A wellbore formation system includes a downhole cutting tool having a body and at least one cutting element. A sensor is coupled to the downhole cutting tool, and the sensor includes a transmitter configured to transmit a signal prior to wear on a portion of the downhole cutting tool reaching a first amount. The sensor ceases transmission of the signal when the wear on the portion of the downhole cutting tool reaches the first amount.

Downhole cutting tool having sensors or releasable particles to monitor wear or damage to the tool

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.

Dedicated wireways for collar-mounted bobbin antennas

Mechanisms for induction-based resistivity measurements can be provided for use in geo-steering in a drilling operations environment. An antenna assembly can provide effective protection for antenna sections without hindering propagation of electromagnetic signals. The antenna assembly can include a bobbin disposed about a collar of a tool string; an antenna disposed on an outer surface of the bobbin; an outer adhesive layer covering the antenna and at least a portion of the bobbin; and a protective layer disposed against the outer adhesive layer; wherein the outer adhesive layer fills a space radially between the bobbin and the protective layer.

Buildup and encapsulation of antenna section of downhole tool

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.

Collar-mountable bobbin antenna having coil and ferrite slots

Disclosed is an apparatus and method for shearing well drilling fluid mixtures containing an emulsifier, and utilizing pumping the fluids through a plurality of nozzles, reducing the size of the fluid droplets as they pass through the nozzles, discharging the fluid droplets into a output chamber where the emulsifier surrounds the smaller droplets with the nozzle discharges aligned to intersect in the stabilization chamber.
