PDF Version Also Available for Download.

Description

As part of the Geothermal Logging Instrumentation Development Program being conducted by Sandia Laboratories for the Department of Energy's Division of Geothermal Energy, high resolution, quartz crystal based, downhole pressure instruments are being developed. Under a joint no-cost contract, Sandia and Paroscientific, Inc., of Redmond, Washington, are working to upgrade a Paroscientific transducer for operation at 275/sup 0/C. In addition, Sandia Laboratories has been investigating various design configurations and fabrication techniques for high temperature quartz resonators and their associated electronic circuits. The goal of these efforts is to achieve a resolution of 0.01 psi in a 0 to 7000 psi ... continued below

The goal of these efforts is to achieve a resolution of 0.01 psi in a 0 to 7000 psi range and in temperatures up to 275/sup 0/C. The progress and plans for this project will be reviewed and hardware samples will be displayed.
