National Oilwell Varco (NOV) introduced the ION application-specific polycrystalline diamond compact (PDC) cutter technology into its Tektonic drill-bit line. ION cutters consist of a range of PDC cutter technologies that are designed to overcome critical failure modes within specific applications globally. ION PDC cutters use refined diamond feeds with increased sintering pressures to provide denser diamond with high toughness and high abrasion resistance. Thermal stability is enhanced, further using ReedHycalog’s patented deep-leach technology. Included in the range is the ION 3D-shaped cutter technology, which features a durable pointed cutting-edge that greatly increases drilling efficiency and makes possible rate-of-penetration (ROP) increases of greater than 20% for the same weight on bit. Proprietary software is used for designing cutting structures that incorporate placement and orientation of both ION 3D-shaped and ION round PDC-cutter technology. The technology also incorporates a polished mirror finish that reduces friction on the cutting face of the cutter, which increases ROP, improves efficiency, and reduces cutter temperature to avoid thermal degradation.
