Attenuating Random Noise in Seismic Data by a Deep Learning Approach

no code implementations28 Oct 2019 Xing Zhao, Ping Lu, Yanyan Zhang, Jianxiong Chen, Xiaoyang Li

In the geophysical field, seismic noise attenuation has been considered as a critical and long-standing problem, especially for the pre-stack data processing.

Enhanced Seismic Imaging with Predictive Neural Networks for Geophysics

no code implementations11 Aug 2019 Ping Lu, Yanyan Zhang, Jianxiong Chen, Yuan Xiao, George Zhao

In addition, in each iteration step, the probability cubes of salt bodies and inclusions inferred from the proposed networks can be used as a regularization term within the FWI forward modelling, which may result in an improved velocity model estimation while the output of seismic migration can be utilized as an input of the 3D neural network for subsequent iterations.

Finding Theme Communities from Database Networks
