Abstract: 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.

Abstract: 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 senor 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.
Abstract translation: 井筒形成系统包括具有主体和至少一个切割元件的井下切割工具。 传感器联接到井下切割工具，并且传感器包括发射器，其被配置为在磨损前在井下切削工具的一部分上传送信号达到第一量。 当井下切削工具部分的磨损达到第一量时，传感器停止信号传输。
