Petroleum reservoir characterization using downhole microseismic monitoring
Imaging of microseismic data is the process by which we use information about the source locations, timing, and mechanisms of the induced seismic events to make inferences about the structure of a petroleum reservoir or the changes that accompany ...

Seismic Tremor as a Precursor to Hydrothermal Explosions Near Mutnovsky Volcano (Kamchatka)
Abstract Mutnovsky Volcano, ∼70 km SW of Petropavlovsk‐Kamchatsky, exhibits persistent degassing, hosts active hydrothermal springs and the Mutnovsky Geothermal Power Plant (MGPP) on its slopes. Using the network covariance matrix approach, we analyzed seismic data recorded in 2023–2024 by 15 seismic stations operating around Mutnovsky Volcano.

This study determines the impact critical stress early‐warning indicators for deep soft coal seams: 18 MPa (shallow holes), 20 MPa (deep holes), and 3 MPa/d daily stress change rate, via theoretical, experimental and simulation methods. ABSTRACT The accurate determination of early‐warning indicators for critical impact stress in deep soft coal seams is

Mining disturbance tends to trigger fault stick‐slip instability and induce disasters. This paper establishes a mechanical model to propose a critical criterion, which is verified to be reliable via FLAC3D, providing a theoretical basis for early warning of fault slip disasters.

Conditional Diffusion Model for Robust 3-D Microseismic Event Localization from Noisy Waveforms
Locating microseismic events is crucial to monitoring fracking activities, CO2 injection, and reservoirs in general. However, the process of locating such events is challenging, especially in low signal-to-noise scenarios.

This study investigates the effect of incorporating the Devil's Mountain Fault (DMF) and its interaction with the Leech River Valley Fault (LRVF) on the elastic surface deformation hazard in and near the city of Victoria, British Columbia, Canada. Previously, the surface deformation hazard of the region has been characterized by considering the LRVF ...

Adaptive microseismic noise estimation and denoising
Microseismic data recorded by surface arrays are often strongly contaminated by unwanted random noise. This background noise makes the detection of small magnitude events difficult.
