20120024600 | Method and Apparatus for Resistivity Measurements - An apparatus for measuring a resistivity of a formation comprising an instrumented bit assembly coupled to a bottom end of the apparatus. At least one first electromagnetic wave antenna transmits an electromagnetic wave signal into the formation. At least one second electromagnetic wave antenna located on the instrumented bit assembly and longitudinally spaced apart from the at least one first electromagnetic wave antenna receives the electromagnetic wave signal transmitted through the formation. Electronic circuitry is operably coupled to the at least one second electromagnetic wave antenna to process the received signal to determine a resistivity of the formation proximate the instrumented bit assembly. | 02-02-2012 |

20140083773 | Reliability for Electromagnetic Data Telemetry for Downhole Application on Well Drilling Operations - A tool and associated methods for transmitting electromagnetic data telemetry from a downhole sensor during drilling operations. The tool may include a pressure housing, the pressure housing including an EM transmitter, receiver, or transceiver. A conductive element electrically coupled to the EM transmitter, receiver, or transceiver is positioned between an upper and a lower signal conductor positioned coaxially around the conductive element. The upper and lower signal conductors support the pressure housing and conductive element within the inner diameter of a drill collar and provide electrical connection between the conductive element and a section of the drill collar on either side of an insulated gap. In some embodiments, the conductive element is tensioned between the upper and lower signal conductors. | 03-27-2014 |

20090309798 | Method and Apparatus for Building a Tilted Antenna - Logging tools having protected tilted antennas are disclosed, along with construction methods therefor. In one method embodiment, a tilted antenna on a retrievable segment of a downhole tool is constructed by: forming an elliptical recess on the segment; forming an antenna within the elliptical recess; and forming an elliptical pattern of windows over and perpendicular to the axis of the elliptical antenna. Some tool embodiments comprise a retrievable segment of a downhole tool having an elliptical recess; an elliptical antenna disposed within the elliptical recess; and an elliptical pattern of windows formed over and perpendicular to the plane of the elliptical antenna. | 12-17-2009 |
