Abstract

An apparatus (10) for mounting on a tubular (12) for location in a bore comprises a seal comprising a swelling sealing material adapted to permit passage of fluid cement between the tubular and the surrounding bore wall which is void of set cement. Alternatively, the sealing material may expand into a space between the tubular and surrounding set cement.
