Institutional Standardization of Geothermal Fluid Characterization Techniques

Abstract

The characterization of geothermal fluid has been performed over the years using a wide variety of techniques. Some of these have led to very inaccurate results with subsequent uncertainty as to the true nature of the resource. In the also years several organization have worked to correct the situation and arrive at standard methods. The program at Battelle to achieve these ends is described. The formation of the ASTM Geothermal Resources Committee and Environmental Protection Agency efforts are related to the program. The participation of industry is described, and additional participation is solicited for this current and final phase. The complimenting parts of the Battelle Geothermal Program are described: the development of high pressure, temperature instruments and the monitoring of the performance of operating plants (Magma's binary cycle facility).
