Multizone completion

The multizone annular zonal isolation packer (AZIP 1-1) uses patented Saltel Xpandable steel technology which consists of the permanent and controlled deformation of a metallic sleeve covered with sealing arrangements.
Hydraulic pressure expands the packer (up to 30%). The sleeve adapts to the actual shape of the well, and the sealing system is energized against the borehole.
There is no need to trap fluid or pressure inside the packer. The packer sleeve gets its remarkable pressure rating from the dual-compensation system.

The dual compensation system

The multizone isolation packer comes with a unique system of compensation valves. These valves have been developed and qualified to balance the pressures acting on the packer and provide a dynamic isolation function. The highest pressure, where ever is coming from, is authorized to enter the packer’s chamber and is used to enforce the sealing performance, leading to a Life-of-the-well 15,000psi differential service pressure rating across the element on both sides.

Ovalized boreholes

The packer is designed to seal the annulus in difficult open hole conditions. It has

The packer is designed to seal the annulus in difficult open hole conditions. It has completed high standard qualifications to provide an effective sealing in boreholes up to 9% ovality.
The AZIP 1-1 maintains sealing performance in all well conditions, during stimulation and production, regardless of temperature variations.

Multizone isolation

The pressure compensation system perfectly fits intelligent completion with selective production from multiple zones. The packer will adapt to the changing environment along the well and reservoir’s life.
Qualified under ISO14310 V3 / API19OH V1 standards, the AZIP 1-1 can
seal annular sections in cased and open hole conditions. The packer can
hold up to 15,000 psi pressure reversals in HPHT environments.

Axial load

The packer also provides up to 200 klbs axial load capacity.
