US Patent 12018544 Completion isolation system with tubing movement compensator

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.
