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.
