What well integrity means to Xpandable steel packer technology

Well Integrity is the Design, Installation, Operation and Maintenance of all Well Equipment to a standard that ensures the safe containment of Produced well fluids and Injectants for the life of the well.
Saltel Xpandable steel Annular Zonal Isolation Packer (AZIP) technology offers a simple, standalone means of achieving downhole annular zonal isolation. In addition, selective cementing of specific zones, achieved through the use of Saltel Xpandable steel External Casing Packer (ECP) and stage collar system, allows for leaving unwanted thief zones uncemented.
