Local Seismic Monitoring of a Stimulation at the Utah Frontier Observatory for Research in Geothermal Energy Site
The Utah Frontier Observatory for Research in Geothermal Energy (FORGE) site is a Department of Energy funded research facility whose mission is to promote the development of technologies needed for enhanced geothermal energy production. Research topics are related to drilling, reservoir development, fluid exchange and methodologies to mitigate induced seismicity. At the Utah FORGE site, seismic monitoring consists of two phases: (1) monitoring reservoir development (presented in the companion abstract, by Dyer et. al) and (2) local monitoring of induced seismicity. In February 2021, the first horizontal well was completed and the plan is for this well to be stimulated in mid-March 2022. The local 14 station seismic network includes a combination of shallow borehole broadband and strong-motion stations, surface broadband stations and strong-motion stations near structures. The seismic data from this network are integrated into the regional monitoring at the University of Utah Seismograph Stations. Automatic alarms are configured to alert based on a Traffic Light System developed for Utah FORGE. We present details on the local seismic network, background seismicity, the Traffic Light System and preliminary results from the March well stimulation, including any alerts.
