AbstractConventional water wells use well logging cameras to inspect the well. Today, geothermal wells must be cooled before video inspection. Cooling the well by pumping cold water into the well is expensive and damaging to the well. The well casing undergoes extreme changes in stress when the well is temperature cycled; lose your casing lose your well. As such, the benefits of visually inspecting the inside a geothermal well is almost never performed. Perma Works is a leader in high-temperature electronics. Perma Works is building a high-temperature well logging camera based on the electronics designed for high-temperature aircraft control systems, primarily the ARM7 microprocessor from RelChip. This microprocessor can operate & gt;250C (485F) indefinitely. The actual camera chip is very small and will be actively cooled inside the tool by a novel cooling process. Perma Works goal is not only to develop a high-temperature well inspection camera but for the camera to run on conventional geothermal logging equipment. As such, the cost and effort to run our camera inside a geothermal well is no more difficult than any other geothermal logging tool.
