Abstract
A production sting has a premium thread preferably VAM or similar for threading into a packer extension without the need for a seal stack to engage a seal bore in the extension. The seal bore use becomes optional and a metal to metal seal is provided by the premium thread whether the string is in compression or tension. Another adjacent left hand square thread is provided in the packer extension to land accessory tools or for removal of the packer after the packer is released in a variety of known ways. Either the premium thread or the left hand thread can be in the uphole position on the packer extension.
