DEEPEN Leapfrog Geodata Model Cleaned And Reformatted Exploration Datasets From Newberry Volcano

DEEPEN stands for DE-risking Exploration of geothermal Plays in magmatic ENvironments.

As part of the DEEPEN 3D play fairway analysis (PFA) conducted at Newberry Volcano for multiple play types (conventional hydrothermal, superhot EGS, and supercritical), existing geoscientific exploration datasets needed to be acquired, cleaned, reformatted, and assembled in Leapfrog Geothermal. This GDR submission includes all of the cleaned and reformatted (X (m), Y (m), elevation (m), processed data values) datasets used to build the Leapfrog Geodata model.

Existing datasets were acquired from the GDR, from AltaRock, and from other sources. This yielded the following datasets:

• Digital elevation model produced from LiDAR data by Ramsey and Bard, 2016
• MT surveys from 2006, 2011, 2014, and 2017 (including single inversions)
• Gravity surveys from 2006, 2007, and 2011 (including single)
• Earthquake catalogs from PNSN, LLNL, and the Newberry EGS Demonstration project
• Seismic velocity model from Templeton et al., 2014
• The Frone, 2015 temperature model and a new one produced through extrapolating downhole temperature measurements and the SMU temperature at depth maps. Two versions of the new model are provided: 250 m spacing and 500 m spacing
• EarthVision geologic model with alteration from Moser et al., 2016
• Well data from EGS well 55-29, deep geothermal wells, coreholes (GEO N-2 through 5) and several thermal gradient holes
• "Newberry Well Data:" Location, simple lithology, directional survey data, and temperature data for the 34 wells and coreholes used in the Newberry PFA

Although there are additional 2D datasets available in the area, such as aeromagnetic surveys, these were not included in the analysis. While it may be possible to project these datasets into three dimensions by assuming the surface measurements do not vary with depth, this method is associated with high uncertainty. Preexisting inversions of these data were unavailable, and inverting additional geophysical datasets is outside the scope of this project.
