We derive a time-domain differential equation for modelling seismic wave propagation in
constant-Q viscoelastic media based on fractional spatial derivatives, specifically Laplacian …

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

The quality factor Q is a dimensionless measure of the energy loss per cycle of a wave field,
and a proper understanding of this factor is important in a variety of fields, from seismology …

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 quality factor (Q) from seismic reflections by using a tomographic inversion
algorithm based on the frequency‐shift method. The algorithm is verified with a synthetic …

We develop a petro‐elastical numerical methodology to compute realistic synthetic
seismograms and analyze the sensitivity of the seismic response when injecting carbon …

作为一种非常规油气资源, 页岩油储量丰富, 分布范围广, 具有巨大的勘探开发潜力,
是近年来油气产业关注的重点与热点. 然而, 页岩油储层具有岩石矿物组分多样, 低孔低渗 …

P-wave attenuation by slow-wave diffusion is a significant loss mechanism at seismic
frequencies. This effect is known as mesoscopic loss, because it is a consequence of fluid …

In the Lorraine area of eastern France, decades of iron-ore mining from 1850 to 1997 have
left vast underground cavities beneath or in the vicinity of urban areas. Several major …

Geological storage is one of the solutions to avoid the emission of carbon dioxide to the
atmosphere. This process requires a careful monitoring of the CO 2 bubble, which can be …
