Project Title High-Temperature Circuit Boards for use in Geothermal Well Monitoring Applications
Project Type / Topic 1 Recovery Act: Enhanced Geothermal Systems Component Research and Development/Analysis
Project Type / Topic 2 High-Temperature Downhole Tools

Project Description Geothermal energy offers an abundant, renewable source of power that could be used to ensure the long-term energy independence of our nation. Currently, geothermal power in the United States is produced from relatively shallow wells that also contain naturally occurring water sources. These current geothermal power plants with near-ideal conditions for geothermal power production exist primarily in the western U.S. In order to expand the use of geothermal energy, new technologies are needed that will enable the utilization of the hot, dry rock located at depths up to 10 km. The introduction of water into these deep wells to create geothermal reservoirs is referred to as Enhanced Geothermal System (EGS).

An important near-term need for the EGS community is data-logging tools that can withstand the very high temperatures (on the order of 350°C) in these wells. These tools are used to explore and map the underground structures and thereby identify regions capable of supporting the production of energy by EGS processes. Because these logging tools are required to operate at extreme depths it is desirable to perform the sensor signal processing near the logging tool and then transmit the information to the surface. The temperatures at these depths presents a challenge for geothermal data logging because the electronic packages, and most notably the multilayer circuit boards onto which the electronic modules are built, were not specifically designed for use under these conditions.

Key elements of the work plan include evaluating various organic and inorganic polymers for use in this application, validating the electromechanical performance of these materials at EGS-relevant conditions, and fabricating and testing functional electronic packages to validate the technology.

Objectives An important near-term need for the EGS community is data-logging tools that can withstand the very high temperatures (on the order of 350°C) in EGS wells. Therefore, Composite Technology Development, Calumet, A-Power, and Sandia National Laboratory are proposing to develop and demonstrate a new class of high-temperature multilayer circuit boards that can operate reliably in EGS wells.
