The drilling industry has enjoyed the benefits of hybrid drill bits for nearly 10 years. Pairing the fixed blades of a polycrystalline-diamond-compact (PDC) bit with the roller cones of a tricone bit, hybrid bits crush the rock and then shear it away, minimizing downhole vibrations. Baker Hughes, a GE company, recently introduced the Kymera Mach 4 hybrid drill bit, designed to extend drilling lengths to handle combination sections, saving trips and replacing both roller-cone and PDC bit runs. The bit features reinforced shoulder durability that improves previous hybrid-bit designs. Recessed cutters and increased blade counts keep the bit engaged, extend bearing life, and deliver up to 25% greater rates of penetration compared with previous hybrid-bit designs while improving borehole quality. Upgraded PDC cutters are designed to handle the increased stress load of challenging drilling environments.
