Journal Article

A high-resolution method of spectral fitting with horizon constraints and its application

Deng, Haibo; Cheng, Xiaoyan; Zeng, Yongjian; Tianwei, Du

2023 Journal of Geophysics and Engineering

doi:10.1093/jge/gxad042

When seismic waves propagate underground, subsurface media can absorb high-frequency components of the seismic waves, resulting in attenuation of the high-frequency portion of the seismic data. Therefore, the seismic resolution is low and it is difficult to provide the information needed for thin...

Improved adaptive thin-layer inversion for semi-airborne transient electromagnetic method

Xian, Yougong; Lan, Riyan; Liu, Yuchao; Li, Dunren; Yang, Jing; Sun, Huaifeng

2023 Journal of Geophysics and Engineering

doi:10.1093/jge/gxad045

ABSTRACTTo improve the resolution of electromagnetic inversion for thin layers, electromagnetic one-dimensional inversion was studied. The smooth conductivity model produced by Occam's inversion cannot accurately represent the information of the subterranean thin resistive layers, leading to...

Parameter interpretations of wave dispersion and attenuation in rock physics based on deep neural network

Wang, Bochen; Liu, Jiawei; Guo, Zhenwei

2023 Journal of Geophysics and Engineering

doi:10.1093/jge/gxad058

Acoustic wave features, including velocity dispersion and attenuation, induced by fluid flow in porous media have attracted significant attention in reservoir exploration. To enhance the quantitative understanding of these features, various wave propagation mechanisms have been developed. It has...

A wavefield reconstruction method using sparse representation and dictionary learning for RTM

Pei, Chunyang; Shi, Linge; Li, Shiheng; Zhou, Xiaohua; Long, Yun; Chen, Zubin

2023 Journal of Geophysics and Engineering

doi:10.1093/jge/gxad059

Reverse time migration (RTM) is a well-established imaging technique that uses the two-way wave equation to achieve high-resolution imaging of complex subsurface media. However, when using RTM for reverse time extrapolation, a source wavefield needs to be stored for cross-correlation with the...

Micro-seismic monitoring using sparse planar array and a weak signal enhancement method

Yang, Xiaohui; Lin, Zhengliang; Yang, Xinchao; Chen, Zhanguo; Si, Wenpeng

2023 Journal of Geophysics and Engineering

doi:10.1093/jge/gxad060

Traditional ground micro-seismic monitoring is performed by laying long survey lines. This is expensive and difficult to implement in complex mountainous areas and deep marine shale gas reservoirs in China. To address these challenges, this study proposes a ground micro-seismic monitoring method...
