The Tension Safety Joint is a two-stage emergency disconnect tool that can be used to mechanically separate the drill string in a controlled way. If the string is stuck at a packer or elsewhere, it can be operated to recover tools above the Safety Joint. The lower half of the safety joint that is left down hole provides a connection for fishing tools.
