As the geothermal industry matures, there is a continuing need for innovative solutions to logging and instrumentation problems. The current state-of-the-art is dominated by conventional electronics in heat-shielded pressure barrels. But there are measurement tasks and instrumentation requirements that are not easily satisfied by the current style of tools, and long-term downhole exposure to geothermal temperatures is currently very limited. New high-temperature electronics may make long-term downhole tools more readily available and more reliable. Silicon-On-Insulator (SOI) electronic components and special battery concepts may lead to a new generation of Logging-While-Drilling (LWD) and Measurements-While-Drilling (MWD) tools, and for long-term, downhole monitoring requirements.
