Exposure Testing and Temperature Sensors for Down-Hole Geothermal Reservoir Monitoring.

This project reviews the limitations in current down-hole monitoring technologies for geothermal energy systems and introduces microelectromechanical systems (MEMS) sensors as a means of optimizing well performance. The use of continuous, real-time, down-hole monitoring can improve geothermal well efficiencies and increase well life. A variety of materials used in the fabrication of MEMS sensors have been tested in an experimental geothermal environment and exposed for up to 100 hours. Passive, capacitive temperature sensors have been designed to monitor the down-hole environment. These sensors can be coupled to an LCR tank circuit for wireless transmission.
