Cement placement in the well is critical for construction and decommissioning activity. The CX-IST (Inflation Support Tool) improves cement placement and significantly reduces rig-time.
The tool can be deployed from surface down the work string. Once it has landed out, pump pressure inflates the elastomer creating a 100% seal between the tool and the casing wall or formation, providing a positive indication that the cement will be set in the correct location. It is then released by simply picking up the work string.
The tool creates a 100% wall-to-wall base for well fluid or cement. As the same landing sub can be used several times, the operator can deploy as many CX-ISTs as needed in the same or multiple zones.
