Vibrations in the drilling BHA are the main cause of tool failure that result in early pull out of the drilling assembly.
There are two types of vibrations. Lateral vibrations create oscillatory movements, forcing drill string components to swing inside the borehole. There are also axial vibrations, which make the drill string ‘bounce’ up and down, affecting the entire BHA. These vibrations can be powerful, causing tool failures, especially for the electronic components of downhole measurement tools.
NeoTork is designed to also act as a ‘shock absorber’ to protect downhole components. When vertical vibrations occur, the disc springs in the top of the tool contract, absorbing the vertical energy from the drill string before it is transmitted to the drilling BHA. This reduces the incidences of tool failure. Fewer premature pull outs, means lower drilling costs.
