Abstract
A system for extending the life span of electronic components in a high temperature well. A thermal electric cooler is located in a position thermally communicating with the electronic component in the well. The thermal electric cooler lowers the temperature of the electronic component to a temperature that retards the deterioration of the electronic component, and is particularly useful in well completion tools requiring an extended life. One or more thermal electric coolers or other electrical equipment may be connected to a common electric wire, and a surface controller may selectively adjust the power supplied to each thermal electric cooler to prevent the electric wire from being overloaded. The power to each component can be controlled to produce the lowest attainable temperature for each thermal electric cooler, which reduces the deterioration of electronic components to the greatest extent possible.
