The compression set liner Top packer that utilizes the High-Performance Packing Element design. The Packing element is actuated by applying set-down weight to the tieback extension via the setting dogs on the liner setting tool. This setting force drives a cone under the Slip causing it to expand and conform to the casing ID. The packing element will squeeze and seal off any extrusion gap, a body lock ring system holds a permanent set in the seal once actuated. The packer will provide an effective annular seal between the top of the liner and the casing, thus preventing possible formation breakdown, loss of cement slurry and gas migration above the liner top during cement cure. Hold down slips are available to prevent upward movement of the liner and suitable for horizontal wells. The Liner Hanger System has integral setting collar to rotate the Liner Hanger during running in and cementing.
