NOV Introduces ION+ Intrepid: Advancing PDC Cutter Performance and Durability

Closing the Gap: New Cutter Sizes for New Possibilities

For decades, fixed-cutter bit designs have relied on conventional cutter diameters-typically 8 mm, 13 mm, 16 mm, 19 mm, and larger. While effective, these size increments left limited room for optimization in applications where mechanical efficiency, rate of penetration (ROP), or durability could be improved with more precise cutter selection.

ION+ Intrepid fills this gap with the introduction of 14.5 mm and 17.76 mm cutters, strategically positioned to provide bit designers greater flexibility in optimizing cutter layouts, spacing, and exposure. Further advancements are reached by leveraging ReedHycalog's proprietary modeling software, enabling engineers to optimize cutter distribution, exposure, and bit layout to extract maximum mechanical advantage from these new sizes. As a result, ReedHycalog™ Evolve performance drill bit designs fine-tune to achieve increased ROP without compromising steerability or structural integrity.

Technology-Driven Design for Real-World Impact

Leveraging ReedHycalog's proprietary modeling software, engineers can optimize cutter distribution, exposure, and bit layout to extract maximum mechanical advantage from these new sizes. The result is a portfolio of drill bits capable of achieving higher ROP, improved durability, and enhanced performance across a wide range of lithologies and operational challenges.

Innovation Backed by Field-Proven Performance

This technology has demonstrated significant potential, not only in North American unconventional drilling, but also for global drilling environments where operators seek improved efficiency, reduced non-productive time (NPT), and lower overall drilling costs.

The development of the 14.5 mm cutter size can be coupled with ReedHycalog's advanced geometries to further enhance cuttings evacuation and reduce reactive forces on the bit-key factors in maintaining stable drilling mechanics. Early field deployments have validated the potential of the technology.

In a high-performance 6-in. Bakken lateral drilling application, a new drill bit featuring the 14.5 mm cutters delivered (SPE-230691-MS):

• 15-20% average ROP increase, with peak improvements above 25%

• Smoother, more stable drilling with reduced vibration

• Improved directional control and tool-face management

• Exceptional durability, with minimal wear and strong re-run potential

• A record-setting 2-mile lateral, the fastest ever drilled for the operator

Across multiple well trials, the bit consistently outperformed offsets drilled with traditional 13 mm and 16 mm cutters-proving not only its efficiency but also its resilience in abrasive formations such as the Bakken. In the Permian, ION+ Intrepid delivered double the average interval drilled in a third Bone curve-lateral, exceeded the average ROP by 20%, and had an above average dull condition. In Egypt, Intrepid outperformed two competitor technologies with 60% improved ROP over the best offset.

Redefining the Future of Cutter Technology

ION+ Intrepid represents the next evolution in ReedHycalog's cutter technology. By rethinking cutter sizes and shapes-and validating their impact through rigorous field testing-NOV is delivering solutions that help operators drill farther, faster, and more reliably than ever before.
