Geophysical monitoring of landslides can provide insights into spatial and temporal
variations of subsurface properties associated with slope failure. Recent improvements in …

Source locations provide fundamental information on earthquakes and lay the foundation for
seismic monitoring at all scales. Seismic source location as a classical inverse problem has …

We compare the performance of a downhole distributed acoustic sensing (DAS) fiber‐optic
array with that of conventional geophones. The downhole collocated arrays are part of the …

Low-frequency (LF) signal content in seismic data as well as a realistic initial model are key
ingredients for robust and efficient full-waveform inversions (FWIs). However, acquiring LF …

Geological storage of CO2 that has been captured at large, point source emitters represents
a key potential method for reduction of anthropogenic greenhouse gas emissions. However …

This study presents the first demonstration of the transferability of a convolutional neural
network (CNN) trained to detect microseismic events in one fiber-optic distributed acoustic …

Earthquakes induced by subsurface fluid injection pose a significant issue across a range of
industries. Debate continues as to the most effective methods to mitigate the resulting …

We have developed a case study demonstrating the use of an “L”-shaped downhole fiber-
optic array to monitor microseismicity. We use a relatively simple method to detect events …

Distributed Acoustic Sensing (DAS) is gaining vast popularity in the industrial and academic
sectors for a variety of studies. Its spatial and temporal resolution is ever helpful, but one of …

Passive seismic monitoring of microseismic events induced in oil or gas reservoirs is known
as microseismic monitoring. Microseismic monitoring is used to understand the process of …
