StayCool Multidimensional Cutter Technology

Beat the drilling day curve with cooler, sharper, more efficient cutter technology

Baker Hughes StayCool™ multidimensional cutter technology helps beat the drilling day curve and reduces drilling costs by minimizing friction on the cutter face, improving rates of penetration (ROP), and drilling more efficiently. Run on the Talon™ platform of high-efficiency PDC bits, StayCool cutters use unique nonplanar diamond table geometry and StaySharp™ polished cutter base technology to enhance performance in key applications. 

In more challenging environments like interbedded sandstones and carbonates, bit performance is directly related to cutter technology and its ability to withstand heat. Utilizing StayCool technology reduces heat generation at the cutter-rock interface. Cutter life is increased, which results in extended runs, fewer bit trips, and reduced overall time to reach total depth (TD). 

Stays cooler, runs more efficiently

Overheated cutters experience abrasive wear faster, which can lead to higher mechanical specific energy (MSE) or wasted energy that isn’t directly transferred into removing rock. StayCool cutters generate 50% less heat on the cutter face than conventional planar cutters while drilling in specific formations. This reduction allows the cutter to maintain a sharper edge for longer durations during a bit run. Reducing the heat generation on the cutter face also minimizes cracking and spalling tendencies that can lead to failures and shorten run life.

Maintains aggressiveness as it wears

The unique multidimensional geometry of StayCool cutters provides a degree of self-sharpening behavior as the cutter wears. Conventional planar cutters do not provide this benefit and simply become effectively duller as they wear. StayCool cutters dull more evenly and smoothly; thereby, maintaining aggressiveness of the cutters and allowing the bit to drill at higher ROP for longer duration during the bit run. 

Diamond mixes used in the manufacturing process enable the diamond structure in each StayCool cutter to be accurately tailored for each unique application. The result is a cutter with an exceptionally wear-resistant working surface, a sharper cutting edge, and a durable, impact-resistant supporting structure. For additional durability, StayCool cutters may incorporate an exclusive Baker Hughes diamond-layering process, combining an abrasion-resistant surface with additional diamond layers.
