Utah FORGE: Report and Associated Data from Measuring and Modeling Deformation 2018 through 2024

The report provided here describes research activities between August 16th, 2018 and July 30th, 2024. The goals of the research activities are to conduct an Interferometric Synthetic Aperture Radar (InSAR) analysis and Ground Surface Deformation Modeling at the Utah FORGE site. InSAR data have been obtained from two satellite missions and combined pair-wise into interferograms to assess ground deformation. These InSAR datasets are compiled below as links to their respective destinations in the GDR.

The project found that the InSAR data analyzed do not show any measurable deformation in the area immediately surrounding the FORGE wells and no vertical surface displacement that could be measurable by InSAR or GPS is expected from the stimulation experiments conducted at the site in 2023 or 2024. The report goes on to state the expected vertical displacement at the Earth's surface is less than 1 millimeter, based on modeling using an analytic solution. Hydromechanical modeling also predicts that the magnitude of the deformation produced by injection experiments is too small to be measured by InSAR or GPS.
