Cytadel ZX Electronically-Actuated Packer

Stop dangerous sustained casing pressure and improve rigsite efficiency

Eliminate gas migration and decrease the risk of blowouts related to sustained casing pressure (SCP).

The Cytadel ZX™ electronically-actuated packer creates a gas-tight barrier in the outer annulus between production zones and the surface to protect against dangerous SCP build-up and reduce HSE risk. When the sealing integrity of cement becomes compromised, pressure can increase to hazardous levels and requires ongoing bleed-off operations. The V0-rated ZX™ seal element provides an added layer of protection that prevents gas migration, eliminating SCP-related bleed-off costs and production interruptions.

The packer is remotely actuated from the surface, saving hours of rig time. And its solid-body mandrel maintains the integrity of the casing by eliminating dependence on conventional elastomeric seals.

The Cytadel ZX packer is the only casing packer that combines ZX seal technology, a solid-body mandrel with tubular connections, and a remotely-activated electronic trigger. It establishes an annular barrier that eliminates SCP, protecting both people and the environment, while simultaneously improving operational efficiencies.
