Passive seismic low-frequency (from approximately 1–6 Hz) data have been acquired at
several locations around the world. Spectra calculated from these data, acquired over fields …

Low frequency passive seismic spectral analysis has developed rapidly since the first
commercial pilot was described in First Break in 2005. David Walker1 of Spectraseis reviews …

Frequency dispersion is a well‐known effect in geophysics, which means that waves of
different wavelengths propagate at different velocities. Amplitude dispersion is a less‐known …

A 1-D model is presented that couples the microscale oscillations of non-wetting fluid blobs
in a partially saturated poroelastic medium with the macroscale wave propagation through …

Low‐frequency passive seismic experiments utilizing arrays of 3‐component broadband
seismometers were conducted over two sites in the emirate of Abu Dhabi in the United Arab …

Propagation of seismic waves in partially saturated porous media depends on various
material properties, including saturation, porosity, elastic properties of the skeleton, viscous …

Low-frequency shadows are frequently interpreted as attenuation phenomena due to partial
saturation with free gas. However, several researchers have argued that shadows are not …

A model is presented to describe how low-frequency vibrations can induce changes to
relative permeabilities in dual-porosity dual-permeability rocks. We show that a combination …

The purpose of this study is to investigate the seismic ambient noise spectral anomalies that
occur near gas reservoirs. These anomalies involve a significant spectral amplification of the …

ABSTRACT A low-frequency passive seismic experiment using an array of 49 3C
broadband seismometers was conducted over an onshore oil field in the emirate of Abu …
