Abstract
A system, method and apparatus for controlling a downhole operation is disclosed. A tool is operated to perform the downhole operation at a selected downhole location using a first value of an operation parameter of the tool. A magnetostrictive probe is used to determine a temperature profile along a section of a wellbore related to the operation being performed using the first value of the operation parameter. At least one temperature of the temperature profile is compared to a selected threshold. The operation parameter is altered to a second value based on the comparison of the temperature profile to the selected threshold.
