Abstract: A system can be used to control shock applied to a downhole tool. The system can include an internal component, an outer component, and a wedge pin. The internal component can be positioned in the downhole tool. The internal component can include an axial shoulder and an angled seating surface. The outer component can be positioned in the downhole tool. The outer component can include (i) an opening sized to receive a preload cap, and (ii) a flange positionable to contact the axial shoulder. The wedge pin can be positioned in the opening and abutting the angled seating surface to apply a preload to the internal component and the outer component in response to the preload cap being positioned in the opening.

Abstract: Logging downhole exposes components of logging tools, for example, antennas to abrasive and erosive operating conditions. A protective sleeve may disposed about an antenna assembly to protect the antenna assembly for the downhole operating conditions. To permit transmission and receipt of signals by and too the antenna assembly, slots are formed or disposed in the protective sleeve. A non-conductive composite insert is formed in the slots to protect the internal components of the protective sleeve, for example, the antenna assembly, from the operation conditions. A non-conductive composite inner liner is formed in an annulus of the protective sleeve and adheres to the protective sleeve and the non-conductive composite insert. The non-conductive component insert and inner liner allow signals to be transmitted and received by the antenna assembly so that logging operations can be completed without undue delay and the expense of repairing or replacing worn or damaged components.

Abstract: A tool that uses antennas to evaluate an environment surrounding a wellbore, where the tool can include a sleeve with an antenna mounted thereon, and the antenna including a ferrite assembly and a coil assembly, where the coil assembly can be mounted radially outward from the ferrite assembly, and the coil assembly can transmit electromagnetic signals into the environment and/or receive the electromagnetic signals from the environment. The electromagnetic signals can be evaluated to determine one or more parameters of the environment surrounding the wellbore. The tool can include one or more grooves disposed in a wall of a sleeve of the ferrite assembly, with one or more ferrite objects installed in the grooves, with a cross-sectional shape that can retain the ferrite objects in the groove. The ferrite objects can alter a trajectory of one or more of the electromagnetic signals.

Abstract: A drilling tool system includes a drilling tool collar having at least one recess and a sleeve disposed around the drilling tool collar, wherein the sleeve comprises at least one slot configured to align with the at least one recess. The drilling tool system further includes an inner key disposed within the at least one recess, an outer key secured within the at least one slot and at least partially disposed within the at least one recess, and at least one fastener configured to drive the inner key in a first lateral direction and the outer key in a second lateral direction to secure the inner key against a first lateral surface and the outer key against a second lateral surface, and wherein securing the inner key and the outer key restrains rotational movement of the sleeve with respect to the tool collar.
