AT-PP/Permanent Packer-well completion
ADD TO WISHLIST
Overview

AT-Permanent Packers feature the largest possible bore through combined packer and seal accessory. The AT-Permanent Packer is run to depth, connected to the tubing with a Model KC Anchor Tubing Seal Assembly, and is set by applied tubing pressure. This makes the packer ideal for use in high angle deviated wells common in offshore operations. The AT-Permanent Packers are designed to give maximum strength, uniformity of setting pressure and standardization of all alloy materials for H2S service.

Talk with anton expert
1. Solid, slim-line construction and a packing element system that resists swab-off. This provides a fast run-in time (when coMpared to earlier model permanent packers) without fear of iMpact damage or premature setting, yet packs off securely and permanently when the packer is set.

2. Two opposed sets of full-circle, full strength slips assure that the packer will stay where it is set.

3. Unique interlocked, expandable metal back-up rings contact the casing and create a positive barrier to packing element extrusion.

4. Safety of flanged up completions permits displacing tubing before setting packer.

Fracturing Hanger Packer Permanent Casing Hanger Up and Down Dual Slips-Well Completion
The hydraulic-set casing packer is a hydraulic permanent packer designed for the open-hole fracturing packer system, designed to hang the lower completion pipe in a string. The principle is to press inside the tubing, the thrust produced by the piston acts on the slips, and squeeze the packing element through the upper and lower cones. The upper and lower slips are broken and embedded in the inner wall of the casing, and the packing element expands and seals to complete the setting. At the same time, the locking ring inside the packer locks the setting force and maintains the setting of slips and packing element.
