VR Safety joint is a compact, right-hand safety joint used in the drill stem testing string

5" VR Safety joint in stock
VR Safety joint is a compact, right-hand safety joint used in the drill stem testing string. It is run immediately above the packer assembly to ensure that a minimum number of tools are left in the hole if it becomes necessary to release the safety joint. The tool's bypass feature acts as an auxiliary to the Hydro spring tester bypass to allow fluid to pass though  the packer while the work string is being pulled out of the hole.

A spline and lug arrangement, joining the male and female parts of the left-hand safety joint thread, lock to prevent unintentional back-off from the tool during normal manipulation of the drill pipe during testing. Because of the spline and lug configuration, the slips must be dropped in place before the drill pipe is lowered after every stand of pipe is pulled out of the hole.
