Deghosting of Marine Seismic Data Using Dual Sensor Technology
Haavik, Kjetil Eik (Master thesis, 2013)An inevitable phenomenon called the ghost reflection has always been a problem in marine seismic acquisition. The great contrast in acoustic properties over the air-water interface is causing an almost perfect reflection ... -
Iceberg ploughmarks illuminated by shallow gas in the central North Sea
Haavik, Kjetil Eik; Landrø, Martin (Journal article; Peer reviewed, 2014)Conventional 3D seismic data provides direct evidence for glacial influence during the early Pleistocenesedimentation in the Central North Sea. We identify iceberg ploughmarks as dim linear to curve-linearfeatures in three ... -
Source-Depth Diversity for Enhanced Marine Seismic Imaging
Haavik, Kjetil Eik (Doctoral theses at NTNU;2016:319, Doctoral thesis, 2016) -
Variable source depth acquisition for improved marine broadband seismic data
Haavik, Kjetil Eik; Landrø, Martin (Journal article; Peer reviewed, 2015-05)In marine seismic data acquisition, varying the source depth along a sail line gives diversity in sequential shot gather frequency spectra. Undesired alterations of the frequency spectra are created by the source ghost and ...
