By isolating vibration from the bottom hole assembly, caused by the drilling operations, the shock tool reduces the probability of the drill string or/and electronic components failure due to fatigue destruction.
SDT-ST shock tool design ensures efficient operation under various combinations of drilling parameters and reduces fluctuation/spikes in mud flow rates and pressure.
Downhole shock tool SDT-ST can be installed in the BHA directly above the bottom hole drive or above it.
