Abstract

A string from the surface is connected to a packer extension with a thread to provide a metal to metal seal for production or injection through the packer. The thread provides a metal to metal seal. The initial string is released from the packer extension by a tubular cut made with a cutting tool above the thread that provides the metal to metal seal to the packer extension. An outer sleeve surrounds an expanded length of wall which is the target cut zone above the threaded connection. A cut through the tubular does not cut the outer sleeve. The outer sleeve features a left handed square thread to engage a known released tool run in on a string to connect to the packer release mechanism and release the packer for removal with the release tool suspended from a string.
