Cement Backup

 

Cement provides casing annulus seal between the reservoir, geological formations and the surface during the life of the well. Therefore, any issue encountered during the placement, curing or after several years can lead to major safety and environmental issues.
Set in the uncured cement sheath, Saltel Expandable Steel packers compartmentalize the annulus into independent parts, preventing channeling and micro-annulus from spreading between them the curing phase. As solid and permanent expanded metal packers, they also guarantee long term annulus and provide back-up to cement during the life of the well.
