• Homotopy scattering series for seismic forward modelling with variable density and velocity 

      Xiang, Kui; Eikrem, Kjersti Solberg; Jakobsen, Morten; Nævdal, Geir (Journal article; Peer reviewed, 2021)
      We have derived a convergent scattering series solution for the frequency-domain wave equation in acoustic media with variable density and velocity. The convergent scattering series solution is based on the homotopy analysis ...
    • Point-spread function convolution to simulate prestack depth migrated images: A validation study 

      Jensen, Kristian; Lecomte, Isabelle Christine; Gelius, Leiv-J.; Kaschwich, Tina (Journal article; Peer reviewed, 2021)
      Seismic migration commonly yields an incomplete reconstruction of the Earth model due to restricted survey aperture, band-limited frequency content and propagation effects. This affects both illumination and resolution of ...
    • Seismic on floating ice: data acquisition versus flexural wave noise 

      Johansen, Tor Arne; Ruud, Bent Ole; Tømmerbakke, Ronny; Jensen, Kristian (Journal article; Peer reviewed, 2019)
      Geophysical surveying of the Arctic will become increasingly important in future prospecting and monitoring of the terrestrial and adjacent areas in this hemisphere. Seismic data acquired on floating ice are hampered with ...
