Abstract
An assembly for use in subsurface drilling includes a downhole probe supported in a drill string section by centralizing features that are integral with the drill string section. A bore wall of the drill string section is fluted to provide inward contact points that support the downhole probe. The downhole probe may be supported for substantially its entire length. A vibration damping and/or electrically insulating material may optionally be provided between the downhole probe and the drill string section.
