Provide a larger ID below series packers to
protect the seals and to accept the packer
retrieving sub of a milling tool
Mill-out extension is used when floating seals are required
in completion using seal-bore packer series. Mill-out
extensions provide a larger ID below the packer to protect
the seals. The larger ID is also useful when a packer milling
and retrieving tool is employed. The extension ID must be
greater than the packer ID to furnish an adequate shoulder
for retrieving the packer after the milling procedure is
completed. Extensions are assembled onto the lower end of
the millable seal-bore packer and run into the hole.
KSA mill-out extensions are supplied on a box-by-box
configuration in 6 ft length.
