Annular metal packer

General Description
General Description Features & Benefits Specification Related Resources
Most robust, reliable, and ragged design in the industry
Casing/liner integrity re-instated post setting
No degradation in differential pressure, constant and high values over full expansion range
Compensation system for high pressure ΔP
High expansion capability and No premature activation
Additional sealing length can be modelled and designed on request
Eliminates the need for cementing
Can be rotated with casing string while running in hole which increases probability casing to TD in challenging wells and reduces operators' risks
Can be rotated during primary cement operations enhancing cement placement
Slim OD provides for higher circulation rates during operations
Very fast setting operation saves operator time and reduces complexity
Full bore drift as per base casing pipe

General Description

Annular metal packers have a significant advantage over conventional packers for its specially designed seal formed by the hydraulically expandable metal sealing element of the packer. When hydraulically expanded, the strengthened sleeve mimics the wellbore/ casing geometry, thus boosting the packer’s resistance to pressure variations. AMP is cased hole pressure barrier rated as per IS0 14310 V0 and best in the industry (SCP – sustained casing pressure) solution.

Open hole pressure barrier rated as per IS0 14310 V3.

Cementing quality assurance in open hole rated as per IS0 14310 V3.

Solution to address well fluids and gases cross flows / Casing integrity assurance. Most robust, reliable and ragged design in the industry / Well life barrier.
