Seal Assemblies (Locator, Anchor, Latch)
Used with permanent type packers to provide isolation between the producing zone and the annular space above the packer when the tubing is located into the packer.
The seal assemblies are designed with external seals on the tubing which pack-off in the polished bore of the packer or a packer extension (used to retain the same packer bore diameter as the tubing). Basic seal units include two seal stacks, but any number of seal units can be screwed together to increase the length of the assemblies.
