The award-winning Hughes Christensen Kymera ™ hybrid bit by Baker Hughes combines PDC and roller cone bit technology for smoother drilling, remarkable torque management, and precise steerability. Leveraging the cutting superiority of PDCs in soft formations and the rock-crushing strength and stability of roller cones in hard or interbedded formations, the hybrid bit has the potential to maintain higher overall rate of penetration (ROP) for more footage than a roller cone or PDC could individually. A superior directional bit for motor and rotary applications, the Kymera hybrid bit provides increased buildup rate capabilities, dampened torque response, and precise steerability on a variety of bottomhole assemblies. The Kymera hybrid bit is improving drilling rates in tough applications worldwide. Within the U.S., it is successfully drilling interbedded and chert applications with single bit run lengths extended by more than 200%. In Brazil, it drilled 90% faster and 20% farther than offset bit performances. And in Iceland geothermal wells, it has proven to drill basalt sections more than twice as fast as premium roller-cone bits.

The award-winning Hughes Christensen Kymera™ hybrid bit by Baker Hughes combines PDC and roller cone bit technology for smoother drilling, remarkable torque management, and precise steerability.

Leveraging the cutting superiority of PDCs in soft formations and the rock-crushing strength and stability of roller cones in hard or interbedded formations, the hybrid bit has the potential to maintain higher overall rate of penetration (ROP) for more footage than a roller cone or PDC could individually.

A superior directional bit for motor and rotary applications, the Kymera hybrid bit provides increased buildup rate capabilities, dampened torque response, and precise steerability on a variety of bottomhole assemblies.

The Kymera hybrid bit is improving drilling rates in tough applications worldwide. Within the U.S., it is successfully drilling interbedded and chert applications with single bit run lengths extended by more than 200%. In Brazil, it drilled 90% faster and

20% farther than offset bit performances. And in Iceland geothermal wells, it has proven to drill basalt sections more than twice as fast as premium roller-cone bits.
