The ThermoBlade™ thermal-resistant diamond element bit saves customers drilling time and reduces the need for costly bit trips. These bits use thermal-resistant diamond cutting elements that effectively mitigate the effects of thermal degradation—cracking and chipping of the cutter surface—to increase durability, extend bit life, and improve overall bit performance for both oil and gas and geothermal wells.

• Conventional and unconventional land in Canada, Middle East, and US
• Offshore Gulf of Mexico
• Hard and abrasive formations
• Geothermal drilling

• Lowers drilling time
• Reduces costly bit trips
• Mitigates effects of thermal degradation (cutter cracking and chipping)
• Extends bit life
• Improves overall bit performance

蘑菇传媒 developed the new ThermoBlade bit using a proprietary cutting element with a thicker diamond table and engineered diamond table interface. The interface provides this cutting element with mechanical strength and durability. The cutting element also has a novel thermal stability against the tremendous heat that can approach 1,000 degC [1,832 degF] and shearing forces concentrated on the tip. This combination gives the ThermoBlade bit better resistance to thermal degradation that causes cutter damage on other drill bits. These features improve drillbit ROP and its ability to drill to interval TD in fewer or single bit runs.

Performance Enhancements

Scribed thermal-resistant diamond cutting element
The scribed thermal-resistant diamond cutting element enhances ROP by creating controlled stress points that reduce friction and improve rock engagement. This innovation delivers up to 19% better cutting efficiency while maintaining cutter sharpness throughout the drilling interval.

Engineered for durability, the scribed cutter features a thicker diamond table and an optimized leaching profile, providing 20% greater wear resistance compared to conventional flat, round-shaped PDC cutters*. Its advanced thermal-resistant cutter technology incorporates a high-conductivity carbide substrate, which efficiently dissipates heat to prevent thermal degradation and extend cutter life.

This enhanced resilience, combined with optimized force distribution, reduces bit trips and improves operational uptime. Designed to work seamlessly with any bit design, the scribed cutter boosts ROP while maintaining directional control. It is particularly effective in medium-to-hard interbedded layers, abrasive rock zones, and mixed lithologies, where performance and reliability are critical.

Ultrathermal-resistant diamond cutting element
The ultrathermal-resistant diamond cutting element extends drilling intervals by maintaining cutter sharpness. With 17% more diamond volume, advanced leaching technology, and a proprietary high thermal conductivity bilayer carbide, this technology efficiently transfers heat away from the cutting tip. This keeps the diamond table cooler, enhancing mechanical durability.

The cutter achieves a 23-degC reduction in cutting tip temperature**, effectively preserving sharpness by minimizing thermal degradation. This improvement enables up to 56% longer drilling intervals compared to conventional thermal-resistant cutters.*
