在讨论地震波传播理论时, 大部分情况下是把地震波看作弹性波. 事实上, 地下介质是非完全弹性
介质, 这使得传统的均匀, 完全弹性介质理论受到了严重挑战. 地震波在裂隙岩石中传播受裂隙 …

Fluid identification using seismic data is critical for the characterization of hydrocarbon
reservoirs. Poroelastic behaviors associated with wave-induced fluid flow allow for …

In VTI media, the conventional inversion methods based on the existing approximation
formulas are difficult to accurately estimate the anisotropic parameters of reservoirs, even …

Predicting gas saturation is critical for identifying gas zones in tight sandstones, but
poroelastic behaviours of tight sandstones with low porosity and permeability lead to …

ABSTRACT P-and S-wave inverse quality factors quantify seismic wave attenuation, which
is related to several key reservoir parameters (porosity, saturation, and viscosity). Estimating …

Recently, the great potential of seismic dispersion attributes in oil and gas exploration has
attracted extensive attention. The frequency-dependent amplitude versus offset (FAVO) …

The seismic properties of rocks are known to be sensitive to partial liquid or gas saturation,
and to aligned fractures. P-wave anisotropy is widely used for fracture characterization and …

Simulation of wave propagation in a constant-Q viscoacoustic medium is an important
problem, for instance, within Q-compensated reverse time migration (RTM). Processes of …

ABSTRACT P‐wave‐to‐S‐wave ratios are important seismic characterization attributes.
Velocity ratios are sensitive to the petrophysical properties of rocks and to the presence of …

This paper describes a workflow that combines machine learning and frequency-related
multi-attribute analyses to predict the occurrence of water, oil, and high or low gas …
