Utah FORGE: Seismic DAS and Geophone Borehole Data Processing and 3D Imaging of Vp/Vs Ratio in the 2024 Stimulated Reservoir

Description

This dataset includes a final report and a 3D velocity model derived from seismic DAS and geophone borehole data collected during the April 2024 stimulation of the reservoir at Utah FORGE. The report details the processing of over 50,000 P- and S-wave travel times used in a tomographic inversion to estimate the Vp/Vs ratio, revealing anomalies adjacent to wells 16A and 16B that may be associated with injected fracturing fluids. Additionally, Wadati analysis of more than 27,000 pairs of differential P- and S-wave travel times supports this interpretation with a high Vp/Vs estimate of 1.86, averaged over the dimensions of the earthquake cluster. The accompanying data file provides a 3D model of P- and S-wave velocities and Vp/Vs ratios, structured with spatial coordinates and velocity values.

56 This ASCII file contains 3D P- and S-wave velocities and Vp/Vs ratio estimates obtained from seismic DAS and geophone borehole data recorded during the 2024 stimulated reservoir. The file contains six columns consisting of the distance and depth from the surface location of well 16A and Vp, Vs, and Vp/Vs: x [km], y [km], z [km], Vp [km/s], Vs [km/s] and Vp/Vs. https://gdr.openei.org/files/1723/3D_Vp_Vs_and_Vp-over-Vs_model_of_the_2024_stimulated_reservoir.xyz
