Abstract
A system includes a tubular disposed within a borehole, a sleeve disposed around the tubular, and an isolation element bounded to an outer diameter of the sleeve. The inner diameter of the sleeve is connected to an outer diameter of the tubular via a plurality of seals. The isolation element is configured to conform to a surface of the borehole when the isolation element is in an expanded configuration. The sleeve compensates for movement of the tubular by being able to freely move across the tubular.

A system, comprising:
- a tubular disposed within a borehole;
- a sleeve disposed around the tubular, an inner diameter of the sleeve being connected to an outer diameter of the tubular via a plurality of seals;
- and
- an isolation element bonded to an outer diameter of the sleeve, the isolation element configured to conform to a surface of the borehole when the isolation element is in an expanded configuration,
- wherein the sleeve compensates for movement of the tubular by being able to freely move across the tubular.

A method, comprising:
- deploying a completion system into a wellbore, the completion system comprising:
- a tubular;
- a sleeve disposed around the tubular, an inner diameter of the sleeve being connected to an outer diameter of the tubular via a plurality of seals;
- and
- an isolation element bonded to an outer diameter of the sleeve,
- wherein, during the deploying step, the isolation element is in an unexpanded configuration;
- actuating the isolation element such that the isolation element conforms to a surface of the borehole in an expanded configuration;
- and
- maintaining an integrity of a first bond between the isolation element and the outer diameter of the sleeve, and a second bond between the isolation element in the expanded configuration and the surface of the borehole by allowing the sleeve to freely move across the tubular.
