Topic: Steamboat Complex Geothermal System, Reno, Nevada: History, Geology, and Reservoir Characteristics, by Patrick Walsh, Greg Rhodes, Lara Owens, Paul Spielman, John Akerley

Abstract: The Steamboat Geothermal System in Reno, NV has a long history of geothermal utilization for spas dating back to the 1800s and electricity generation since 1986. Ormat Nevada Inc. has operated the entire Steamboat Field since 2004. Currently, geothermal wells at Steamboat Hills Geothermal System in Nevada produce 78 MW from 7 power plants and 2 connected reservoirs. Upper Steamboat produces ~380-400 °F from fractured metasediments at 2500-3000 ft depth and Lower Steamboat produces ~300 °F from fractured and altered granodiorite at 500-1000’ depth. The deeper wells target orthogonal high angle fractures striking NE-SW and WNW-ESE and dipping between 55 and 85 degrees. The shallower wells in Lower Steamboat produce from lower angle fractures that may have been caused by unloading associated with erosion prior to deposition of Tertiary and Quaternary volcanic rocks and sinter deposits. Recent drilling and reservoir modeling have provided data needed to optimize field operations, maximizing production and minimizing resource cooling.
