Claim 8:
9. A system for cementing in a wellbore comprising:
a conduit disposed in the wellbore;
a reactive metal element disposed on the exterior of the conduit, the reactive metal element comprising a reactive metal having a first volume, wherein the reactive metal element is disposed between a pair of retaining elements which are disposed on the conduit, wherein a spacer element is disposed on the conduit on each of the opposing sides of the retaining elements relative to the reactive metal element, and wherein the spacer elements are outside of the retaining elements relative to the reactive metal element; wherein the retaining elements are cup seals, end rings, or stamped rings; wherein the spacer elements comprises a polymer-based material;
a reaction-inducing fluid capable of reacting with the reactive metal to produce a reaction product having a second volume that is greater than the first volume; and
a cement circulated in the wellbore such that it surrounds the conduit and the reactive metal element; wherein the cement is set after surrounding the conduit; and wherein the reaction-inducing fluid contacts the reactive metal element and reacts with the reactive metal after the cement is set.
