Locator Seal Assembly
The Locator Seal Assembly is used when it is not desirable to anchor the seals into the packer. The Locator Seal Assembly allows movement of the seals in response to pressure and temperature changes on the tubing string. Force changes tending to elongate the tubing string are transferred through the locator into the packer and casing. Seals are dynamic and must be designed to accommodate sliding or reciprocation, in addition to temperature and wellbore fluids. The Locator Seal Assembly is retrieved by straight pick-up.
Anchor Seal Assembly
Anchor Seal Assemblies lock, or anchor, into the packer top and seal in the bore of the packer or seal bore extension below the packer. The anchor seal assembly transfers tubing forces through the anchor into the packer; the seals are static and are only subjected to pressure differentials.
Travel Joints
Travel Joints are made up in the tubing string and run into the well with packers and other down hole flow control equipments, and provide alternate methods of compensating for tubing contraction and elongation in producing, injection, and disposal wells. The travel joint are pinned in the closed, mid, or extended position before running. They also are keyed to prevent future rotation. The joints without keys are used when tubing torque below the joint is not required.
Seal Bore Extension & Mill Out Extension
The Seal Bore Extension are generally used in installations where floating seals are required due to excessive tubing contraction. The Seal Bore Extensions have the same sealing bore ID as the corresponding packer to allows a continuous seal bore for the lower most seals of a long seal assembly. The Seal Bore Extensions are available in a variety of lengths.
