Lab Research on Microseismic Event Location Presented at AGU 2025
December 2025
We are pleased to share that Dr. Ariel Lellouch, head of the Photonic Seismology Lab, presented research at the AGU Fall Meeting in New Orleans. The poster presentation, titled "Picking-free microseismic event location with downhole DAS and geophones", showcased innovative methods for monitoring enhanced geothermal systems.
The work highlights the research of a Ph.D. student Eyal Shimony, and a MSc student Uri Wygodny, both from the Photonic Seismology Lab. They proposed a source-imaging approach that eliminates the need for traditional event picking, which often struggles with the high noise levels found in Distributed Acoustic Sensing (DAS) data. By applying this method to approximately 3,000 events from the 2024 FORGE stimulation, the team demonstrated how joint analysis of DAS and geophone data can overcome recording limitations to provide a clearer geomechanical interpretation of stimulation stages.
This collaborative effort featured a diverse team of experts, including co-authors Xiaoming Zhang and No'am Zach Dvory from the University of Utah, and underscores our lab's commitment to advancing fiber-optic seismology and developing robust tools for the next generation of geothermal energy monitoring.
