ABSTRACT:
A ring member for a downhole apparatus includes a swellable material selected to increase in volume on exposure to at least one triggering fluid. The ring member is configured to cooperate with a swellable member disposed on a body of the apparatus, and may function as a gauge ring or a retaining member. The ring member is secured to the apparatus via a coupling arrangement which couples the body to an adjacent well string section. The ring member may be threaded into the well string. Alternately, the ring member may be disposed over an upstanding formation such as a coupling sleeve by clamping.
