Since launching the original Kymera hybrid drill bit in 2011, Baker Hughes, a GE company, has been expanding the bit’s capabilities. The latest iteration, the Kymera Mach 4, was launched in early 2018 and has been designed to drill every section of the well at a high rate of penetration (ROP) with low wear and tear. BHGE increased the blade count on the bit, to improve lateral stability and reduce damage and wear on the bit, Shelly Cory, Kymera Product Line Manager, explains in this video from 6 March at the 2018 IADC/SPE Drilling Conference in Fort Worth, Texas. She also discusses how new recessed cutters help improve cuttings evacuation and contribute to extended bit life. Further, she outlines how the bit has enabled increased ROPs and saved bit runs in Oman and the Permian.
