Abstract

Summary

Real-time microseismic monitoring is crucial for managing risks associated with geo-resource exploitation. SeisComP, developed by the GFZ and gempa GmbH, is a widely used tool enabling automated seismic data acquisition and processing. This study presents an optimized SeisComP workflow for monitoring an Underground Gas Storage field in Northern Italy using two years of seismic data from a 15-station network, including surface and borehole sensors. To improve earthquake location accuracy, a Joint Hypocenter and Velocity technique was applied to develop a new 1D P and S velocity model for the study area. Subsequently, a 3D P-wave velocity model was derived using migration data from a 3D seismic reflection survey, and a 3D S-wave model was estimated using an average Vp/Vs ratio based on the 1D model and well-log data. Comparing velocity models revealed significant improvements in earthquake location accuracy, particularly within the reservoir area when using the 3D model. Events outside this zone also are enhanced using the optimized 1D model. This approach, fully integrating a 3D velocity model into real-time monitoring, aligns with Italian guidelines and represents a pioneering application in enhancing microseismic monitoring precision for industrial activities.
