Utah FORGE Project 3-2535: Compilation of Geodetic Data and Estimation of Associated Deformation

Description

Report on possible geodetic signature of the 3 stimulations in April 2022 as well as a comparison with existing InSAR data gathered over the site before, during, and after the stimulation. In geothermal production it is important to understand the existing stress field and the changes in the stress associated with field development. The stress field is a controlling factor in the development and properties of natural and stimulated fractures. Furthermore, changes in the stress field can lead to associated seismicity and the potential for felt earthquakes. It is difficult to estimate stresses directly and they are typically inferred from well tests and observed strain. In this task our goal is to incorporate observed strain data into the fully integrated models of the stimulations at the FORGE site. FORGE project 3-2535 is planning on using a casing source EM method for detecting and imaging a deep localized stimulated fracture zone at the Utah FORGE site. Details on other stages of the project are included in the linked GDR submissions below.

21 This short report details and tests the workflow that will be used to simulate steel well casings in deviated production/extraction boreholes at at the Utah FORGE site. Boreholes will be electrically energized and will serve as data sources for future proposed electromagnetic borehole surveys, which will be used to delineate/estimate the size and porosity of the main FORGE stimulated reservoir. https://gdr.openei.org/submissions/1433
