    For economic and efficiency reasons, blended acquisition of seismic data is becoming increasingly commonplace. Seismic deblending methods are computationally demanding and normally consist of multiple processing steps. ...

    Marine seismic interference noise occurs when energy from nearby marine seismic source vessels is recorded during a seismic survey. Such noise tends to be well preserved over large distances and causes coherent artefacts ...
  • 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 ...
  • Waldeland, Anders Ueland; Zhao, Hao; Faccipieri, J. H.; Solberg, Anne H Schistad; Gelius, Leiv-J. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The common-reflection-surface (CRS) method offers a stack with higher signal-to-noise ratio at the cost of a time-consuming semblance search to obtain the stacking parameters. We have developed a fast method for extracting ...
  • Losnedahl, Sander Wågønes; Orji, Okwudili Chuks; Gelius, Leiv-J.; Sollner, Walter (Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2019)
    Traditional marine seismic sources are facing increasingly strict regulation due to their non-negligible environmental foot print. However, marine vibrators are easy to control, are more efficient and have lower environmental ...
  • Hlebnikov, Volodya; Elboth, Thomas; Vinje, Vetle; Gelius, Leiv-J. (Chapter / Bokkapittel / AcceptedVersion; Peer reviewed, 2019)
    In this work we demonstrate how onboard de-noise processing can improve survey efficiency by reducing the need for data re-acquisition. This is illustrated through a number of de-noising examples showing seismic interference, ...
