Swellable Member, Swell Controlling Arrangement and Method of Controlling Swelling of a Swellable Member

摘要

A swell controlling arrangement includes a swellable member configured to swell upon exposure to a swell inducing fluid, and an acidic material that is configured to form an acidic environment. The swell controlling arrangement is configured to preferentially expose the swellable member to the acidic environment when the swellable member and the acidic material are exposed to the swell inducing fluid.
