Donwhole Testing RTTS Safety Joint APR DST Tools


The full bore retrievable safety joint is an emergency backoff device, which is named RTTS safety joint 

in Halliburton type. The purpose of the safety joint is to provide a disconnect point in the tool string 

above the packer for removal of all equipment above that point if the work string becomes stuck and the 

Safety Joint can still be operated. The safety joint can be installed on the top of RTTS circulating vale 

as well as between the RTTS circulating valve and RTTS packer.  By a tension sleeve located on the 

bottom of the mandrel the RTTS Safety Joint is held inoperative to help prevent premature release.
