Conference Paper: Subsurface Electrical Measurements at Dixie Valley, Nevada, Using Single-Well and Surface-to-Well Induction Logging

Abstract
Extended logging and surface-to-borehole electromagnetic induction measurements were performed at the Dixie Valley Geothermal Field as part of an ongoing effort to employ electromagnetic induction logging to geothermal reservoir characterization. The principal goal of this effort is to discern subsurface features useful in geothermal production, such as larger scale mapping of geothermal reservoirs and smaller scale mapping of producing fractures in and around geothermal wells.The foremost goal of these measurements is to provide experience and insight that will be used toward the future development of geothermal,geophysical borehole technologies. Extended induction logging was performed during October 1998, using the MAIL (Multi Array Induction Logging) system. This system provides near well resistivity structure useful in explicating near well features. Surface-to-borehole induction logging was performed during December 1999, using the VEMP(Vertical Electro Magnetic Profiling) system. This system provides regional resistivity structure around the well useful in describing features distant from the well. Combined, these systems provide a comprehensive image of the resistivity structure surrounding the borehole.
