Patent number: 10698127Abstract: An antenna shield latches around a mandrel or wellbore tubular to protect an antenna carried by the mandrel. The antenna shield opens to facilitate installation over the mandrel, and closes the around the antenna to provide robust protection from the downhole environment. Radial sections of the antenna shield are coupled to one another such that the antenna shield maintains a one piece construction, and the sections may pivot to move the antenna shield between open and closed configurations. Readily opening and closing the antenna shield facilitates maintenance and repair of the antenna and reusability of the antenna shield. Other components of a logging tool system, e.g., stabilizers, may also be provided with a similar latch mechanism for coupling to an outer diameter of the wellbore tubular.Type: GrantFiled: January 30, 2018Date of Patent: June 30, 2020Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Heen Wei Ng, Minh Dang Nguyen
