On the accuracy and spatial sampling of finite-difference modelling in discontinuous models
Tschache, Saskia; Vinje, Vetle; Iversen, Einar (Journal article; Peer reviewed, 2022)Finite-difference modelling estimates the wavefield in the subsurface by solving the elastic or acoustic wave equation numerically in a discrete version of the subsurface. The derivatives in the wave equation are approximated ... -
Source and receiver deghosting by demigration-based supervised learning
Jonge, Thomas de; Vinje, Vetle; Zhao, Peng; Poole, Gordon; Iversen, Einar (Journal article; Peer reviewed, 2022)Deghosting of marine seismic data is an important and challenging step in the seismic processing flow. We describe a novel approach to train a supervised convolutional neural network to perform joint source and receiver ...
