Baker Hughes Incorporated announced yesterday 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.

“Our customers are demanding more from their drilling equipment than ever before. They are drilling through harder formations and interbedded sections using more horsepower, more torque and higher weight-on-bit,” said Scott Schmidt, Vice President, Drill Bits at Baker Hughes. “Unfortunately, this often leads to excessive downhole vibrations, premature cutter breakdown, damage to the bit body itself or some combination of the three, and that it turn leads to unplanned trips. In high-cost applications, or over the course of a drilling campaign, these trip costs, or even the cost of drilling ahead with a damaged bit or BHA, can add up to millions of dollars.”
