BAKER HUGHES RELEASES DYNAMUS EXTENDED-LIFE PDC DRILL BIT
Baker Hughes Incorporated announced today the commercial release of its Dynamus extended-life polycrystalline diamond compact (PDC) drill bit which can significantly reduce drilling costs by eliminating trips to replace bits or bottomhole assembly (BHA) tools that wear out in high horsepower drilling operations. The Dynamus bit is built on a robust frame that incorporates stabilizing elements to prevent lateral vibrations as well as proprietary cutters engineered to minimize wear. Reducing vibrations not only extends bit life, it also helps extend the life of other BHA tools and deliver smoother drilling performance for improved borehole quality. The Dynamus bit is built on a new, robust frame that incorporates stabilizing elements to prevent lateral vibrations as well as proprietary cutters engineered to minimize wear.
The Dynamus bit includes StayTrue shaped diamond insert elements which stabilize the bit to reduce lateral vibrations by more than 90 percent mitigating vibration-induced damage to both the bit and highly sensitive BHA components containing electronics. The bit’s long-life StayCoo 2.0 cutters deliver superior performance across a wide-range of formation types by generating 30 percent less heat than standard PDC cutters. This reduces wear and premature weakening of the cutters that is often a result of excessive heat generation.
The Dynamus bit’s elements and cutters are incorporated into a newly designed body comprised of an extremely tough matrix material that resists cracking and is capable of handling extreme operating loads that would damage conventional PDC bits. A new, holistic Finite Element Analysis (FEA) protocol was developed and implemented during the design phase to accurately predict the Dynamus bit’s reaction to real-world forces.
