Utah FORGE: Phase-Picking Based Microseismic Event Catalog - April 2024 Stimulation
This catalog contains microseismic event locations recorded during the April 2024 stimulation at the Utah FORGE site. Events were detected and located using a phase-picking workflow that integrates downhole geophones (wells 56 and 78B) and downhole DAS (well 16B). P- and S-wave arrivals were automatically picked using PhaseNet. Phase association was performed using GaMMA, and event locations were computed using ADLoc with 200 bootstrap realizations (90% pick resampling per run). The highest-probability location was selected as the final event location, and spatial standard deviations were adopted as location uncertainties. Event magnitudes were estimated using a local magnitude formulation derived from GES (Geo Energy Suisse) catalog magnitudes and maximum DAS strain rate measurements. Both the microseismic event catalog and associated conference paper are provided here.
