PileDRIVER 
While drilling ahead in vertical hole sections, there are significant challenges to overcome such as stalling, stick/slip and high shock and vibrations.
The DWS PileDRIVER helps to prevent these issues by autonomously mitigating extreme weight on bit and pressure events using an internal hydraulic compensation mechanism as well as a robust mechanical dampening system.
Features
Optimizes drilling performance
Increases ROP by providing consistent weight on bit
Extends life of both motor and bit by mitigating differential and WOB spikes
Decreases risk of damage to MWD by substantially dampening excessive shock and vibration
Fully mechanical design is completely manufactured in-house
12 inch stroke length allows tool to be ran within a wide range of WOB and motor parameters
Proprietary hydraulic compensation system
Potential to reuse across multiple wells
