In April 2024, the stimulation of the production and injection wells created the fracture network that forms the reservoir. It was followed by a successful commercial scale circulation test.

Map view and the location of the Utah FORGE project
Recently published in Geothermics, this paper by Peter Niemz et al. of University of Utah Seismograph Stations (UUSS) describes seismic observations from the circulation tests at Utah FORGE in July 2023 using only the regional (near-)surface network of the UUSS. The analysis provides a detailed picture of deep subsurface process. Observations indicate fracture growth and a complex interplay of seismic and aseismic responses in closely located volumes of the geothermal reservoir. Additionally, this work points out some remaining challenges regarding creating fluid pathways between injection and production wells in basement rock, that will be addressed in the upcoming phase of the Utah FORGE project.
