  • Apparatuses and methods relating to cooling a subterranean drill bit and/or at least one cutting element during use
    Patent number: 8783380
    Abstract: One aspect of the instant disclosure relates to a subterranean drilling assembly comprising a subterranean drill bit and a sub apparatus coupled to the drill bit. Further, the sub apparatus may include at least one cooling system configured to cool at least a portion of the drill bit. For example, the sub apparatus may include at least one cooling system comprising a plurality of refrigeration coils or at least one thermoelectric device. In another embodiment a subterranean drill bit may include at least one cooling system positioned at least partially within the subterranean drill bit. Also, a sub apparatus or subterranean drill bit may be configured to cool drilling fluid communicated through at least one bore of a subterranean drill bit and avoiding cooling drilling fluid communicated through at least another bore of the subterranean drill bit. Methods of operating a subterranean drill bit are disclosed.

  • Superabrasive compact with selected interface and rotary drill bit including same
    Patent number: 7757790
    Abstract: A superabrasive compact including a superabrasive layer bonded to a substrate along a selected interface is disclosed. In one embodiment, an interface may comprise a depression and a dividing wall, wherein the dividing wall forms at least one closed plane figure. In another embodiment, an interface may comprise a depression, a dividing wall forming at least one closed plane figure, and at least one raised feature positioned within the depression. In a further embodiment, an interface may comprise a depression formed into the substrate, the depression surrounded by a closed peripheral wall exhibiting a thickness of about 0.080 inches or less. A rotary drill bit including at least one cutting element is also disclosed.
