| Abstract | This paper examines design issues and potential options for building logging tools for high entropy (>400°C) geothermal wells. At well temperatures greater than 400°C, today?s logging equipment cannot be used. These extreme temperatures create issues with the tool?s metal pressure housing, seals, thermal insulation, batteries, electronics and cables, both slick line and wireline. This paper discusses engineering tradeoffs between real time and memory tools. Potential solutions such as high-temperature electronics and active cooling are briefly discussed. |
