Total Losses Zones

Multi Stage Cementing

Loss zone seal off

Total losses zones can significantly increase the complexity, risk, uncertainty and cost of drilling a well.
Saltel Industries has developed different an alternative to seal off total losses zones in the annulus:

Xpandable ECP (External Casing Packer), combined with a cement port, will be a useful and permanent annulus isolation barrier, to ensure the cement is properly set above the total losses zone.

Saltel Expandable Packers combined with a stage collar enable cementing above troublesome formations in several stages. We have developed two product ranges specific to stage cementing and off-bottom cementing. The packer can be used either as base for the cement (ECP) or as long term annulus seal (AZIP).
