Title: East Mesa Geothermal Test Site

Abstract

The activities of the Bureau of Reclamation at East Mesa (California) Test Site and the results of its geothermal desalting program are described. Data on location, geothermal characteristics, and results of the chemical analysis of East Mesa geothermal wells are presented. Investigations including direct contact heat exchanger experiments, and energy conversion systems are mentioned, as are the well interference tests using highly sensitive electronic pressure gauges (over 0.01 psi). Injection operations are discussed, and it is found that wellhead silica concentrations appear to be related to flow rate. A seismic monitoring system, and a subsidence monitoring system, are outlined. The Multistage Flash (MSF), Vertical Tube Evaporator (VTE), and High Temperature Electrodialysis (HTED) desalting systems are discussed in detail. It is concluded that the systems have shown the capability to desalt geothermal fluid, and problems associated with each have been identified together with probable solutions.
