Anisotropy, focal mechanisms, and state of stress in an oilfield : passive seismic monitoring in Oman [PDF]
, 2005 Knowledge of the spatial characteristics of stress and fractures in reservoirs is important for optimising production and injection processes. Serni-permanent passive microseismic monitoring is being conducted in the Yibal field, Oman, to better ...

Characterization of a complex near-surface structure using well logging and passive seismic measurements [PDF]
Solid Earth, 2016 We combine geophysical well logging and passive seismic measurements to characterize the near-surface geology of an area located in Hontomin, Burgos (Spain). This area has some near-surface challenges for a geophysical study.

Geophysical Monograph Series, Page 117-131., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

4D Physics‐Based Pore Pressure Monitoring Using Passive Image Interferometry
Geophysical Research Letters, 2023 This study introduces a technique for four‐dimensional pore pressure monitoring using passive image interferometry. Surface‐wave velocity changes as a function of frequency are directly linked to depth variations of pore pressure changes through ...
