Abstract
An apparatus for supporting a retrievable downhole component within a drill collar includes a sleeve that is positionable about the downhole component and is mounted within the drill collar. The sleeve is adapted to limit the lateral movement of the downhole component. The sleeve includes a series of fins or is lined with an energy absorbing material which protects the component from shock and vibration while at the same time enables the component to be retrieved should the drill string become stuck in the borehole.
