Utah FORGE: Seismic Activity from April, 2019

공공데이터포털

This dataset contains seismic event detections acquired using the 151 Nodal geophones deployed at the Utah FORGE site in April 2019. Details regarding the publishing are available in the paper linked below (Mesimeri, M. and K. L. Pankow et al. 2020). A frequency-domain-based algorithm for detecting induced seismicity using dense surface seismic arrays, Geophys. J. Int, submitted.

Utah FORGE: 2D and 3D Seismic Data

공공데이터포털

This set of data contains raw and Initially-processed 2D and 3D seismic data from the Utah FORGE study area near Roosevelt Hot Springs. Reprocessed versions of these data can be accessed at the linked submission in the Resources section titled "Reprocessed Seismic Reflection Data." The zipped archives numbered from 1-100 to 1001-1122 contain 3D seismic uncorrelated shot gatherers SEG-Y files. The zipped archives numbered from 1-100C to 1001-1122C contain 3D seismic correlated shot gatherers SEG-Y files. Other data have intuitive names.

Utah FORGE DAS Seismic Data 2022

공공데이터포털

This is a link to the website where DAS seismic data, collected from wells 78-32 and 78B-32 during the Utah FORGE 2022 stimulation, is now available for download. The data can be accessed at "Well 16A78-32 2022 Stimulation Seismicity Data" link in the submission under the Silixa heading. The page includes surface acquisition nodal datasets, downhole geophone data, and Silixa fiber data. Raw seismic stimulation data and the scripts to process this data is under the Silixa heading.

Utah FORGE: Induced Seismicity Mitigation Plan

공공데이터포털

This is the current induced seismicity mitigation plan (ISMP) for the Utah FORGE project. Information that was collected during Phases 1 and 2 of the Utah FORGE project has been incorporated, as have literature searches and risk assessments. The purpose of this report is to identify and mitigate induced seismicity for the Utah FORGE Project. Mitigation includes preliminary screening, outreach, criteria for ground vibration and noise, data collection practices, and natural seismic hazard analysis. From this, the overall risk from the project was determined. This report is subject to change as new information comes to light.

Utah FORGE: Source Imaging DAS-Based Seismic Event Catalog - April 2024 Stimulation

공공데이터포털

This catalog contains microseismic event locations recorded during the April 2024 stimulation at the Utah FORGE site. Events were detected and located using a DAS-specific source imaging workflow that avoids conventional phase picking. Instead, STA/LTA-transformed DAS and downhole geophone traces were back-propagated through a calibrated 1D velocity model to generate a coherency field across a 3D subsurface grid. Events were identified at locations where P- and S-wave back-projections constructively aligned, and associated uncertainties were estimated from the spatial coherency distribution.
