Pressure prediction has long been one of subject of research focuses in petroleum geology
and exploration, but is traditionally limited to moderately overpressured formations due to …

Rock-physics templates establish a link between seismic properties (eg, velocity, density,
impedance, and attenuation) and reservoir properties such as porosity, fluid saturation …

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 …

Ultrasonic P-wave attenuation was measured in tight oil siltstones, carbonates and a tight
sandstone with two independent estimation methods. The dependence on saturation in gas …

We estimate the seismic attenuation and velocity dispersion induced by fluid pressure
diffusion in a saturated porous medium containing a sparse distribution of aligned slit …

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 …

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 …

Seismic attenuation measurements, especially those obtained from coda decay analysis,
are becoming a key data source for the characterization of the heterogeneous Earth due to …

Fractures control fluid flow in geological formations because their presence can greatly
affect effective permeability. Existence of cracks in a porous rock can induce seismic …

Ultrasonic receiving wave can reflect physical properties and damage degree of coal
samples. Therefore, it is of great significance to deeply study the parameters of ultrasonic. In …
