Modeling the effect of multiscale heterogeneities on wave attenuation and velocity dispersion

Y Wang, Z Zong, Q Sun - IEEE Transactions on Geoscience …, 2023 - ieeexplore.ieee.org
Wave attenuation and velocity dispersion are of great significance to fluid evaluation in fluid-
saturated rocks. Inspired by the double-porosity and cracked porous elastic wave theory, we …

Mass transfer between fluids as a mechanism for seismic wave attenuation: experimental evidence from water–CO2 saturated sandstones

S Chapman, JVM Borgomano, B Quintal… - Geophysical Journal …, 2022 - academic.oup.com
Seismic waves are typically assumed to propagate fast enough through a porous rock
saturated with multiple fluid phases such that the interaction between the fluids can be …
