Abstract

Expandable seal members or inserts are included as part of fluid activated downhole tools such as packers and liner hangers. The expandable seal inserts comprise one or more expandable materials that expand and seal against the chamber carrying the actuator of the downhole tool. Fluid flowing in the downhole tool to actuate and, thus, set the downhole tool, also causes the expandable seal inserts to expand. In so doing, the expandable seal inserts provide seals, some redundant to dynamic seals and static seals already present in the downhole tool, to assist in preventing leaks in the downhole tool that may otherwise cause the downhole tool to fail.
