Utah FORGE 3-2535: Report on Geodetic Observations of Fracture Development During April 2024 Stimulations

Description

This report presents geodetic observations from the April 2024 stimulations at the Utah FORGE site, as part of LBNL FORGE Project 3-2535. It focuses on Distributed Strain Sensing (DSS) data from an optical fiber in well 16B, capturing localized strain linked to fracture propagation during several stimulation stages. DSS signals correlate well with injection timing and pressure, particularly during early stages like 3R. Microseismic data show spatial alignment with strain observations, supporting interpretations of fracture development. In contrast, InSAR analysis using Sentinel-1 data from 2019-2025 reveals no clear surface deformation.
