Low-Cost, High-Temperature Logging Tool for Geothermal Wells

61085 Current geothermal logging tools for temperature, pressure, and total dissolved solids measurement are expensive and require a heat shield. They can only survive a limited number of hours in high temperature environments. This project will design and fabricate a high temperature logging tool for measurement of temperature, pressure and total dissolved solids for geothermal and other energy industries. By eliminating the thermal flask, the tool will permit direct wireline data logging and permanent installations. In Phase I, current downhole steam injection loggings tools were modified to incorporate high temperature components. Onboard electronics were designed, along with supporting software, and the mechanics of assembling the unflasked logging tool for geothermal wells was determined. Phase II will develop and commercialize a high temperature logging tool for the measurement of temperature, pressure, and total dissolved solids for geothermal and other energy industries. Commercial Applications And Other Benefits as described by the awardee: The high temperature logging tool for simultaneous measurements of temperature, pressure, and total dissolved solids would produce more efficient and accurate geothermal well exploration and products, and related products would be competitive for use in other energy industries
