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.
