摘要：
A downhole sealing element includes, a malleable member having at least one closed wall cavity therein positionable downhole in a gap defined between downhole members, and a chemical disposed within the at least one closed wall cavity. The malleable member is deformable to fill variations in a dimension of the gap and the chemical is reactive to form a nonflowable element.
