Abstract
Provided is a sealing/anchoring element, a sealing/anchoring tool, a well system, and a method for sealing/anchoring within a wellbore. The sealing/anchoring element, in one aspect, includes a circlet having an inside surface having an inside diameter (di), an outside surface having an outside diameter (do), a width (w), and a wall thickness (t), the circlet having one or more geometric features that allow it to mechanically deform when moved from a radially reduced mechanical state to a radially enlarged mechanical state, the circlet comprising an expandable metal configured to expand in response to hydrolysis to chemically deform the circlet from a radially reduced chemical state to a radially enlarged chemical state.
