High-pressure drill bits are designed for use in HP/HT wells, deepwater drilling, and unconventional plays where high bottom-hole pressures and temperatures demand robust cutting structures and hydraulics. Production has grown steadily over the past decade, in line with complex well drilling in shale basins, deepwater fields, and challenging onshore reservoirs. Major drill bit manufacturers have invested heavily in PDC (polycrystalline diamond compact) technology, improved cutter geometries, erosion-resistant matrix bodies, and enhanced nozzle designs for high-pressure mud systems.
