1. KymeraTM Hybrid Bit Technology

2. KYMERA HYBRID BIT
Kymera is a combination of roller-cone design and polycrystalline diamond compact bit design (Rickard et.al 1).

3. GOAL
The reduction of drilling cost is crucial issue for geothermal operators and critical for long-term geothermal development.
In order to achieve this goal it is necessary to reduce drilling days and lowering per-foot costs
With this purpose, Baker Hughes, Inc. has developed the Kymera hybrid drilling bit

4. FEATURES AND BENEFITS
„„Rolling torque management with dual action cutting structures
Increases ROP potential
Reduces weight-on-bit requirements
Better directional control, more consistent and lower drilling torque
Reduces torsional vibration and axial vibration
„„Balanced downhole dynamics
Enhances stability, bit life, and drilling efficiency
„„Advanced roller cone bearing and seal package
Maximum seal reliability and longer bit life (Kymera Hybrid Drill Bits)

5. KymeraTM Hybrid Bit Technology Reduces Drilling Cost
Used in HP533X Kymera Hybrid Bits (Rickard et.al)
The results of Kymera Hybrid Bit Technology at Hudson Ranch Trials in Salton Sea (Rickard et.al)
Distance drilled by Kymera Bits comparing to average results (Rickard et.al)

6. Conclusion
By combining qualities of two types of bits into one component, Baker Haghes has created innovative product capable without reinventing the wheel (Dunnahoe 1).
The Kymera hybrid bit is capable of improving drilling rates in hard applications across the world (Kymera Hybrid Drill Bits).
There no more need to choose between ROP in durability (Terrel).

9. SUCCESS IN ICELAND
Baker Hughes assisted geothermal operator in Norway in exploration basalt sections (Kymera Hybrid Bit Drilled Twice as Fast …).
Two different sections were drilled in the geothermal test, 17.5-in. and in., (Dunnahoe).
The drill team have drilled the ft (173 m) in. section to T D of ft (270 m) demonstrating average ROP of 10.8 m/hr (35.4 ft/hr) that is almost three times faster than runs in offset wells (Kymera Hybrid Drill Bits).
With the Kymera hybrid bit a section of in was drilled to TD for a total distance of 1,597.8 ft (487 m). The average ROP constituted 21.3 m/hr (Kymera Hybrid Drill Bits).
