We have developed an optimal method to determine expan-sion parameters for flexible stencils in 2D scalar-wave finite-difference frequency-domain (FDF......
Wave-induced fluid flow (WIFF) between cracks and micro-pores is one of the major mechanisms causing attenuation and dispersion within seismic frequen......
Quantitative interpretation of waveform attenuation for determining petrophysical properties remains one of the most challenging problems associated w......
Reduced-rank filtering is a common method for attenuating noise in seismic data. Because conventional reduced-rank filtering distinguishes signals fro......
With geophysical surveys evolving from traditional 2D to 3D models, the large volume of data adds challenges to inversion, especially when aiming to r......
Seismic channel interpretation involves detecting channel structures, which often appear as meandering shapes in 3D seismic images. Many conventional ......
Ultradeep carbonate reservoirs have high temperatures and pressures, complex pressure/tectonic stress settings, and complex pore structures. These con......
Cavities under urban roads have increasingly become a great threat to traffic safety in many cities. As a quick, effective, and high-resolution geophy......
The physical basis, parameterization, and assumptions involved in root-mean-square (rms) velocity estimation have not significantly changed since they......
Seismic full-waveform inversion (FWI) estimates subsurface velocity structures by reducing data misfit between observed and modeled data. Simultaneous......
Lithology identification plays an essential role in geologic exploration and reservoir evaluation. In recent years, machine learning-based logging lit......
The removal of sinusoidal interference is an important step in seismic data processing, especially for data with low signal-to-noise ratios. The inter......
The time-space-domain finite-difference method (FDM) is widely used in forward modeling of wave equations. Conventional explicit FDMs (EFDMs) (with hi......
Wavefield decomposition can be used to extract effective information in reverse time migration and full-waveform in -version. The wavefield decomposit......
The electromagnetic radiation (EMR) method is a promising geophysical method used to monitor and provide early warnings of coal rock burst disasters. ......
