Jim Faulds at Fly Ranch Geyser
Jim Faulds, geologist and research professor at the University of Nevada, Reno's Bureau of Mines and Geology, lectures his geothermal exploration class in April at the Fly Ranch Geyser north of Gerlach, Nevada
Jim Faulds, principal investigator for the project, geologist and research professor at the University of Nevada, Reno, has a team of six researchers and several graduate students working with him on various aspects of the project.
"Of the 463 geothermal sites to study, we've studied and characterized more than 250 in the past year, either using existing records or on-site analyses," Faulds
"We'll continue to study more of the sites so we can develop better methods and tools for geothermal exploration.
Most, about two-thirds, of the geothermal resources in the Great Basin are blind - that is, there are no surface expressions, such as hot springs, to indicate what's perhaps 1,500 feet below the surface."
Better characterization of known geothermal systems is critical for new discoveries, targeting drilling sites and development, Faulds
The success of modeling sites for exploration is limited without basic knowledge of which fault and fracture patterns, stress conditions, and stratigraphic intervals are most conducive to hosting geothermal reservoirs.
"The geothermal industry doesn't have the same depth of knowledge for geothermal exploration as the mineral and oil industries," he
"Mineral and oil companies conducted extensive research years ago that helps them to characterize favorable settings and determine where to drill.
With geothermal, it's studies like this that will enhance understanding of what controls hot fluids in the earth's crust and thus provide an exploration basis for industry to use in discovering and developing resources."
team have defined a spectrum of favorable structural settings for geothermal systems in the Great Basin and completed a preliminary catalogue that interprets the structural setting of most its geothermal systems.
"This is the first attempt to broadly characterize and catalogue Great Basin geothermal systems in this way," he
In addition, Faulds has developed and taught a geothermal exploration class, published many papers on his work and presented his work at many conferences, including the World Geothermal Congress in Bali, Indonesia and the GEONZ2010 Geoscience-Geothermal Conference in Auckland, New Zealand.
"We want to help the industry achieve acceptable levels of site-selection risk ahead of expensive drilling," he
