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.
