Claim 0:
1. A method to monitor expansion of a metallic sealant, the method comprising:
deploying the metallic sealant along a section of a wellbore;
exposing the metallic sealant to a reacting fluid to initiate a first galvanic reaction, wherein the metallic sealant is configured to expand as a result of being exposed to the reacting fluid;
measuring, with a downhole temperature sensor deployed in the wellbore, a change in temperature due to heat released by the metallic sealant as a result of the first galvanic reaction;
determining an amount of expansion of the metallic sealant based on the change in the temperature and as a result of the first galvanic reaction;
applying pressure to the metallic sealant to expose a previously unexposed section of the metallic sealant;
exposing the previously unexposed section of the metallic sealant to the reacting fluid to initiate a second galvanic reaction;
measuring a change in temperature caused by the second galvanic reaction; and
determining an amount of a second expansion of the metallic sealant based on the change in the temperature caused by the second galvanic reaction.
