Constrained non-linear AVO inversion based on the adjoint-state optimization
Ahmed, Nisar; Weibull, Wiktor Waldemar (Peer reviewed; Journal article, 2022)Pre-stack AVO inversion of seismic data is a modeling tool for estimating subsurface elastic properties. Our focus is on the model-based inversion method where then unknown variables are estimated by minimizing the misfit ... -
Frequency-dependent AVO inversion applied to physically based models for seismic attenuation
Ahmed, Nisar; Weibull, Wiktor Waldemar; Quintal, Beatriz; Grana, Dario; Bhakta, Tuhin (Peer reviewed; Journal article, 2022)Seismic inversion of amplitude versus offset (AVO) data in viscoelastic media can potentially provide high-resolution subsurface models of seismic velocities and attenuation from offset/angle seismic gathers. P- and S-wave ... -
Holistic 3D Model of an Urban Area in Norway: An Integration of Geophysical, Geotechnical, Remote Sensing, and Geological Methods
Gutierrez Mozo, Ivan David; Weibull, Wiktor Waldemar; Watson, Lisa; Olsen, Thomas Meldahl; Escalona Varela, Alejandro (Peer reviewed; Journal article, 2023)Understanding the distribution and characterization of natural and non-natural materials on the surface and near-subsurface is important for the development of infrastructure projects. This may be a challenge in highly ... -

Investigating the PS seismic imaging of faults using seismic modelling and data from the Snøhvit field, Barents Sea
Cunningham, Jennifer Elizabeth; Weibull, Wiktor Waldemar; Cardozo, Nestor; Iacopini, David (Peer reviewed; Journal article, 2021)PS seismic data from the Snøhvit field are compared with seismic modelling to understand the effect of azimuthal separation and incidence angle on the imaging of faults and associated horizon discontinuities. In addition, ... -
Time lapse seismic analysis of the Tohoku-Oki 2011 earthquake
Landrø, Martin; Kodaira, Shuichi; Fujiwara, toshiya; No, Tetsuo; Weibull, Wiktor Waldemar; Arntsen, Børge (Peer reviewed; Journal article, 2019)A detailed time lapse seismic analysis of subsurface movements is presented using seismic 2D lines acquired prior to and after the Tohoku-Oki earthquake offshore Japan in 2011. Estimated movements of the seabed from the ...
