Multistage Cementing

Cementing above openhole completion (slotted casing, screens) or above troublesome formations in several stages can be achieved with Saltel Expandable Steel Packers combined with a stage collar. Two product ranges specific to stage cementing and off-bottom cementing have been developed whether the packer is to be used either as base for the cement (ECP) or as long term annulus seal (WI-AZIP). SES-ECP have been designed to operate at low pressure with standard casing weights and materials whereas the WI-AZIP has a large material selection and it features a V0 rated expansion valve.
