seen the tapered thread often - clever and simple idea, did anyone patent it?

yes, I can see the the second scenario - joint findings it's way back down.

tks for the info and expertise.

Hi ct
well the the pipe thread is tapered and only engages tightly at the end of its makeup so only needs a little disengagement to be completely free to drop  free of the one its connected to and there would be a set of pipe rams in the BOP which wouldn't allow it though to the open hole, another way might have been that they were getting ready to set a triple back as the well blew out the pipe in the hole would have lifted the slips clear of the rotary table and the joint that was being set back was let go by the derrickman and it found its way back down the well which seems feasible to me assuming that they were in the process of pulling the drill string out of the hole
