Claim 15:
16. A downhole metallic sealant measurement system, comprising:
a metallic sealant deployed along a section of a wellbore, wherein a first galvanic reaction is initiated when the metallic sealant is exposed to a reacting fluid, and wherein the first galvanic reaction causes an expansion of the metallic sealant to isolate a section of the wellbore, wherein the metallic sealant is configured to expand as a result of being exposed to the reacting fluid; wherein the metallic sealant is configured such that the application of pressure to the metallic sealant exposes a previously unexposed section of the metallic sealant; wherein the exposure of the previously unexposed section of the metallic sealant to the reacting fluid initiates a second galvanic reaction;
a temperature sensor positioned proximate to the metallic sealant and operable to determine a temperature change due to heat released as a result of the first galvanic reaction; wherein the temperature sensor is further operable to determine a temperature change due to heat released as a result of the second galvanic reaction; and
a logging tool configured to determine an amount of expansion of the metallic sealant based on the temperature change and as a result of the first galvanic reaction; wherein the logging tool is further operable to determine an amount of expansion of the metallic sealant based on the change in the temperature caused by the second galvanic reaction.
