Horizontal-Component Prior-based Framework for Adaptive Shear-wave Leakage Suppression in OBC Data
Zheng Cong, Shiqi Dong, Xintong Dong +1
Shear-wave leakage in the vertical (Z) component of ocean-bottom cable (OBC) seismic data commonly results from the receiver tilt and poor seafloor coupling, introducing unwanted c…
PreAdaptFWI: Pretrained-Based Adaptive Residual Learning for Full-Waveform Inversion Without Dataset Dependency
Xintong Dong, Zhengyi Yuan, Jun Lin +3
Full-waveform inversion (FWI) is a method that utilizes seismic data to invert the physical parameters of subsurface media by minimizing the difference between simulated and observ…
Transformer for seismic image super-resolution
Shiqi Dong, Xintong Dong, Kaiyuan Zheng +3
Seismic images obtained by stacking or migration are usually characterized as low signal-to-noise ratio (SNR), low dominant frequency and sparse sampling both in depth (or time) an…
Self-Supervised Diffusion Model for 3-D Seismic Data Reconstruction
Xinyang Wang, Qianyu Ge, Xintong Dong +2
Seismic data reconstruction is an effective tool for compensating nonuniform and incomplete seismic geometry. Compared with methods for 2D seismic data, 3D reconstruction methods c…
MAE-GAN: A Novel Strategy for Simultaneous Super-resolution Reconstruction and Denoising of Post-stack Seismic Profile
Wenshuo Yu, Shiqi Dong, Shaoping Lu +1
Post-stack seismic profiles are images reflecting containing geological structures which provides a critical foundation for understanding the distribution of oil and gas resources.…
Transformer For Low-frequency Extrapolating of Seismic Data
Zheng Cong, Xintong Dong, Shaoping Lu +2
Full waveform inversion (FWI) is used to reconstruct the physical properties of subsurface media which plays an important role in seismic exploration. However, the precision of FWI…
