Broadband processing of conventional 3D seismic data for near surface geohazard investigation: A North Sea case study
Breistøl, Arv Håkon (Master thesis, 2015)3D exploration seismic data is increasingly being utilized for geohazard studies in the offshore oil and gas industry. An important criterion for the success of this approach is that the seismic data contain the broadest ... -
Diving-wave time-lapse delay for CO2 thin layer detection
Martinez Guzman, Ricardo Jose; Vinje, Vetle; Stovas, Alexei; Mispel, Joachim; Ringrose, Philip Stefan; Duffaut, Kenneth; Landrø, Martin (Peer reviewed; Journal article, 2024)We have derived an analytical approximate expression to estimate the delay in diving seismic waves due to thin layers of CO2. The expression is valid for high frequencies and can be used to estimate the delay in diving ... -
Estimating source signatures from source-over-spread marine seismic data
Helgebostad, Kristian; Landrø, Martin; Vinje, Vetle; Nilsen, Carl-Inge Colombo (Journal article; Peer reviewed, 2018)Recent developments in marine seismic acquisition include deploying a source vessel above a towed-streamer spread. We have developed an inversion algorithm to estimate source signatures for such acquisition configurations, ... -
Source Signature Estimation Based on Recordings in Deep-Towed Streamers Below the Source
Helgebostad, Kristian Svarva (Master thesis, 2017)Source-over-spread acquisition design is a recent development in marine seismic acquisition, aiming to improve imaging of the shallow subsurface. Contrary to conventional towed-streamer acquisition, source-over-spread ...
