Abstract

New high-quality tensor MT data at 122 sites, including the vertical magnetic field and utilizing ultra-remote referencing, have been acquired over the Utah FORGE project area. The results will be used to delineate the densities of faults and fractures in crystalline basement rocks, to define the heat sources, and to derive baseline 3D resistivity structure for later MT monitoring of temporal changes in resistivity structure following well stimulation in the EGS reservoir. There are three files here related to Utah FORGE magnetotelluric (MT) data acquisition and processing. The FORGE MT EDIs zip file contains the observed MT responses in industry-standard EDI format. For each site, there is an EDI response file that utilized a local independent reference for noise cancellation, and a file that utilized a distant reference cancelling noise associated with the DC transmission line of the Delta IPP passing down the west side of Milford Valley. These two site files could be merged as appropriate. The FORGE Model Cell Center file contains the model volume of the 3D Forge MT inversion for characterizing the resistivity structure in the project area. It was derived using finite element inversion methodology described in Wannamaker et al, in the attached FORGE Phase3more »« less

SubTER Final Magnetotelluric (MT) Data: Mineral Mountains, Utah

Dataset Wannamaker, Phil

Subsurface Science, Technology and Engineering Research, and Development (SubTER) Crosscut is a collaboration across the Department of Energy offices involved in research activities in energy production/extraction, subsurface storage, and environmental remediation. This submission contains the edi-format responses of 80 tensor MT soundings taken over the Mineral Mountains of SW Utah by contractor Quantec Geoscience Inc. as part of the SubTER project. It includes contractor png images of the soundings plus the responses computed with two different remote references. There is also a readme text file that contains more information about the dataset.
Utah FORGE: MT Stations and Raw Data

Dataset Moore, Joe

There are two zipped folders in this submission. One contains a shapefile with the position of MT stations around the Milford FORGE Site, while the other has the raw MT data.
Utah FORGE: Phase 3 Ground Water Level Monitoring Data

Dataset Kirby, Stefan

Groundwater data around the Utah FORGE site has been collected to determine the piezometric levels and compositional variability. Field measurements in 2020 are designed to obtain and survey new groundwater wells that have been drilled on the distal periphery of the Utah FORGE project area. The spreadsheet included in this submission contains ground water level data from the Utah FORGE site as monitored from wells WOW-2 and WOW-3. The well locations are also provided as UTM, Zone 12, NAD83 coordinates.
Utah FORGE: Phase 3 Microgravity Data

Dataset Hardwick, Christian

A 4D microgravity survey began in early 2019 in order to benchmark surface and subsurface elevations prior to Phase 3 drilling and stimulation campaigns. Microgravity stations are collocated with GPS deformation benchmarks and use the same location survey data. Surveys are undertaken on a quarterly basis. The focus of current activities is comparative analysis of GPS survey results and InSAR analysis (see GDR Submission 1251) to check seasonal variance and to evaluate possible changes in the groundwater elevation. The attached zip file contains a text file and an Excel spreadsheet containing Utah FORGE Phase 3 processed "final" microgravity data throughmore »« less
