Major news outlets continue to cover Utah’s procurement of the final phase of the FORGE project. The U.S. Department of Energy will give the University of Utah up to $140 million to support a research laboratory studying geothermal energy.

June 14, 2018:

In release today, the U.S. Department of Energy (DOE) announced that the University of Utah will receive up to $140 million in continued funding over the next five years for cutting-edge geothermal research and development. After three years of planning, site characterization, and competition, the proposed site outside of Milford, Utah, has been selected as the location of the Frontier Observatory for Research in Geothermal Energy (FORGE) field laboratory. This new FORGE site is dedicated to research on enhanced geothermal systems (EGS), or manmade geothermal reservoirs. See this link.

Dec 13, 2017:

Last week the Utah FORGE project completed a two- and three-dimensional seismic surveys to further characterize the project area’s buried granite reservoir. Specifically, the survey may help to identify any buried faults that might be zones of fluid flow.
Seismic surveys create subsurface images by generating, recording, and analyzing sound waves that travel through the Earth (such waves are also called seismic waves). Density changes between rock or soil layers reflect the waves back to the surface, and how quickly and strongly the waves are reflected back indicates what lies below.
For the Utah FORGE survey, vehicle-mounted vibrator plates (called vibroseis trucks) generated the source waves and a grid of geophones recorded them. The survey included two 2D surveys that were 2.5 miles long and included approximately 160 source points and geophone receivers each, and a 3D survey that covered 7 square miles and included 1,100 source points and 1,700 geophone receivers. The data is now being processed to generate a three-dimensional map of the subsurface reservoir.

Stephen Potter presented a poster at the annual meeting of the Seismological Society of America in Denver on April 19. Stephen has been analyzing the historic seismicity around Milford the Roosevelt Hot Spring system, and the FORGE site. No seismicity has been detected at the FORGE site.


March 10, 2017:

In late March a drilling pad was prepared for an investigation well to be drilled this summer. This well will be drilled to 7000 feet, and will provide data on the thermal regime, rock type, permeability, and stress regime beneath the site.


January 27, 2017:

In mid-December 2016, a group of four graduate students deployed 96 three-component Nodal seismic instruments in two grid configurations centered on the proposed Utah FORGE site. It was cold and windy when the instruments were installed, but nothing like the weather they faced (snow and cold) in mid-January 2017 when they returned to retrieve the instruments. The data from these instruments will be used to look for extremely small (M 0 or less) earthquakes, and will be used to construct a subsurface image of the rocks beneath the proposed drill site.

Dr Robert Podgorney has joined the Utah FORGE team. Dr. Podgorney will be the Technical Expert on Reservoir Modeling activities. Dr. Robert Podgorney is a senior scientist and department manager at the Idaho National Laboratory and an affiliate faculty member with the Center for Advanced Energy Studies, a public–private research partnership between the INL and Idaho public research universities. He is currently developing a fully coupled hydro-thermal-mechanical simulator for modeling, with targeted applications for simulating enhanced geothermal systems and unconventional gas reservoirs. His research interests in general center on water and energy related issues, focusing on experimental, numerical, and analytical investigations of multiphase fluid flow in fractures and fracture networks and the development of massively parallel simulators for describing these systems. The International Partnership for Geothermal Technology has recently recognized his expertise in geothermal simulation, as he has been appointed to serve as the US Convener to the Reservoir Modeling Working Group for an indefinite term. His experiences ranges from field based well drilling and monitoring activities to regional scale groundwater management and modeling, for both environmental and energy applications.
