Abstract: A system to protect a downhole antenna from fluid penetration, in some embodiments, comprises a collar; a bobbin antenna, mounted on the collar, including multiple coil slots on an outer surface of the bobbin antenna and including one or more intra-bobbin wireways between at least one of the coil slots and an outlet of the bobbin antenna; and a collar wireway that is dedicated to the bobbin antenna.

Abstract: A collar-mountable antenna for transmitting and receiving signals in a downhole environment, in at least some embodiments, comprises a bobbin having an inner surface and an outer surface, each of the inner and outer surfaces defining multiple slots, conductive wire disposed within the multiple slots on the outer surface of the bobbin, and ferrite disposed within the multiple slots on the inner surface of the bobbin.

Abstract: Systems and methods for drilling operations may use encapsulated explosives to complement the performance of downhole cutting tools. An exemplary method may include drilling a wellbore penetrating a subterranean formation with a downhole cutting tool; circulating a drilling fluid in the wellbore, wherein the drilling fluid comprises a base fluid and an encapsulated explosive having an average diameter of about 10 nm to about 20 microns; triggering detonation of the encapsulated explosive; and detonating the encapsulated explosive proximal to a portion of the subterranean formation adjacent the downhole cutting tool.
