Multiscale matched-field processing for noise-source localization in exploration geophysics
In the study, we investigate the use of ambient-noise data to locate microseismic sources at
the exploration scale. We develop a multiscale matched-field processing (MFP) approach to …

Frequency-dependent attenuation as a potential indicator of oil saturation
B Quintal - Journal of Applied Geophysics, 2012 - Elsevier
At seismic frequencies, wave-induced fluid flow is a major cause of P-wave attenuation in
partially saturated porous rocks. Attenuation is of great importance for the oil industry in the …

Effective fluid bulk modulus in the partially saturated rock and the amplitude dispersion effects
AY Rozhko - Journal of Geophysical Research: Solid Earth, 2020 - Wiley Online Library
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 …
