Abstract
An apparatus for delivering a material into a wellbore comprises a body adapted to be translated along a conduit within a wellbore, with a cavity formed in the body for containing a material to be delivered. The body defines an outlet adapted to be selectively opened to permit the material to be released from the cavity at the required location within the wellbore. In one arrangement the material includes swellable particles which expand upon contact with an activator.
