This is the Utah FORGE annual report for Phase 3A year 1, which was completed on December 28th, 2020. This report includes site infrastructure, site operations, seismic monitoring, a conceptual geological model, outreach, and communications for the Utah FORGE project during Phase 3A in 2020. Utah FORGE projects showcase the role of geothermal energy and Enhanced Geothermal Systems (EGS) as a renewable source of power for the United States. The geoscientific investigations done in the Utah FORGE projects demonstrate the surrounding region holds significant potential for future EGS development.

This is the annual report for Utah FORGE Phase 3A, year two, which was published on July 28th, 2022. The report includes site infrastructure, site operations, seismic monitoring reports, FORGE modeling reports, and external research and design. The ultimate objective of Utah FORGE is to demonstrate the viability of Enhanced Geothermal System (EGS) energy development. This report presents an overview of Phase 3A Year 2 activities. Year 1 activities transitioned the Utah FORGE project from site characterization and baseline monitoring to infrastructure development required for full deployment of the Utah FORGE laboratory.

This dataset consists of a comprehensive report documenting the stimulation program conducted in May 2024 on Utah FORGE wells 16A(78)-32 and 16B(78)-32. It includes detailed accounts of operational and scientific objectives, stimulation methodologies, and testing outcomes. The report describes the hydraulic fracturing activities, equipment setups, proppant and fluid usage, and the execution of a nine-hour circulation test. It also includes observations from seismic and fiber optic monitoring systems, providing data on microseismic activity and fracture propagation. Detailed parameters for each stimulation stage are provided, alongside operational challenges and solutions. The dataset includes analyses of injection and production rates, well temperatures, and pressure data, supported by graphical illustrations and logs.

The zip file below contains daily reports produced during the spring 2024 stimulation of wells 16A/16B(78)-32 at Utah FORGE . These reports cover a period from March 29th to April 28th, 2024. They discuss the activity on the rig each day, with each report containing information on general operations, management, safety, and weather.

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.

This drilling data for Utah FORGE well 16B(78)-32 include a well survey, core summary, mud and mud temperature logs, daily reports of the drilling process, and additional data from the Pason oil and gas company. Well 16B(78)-32 serves as the production well for reservoir creation, fluid circulation, and demonstration of heat extraction for the FORGE project. It has been drilled as a doublet approximately 300 feet parallel to and above the injection well 16A(78)-32. The proposed total depth was 10,658 feet, which was exceeded. Spudding began on April 26th, 2023. As of June 20th, 2023, the total depth measured 10,947 feet and the vertical depth measured 8,357 feet. Drilling included the trial use of insulated drill pipe (IDP) from Eavor Technologies, which was considered a success. IDP restricts counter-current heat transfer between drilling fluid inside the drill string and hotter returning fluid in the annulus, thereby ensuring the bottomhole assembly (BHA) remains submerged in cool fluid. Eavor rented 350 joints of IDP to FORGE which were run in two consecutive BHAs at the well. The results of this trial are included here.
