Abstract The distribution of hydraulic‐fracturing‐related seismicity is largely controlled by subsurface structures, yet the physical process that governs redistribution injected fluids and stress heterogeneity remains underexplored due to a lack observational constraints. In this study, we monitored an active hydraulic fracturing (HF) well for two months with surface nodal array 60 three‐component stations. We built high‐resolution catalog comprised 1369 events (; Mc = −0.2). Their...
Abstract Dense arrays deployed near the hydraulic fracturing (HF) wells greatly enhance understanding of injection‐induced seismicity. In this study, we revisit continuous recordings that are acquired by 69 three‐component nodes at an HF site in Alberta, Canada, taking advantage a machine learning‐based seismic detection and location workflow. The obtained new earthquake catalog contains 21,619 events with relative errors <1 m, which exceeds ∼20% number earthquakes (18,040) reported...
The spatial distribution of hydraulic fracturing-induced seismicity is controlled by regional tectonics and local geological structures. In this study, we integrated a high-resolution shear velocity model from ambient noise imaging with 3D seismic reflection data to investigate structural influences on induced near an active fracturing (HF) platform in the Sichuan Basin, China. We conducted continuous monitoring throughout period located over 1,000 earthquakes within 7 weeks stimulation....
A thorough understanding of geological and hydraulic fracturing aspects can offer significant insights into the physical mechanisms governing earthquakes. In this study, we conducted seismic monitoring near a well-pad in southern Sichuan Basin. The adopts dense array that consists 60 three-component stations, last for duration 53 days. Accordingly, resolved located over 1,000 events (-1.43<M<2, Mc=-0.72). Most (~ 70%) distributed southwest direction injection wells, delineating series...
