Abstract
Embodiments may generally take the form of a safety joint and methods related thereto. One embodiment may take the form of a safety joint deployable in a well. The safety joint includes a first sub and a second sub coupled to the first sub. The coupling of the two subs may include a first set of threads having a first orientation and a second set of threads having a second orientation different from the first set of threads. The first sub is decoupleable from the second sub upon disengagement of the first set of threads by rotation in a first direction followed by disengagement of the second set of threads by rotation in a direction opposite from the first direction.
