A New Solution to Active Torque
RipSaw™ is the ultimate solution for smooth torque through transitional formations and unconventional laterals. RipSaw’s Active Torque Technology™ controls depth of cut and torque fluctuations without limiting ROP.
Drilling with a PDC bit requires smooth and consistent engagement to maximize efficiency, reduce dysfunction, and improve performance. In real drilling environments, where down hole conditions are constantly changing, this balance is very hard to achieve.
Rather than simply limiting bit performance with secondary features, Ulterra engineers devised a better way. RipSaw engages changing rock properties and drilling parameters using active torque technology that smooths torque oscillations with the active cutting structure.
What is Active Torque Technology?
Active torque means that the solution is both active across the drill bit’s entire range of depth of cut and is also part of the active cutting structure. Rather than using passive, secondary elements, RipSaw uses active cutting elements incorporated into the primary cutting structure to deliver a manageable torque response across the entire operating range of the bit.
The Torque Advantage
- Instantaneous, active damping of drilling forces
- Active DOC control across the bit’s entire operating range
- No hard stop fixed elements which limit ROP
- No moving parts, no additional risk
Get these RipSaw Advantages
- Increased durability without sacrificing ROP
- Smoother torque response delivers more stability and control
- Opens up useable parameter window so you can push the bit harder
- Consistent reaction to changes in depth of cut
A New Approach to an Old Problem
When blade geometry is used to limit depth of cut the material can wear down, meaning that the intended depth of cut is only good for a short time.
Many DOC features are replaced between runs. This adds manufacturing tolerance and requires wider blades, which can limit hydraulics and bit cleaning.
More recent attempts to solve this problem have added the significant complexity of moving parts that can fail and cause junk in hole risk.
