Snake River Plain FORGE Site Characterization Data

The site characterization data used to develop the conceptual geologic model for the Snake River Plain site in Idaho, as part of phase 1 of the Frontier Observatory for Research in Geothermal Energy (FORGE) initiative. This collection includes data on seismic events, groundwater, geomechanical models, gravity surveys, magnetics, resistivity, magnetotellurics (MT), rock physics, stress, the geologic setting, and supporting documentation, including several papers. Also included are 3D models (Petrel and Jewelsuite) of the proposed site.

Data for wells INEL-1, WO-2, and USGS-142 have been included as links to separate data collections.

These data have been assembled by the Snake River Geothermal Consortium (SRGC), a team of collaborators that includes members from national laboratories, universities, industry, and federal agencies, lead by the Idaho National Laboratory (INL). Other contributors include the National Renewable Energy Laboratory (NREL), Lawrence Livermore National Laboratory (LLNL), the Center for Advanced Energy Studies (CEAS), the University of Idaho, Idaho State University, Boise State University, University of Wyoming, University of Oklahoma, Energy and Geoscience Institute-University of Utah, US Geothermal, Baker Hughes

Campbell Scientific Inc., Chena Power, US Geological Survey (USGS), Idaho Department of Water Resources, Idaho Geological Survey, and Mink GeoHydro. 3D model of the INL site. Model 2 shows the same system of calderas shifted to the south, beyond the boundaries of the GRRA. Here we assume that the boundary between volcanics and Paleozoic rocks is defined by a flexural surface that was formed in response to the emplacement of a dense mid-crustal sill beneath the ESRP. This model is supported by the attitudes of ancient fold hinges within the mountains north of the plain. Fold hinges near the boundary of the plain plunge towards the plain at around 30 degrees. North of the plain, the plunge angles decrease in a more or less uniform manner. Thus, in this model, the base of the volcanic system is defined by a planar feature dipping 30 degrees to the south.
