Casing Integrity

How to restore Casing integrity?

Casing integrity may be jeopardized due to corrosion, to mechanical failure, or to perforations to seal after cement remediation operations. If cement remediation requires casing perforations, then an expandable steel patch can be used to provide pressure integrity across the perforations.
If casing pressure test cannot be achieved due to mechanical failures such as leaking DV tool or casing collar leak, a similar approach can be used to achieve pressure integrity.
Operators need a reliable solution to cover up and isolate sections of the damaged casing, and to withstand at the same time high differential service pressure ratings, both internal and external.

You can restore the integrity of a damaged casing using Saltel Xpandable Steel Patch.
