Detection of intersecting open fractures is an important task in many earth science domains.
To quantify the seismic responses in the fluid-saturated porous rock with intersecting open …

致密砂岩储层普遍具有孔隙度低, 微裂隙发育的特点, 岩石内部常含有强烈的结构非均质性.
致密砂岩发育的微裂隙使储层具有良好的连通性, 促成高饱和气的天然气成藏 …

Methane (CH 4) is a potent greenhouse gas that has a major impact on Earth's climate. CH 4
is accommodated in discrete bubbles in aquatic muds, whose sizes greatly exceed the pore …

Porosity, fluid type and rock texture significantly affect acoustic wave propagation, since
velocity dispersion and attenuation in fluid saturated rocks are mainly caused by wave …

Seismic anisotropy is an important attribute for fracture detection and characterization. If
fracture size is comparable to the wavelength or fluid diffusion length, the P wave anisotropy …

Understanding the stress-dependent elastic moduli of fractured rocks is essential for
monitoring geopressure and tectonic stress. The elastic nonlinearity with finite strains can be …

Tight-sandstone gas reservoirs have low porosity and contain developed microcracks, result
in the strong matrix heterogeneity. Due to the development of microcracks in tight sandstone …

Understanding the mechanisms of wave-induced fluid flow in the pore space combined with
attenuation and dispersion measurements may be used to estimate rock hydraulic …

We have performed ultrasonic measurements on tight siltstone samples to obtain the P wave
coda and intrinsic attenuations using a single isotropic scattering model and the spectral …

The radiated seismic energy is an important index for the intensity assessment of
microseismic (MS) events and the early warning of dynamic disasters. However, the energy …
