High Performance ESeal Liner Restores Well Integrity

Summary:

An Operator required restoring integrity to their 13-3/8" 72 lb/ft casing on a suspended Central North Sea well.

 There was a known leak at the mud-line suspension system (MLS) which needed to be isolated prior to continued operations. Cement plugs deeper in the well were to be drilled out therefore integrity in the wellbore above this point was paramount for a safe operation. The shallow leak point presented additional complexity to the repair procedure.
