  • Cross-streamer wavefield interpolation using deep convolutional networks 
    Greiner, Thomas Larsen; Kolbjørnsen, Odd; Lie, Jan Erik; Harris Nilsen, Espen; Kjeldsrud Evensen, Andreas; Gelius, Leiv-J. (Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2019)
    Seismic exploration in complex geological settings and shallow geological targets has led to a demand for higher spatial and temporal resolution in the final migrated image. Seismic data from conventional marine acquisition ...
  • Cross-streamer wavefield reconstruction through wavelet domain 
    Greiner, Thomas Larsen; Hlebnikov, Volodya; Lie, Jan Erik; Kolbjørnsen, Odd; Kjeldsrud Evensen, Andreas; Harris Nilsen, Espen; Vinje, Vetle; Gelius, Leiv-J. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
    Seismic exploration in complex geologic settings and shallow geologic targets has led to a demand for higher spatial and temporal resolution in the final migrated image. Conventional marine seismic and wide-azimuth data ...
  • Digital superresolution in seismic AVO inversion 
    Kolbjørnsen, Odd; Evensen, Andreas Kjelsrud; Nilsen, Espen Harris; Lie, Jan Erik (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    The sparseness promoted by the total variation norm is utilized to achieve superresolution amplitude-variation-with-offset (AVO) inversion. The total variation norm promotes solutions that have constant values within ...
