Abstract: A logging tool includes a tool mandrel, an antenna disposed on the tool mandrel and including one or more coil windings wrapped about the tool mandrel, an antenna shield disposed about the antenna and including at least two pieces, and a constraining element to limit rotational motion of the antenna shield about the tool mandrel. The constraining element is disposed in a through hole defined in the antenna shield and a cavity defined in the tool mandrel, and the antenna shield and the tool mandrel are coupled to each other via an interference fit between the constraining element and the through hole and the cavity.

Abstract: An antenna assembly includes a first antenna section, a first housing section, a second antenna section, and a second housing section. The first antenna section includes a first antenna coil portion, and a first magnetic band disposed on the first antenna coil portion. The first housing section is configured to receive the first antenna coil portion and the first magnetic band. The second antenna section includes a second antenna coil portion, and a second magnetic band disposed on the second antenna coil portion. The second housing section is configured to receive the second antenna coil portion and the second magnetic band.

Abstract: A resistivity logging tool includes a resistivity antenna and an antenna shield having a longitudinal slot segments interconnected to form an elongated slot with an elongated slot length that is longer than the length of the sleeve in which the slot segments are formed thereby enhancing electromagnetic wave strength propagated through the shield. Longitudinal slot segments may be interleaved to maximize the total number of elongated slots.

Abstract: A loop antenna assembly is provided that can include a loop antenna with one of more magnet wires encased in a non-magnetic flexible sheath and mounted to a transceiver block that is mountable to a tool body, where the loop antenna can at least partially encircle the tool body. The loop antenna can include a plurality of magnet wires each individually encased in the sheath, with a metal adaptor attached to each end. The magnet wire can be coated with thin insulation, thin enamel insulation, and/or a polymer film. A plane of the loop antenna can be perpendicular relative to the longitudinal axis or at an obtuse angle relative to the longitudinal axis. A non-magnetic locating ring positioned in the loop antenna assembly can secure the loop antenna of the assembly about the tool body.

Abstract: Pre-formed non-flexible antenna modules are connected to one another via radio-frequency (“RF”) connectors for downhole applications. The antennas include two or more non-flexible antenna modules having a one or more center conductors extending therethrough. The antenna modules are connected by high frequency RF connectors, thereby forming a single antenna. Accordingly, the illustrative embodiments described herein will reduce the assembly complexity, increase repeatability of the design implementation, and enhance the productivity of the manufacturing process.
