“…In addition to Biot's papers, several excellent detailed discussions are available (Stoll, 1989;Neuzil, 2003;Silin et al, 2004;Pride, 2005, Lo et al, 2008. Biot's theory predicts three body waves: two P waves and one S wave.…”

“…For the slow wave, the relative fluid-solid displacement is much larger than the displacement of the solid grains and is exactly out of phase with the solid displacement. The high attenuation of pressure diffusion waves is a consequence of energy losses in the fluid flow in the pores (Silin et al, 2004). In the seismic band of frequencies (< 10 kHz), the slow wave is a pure pore-fluidpressure diffusion.…”

“…Deformation of the rock matrix and the pore space is then just caused by rearrangements of the grains. In this case, Silin et al (2004), Pride (2005), and others have shown that Biot's wave equations for the low-frequency domain (below the critical Biot frequency and within the entire frequency band of interest in exploration seismology) can be approximated to yield the transient diffusion equation commonly used by groundwater hydrologists and the starting point for equation (1):…”

Most natural crustal earthquakes fall into one of two categories:(1) those associated with the dynamics of plate tectonics, or (2) those associated with the elements of the hydrologic cycle. This paper presents a comprehensive listing of published examples of hydroseismicity, a hypothesis that attributes most intraplate and near-intraplate earthquakes to the dynamics of the hydrologic cycle, which includes hurricanes and typhoons. Results from 30 worldwide studies of earthquake-rainfall correlations published during the past 22 years are referenced. These investigations were conducted in both intraplate and plate marginal environments on five continents. Collectively, they provide strong support for the hydroseismicity hypothesis as a viable explanation via pore-fluid-pressure diffusion for the occurrence of many earthquakes, regardless of the host tectonic regime. Signatures of pore-fluid-pressure diffusion in the Earth's crust are ubiquitous. Slow earthquakes result from crack development driven by pore-fluid-pressure diffusion. These earthquakes, also called silent earthquakes, take days, weeks, or even months to release energy instead of seconds or minutes as in normal earthquakes. Typhoons can trigger slow earthquakes in some areas. Hurricanes are believed to have triggered earthquakes in the eastern United States. Their explanation is provided for the most part by Biot's theory for wave propagation and pore-fluid-pressure diffusion in poroelastic media.

The amplitude spectrum gradient of seismic data is the rate of seismic reflection amplitude versus frequency within the effective bandwidth, which highlights the variation of seismic amplitude with different frequencies. Integrated within the seismic responses of porous media and fluids properties, this paper presents the concept of amplitude spectrum gradient, analyzes its geological significance, and illustrates the relationship of this attribute to the ratio of sand to shale. The application of thin bed reservoir identification demonstrates that the amplitude spectrum gradient is a powerful method in the identification of thin bed reservoirs that are about 3-5 m in study area. The success in identification thin bed distribution has been verified by wells drilled, which shows that the technique is useful in thin bed reservoir characterization based on seismic data.

Furthermore, Silin and Goloshubin () extended the work to build an asymptotic model of seismic reflection from a permeable layer, and through the analysis of wave field characteristics of the fast and slow waves in low‐frequency domain, they found an asymptotic solution with a slightly different choice of the small parametre and abandoned the assumption of grain stiffness.…”

This paper presents a new methodology for estimating reservoir fluid mobility using synchrosqueezed wavelet transforms. Synchrosqueezed wavelet transforms, which adopts a reassignment method, can improve the temporal and spatial resolutions of conventional time‐frequency transforms. The synchrosqueezed wavelet transforms‐based fluid mobility estimation requires the favourable selection of sensitive low‐frequency segment and more accurate estimation of the change rate of the low frequency segment in the spectrum. The least‐squares fitting method is employed in the synchrosqueezed wavelet transforms‐based fluid mobility estimation for improving the precision of the estimation of change rate of the low‐frequency segment in the spectrum. We validate our approach with a model test. Two field examples are used to illustrate that the fluid mobility estimation using the synchrosqueezed wavelet transforms‐based method gives a better reflection of fluid storage space and monitors hydrocarbon‐saturated reservoirs well.
