    National Oilwell Varco has introduced ReedHycalog Helios Thermal Tough Cutters, a range of thermally abrasion-resistant PDC cutters that have been re-engineered from the ground up. This technology has been designed specifically for material with NOV’s deep leach technology to significantly reduce cutter degradation and allow the bit to drill farther and faster. The entire cutter-rock interaction has been studied and finite element analysis has been employed to provide a more complete, durable rock-cutting solution. Since putting this new technology into effect, engineers have been able to significantly improve overall bit performance, in many cases enabling operators to reach TD with one bit. Numerous bit runs have proven successful in the Bakken, Haynesville and Barnett shale plays as well as challenging applications in the Middle East. The cutters have achieved 194% increases in the average footage drilled and over 100% increases in penetration rate. In some cases, 52% decreases in cost per foot have been realized.
