Blind Back-off Procedure

Esteemed Forum Members,

I was wondering if any of you would have a (proven) detailed procedure, that you could share, to perform a blind back-off using a TDS rig. Assume the BHA is stuck.

Particularly interested to see procedures to perform a blind back-off using a combination string (for example 3-1/2" and 5" drill pipe) in a deviated well with the objective to back-off the 3-1/2" drill pipe.

Many thanks in advance.

Harald Benning.
