Full-waveform inversion (FWI) aims at estimating subsurface physical parameters by minimizing the misfit between simulated data and observations. FWI ......
P/S-wave separation is a key step for data processing in multicomponent seismic exploration. The conventional methods rely on either the prior informa......
Seismic facies classification aims to predict a facies model, or a set of facies models, from measured seismic data. We focus on stochastic classifica......

The free-surface boundary condition is a crucial aspect in the numerical modeling of (visco)elastic wave equations, especially when using a finite-dif......
The reservoir brittleness index can characterize the relative brittleness of shale oil and gas reservoirs, which provides guidance for hydraulic fract......
We describe a new method, full-waveform inversion by model extension (FWIME), that recovers accurate acoustic subsurface velocity models from seismic ......
We have evaluated the ensemble empirical mode decomposition (EEMD) and stacking model for borehole seismic-data denoising. The borehole records collec......
Time-lapse seismic difference refers to the comprehensive re-sponse of fluid saturation, pore pressure, and porosity. However, the contribution of dif......
The singular spectrum analysis (SSA) method can detect the low-rank structure of data and therefore has become a powerful tool in seismic data process......
Seismic denoising will inevitably cause signal leakage, which is seen as coherent signal energy in the removed noise profile. Most traditional methods......
