Detailed Product Description:
This tool is the only drilling tool that adds a torsional impact directly to the drill bit. Just like an impact driver, the tool converts hydraulic energy into torsional hammering action that enables aggressive PDC bits to fracture and drill through even the hardest rock at higher depths of cut. Also, failing the rock more frequently prevents stick-slip, a destructive process where torsional energy is cyclically stored up and released from the drill string. That means that not only do you drill faster, but your bit and BHA stay drilling longer.
The phenomenon of stick-slip is well researched and documented within the drilling industry. Bit-related stick-slip is often a problem when drilling hard formations with a Polycrystalline Diamond Compact (PDC) fixed-cutter bit. Under optimum drilling conditions, the PDC bit shears formation with a constant depth of cut (DOC). When a harder formation is encountered the bit loses DOC and more weight-on-bit (WOB) must be added to engage the PDC cutters in formation. Many times, however, the reactive torque of the formation cannot be overcome immediately - in this case the bit slows or stops (stick) while torque is stored in the drill string until the torque required to fail formation is achieved and the bit violently rotates (slip). This action can cause damage to PDC cutters and other drill string components, resulting in reduced bit and tool life as well as poor rate of penetration (ROP).
Traditional methods for mitigating stick-slip involve adjusting operating parameters to avoid the stick-slip phase, pacifying the PDC bit by using higher blade counts, higher backrakes, etc., or even by using less-efficient roller cone or diamond-impregnated bits. These methods have only been marginally successful and reduce overall drilling efficiency and lead to reduced potential ROP.
